Oct. 1, J. Henry Sleeper, the newly appointed Captain of the Company, arrived. He had been pronoted to this position from a first lieutenancy in the First Massachusetts Battery.

Capt. Jacob Henry Sleeper was a Bostonian by birth, son of the Hon. Jacob Sleeper of the Governor's Council. He was twenty-three years of age and entered the army at the beginning of the war as 1st Lieutenant in the Fifth Massachusetts Infantry, where he won praise from his superiors for coolness and bravery in the first battle of Bull Run.
