The 78th Pennsylvania Volunteer Infantry Company F was recruited in Freeport, Armstrong County, by Dr. Charles B. Gillespie and others. This company was composed of mechanics, farmers, laborers, miners and teachers. The date of enlistment is given as September 10th, but the company came to Camp Orr September 3rd, with 24 men.

       At the end of the regiments initial enlistment the recruits whose time had not expired and veteran volunteers remained at Nashville under the command of Major Bonnaffon and Lieutenants Torbett and Smith. They were organized into two companies and afterwards became companies A and B at the new organization of the Regiment. Sergeant Rankin of Company A was promoted to 2nd Lieutenant of Company A, December 3, 1864. William B. McCue was promoted from Sergeant to 1st Lieutenant, December 2, 1864. Lieutenant Smith of Company K was promoted to Captain of Company B, December 3, 1864. Sergeant Andrew Brown was promoted from Sergeant to 1st Lieutenant of Company B, December 3, 1864. Bernad Keigan was promoted from Sergeant to 2nd Lieutenant of Company B, December 4, 1864.

       The two companies of veterans and recruits were organized in this way until February of 1865, when the Governor of Pennsylvania assigned eight new companies to the organization, upping them to the minimum regimental strength. When this organization took place Major Bonnaffon was commissioned as Colonel of the Regiment, Henry W. Torbett as Lieutenant Colonel, Robert M. Smith as Major, the other commissioned officers being advanced in rank so that David A. Rankin became Captain of Company A, and Andrew Brown, Captain of Company B.
        By the time the 78th Regiment had completed its second organization General Hood's Army had been driven from Tennessee, and the new Regiment did not have any opportunity for engaging in any great battle, but, under the leadership of that brave and brilliant veteran, Colonel Bonnaffon, the Regiment performed its duty faithfully until the close of the War, and was mustered out of the service, September 11, 1865 at Harrisburg, Pennsylvania.
