Greene's Division, Twelfth Army Corps,
Brig. Gen. Geo. S. Greene, Commanding,
(September 17, 1862.)
Tyndale's and Stainrook's Brigades of Greene's Division formed line about 8 a.m., a short distance beyond the East Woods and, advancing to their eastern edge, struck the right of the Confederate line at and north of this point, turned it after a short and sharp contest and compelled the Confederate forces north of the Smoketown Road and east of the Hagerstown Pike to withdraw to the West Woods and the fields south of the Smoketown Road. Moving obliquely to the left the two brigades - Tyndale on the right and Stainrook on the left - crossed the Smoketown Road and followed in pursuit to the ridge on Mumma's Farm east of the Dunkard Church.
