Preface 4: the strategy of the Civil War

Eben Swift, Lieutenant-Colonel 8th Cavalry, United States Army

A central strategical point — the approach to Richmond via James River, as it looked in war-time, blocked by the Confederate Ram “Virginia,” and gunboats “Patrick Henry” and “Jamestown,” sunk in the channel to hold the Federal fleet from Richmond (see two pages following for another view of this scene)

[110]

Obstructions rendered useless: James River, Virginia, near Drewry's Bluff.--1862 The superior navy of the Federals at the beginning and throughout the war enabled them to gain the advantage of penetrating the rivers leading into the interior of the Confederacy and thus support the military forces in many telling movements. To this fact the surrender of Forts Henry and Donelson and the ultimate control of the Mississippi by the Union forces gives eloquent testimony. In the East the regions between Washington and Richmond were traversed by streams, small and large, which made aggressive warfare difficult. For this reason McClellan chose the James River Peninsula for his first advance upon the Confederate Capital. Far more dreaded than the advance of the army was the approach of the powerful Monitor and the Galena up the James River, and the first thought of the Confederates was to hold this danger in abeyance. Hence the obstructions (shown on the opposite page) sunk in the bend of the James River near Drewry's Bluff, where a powerful battery known as Fort Darling was hastily but effectively constructed. These blocked the attempts of the Federals to invest the Confederate capital until Grant's superior strategy in 1864 rendered them useless by throwing his army across the James in one of his famous flanking movements and advancing toward Richmond in a new direction. The campaign developing into a siege of Petersburg on the Appomattox, the Federal vessels confined their activities to the lower James.

[111] [112]
But strategy, unfortunately, is a very unpopular science, even among soldiers, requiring both in practice and in demonstration constant and careful study of the map, the closest computation of time and space, a grasp of may factors, and the strictest attention to the various steps in the problems it presents. At the same time, it is a science which repays the student, although he may have no direct concern with military affairs; for not only will a comprehension of its immutable principles add a new interest to the records of stirring times and great achievements, but will make him a more useful citizen.--Stonewall Jackson and the Civil War, by Lieutenant-Colonel G. F. R. Henderson, C. B.

The student has great advantage over the actor in war, particularly when he makes his study after a lapse of fifty years. His point of view is illuminated then by the stories as told by both contestants, by the disputes and explanations of many participants. He also pursues his investigations without any of the distracting influences of war itself. It may not, therefore, be entirely fair to take each man's act before the bar of history and to require him to justify himself to the critics of a later day. In a larger sense, though, it is right, because past experience gives the best lessons and guides for the future. Until we have another war, we shall continue to study the great conflict of 1861-5, and to read the secrets of our future in its tale of failure or success.

“ Strategy” is a comparatively recent addition to our language. It is derived from the Greek στρατηγία, meaning generalship, and has several valuable derivatives, as “strategic” and “strategist,” which make it a more useful word than [113]

War students of two continents What an excellent example of open-air group portraiture — the work of Gardner's camera! But photography can add nothing to the fame of these men, gathered together in an idle hour to chat about the strategy of the war. Seated in the center is Count Zeppelin, of the Prussian Army, later the winner of honors with his airship and then on a visit to America to observe the Civil War. To his left is Lieutenant Rosencranz, a Swedish officer, on leave of absence, observing the war at close range as General McClellan's personal aide-de-camp. He successively served Burnside, Hooker and Meade in the same capacity. His brave and genial disposition made him a universal favorite. The other men are Americans, conspicuous actors as well as students in the struggle. On the ground, to the left, sits Major Ludlow, who commanded the colored brigade which, and under his direction, in the face of a continual bombardment, dug Dutch Gap Canal on the James. The man in the straw hat is Lieut. Colonel Dickinson, Assistant Adjutant General to Hooker, a position in which he served until the Battle of Gettysburg, where he was wounded. Standing is Captain Ulric Dahlgren, serving at the time on Meade's staff. Even the loss of a leg could not quell his indomitable spirit, and he subsequently sacrificed his life in an effort to release the Federal prisoners at Libby and Belle Isle.

[114] generalship. It means the art of the general and indicates the time, place, and way to fight battles.

