The Battle of Gettysburg (July 1–3, 1863) was to prove a turning point in the war, and the end of Lee's advance. Steuart's men arrived at Gettysburg "exhausted and footsore...a little before dusk" on the evening of July 1, following a march from Sharpsburg, "many of them barefooted". Steuart's men attacked the Union line on the night of July 2, gaining ground between the lower Culp's Hill and the stone wall near Spangler's Spring. But fresh Federal reinforcements blocked his further advance, and no further ground was gained. During the night a large number quantity of Union artillery was wheeled into place, the sound of which caused the optimistic Steuart to hope that the enemy was retreating in its wagons.
