On this day in 1862, Union forces under General Samuel Curtis clash with the army of General Earl Van Dorn at the Battle of Pea Ridge (also called the Battle of Elkhorn Tavern),in northwest Arkansas. The following day, the battle endedin defeat for the Confederates.
Pea Ridge was part of a larger campaign for control of Missouri. Seven months earlier, the Confederates defeated a Union force at Wilson’s Creek, some 70 miles northeast of Pea Ridge. General Henry Halleck, the Federal commander in Missouri, now organized an expedition to drive the Confederates from southwestern Missouri. In February 1862, Yankee General Samuel Curtis led the 12,000-man army toward Springfield, Missouri. Confederate General Sterling Price retreated from the city with 8,000 troops in the face of the Union advance. Price withdrew into Arkansas, and Curtis followed him.
Price hooked up with another Rebel force led by General Ben McCulloch, and their combined army was placed under the leadership of General Earl Van Dorn, recently appointed commander of Confederates forces in the trans-Mississippi area. Van Dorn joined Price and McCulloch on March 2, 1862,and ordered an advance on Curtis’ army. Curtis received word of the approaching Confederates and concentrated his force around Elkhorn Tavern. Van Dorn sent part of his army on a march around the Yankees. On March 7, McCulloch slammed into the rear of the Union force, but Curtis anticipated the move and turned his men towards the attack. McCulloch was killed during the battle, and the Confederate attack withered. Meanwhile, the other part of Van Dorn’s army attacked the front of Curtis’ command. Through bitter fighting the Union troops held their ground.
Curtis, suspecting that the Confederates were low on ammunition, attacked the divided Rebel army the following morning. Van Dorn realized he was in danger and ordered a retreat, ending the battle. The Yankees suffered some 1,380 men killed, wounded, or captured out of 10,000 engaged; the Confederates suffered a loss of about 2,000 out of 14,000 engaged. The Union won a decisive victory that also helped them clear the upper Mississippi Valley region on the way to securing control of the Mississippi River by mid-1863.
