Later, York's consolidated brigade of Tigers fought in Early's army during the Battle of Monocacy and several subsequent battles in the Shenandoah Valley. In late 1864, the Tigers returned to the Army of Northern Virginia in the trenches around Petersburg, Virginia. By the Appomattox Campaign, many regiments were reduced to less than 100 men apiece, and Brig. Gen. William R. Peck had become the Tigers' final commander.
