Battle of Iuka: Prelude to the Battle of Corinth
Northern Mississippi was the scene of much maneuvering during the summer of 1862. The Confederates were forced to evacuate Corinth in May in the face of heavy Union pressure, but they maintained two armies in the area. On September 19, one of these armies, commanded by Earl Van Dorn, was defeated by Union troops under William Rosecrans at the Battle of Iuka, 20 miles east of Corinth. Shortly after, Van Dorn combined his force with that of Sterling Price to form a 22,000-man army that turned toward Corinth to launch anotherattack against Rosecrans, who had consolidated his forces there.
Battle of Corinth: October 3-4, 1862
Van Dorn hurled his army at the outer defenses of Corinth on the morning of October 3. Over the course of the spring and summer, both Union and Confederate occupiers of Corinth had constructed concentric rings of trenches around the city. The Confederates were initially successful at capturing the outer defenses, driving the 23,000 defenders back nearly two miles. The battle lasted all day, and only nightfall brought relief to the battered Yankees.
The next day, the Confederates made a series of desperate assaults on the inner trenches. They suffered heavy losses and began to withdraw from Corinth by early afternoon. The Confederate defeat was devastating. The Union losses included more than 2,300 dead, wounded or captured, while the Confederates suffered more than 4,200 casualties. The Confederate defeat at Corinth allowed the Union to focus attention on capturing Vicksburg, Mississippi, the last major Rebel stronghold on the Mississippi River.
