11:00 a.m.-3:00 p.m. July 9, 1864
Confederate troops succeeded in finding their way across the Monocacy River at the foot of this hill. Brig. Gen. John McCausland’s 350 cavalrymen came up over the hill and assembled on the front yard of the Worthington farm. Maj. Gen. John B. Gordon’s 3,000 infantrymen crossed about three hours later, swung south of the house, and proceeded over Brooks Hill to your left. The next goal of the Confederates: to maneuver around the Federals’ left line on the neighboring Thomas farm.
