The Battle of Pea Ridge on March 6-8, 1862, was one of the few Civil War battles for which the Confederates mustered the larger force — 16,500 to 10,500.

Despite that, the CSA lost the battle and suffered 2,000 casualties to the North’s 1,384.

It left Missouri and northern Arkansas in federal control.

The battlefield at Pea Ridge is now Pea Ridge National Military Park, one of the best preserved Civil War battlefields.
