They were placed under the command of Major Lionel F Booth on March 18th 1864.
The 6th were sent to Fort Pillow. The fort was attacked on April 12th 1864 by about 3,000 Confederate troops. Booth was shot by a sniper and killed early in the fighting. Command of the 6th fell to Captain Charles Epeneter who was also wounded. The 6th’s guns weren’t effective as the Confederates stormed the fort as the guns couldn’t be depressed enough to fire on them.
Following the Battle of Fort Pillow, those members of the 6th who survived were moved into the 11th United States Colored Troops.