The War of the States was viewed at first with indifference by foreign military men. For many years past, however, it has claimed their close attention, because they have come to realize that new conditions were tested then, and that new influences, which changed the art of the general even from the respected models of Napoleon fifty years before, were at work. Ironclads, entrenchments, railroads, the breech-loader, a new kind of cavalry were the fresh factors in the problem.

Although hostilities at first began over an area half as large as Europe, the region of decisive operations was, on account of lack of communication, narrowed to the country between the Atlantic and the Mississippi, about seven hundred miles in an air-line. The line was unequally divided by the towering barrier of the Alleghany Mountains, about two hundred miles wide, over which communication was difficult. The eastern section of the country beyond the range was about one hundred miles wide and the western section was about four hundred miles wide. In Maryland, northwestern Virginia, Kentucky, and Missouri sentiment was divided between the Union and the Confederacy. The Mississippi River separated three of the seceding States from the remaining eight.

The immense amount of supplies needed for a great army caused military operations on a large scale to be confined to rail and water lines. Of the former, both the North and South had several routes running east and west for lateral communication, and the South had several running north and south in each section, which could be used for lines of military-operations. In respect to water routes, the North soon demonstrated its complete control of the sea and was thus able to choose its points of attack, while interior water routes were available by the Mississippi, Tennessee, Cumberland, and James rivers. The advantage of the water route over that by rail was at once utilized by the Northern generals. [115]

A King's son in camp In 1861 there arrived the first great opportunity to study warfare in the field since the campaigns of Napoleon, and these young men of royal blood expected at no distant day to be the leaders of a war of their own to recover the lost Bourbon throne of France. The three distinguished guests of the Army of the Potomac seated at the farther end of the Camp dinner-table are, from right to left, the Prince de Joinville, son of King Louis Phillipe, and his two nephews, the Count de Paris and the Duc de Chartres, sons of the Duc d'orleans. They came to Washington in September, 1861, eager to take some part in the great conflict for the sake of the experience it would give them. President Lincoln welcomed them, bestowed upon each the honorary rank of Captain, and assigned them to the staff of General McClellan. Officially merely guests at headquarters, they acted as aides-de-Camp to McClellan, bearing despatches and the like, frequently under fire. They distinguished themselves at the battle of Gaines' Mill. The Prince de Joinville made a painting of that engagement which became widely published.

Learning the game In the lower picture the Count de Paris and the Duc de Chartres are trying their skill at dominoes after dinner. Captain Leclerc, on the left, and Captain Mohain, on the right, are of their party. A Union officer has taken the place of the Prince de Joinville. It was to perfect their skill in a greater and grimmer game that these young men came to America. At Yorktown they could see the rehabilitated fortifications of Cornwallis, which men of their own blood had helped to seize, now amplified by the latest methods of defensive warfare. Exposed to the fire of the Napoleon field pieces imported by the Confederacy, they could compare their effectiveness with that of the huge rifled Dahlgrens, the invention of an American admiral. General McClellan testified that ever in the thick of things they performed their duties to his entire satisfaction. At the close of the Peninsula Campaign the royal party returned to France, but watched the war with great interest to its close.

[116]

It was not so vulnerable to attack as the railroad. All navigable rivers within the area of operations were used for this purpose, and McClellan, Burnside, and Grant used the Chesapeake Bay and its tributaries to carry their base of supplies close to Richmond. The operations of the Confederates, on the other hand, were greatly restricted by being confined to railroad lines.

Several natural features which were certain to influence events to a great extent are to be noticed. In Virginia, numerous rivers, running parallel to the direct line of advance, form good lines for defense and also obstacles to an advance. Several mountain valleys leading north at the eastern ranges of the Alleghanies gave opportunities for leading large forces safely into Pennsylvania from Virginia, or vice versa. Within the mountain district, a railroad from Lynchburg, Virginia, to Chattanooga, in Tennessee, about four hundred miles long, gave an opportunity for transferring troops from one section to the other, while the corresponding distance at the North was three times as great. In the western section, the Tennessee and Cumberland rivers are separated at one place by a narrow neck about two miles wide, thus somewhat simplifying the problem of controlling these two important streams. The strategic chess-board, then, gave great opportunities to skilful generalship. The Virginia rivers gave strength to long defensive lines, screened marches from east to west, and forced the Northern generals to seek the flank rather than the front attack. The Shenandoah valley afforded a safe approach to Washington from the rear. This was availed of by Lee, Jackson, and Early to keep many thousand men of the army of the North in idleness. In the West, the long line defended by scattered troops was weak at every point and was quite easily broken by Grant, particularly when the South was slow in grasping the situation there. The advantage of the Richmond-Chattanooga railroad was not used by the Confederates until too late for success. [117]

