Doc. 154.-the riot at St. Louis, Mo., May 10, 1861.The camp of Gen. Frost, at Lindell's Grove, was a camp of instruction, intended to be continued for the term of six days, and which was formed in pursuance of orders from the governor of the State, who had directed the other militia districts also to go into encampments, with the view of acquiring a greater degree of proficiency in military drill. The encampment was commenced on the 4th instant.
St. Louis, May 10.Unusual, and to some extent alarming, activity prevailed early yesterday morning at each rendezvous of the “Home Guard,” and in the vicinity of the Arsenal. The men recently provided with arms from the Arsenal, to the number of several thousands, were ordered, we understand, to be at their different posts at 12 o'clock, in readiness to march as they might be commanded. A report gained some currency that Gen. Harney was expected on the afternoon train, and that the troops were to cross the river to receive him, and escort him to the city. Very little reliance, however, was placed in this explanation of the military movements, and at about 2 o'clock P. M., the whole town became greatly agitated upon the circulation of the intelligence that some five or six thousand men were marching up Market street, under arms, in the direction of Camp Jackson. The news proved to be correct, except as to the numbers, and in this case the report rather under-estimated the extent of the force. According to our best information, there were probably not less than seven thousand men under Capt. Lyon, (commanding the United States troops at this post,) with about twenty pieces of artillery. The troops, as stated before, marched at quick time up Market street, and on arriving near Camp Jackson, rapidly surrounded it, planting batteries upon all the heights overlooking the camp. Long files of men were stationed in platoons at various points on every side, and a picket guard established covering an area of say two hundred yards. The guards, with fixed bayonets, and muskets at half cock, were instructed to allow none to pass or repass within the limits thus taken up. By this time an immense crowd of people had assembled in the vicinity, having gone thither in carriages, buggies, rail-cars, baggage-wagons, on horseback, and on foot. Numbers of men seized rifles, shot-guns, or whatever other weapons they could lay hands upon, and rushed pell-mell to the assistance of the State troops, but were, of course, obstructed in their design. The hills, of which there are a number in the neighborhood, were literally black with people — hundreds of ladies and children stationing themselves with the throng, but as they thought out of harm's way. Gen. Frost, commanding Camp Jackson, received the intelligence of the advance of the Arsenal troops with equanimity, but with some astonishment. Hie had heard reports that it was the design of Capt. Lyon to attack his camp, but was not at first disposed to place credence in them. So rapidly did these rumors come to him, however, that yesterday morning he addressed Capt. L. a note of which the following is a copy:
Capt. L. refused to receive the above communication. He forwarded Gen. Frost the following about the time, if we are not mistaken, of the surrounding of his camp:Headquarters, Camp Jackson, Missouri Militia, May 10, 1861.Sir: I am constantly in receipt of information that you contemplate an attack upon my camp, whilst I understand that you are impressed with the idea that an attack upon the Arsenal and United States troops is intended on the part of the militia of Missouri. I am greatly at a loss to know what could justify you in attacking citizens of the United States who are in the lawful performance of duties devolving upon them under the Constitution, in organizing and instructing the militia of the State in obedience to her laws, and therefore have been disposed to doubt the correctness of the information I have received. I would be glad to know from you personally whether there is any truth in the statements that are constantly poured into my ears. So far as regards any hostility being intended towards the United States, or its property or representatives, by any portion of my command, or, as far as I can learn, (and I think I am fully informed,) of any other part of the State forces, I can say positively that the idea has never been entertained. On the contrary, prior to your taking command of the Arsenal, I proffered to Major Bell, then in command of  the very few troops constituting its guard, the service of myself and all my command, and, if necessary, the whole power of the State to protect the United States in the full possession of all her property. Upon Gen. Harney's taking command of this department, I made the same proffer of services to him, and authorized his Adjutant-General, Capt. Williams, to communicate the fact that such had been done to the War Department. I have had no occasion since to change any of the views I entertained at that time, neither of my own volition nor through orders of my constitutional commander. I trust that after this explicit statement we may be able, by fully understanding each other, to keep far from our borders the misfortunes which so unhappily afflict our common country. This communication will be handed to you by Col. Bowen, my Chief of Staff, who will be able to explain any thing not fully set forth in the foregoing. I am, sir, very respectfully, your obedient servant,
Captain N. Lyon, Commanding United States Troops in and about St. Louis Arsenal.Brig. Gen. D. M. Frost, Commanding Camp Jackson, M. V. M.
