Twelfth Army Corps

On September 17, 1862, Stainrook's Brigade of Green's Division, Twelfth Army Corps, commanded by Col. Henry J. Stainrook and composed of the 3d Maryland Infantry, 102d New York Infantry, and 111th Pennsylvania Infantry, advanced after the Confederate right flank had been turned, pursued through the East Woods, crossed the fields to the left of the burned buildings on the Mumma Farm, and halted behind the ridge a few yards east of this point, where with the assistance of Monroe's and Tomkin's Rhode Island Batteries it protected the right of French's Division of the Second Corps and repulsed several assaults of the enemy. About 10:30 a.m., the brigade crossed this road and entered the woods on the left of the Dunkard Church, with its left on the road directly opposite this point, where it remained until noon, when it was compelled to retire to the East Woods.
