The 4th Regiment of the Ohio Volunteer Infantry was composed of companies from Wayne, Stark, Knox, Delaware, Marion, and Hardin Counties in Ohio. They were raised in the week following President Lincoln’s Proclamation asking for 75,000 men to serve three months. Lorin Andrews was reportedly the first to volunteer for the war, sending a letter to Governor Dennison before the Fall of Sumter on 14 April 1861. While he enlisted as a private, he was chosen as colonel, and in the same month soldiers were organized under at Camp Jackson in Columbus, Ohio under his command to form a unit for three months service as Lincoln had called for. However, on 5 June 1861, many of these soldiers were reorganized at Camp Dennison in Hamilton, Ohio. These 1004 soldiers would reenlist for a three year term ending on 21 June 1864. They spent most of their time as a unit in West Virginia and Virginia with a few additional battles in Maryland and Pennsylvania. They served in the Army of the Potomac and helped to ease the draft riot in New York. When Colonel Andrews died during the war of camp fever, John S. Mason took charge of the command of the regiment. At the time when their three years ended, some soldiers of this unit were merged with the 8th Regiment of the Ohio Volunteer Infantry and formed the 4th Battalion Ohio Infantry.
Company C was among the 4th Regiment and it was under the command of Captain James M. Crawford. The company was composed mostly of soldiers from Delaware County, Ohio and was known as the, ‘Delaware Guards’. They were organized on the evening of the 16th of April in the Templar Hall in Delaware. These soldiers were assigned to the left flank, and adopted a battle technique known as the Zouave drill. The unit was given Enfield rifles to use.
