Headquarters Porter's Division,
Third Army Corps.
Camp near Yorktown, April 6, 1862.

Col. Berdan, Commanding Sharp Shooters:

Colonel.—The Commanding General instructs me to say to you that he is glad to learn, from the admissions of the enemy themselves, that they begin to fear your sharp shooters. Your men have caused a number of the rebels to bite the dust. The Commanding General is glad to find your corps are proving themselves so efficient, and trusts that this intelligence will encourage your men, give them, if possible, steadier hands and clearer eyes, so that when their trusty rifles are pointed at the foe, there will be one rebel less at every discharge. I am, Colonel, very respectfully, your obedient servant,

FRED. T. LOCKE, A. A. G.

Gen. McClellan, believing the place too strong to be carried by assault, and his plans for turning the position having been disarranged by the detention in front of Washington of Gen. McDowell's corps, to which he had entrusted the movement, the army went into camp and settled down to the siege of Yorktown. The ensuing thirty days were full of excitement and danger, and Co. F had its full share. Several of the companies were detached and ordered to other portions of the army. Co. F, however, remained at regimental headquarters. Heavy details were made every day for service in the rifle pits, the men leaving camp and occupying their positions before daylight, and being relieved by details from other regiments after dark. Details were also frequently made for the purpose of digging advanced rifle pits during the night. These pits were approached by zigzags, and could only be reached during the hours of daylight by crawling on the hands and knees, and then only under circumstances of great danger. They were pushed so far to the front that, when the evacuation took place on the night of the 3d of May, they were hardly more than one hundred yards from the main rebel line of works, and hardly half as far from the rebel rifle pits. Frequent sharp conflicts took place between bodies of rebel and Union soldiers striving for the same position on which to dig a new rifle pit, in several of which Co. F took a prominent part and suffered some loss.

So close were the opposing lines at some places that sharp shooting became almost impossible for either side, as the exposure of so much as a hand meant a certain wound.

In this state of affairs the men would improvise loop holes by forcing sharpened stakes through the bank of earth in front of the pits, through which they would thrust the barrels of their breach loaders, over which they would keenly watch for a chance for a shot, and woe to that unfortunate rebel who exposed even a small portion of his figure within the circumscribed range of their vision.

The regimental camp before Yorktown was beautifully situated near the York river and not far from army headquarters. Great rivalry existed between the different companies as to which company street should present the neatest appearance, and the camp was very attractive to visitors and others. The officers mess was open to all comers and was a constant scene of visiting and feasting. For a few days, it is true, the troops, officers and men alike, were on short rations, but as soon as the river was opened and docks constructed, the necessities, and even the luxuries of life were abundant. At this camp the first instalment of the much desired and long promised Sharpe rifles arrived. Only one hundred were received in the first consignment, and they were at once issued to Co. F as an evidence of the high esteem in which that company was held by the officers of the regiment, and as a recognition of its particularly good conduct on several occasions—it was a compliment well deserved. On the night of the 3d of May, the rebels kept up a tremendous fire during the whole night. Heavy explosions, not of artillery, were frequent, and it was evident that some move of importance was in progress. At an early hour the usual detail of sharp shooters relieved the infantry pickets in the advanced rifle pits, and soon after daylight it became apparent to them that matters at the front had undergone a change, and cautiously advancing from their lines they found the rebel works evacuated.

Pressing forward over the earth works which had so long barred the way, the sharp shooters were the first troops to occupy the village of Yorktown, where they hauled down the garrison flag which had been left flying by the retreating rebels. All was now joyous excitement; what was considered a great victory had been gained without any considerable loss of life—a consideration very grateful for the soldier to contemplate. Seventy-two heavy guns were abandoned by the rebels, which, though of little use to them, and of less to us, by reason of their antiquated styles, were still trophies, and so, valuable.

Regimental and brigade bands, which, together with drum and bugle corps, had been silent for a month, by general orders (for the rebels had kept up a tremendous fire on every thing they saw, heard or suspected), now filled the air with many a stirring and patriotic strain. Salutes were fired, and with the balloon, used for observing the movements of the enemy, floating in the air overhead, one could easily believe himself to be enjoying a festival, and for a moment forget the miseries of war. At Yorktown the rest of the regiment received their Sharpe's rifles and, with the exception of a few men who still clung to their muzzle loaders, the command was armed with rifles of uniform calibre, and which were entirely satisfactory to those who bore them. The Colt's five shooters were turned in without regret; for, although they had done fairly good service, they were not quite worthy of the men in whose hands they were placed.
