Earl Van Dorn and his 16,000-man Army of the West set out to counterattack the Union position near Pea Ridge.

Curtis's Army of the Southwest marched to meet the…READ MORE

Port Gibson, ten miles east of Bruinsburg on the Bayou Pierre River, commanded the best approach routes and was the first Federal objective. A Confederate force there was commanded by Maj. Gen. John S. Bowen. Grant's A…READ MORE

In mid-May, 1863, after six months of unsuccessful attempts, Maj. Gen. Ulysses S. Grant's Army of the Tennessee finally converged on Vicksburg, defended by a Confederate army under Lt. Gen. John C.

To clear the Shenandoah River valley of Confederates, Maj. Gen. Phil Sheridan moved on Winchester in mid-September 1864. Sheridan's force of over 39,000 men was more than twice the size of Maj. Gen. Jubal Early's Confederate army defending the valley. After Brig. Gen. Joseph Kershaw's division left Winchester to rejoin Robert E.
