President Lincoln, his wife Mary, and some officers rode out to observe the attack, either on July 11 or July 12, and were briefly under enemy fire that wounded a Union surgeon standing next to Lincoln on the Fort Stevens parapet. Lincoln was brusquely ordered to take cover by an officer, possibly Horatio Wright, although other probably apocryphal stories claim that it was Oliver Wendell Holmes, Jr., Private John A. Bedient of the 150th Ohio Infantry, the fort commander, other privates of the Ohio National Guard, and Elizabeth Thomas.
