HEADQUARTERS 145TH PENNSYLVANIA VOLUNTEERS, September 28, 1864.

ADJUTANT: I have the honor to submit the following report of operations of the regiment under my command during the engagement of the Second Corps, at Deep Bottom, from the 26th to the 30th of July, inclusive:

About noon of the 26th I received orders though brigade headquarters to have my command in readiness to move at 3.30 p. m. At the time designated the regiment formed in line with the division, moved on the City Point [road] some distance, then bore off to the left and crossed the Appomattox River, and camped about 3 a. m. of the 27th on the north bank. At daylight, with the brigade, formed line of battle and advanced, supporting the skirmish line during the day. In the evening two commissioned officers, with most of the regiment, went on picket. The remainder of the men were then moved back to protect the flank, and bivouacked for the night.

On the 28th were on support until evening, when we moved to the left and threw up a line of works during the night. On the 29th completed the works begun, arranged and cleared up camp during the day, and at 8 p. m. received orders to pack up, and a few moments after moved. Marched very hard during the remainder of the night, many of the troops giving out by the way, and arrived in front of Petersburg between daybreak and sunrise of the 30th, and lay on support of the lines, which were heavily engaged with the enemy. Here we remained during the day under cover of a hill, where it was very hot and unpleasant, until dark; wee ordered back to the camp left on the 26th - all without the loss of a man.

Captain, Commanding.
