Commanded by Brigadier General J. C. Robinson

The 2nd Division suffered 56% casualties at Gettysburg, most in fighting west of town on the first day. Gabriel Paul’s First Brigade fared slightly worse with 67%, with Paul suffering a head wound that left him blind. The loss of officers in his brigade was so severe that the 11th Pennsylvania was temporarily transferred from the Second Brigade so that Colonel Richard Coulter could take command; when he, in turn, was wounded, Colonel Peter Lyle of the 90th Pennsylvania was borrowed to take over the survivors.