Watching the war There is no mistaking the nationality of these Military Attaches with their tartans and Dundreary whiskers. They were accompanying the Army of the Potomac on its Peninsula Campaign. In the center of the group of Englishmen stands the Prince de Joinville. From the observations of these men both France and England were to learn many military lessons from a new conflict on the soil over which the soldiers of both nations had fought in a former generation. The armies of both North and South were being moved and maintained in the field in a manner and upon a scale undreamed of by Napoleon, to say nothing of Howe and Cornwallis. The Count de Paris wrote a very comprehensive and impartial history of the war, and in 1890 revisited America and gathered together some 200 or more surviving officers of the Army of the Potomac at a dinner in the old Hotel Plaza, New York City. Not half the veterans that were his guests more than two decades ago are still alive, and the Duc himself joined the majority in 1894.

Yorktown eighty years after Here are some English and other foreign military officers with General Barry and some of his staff before Yorktown in May, 1862. European military opinion was at first indifferent to the importance of the conflict as a school of war. The more progressive, nevertheless, realized that much was to be learned from it. The railroad and the telegraph were two untried elements in strategy. The ironclad gunboat and ram introduced serious complications in naval warfare. At first the influence of Napoleon I was manifest in the field, but as the struggle proceeded both armies developed distinctly new ideas of their own. The sight of Sherman maintaining railroad and telegraphic communications with a base 138 miles away was a new one to the world, while his cutting loose from any base whatever in his March to the Sea was only less remarkable than Lee's invasion of Pennsylvania under similar conditions, to which was added a superior opposing force. In these and many other examples the war set the pace for later development.

[118]

The strategy, on account of political and other influences, was not always chosen according to the best military principles. Such influences always exist, and it is the duty of the soldier to conform and to make his plan to suit as best he can.

Under the head of policy would come Lee's several invasions of the North, undertaken with insufficient forces and too far from his base of supplies. Numerous causes have been given for these campaigns, the most plausible of which were of a political and not of a strategic nature. It was thought that a victory won on Northern soil might lead to intervention on the part of foreign nations, or that it would increase the disaffected element in the North to such an extent that the South could dictate a peace.

The policy of making military operations conform to the desire to help Northern sympathizers in eastern Tennessee had a powerful influence on the entire war. In the spring of 1862, it would have taken Buell into eastern Tennessee, instead of to the assistance of Grant and would have changed the course of events in the Mississippi valley. Three months later, it was one of the potent influences that led to the breaking up of Halleck's army at Corinth. It finally caused Buell's relief from command because of his disapproval. It caused Burnside's army to be absent from the battle of Chickamauga.

In 1864, the campaigns of Price in Missouri and Hood in Tennessee are said to have been intended to affect the presidential election at the North by giving encouragement to the party which was claiming that the war was a Federal failure. If that was not the case might not Hood have done better by marching in the track of Longstreet through Knoxville, Tennessee, and Lynchburg, Virginia, to join Lee, while Sherman was marching to the sea, entirely out of reach?

An unreasonable importance, from a military point of view, was given to the capital of each government. The capital of the United States had been captured in two wars without producing more than local effect, but every plan in [119]

