During the following Seven Days Battles, after fighting in the Battle of Gaines Mill, Sanders was severely wounded in the leg by a shell fragment at the Battle of Glendale, June 30, 1862, in Henrico County, Virginia. Nonetheless, he returned to command the regiment on August 11, 1862 as he was the senior officer on duty. He was wounded again at the Battle of Second Bull Run on August 30, 1862. Sanders was formally promoted to colonel after the Battle of Antietam, September 17, 1862, where his face was wounded by stones thrown up by an exploding shell. Sanders fought at the Battle of Fredericksburg, Battle of Salem Church, and Battle of Gettysburg, where he was wounded in the knee on July 2, 1863.

As part of Major GeneralWilliam Mahone's division, Sanders's brigade participated in the defense of the Confederate line during the Battle of the Crater, July 30, 1864, where he led his brigade in the Confederate counterattack. Brigadier General Sanders was killed in action in an engagement along the Weldon Railroad in Virginia which is generally known as Battle of Globe Tavern, on August 21, 1864 when he was shot through both thighs and bled to death within a few minutes.
