No. 13. Report of Lieutenant James Stewart, Battery B, Fourth U. S. Artillery, of the battle of Antietam.

CAMP NEAR SHARPSBURG, MD.,

September 24, 1862.

SIR: I have the honor to submit the following report of the operations of Light Company B, Fourth U. S. Artillery, during the engagement of the 17th instant:

I was ordered by General Gibbon to bring my section forward and place it in position, about 75 yards distant from and to the left of the turnpike, for the purpose of shelling the woods, distant from 800 to 900 yards, directly in my front.

After shelling for some time, General Gibbon ordered the section to be still farther advanced to a position in front of some straw-stacks, about 30 yards to the right of the turnpike. As soon as I came into battery in this position, I observed large bodies of the enemy from 400 to 500 yards distant, and ordered their guns to be loaded with spherical case, 1 1/2 and 1 1/2 seconds, because the ground was undulating, and not suitable for canister. After firing two or three rounds from each gun, the enemy partially broke, ran across a hollow in front of the section, crossed to the left of the turnpike, entered a corn-field, and, under cover of the fences and corn, crept close to our guns, picking off our cannoneers so rapidly that in less than ten minutes there were 14 men killed and wounded in the section.

About this time Captain Campbell, commanding the battery, brought the other four guns into battery on the left of my section, and commenced firing canister at the enemy in the corn-field, on the left of the turnpike. On less than twenty minutes Captain Campbell was severely wounded in the shoulder, his horse shot in several places, and the command of the battery devolved upon me.

General Gibbon was in the battery, and, seeing the advantage which the enemy had, ordered one of the guns which was placed on the turnpike to be used against the enemy's infantry in the corn-field, General Gibbon acting both as cannoneer and gunner at this piece. The fire was continued by the entire battery for about ten minutes longer in this position, the enemy part of the time being but 15 or 20 yards distant. The loss of the entire company whilst in this position was 1 captain wounded, 3 sergeants, 4 corporals, 32 privates killed and wounded, and 26 horses killed and 7 wounded. While in this position the battery was supported by General Gibbon's brigade and a part of the Twentieth New York Volunteers.

General Gibbon ordered me to limber to the rear and place the battery in battery in the same position me section first occupied in the morning. Here I found Captain Ransom's battery, of the Fifth Artillery, in position,