Scene of a peculiar military situation A remarkable panoramic view of a scene on James River taken in 1865, fifteen miles from Richmond. Farrar's Island is a point of land enclosed by an almost complete loop of the winding James. It is fifteen miles on a direct line from the former Confederate Capital, and by water, owing to the bends of the stream, some seven or eight miles more. When General Butler's Federal army had retreated from its futile attack on Drewry's Bluff, in May, 1864, to its strong entrenchments at Bermuda Hundred, southward, the military authorities, were in great fear that the Confederate flotilla and the ironclad ram Virginia No. 2 that was just being completed at Richmond would come down the stream, divide the army and separate it from its base. Much against the advice of many of the naval officers who commanded vessels of the Federal flotilla, obstructions were built across the channel almost from shore to shore at Trent's Reach, a broad stretch of water south of Farrar's Island. Further to strengthen the position, four strong Federal batteries were constructed on the river bank, batteries Wilcox, Parsons, Spofford and Sawyer. Only a mile and a half away to the west was the powerful Confederate Battery “Dantzler,” known as “Howlett's” to the Federal forces; from thence could be seen Forts Spofford and Sawyer. A peculiar situation was developed here. The Union obstructions and batteries were intended to prevent the Confederate fleet from coming down, and the Confederate engineers had placed mines and torpedoes in Trent's Reach to hinder the Federal fleet from coming up. The various strong forts along the river were for the same purpose, and at Chaffin's Bluff, less than three miles above Dutch Gap, the neck of Farrar's Island, the Confederate flotilla had penned itself in with obstructions quite as formidable as those below. Grant's later operations farther up the James and before Petersburg rendered much of the Federal work unnecessary.

[120]

Virginia was contingent upon the safety of Washington, thus causing the diversion of many thousand soldiers for that single duty. On the Southern side the correct military decision would have been to abandon Richmond as soon as Petersburg was invested, but the Government delayed, for political reasons, until it was too late, and the defending army surrendered as a consequence.

In the distribution of troops the Federal authorities were hampered by the rival claims of the border States, which thought they required protection. Hence, Ohio sent an army into West Virginia; Pennsylvania, into the Shenandoah valley; the national Government concentrated troops for the protection of its capital; the Western States gathered along the Ohio River and in Missouri. This great dispersion existed on both sides and continued more or less till the end of the war. The advantage it gave was in the protection of the friendly portion of the population and in the good recruiting ground thus secured. The great difficulty of holding troops in service, whose home country had been overrun, was appreciated by both sides and exercised a strong influence on the plans of the generals. These conditions dictated much of the strategy which is subject to criticism, and should not be forgotten.

The policy of furloughing great numbers of soldiers during the war, as an inducement to reenlist, was probably unavoidable, but it helped to cause inactivity during many months and in the case of Sherman's Atlanta campaign it caused the absence of two of his divisions. Absenteeism is one of the inevitable consequences of a long war, with troops untrained in time of peace by modern methods. Lincoln complained of it and the generals seemed powerless to limit or prevent it. Probably the latter are entitled to most of the blame. It was not uncommon for a general to call for reenforcements at a time when large numbers of his troops were absent.

The armies were indeed long in getting over the [121]

The key to Washington From Chattanooga, Tennessee, to Harper's Ferry, Virginia, lay the Alleghany Mountains, an almost impassable barrier to the movement of armies. Here we see them sloping toward the gap at Harper's Ferry on the Potomac. The approach to this was made easy from the South by the Shenandoah Valley, the facile and favorite avenue of advance by the Confederates when threatening invasion of the enemy's territory. The scene is of the dismantled bridge across Armstrong Run. Driving General Banks' forces up the Valley and forcing him across the Potomac, Jackson saved Richmond from McClellan in 1862. Up the Valley came Lee the following year, striking terror to the North by the invasion that was only checked at Gettysburg. This eastern gap, provided by nature in the Alleghanies, became a veritable gateway of terror to the Federals, for through it lay open the path for sudden approach upon Washington on the part of the Confederates.

[122] characteristics of raw troops, but the generals in their early movements do not appear much better than the troops. Every man who had been graduated from West Point was regarded as a “trained soldier,” which was a mistake, because West Point was a preparatory school, and such men as had studied the art of high command had done so by themselves. The trade of the general was new to all, and had to be learned in the hard school of experience.

In four of the early campaigns in which the Federal troops were practically unopposed, they marched on an average of less than seven miles per day, while, in case of opposition by a greatly inferior force, the average was down to a mile a day, as in the Peninsula campaign and the advance on Corinth.

The plans for the early battles were complicated in the extreme, perhaps due to the study of Napoleon and his perfect army opposed by poor generals. Bull Run, Wilson's Creek, Seven Pines, Glendale, Malvern Hill, Shiloh, Gaines' Mill were of this kind, and failed. Even at Gettysburg, July 2, 1863, Lee's failure to execute his echelon attacks showed that his army was not yet ready to perform such a delicate refinement of war.

