A grieving Garland saw action in July at First Bull Run. He gained a reputation for fearlessness under fire, which some believed stemmed from a death wish. He also saw action at Dranesville, Battle of Oak Grove, Battle of Beaver Dam Creek, Battle of Seven Pines, Battle of Gaines' Mill, Battle of Malvern Hill, and Williamsburg, having been wounded at the latter by a ball in the elbow on May 5, 1862. For bravery in battles and commanding skills, on May 23, 1862 Garland was promoted to Brigadier General. After promotion, Garland distinguished himself in the Peninsula Campaign (March–July 1862) and the Seven Days Battles (June 25-July 1, 1862).
