By the spring of 1862, Union forces had pushed Confederates south and west through Missouri into northwestern Arkansas. On the night of March 6, 1862, Confederate Maj. Gen. Earl Van Dorn and his 16,000-man Army of the West set out to counterattack the Union position near Pea Ridge. Hoping to move quickly, in a fateful decision, Van Dorn ordered the supply trains far to the rear. Learning of Van Dorn's approach, some 10,000 Federals in Brig. Gen. Samuel R.

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. Pemberton. Capture of the Mississippi River town was critical to Union control of the strategic river. Vicksburg was located on a high river bluff defended with artillery, and Pemberton's men had constructed a series of fortifications in an 8-mile arc surrounding the city on the landward side.

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. Lee's army at Petersburg, Early renewed his raids on the Baltimore and Ohio Railroad at Martinsburg in the lower valley, dispersing his four remaining infantry divisions. On Septem…READ MORE