As an example of improvement, however, take Jackson's march of fourteen miles on a country road and the battle fought on May 2, 1863, all between daylight and dark of one day. In battles, also, we notice the fine play of early campaigns replaced by a savage directness and simplicity at a later period, in the Wilderness by Lee and at Spottsylvania by Grant. Thus it was that both leaders had ceased to count on the inefficiency of the enemy. At the beginning of the movement on Richmond both Lee and Grant seemed reckless in the risks they took. It was not so earlier.

The earliest form of strategy was the practice of ruse, stratagem, and surprise, but they have long been considered as clumsy expedients which are no longer effective against [123]

Richmond and Washington.

In these two pictures appear the two capitals that were mistakenly made the goals of the military operations on both sides. The Confederates threatened Washington at the outset of the war, and realizing the effectiveness of such a move in giving moral rather than military support to their cause, similar movements were repeated throughout the war. For a like reason “On to Richmond” was the cry at the North until Grant took command and made the army of Lee and its ultimate reduction to an ineffective state his controlling purpose. With the investment of Petersburg by the Federals, Lee's proper military move would have been the abandonment of Richmond and the opposing of Grant along other lines.

Political objectives, Washington


 
[124] the best troops and commanders. Among instances which are often classed in this category are Shiloh, Chancellorsville, and the Wilderness.

Some forms of strategy have not changed in several thousand years. Sherman, for instance, crossed the Chattahoochee, which was held by Johnston, in 1864, in the same way that Alexander crossed the Hydaspes in the year 326 B. C., by feinting at one flank and crossing at the other.

The Vicksburg campaign gave great fame to General Grant and is really one of the most complete and decisive examples in history. In this campaign, he deliberately crossed the river north of Vicksburg, marched south and crossed again below Vicksburg. Then, relying on the country for supplies, he moved to Jackson, forty-five miles east of Vicksburg, where he interposed between the fractions of the Confederate army under Pemberton and Johnston. He then turned back again toward the Mississippi, drove Pemberton into Vicksburg, established a base of supplies at the North and invested the city. In this case, it is noticeable that the tendency to rate localities at too high a value is shown in Pemberton's retreating to Vicksburg, which was quite certain to be surrendered, instead of joining forces with Johnston to oppose Grant in the interior.

The same point is illustrated by the siege of Petersburg. As soon as Grant's army crossed the James and began this siege the fate of Richmond was sealed, for Grant had a great army and numerous means of extending his fortified lines until they crossed every avenue of approach to Richmond.

Moltke remarked that strategy was nothing more than common sense, but he acknowledged that it was often difficult to decide what was common sense and what was not. He might easily have had our Civil War in his mind. In 1861, the art of war had been greatly complicated by pedantic study, principally by officers of the French school, in attempting to reduce it to an exact science. The true lesson of Napoleon's [125]

Defense of Washington.

Only once were the elaborate fortifications about Washington seriously threatened. That was when the Confederate General Jubal A. Early, with a force of 10,000 men, marched against the Federal capital in July, 1864, with the intention of capturing it. Reinforcements were rushed to these works and Early retreated. The constant compliance with the clamor at the North that Washington be strongly defended was a serious strategical mistake. The Army of the Potomac was at first superior in number to Lee's army of Northern Virginia. It could have been made overwhelmingly so at the beginning of the war if the troops around Washington had been added to it. Grant demonstrated the wisdom of this policy in 1864 by leaving only a few heavy artillery regiments, the “hundred days men,” and detachments from the Veteran Reserve to defend Washington. He then outnumbered Lee in the field.

A defender of the Federal capital

An idle garrison


 
[126] campaigns had either been lost or the effect of new conditions had not been appreciated. It seems rather commonplace to say at this time that the first thing to do in war is to decide on your objective, but in the Civil War an incalculable amount of time was wasted, much treasure expended, and many lives were lost in a blind search for an objective. By objective is meant, of course, a point upon which to concentrate the greatest effort, the gaining of which will mean the success or failure of the cause.

