History of the Unit:
"In July, 1861, Joseph M. Knap, at that time serving as First Lieutenant of Company L, of the Twenty-eighth Regiment, Colonel John W. Geary, stationed at Point of Rocks, received authority to recruit a battery to serve with this regiment, which was near the proportions of a brigade, having eighteen full companies. He immediately proceeded to Pittsburg (PA) for recruits, and upon his arrival there, found a company which had been raised by Charles A. Atwell, and James D. M'Gill, intended for service in the Sixty-third Regiment, but which was offered to Captain Knap for his battery. It was promptly accepted, and at once proceeded to join the Twenty-eighth. Its ranks, however, were not full, and Colonel Geary applied for, and received permission of the War Department, to transfer surplus men of his command to the battery, in sufficient numbers to give it a maximum strength. It was then formally organized at Camp DeKorponay, Maryland, with the following officers:

- Joseph M. Knap, Captain
- Charles A. Atwell, First Lieutenant
- Clement Tingley, Jr., First Lieutenant
- Edward R. Geary, Second Lieutenant
- James D. M'Gill, Second Lieutenant."
