The 77th Illinois Volunteer Infantry Regiment, Companies C, F and H, also had a substantial Woodford County contingent. Serving under Maj. Gen. Gordon Granger, they participated in the initial phase of the Vicksburg Campaign. The 77th then participated in the Battle of Jackson, Mississippi (May 1863), and taking the city. Disaster struck in April 1864 near Alexandria, Louisiana, when the unit was isolated and crushed in a cavalry support operation at the Battle of Sabine Cross-roads. 176 men of the 77th Illinois were killed, wounded, or captured, leaving only 125 members of the regiment fit for duty. The unit was mustered out in July 1865, having participated in 16 battles.