In 1862, when the hostile armies opposed each other in front of Washington, McClellan insisted on attacking Richmond instead of Johnston's army. His plan resulted in the transfer of his army to the Peninsula and carried him to within six miles of Richmond with insignificant loss. For this, great credit has been claimed and unfavorable comment made on later campaigns. But McClellan found the undefeated Confederate army at Richmond, and he was weakened by a vast army which had been kept back to guard Washington. Without entering into this great controversy, we may simply say that to fight the foe as far from Richmond as possible would now be considered the correct solution of that problem. It is well known that Lincoln disapproved of McClellan's plan, whether by the counsel of wise military advisers or by his own common sense we know not.

Again, in 1862, when Halleck with much trouble and skill had collected a great army of one hundred thousand men at Corinth, the army was dispersed, contrary to his desire, it appears, and the true objective was lost. The Confederate leader repaired his losses and soon recovered from his serious defeats. At that time the army could have gone anywhere, whether to Vicksburg to open the Mississippi, or to Chattanooga and even to Richmond. This is the opinion of those best qualified to know. Burnside, also, in the fall of 1862, marched away from Lee's army when he went to Fredericksburg. [127]

Where Grant crossed the James. When Grant at this point crossed the James and, ignoring the water approaches upon Richmond, proceeded to the investment of Petersburg, Lee was as good as checkmated. For months Grant's brilliant flanking movements had gained him no advantage over his opponent, who persistently remaining on the defensive shifted from one impregnable position to another till at last Grant saw that the railroads were the key to the situation. With Lee's forces entirely disposed for the defense of Richmond, it was but necessary to cut off the communications of the Confederate capital in order to force Lee to come forth and give battle. The investment of Petersburg, successfully prosecuted, would leave but one railroad in the hands of the Confederates. The crossing of the James near Wilcox Landing over the bridge, the remains of which appear in the picture, was the final strategic triumph by which Grant accomplished victory over Lee's army.

[128]

So deep-rooted is the idea of choosing a locality as the objective of a campaign instead of a hostile army, that Rosecrans' campaign, in the summer of 1863, has gone into history as the “Campaign for Chattanooga,” and it has been claimed by his admirers that the possession of that place was worth what it cost — a heavy defeat at Chickamauga.

In 1864, Grant had authority to lay down a choice of objective, which he had already announced in 1862. For himself it was clearly Lee's army, and it was intended to be the same with other commands as well. General Sherman, however, was not so clear in his manner of execution as was his chief. His strategy creates a suspicion that it was designed to force Johnston to retreat and to relinquish territory. There was an idea that Johnston would not give up Dalton, which he had strongly fortified, but Sherman's heavy turning movement against his rear forced him to retreat without a battle. The same strategy continued until Atlanta was reached, and still Johnston's army was undefeated, while Sherman had weakened his army by guarding a long line of communication. Judging from this, we are disposed to suspect that Atlanta, rather than Johnston's army, was Sherman's main objective.

Later, the historic “March to the sea” introduces a novel element into the question, for Sherman abandoned Hood's army as a first objective, and chose Lee's army instead. It will be remembered that Sherman had difficulty in getting consent from Grant, who wanted him to ruin Hood's army first. As it turned out, Sherman marched one thousand miles and was several hundred miles from Lee at the end of the campaign. If Lee's army had been his real objective there were other ways of reaching it: first, by sending his army by sea north from Savannah, as was suggested by Grant, which would have taken two months, say until the end of February, 1865; second, by sending the troops by rail, as Schofield was moved with fifteen thousand men and as Hooker was moved with twenty-three thousand men, and, third, by marching on [129]

Sherman's famous feint. Railroad Bridge over the Chattahoochee, 1863 In the foreground we see the formidable defenses behind which Johnston held the railroad bridge over the Chattahoochee against the advance of Sherman upon Atlanta. At this river Sherman exemplified again the strategy of Alexander at the Hydaspes. While Johnston with all his forces save cavalry was lying menacingly at the head of this bridge, Sherman, feinting strongly against his right with Stoneman's cavalry as if determined to gain a crossing, meanwhile quickly shifted the main body of his army to the left of Johnston's position, crossed the river on pontoons and immediately established a tete du pont of his own in Johnston's rear capable of withstanding his entire force. There was nothing for Johnston but to retreat upon Atlanta, burning the bridge behind him. In the picture is the bridge as rebuilt by Sherman's engineers, another link in his long line of communication by rail.

