Wade's Battery (later Walsh's Battery, also known as the 1st Light Battery) was an artillery battery in the Confederate States Army during the American Civil War. The battery was mustered into Confederate service on December 28, 1861; many of the members of the battery had previously served in the Missouri State Guard. Assigned to the First Missouri Brigade, the battery saw action at the Battle of Pea Ridge and the Second Battle of Corinth in 1862. In 1863, the battery fought at the Battle of Grand Gulf, where Captain William Wade, first commander of the battery, was killed. The battery later saw action at the Battle of Champion Hill, Battle of Big Black River Bridge, and the Siege of Vicksburg. When the Confederates surrendered at the end of the Siege of Vicksburg, the men of the battery became prisoners of war. After a prisoner exchange, the men of the battery were combined with Landis's Battery and Guibor's Battery on October 3, 1863, and Wade's Battery ceased to exist as a separate unit.
