In fact, it comprised two regiments — one in the Ninth, and one in the Eighteenth Corps. In the spring of 1864, the regiment, 1800 strong, joined the Second Division of the Eighteenth Corps, at Cold Harbor. The surplus men had been previously formed into a "provisional" regiment with the same designation, and assigned to the Ninth Corps. The most of the losses occurred in this provisional command.