Lynchburg by the Knoxville road, which would have been about one-third to one-half the distance actually marched.

Looking upon the war with all the advantage of to-day, it is not difficult to assume that the hopes of both sides rested on two great armies, one in the East and one in the West, and the destruction of either meant the destruction of the other. This clear estimate seems to have come quite naturally and easily to only one man during the war, and that man was Grant. Such a conception clears away a mass of secondary objectives, such as so-called “strategic points” along the coast and west of the Mississippi, which consumed hundreds of thousands of troops and had only a minor effect on the final issue. It must be admitted that Grant used some seventy-five thousand men on secondary objectives which were not successful, in 1864, when these men would have had a great effect either with the armies of Sherman or himself. He probably thought that an army of one hundred and twenty thousand men was large enough for his purposes, but he found it was a mistake.

Equally fallacious with the importance given to “strategic points” was that ascribed to the occupation of territory. The control of Kentucky and Tennessee was given by Grant's Fort Donelson campaign, but the injury inflicted on the Confederate army by the large capture of men at Donelson and Island Number10 was the real and vital result. The control of territory that was not accompanied by the defeat of the foe often had many disadvantages. Such was the experience of Grant and Sherman, the former in his first advance on Vicksburg, and the latter in the Atlanta campaign.

For the South it was an easier task to decide upon an objective because it was the weaker side and its acts were determined by those of the stronger. The main idea of the strategy of the Southern generals was to divert attention to side issues, to induce the opposing general to weaken his forces at decisive points. Numerous examples of diversions are afforded by Jackson's Valley Campaign, in 1862, which kept many [131]

Engineers and the railroads.

The great Civil War first introduced the railroad as a strategic factor in military operations. In the first picture we see the Federal engineers at Vibbard Draw on Long Bridge at Washington busily at work rehabilitating a locomotive for use along the railroad connections of the capital with its army. Extemporized wooden structures of that time seem paltry in comparison with the great steel cranes and derricks which our modern wrecking trains have made familiar. The railroads in control of the North were much better equipped and guarded than those of the South, yet the bold Confederate Cavalry, under such leaders as Stuart, were ever ready for raids to cut communications. How thoroughly they did their work whenever they got the chance, the lower picture tells.

[132] thousand men away from McClellan; Early's march on Washington, and many cavalry raids.

The result of a study of objectives shows that, with good troops, and safe, but not brilliant, generals on both sides, the only way to overthrow the opponent is to attack and defeat his main army.

The long periods of inactivity in the several armies of the North seem to have been largely, but not always, due to the frequent change of commanders. The other causes would take long to analyze. Lee made six campaigns in fourteen months, from May, 1862, to July, 1863, a performance unequaled in history. But McClellan's army was inactive for ten months after Bull Run; Rosecrans' army for five months after Murfreesboro, and Grant's army for four months after Vicksburg, while Grant's army was almost in the same class during its ten months before Petersburg.

The concentration of scattered forces at decisive points, which is technically called in the text-book the use of interior lines, and in more homely phrase, “getting there first with the most men,” was often skilfully performed on both a large and small scale. Thus, Johnston joined Beauregard at Bull Run in time to win the battle; Jackson alternately attacked the divided forces of his opponents and neutralized their greatly superior forces, and finally joined Lee for another campaign; Longstreet joined Bragg to win Chickamauga; Ewell joined Breckinridge to defeat Sigel. Many opportunities were lost, even in the very campaigns mentioned, as we see them to-day.

The conduct of pursuits confirms the idea that it is the most difficult operation presented to a general. Johnston after Bull Run, McClellan after Antietam, Meade after Gettysburg, Bragg after Chickamauga, Grant after Chattanooga, and Lee after Fredericksburg practically allowed the defeated enemy to escape without further injury. Lee's pursuit of McClellan in the Seven Days Battles on the Peninsula and of Meade in [133]

Military commerce.

This view of the magazine wharf at City Point in 1864 reveals the immensity of the transportation problem that was solved by the North in support of its armies in the field. The Federal army in Virginia, unlike the armies of Napoleon, did not forage off the territory which it occupied. Rail and water transportation made possible the bringing of supplies long distances. Whatever point was chosen for the army base quickly became a bustling center, rivaling the activity of any great commercial city, and giving employment to thousands of men whose business it was to unload and forward the arriving stores and ammunition to the army in the field near by.