Immediately on the receipt of the foregoing, Gen. Frost called a hasty consultation of the officers of his staff. The conclusion arrived at was that the brigade was in no condition to make resistance to a force so numerically superior, and that only one course could be pursued — a surrender. The demand of Capt. Lyon was accordingly agreed to. The State troops were therefore made prisoners of war, but an offer was made to release them on condition that they would take an oath to support the Constitution of the United States and would swear not to take up arms against the Government. These terms were made known to the several commands, and the opportunity given to all who might feel disposed to accede to them to do so. Some eight or ten men signified their willingness; but the remainder, about eight hundred, preferred, under the circumstances, to become prisoners. (A number of the troops were absent from the camp in the city on leave.) Those who declined to take the prescribed oath said that they had already sworn allegiance to the United States and to defend the Government, and to repeat it now would be to admit that they had been in rebellion, which they would not concede. The preparations for the surrender and for marching, as prisoners, under the escort of the Arsenal troops, occupied an hour or two. About half-past 5 the prisoners left the grove and entered the road, the United States soldiers enclosing them by a single file stretched along each side of the line. A halt was ordered and the troops remained standing in the position they had deployed into the road. The head of the column at the time rested opposite a small hill on the left as you approach the city, and the rear was on a line with the entrance to the grove. Vast crowds of people covered the surrounding grounds and every fence and housetop in the vicinity. Suddenly the sharp reports of several firearms were heard from the front of the column, and the spectators that lined the adjacent hill were seen fleeing in the greatest dismay and terror. It appeared that several members of one of the German companies, on being pressed by the crowd and receiving some blows from them, turned and discharged their pieces. Fortunately no one was injured, and the soldiers who had done the act were at once placed under arrest. Hardly, however, had tranquillity been restored when volley after volley of rifle reports were suddenly heard from the extreme rear ranks, and men, women, and children were beheld running wildly and frantically away from the scene. Many, while running, were suddenly struck to the sod, and the  wounded and dying made the late beautiful field look like a battle-ground. The wounded, who were unable to be moved, were suitably cared for on the grounds. The total number killed and injured was about twenty-five. It was reported that the Arsenal troops were attacked with stones, and a couple of shots discharged at them by the crowd before they fired. The most of the people exposed to the fire of the soldiers were citizens with their wives and children, who were merely spectators, and took no part in any demonstration whatever. The firing was said to have been done by Boernstein's company, and at the command of an officer. The United States troops are now in possession of Camp Jackson, with all the equipage, tents, provisions, &c. The prisoners of war are, we believe, at the Arsenal. It is almost impossible to describe the intense exhibition of feeling which was manifested in the city. All the most frequented streets and avenues were thronged with citizens in the highest state of excitement, and loud huzzas and occasional shots were heard in various localities. Thousands upon thousands of restless human beings could be seen from almost every point on Fourth street, all in search of the latest news. Imprecations, loud and long, were hurled into the darkening air, and the most unanimous resentment was expressed on all sides at the manner of firing into the harmless crowds near Camp Jackson. Hon. J. R. Barret, Major Uriel Wright, and other speakers addressed a large and intensely excited crowd in front of the Planters' House, and other well-known citizens were similarly engaged at various other points in the city. All the drinking saloons, restaurants, and other public resorts of similar character were closed by their proprietors, almost simultaneously, at dark; and the windows of private dwellings were fastened in fear of a general riot. Theatres and other public places of amusement were entirely out of the question, and nobody went near them. Matters of graver import were occupying the minds of the citizens, and every thing but the present excitement was banished from their thoughts. Crowds of men rushed through the principal thoroughfares, bearing banners and devices suitable to their several fancies, and by turns cheering and groaning. Some were armed and others were not armed, and all seemed anxious to be at work. A charge was made on the gun-store of H. E. Dimick, on Main street, the door was broken open, and the crowd secured fifteen or twenty guns before a sufficient number of police could be collected to arrest the proceedings. Chief McDonough marched down with about twenty policemen, armed with muskets, and succeeded in dispersing the mob and protecting the premises from further molestations. Squads of armed policemen were stationed at several of the most public corners, and the offices of the Missouri Democrat and Anzeiger des Westens were placed under guard for protection.Headquarters, United States troops, St. Louis, (Mo.,) May 10, 1861.Sir: Your command is regarded as evidently hostile towards the Government of the United States. It is, for the most part, made up of those secessionists who have openly avowed their hostility to the General Government, and have been plotting at the seizure of its property and the overthrow of its authority. You are openly in communication with the so-called Southern Confederacy, which is now at war with the United States, and you are receiving at your camp, from the said Confederacy and under its flag, large supplies of the material of war, most of which is known to be the property of the United States. These extraordinary preparations plainly indicate none other than the well-known purpose of the Governor of this State, under whose orders you are acting, and whose purpose recently communicated to the Legislature, has just been responded to by that body in the most unparalleled legislation, having in direct view hostilities to the General Government and co-operation with its enemies. In view of these considerations, and of your failure to disperse in obedience to the proclamation of the President, and of the eminent necessities of State policy and welfare, and the obligations imposed upon me by instructions from Washington, it is my duty to demand, and I do hereby demand of you an immediate surrender of your command, with no other conditions than that all persons surrendering under this demand shall be humanely and kindly treated. Believing myself prepared to enforce this demand, one-half hour's time, before doing so, will be allowed for your compliance therewith. Very respectfully, your obedient servant,
Gen. D. M. Frost, Commanding Camp Jackson:N. Lyon, Captain, 2d Infantry, Commanding Troops.
