Unfortunately, shortly before dawn on May 12, Union forces comprising three full divisions (Major General Winfield S. Hancock's II Corps) attacked the Mule Shoe through heavy fog, taking the Confederate forces by surprise. Exhaustion, inadequate food, lack of artillery support, and wet powder from the night's rain contributed to the collapse of the Confederate position as the Union forces swarmed out of the mist, overwhelming Steuart's men and effectively putting an end to the Virginia Brigade. Confederate muskets would not fire due to damp powder, and apart from two remaining artillery pieces, the Southerners were effectively without firearms. During the thick of the fierce hand-to-hand fighting that followed, Steuart was forced to surrender to Colonel James A. Beaver of the 148th Pennsylvania Infantry. Beaver asked Steuart "Where is your sword, sir?", to which the general replied, with considerable sarcasm, "Well, suh, you all waked us up so early this mawnin' that I didn't have time to get it on." Steuart was brought to General Hancock, who had seen Steuart's wife Maria in Washington before the battle and wished to give her news of her husband. He extended his hand, asking "how are you, Steuart?" But Steuart refused to shake Hancock's hand; although the two men had been friends before the war, they were now enemies. Steuart said: "Considering the circumstance, General, I refuse to take your hand", to which Hancock is said to have replied, "And under any other circumstance, General, I would have refused to offer it." After this episode, an offended Hancock then left Steuart to march to the Union rear with the other prisoners.