When Grant finally settled down to the siege of Petersburg, and City Point became the army base, the little village was turned temporarily into a great town. Winter quarters were built in the form of comfortable cabins for the reserve troops and the garrison, and ample hospital buildings were provided. The railroad to Petersburg was controlled and operated by the army for the forwarding of troops and stores. The supply base longest occupied by the Army of the Potomac, City Point, grew up almost in a night. With the coming of peace the importance of the post vanished, and with it soon after the evidences of its aggrandizement.

ø [134] the operations of October, 1863, had only partial success. Near the end of the war Thomas' pursuit of Hood, after Nashville, showed a much higher efficiency than had yet been reached, and the Appomattox campaign gives the only entirely successful instance in about one hundred years of military history.

The campaigns of Lee and Jackson were models of their kind. Napoleon has said that the general who makes no mistakes never goes to war. The critic of Lee finds it hard to detect mistakes. No general since Hannibal, and perhaps Napoleon, in the last two years of his campaigns, has made war under greater disadvantages and accomplished so much with an inferior force. While all great generals before him inherited a ready-made army, Lee, like Washington, made his own army. He fought soldiers of the same race and generals of the same school as himself. His genius was shown in many ways, but nowhere more than in his ability to calculate chances, even when he was violating the so-called rules of war. He used converging columns which met upon the field of battle; he detached inferior forces against the Federals' rear; he divided his army in the presence of the foe; he uncovered his lines of retreat and fought battles in that position; he did not hesitate to throw his last reserve into the fight.

On two occasions he withdrew his army across the Potomac River, in good order and without loss, in the presence of a powerful hostile army. His use of the ground to compensate for inferior numbers and to hide his movements from the Federals shows how clearly he saw the secrets of Napoleon's generalship, while his battles in the woods were entirely original and his use of entrenchments was effective. The power of the modern fire-arm in the hands of his opponents forced him to accept less decisive results than great soldiers who preceded him. As with other great soldiers, his best success was due to the inefficiency of his opponents in the early days. He was probably the last of the race of generals who, like Napoleon, dominated the field of war by genius alone. He [135]

Formidable fieldworks: new necessities of warfare.

The increased deadliness of firearms taught the commanders in the Civil War the habit of greatly strengthening every new position occupied with earthworks as formidable as possible. The works in the first picture were thrown up in a night by the Federals near North Anna River, Virginia, in 1864. It is apparent how they would strengthen the resistance of a small force to larger numbers who might advance across the open upon the position. In the second picture we see the salient of “Fort Hell,” with its ditch and abattis and breastworks constructed of gabions, the result of many days' work of the soldiers in anticipation of attack. This was one of the fortifications about Petersburg, where the construction of fieldworks was developed to the highest point of efficiency.

[136] will be replaced by the safe leader who is never brilliant, but makes no mistakes and at the same time commands the heaviest battalions.

The absence of a broad and comprehensive plan of operations was particularly noticeable on both sides. It never seemed to have been developed in the North until Grant issued his orders for a general advance, in 1864. In the South, Longstreet seems to have prepared a strategic plan for the movement of all Confederate armies after Chancellorsville, but this was not approved. The immense area occupied by the opposing forces, greater than had ever before been occupied in a single war, may be the excuse for this.

Great fame has come to the various generals who each made some well-planned maneuver, which forced the foe to relinquish territory and retreat to a rear position. McClellan before Manassas, Rosecrans before Shelbyville, and Sherman before Dalton did all this, but it is a debatable question whether the final issue was hastened or delayed.

Sherman gained Atlanta with a loss of thirty-two thousand men, and Rosecrans gained Chattanooga with a loss of eighteen thousand men, but the foe was not defeated. On the other hand, Grant, in his year from the Rapidan to Appomattox accomplished the desired result, but with severe losses, it is true.

After all is said, the subject may be narrowed down to the statement that Lee, Jackson, and perhaps Johnston handled inferior forces with as great skill as any commanders since Hannibal and Napoleon.

On the other side it was also an American soldier, even before Sedan and Mukden, who formulated the modern idea of strategy which has been so closely followed in recent wars — to seek out the foe, get close to him, and fight it out by short-arm jolts.
