consisted of seven divisions, with detached troops for guarding his communications, maintaining order, and otherwise providing for his safety, and amounted, in the aggregate, to 94,783 men of all arms.
The army presented an effective force for the field of 73,472 men, of which 60,882 were infantry, 9237 cavalry, and 3368 artillery, with twenty-eight field and two siege batteries of six guns each.1
On the 15th Buell
commenced his march, with five divisions, as already stated, to effect leisurely the junction ordered by General Halleck
; while one division, the 7th, under General G. W. Morgan
, went to East Tennessee
, and another, the 3d, under General O. M. Mitchell
, to pursue General Johnston
and destroy the Memphis and Charleston Railroad south of Fayetteville
Neither of these last-named operations was performed with much celerity.
On arriving at Columbia
, forty miles south of Nashville
, General Buell
found the bridge across Duck River
destroyed, and the water too high to ford.
He was delayed there until the morning of the 29th, when, the bridge having been rebuilt, he again started for Savannah
, thence to Pittsburg Landing
, a distance of about one hundred miles, which he accomplished in nine days, marching slightly more than eleven miles a day. His head of column, Nelson
's division, arrived at Pittsburg Landing
at 3 o'clock P. M. on the 6th of April, the march from Savannah
having been hurried in order to reach the field of Shiloh
, from which the sound of the battle was plainly heard.
The united armies of Grant
(his five divisions) would have presented a well-disciplined and fully equipped force of about 84,000 men. Against this we could not possibly bring more than 38,500 infantry and artillery, 4300 cavalry, and fifty field guns.
This estimate excludes 7000 men at Island No.10
and vicinity, who were indispensable to hold at bay Pope
's army of over 20,000 men, and to keep control of the Mississippi River
at that point.
Moreover, the forces General Beauregard
had hastily collected (about 25,000 strong) were imperfectly armed, insufficiently drilled, and only partly disciplined.
They had but recently been organized into two corps, under Generals Polk
, composed of two divisions each.
