In 1863 it became necessary to recruit a class of troops whose duty it should be to fortify, garrison, and hold many important forts and strongholds that had been captured from the enemy. For this purpose the Second Ohio Heavy Artillery, consisting of twenty-four hundred men, rank and file, was then authorized.

Company M, commanded by Captain William H.H. Crowell, and other companies of the regiment were largely recruited from Ashtabula and Lake counties. Company M was mustered into service September 9, 1863, at Covington Barracks, and on the 18th of the same month it moved to Fort Willich, Mumfordsville, Kentucky. January 10, 1864, it was transferred to Fort Taylor,at Camp Nelson, Kentucky, where it remained on duty until May 26, 1864. From Camp Sedgwick, at Cleveland, Tennessee, it participated with the rest of the regiment in various expeditions, and was engaged in a skirmish at Strawberry Plains, where the Union forces were in a critical position. February 1, 1865, it was at Athens, Tennessee. It was there mustered out of the service, August 23, 1865, and on the 29th of the same month was paid and disbanded at Camp Chase, Ohio.
