After the Confederate right flank had been turned, Stainrook’s Brigade pursued through the East Woods, crossed the fields to the left of the burned out buildings of the Mumma farm, and halted behind the ridge a few yards east of this point where with the assistance of Monroe’s and Tompkins’ 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, its left on the road directly opposite this tablet where it remained until noon when it was compelled to retire to the East Woods.
