At Allstadt’s, Gibson divided his force. He sent Mexican War veteran Capt. J. W. Rowan with the Jefferson Guards in a wide sweep to the west of Harpers Ferry to capture the B & O bridge. Gibson himself would take the volunteer company on into town. Rowan’s men crossed the Potomac about a mile above Harpers Ferry and, advancing along the towpath of the Chesapeake and Ohio Canal, arrived at the Maryland end of the bridge by noon. With little difficulty they drove its defenders—Oliver Brown, William Thompson, and Dangerfield Newby—back toward the armory yard. Only Brown and Thompson made it. Newby, the ex-slave who had joined John Brown to free his wife and children, was killed by a 6-inch spike fired from a smoothbore musket. He was the first of the raiders to die. In the meantime, Colonel Gibson’s force had arrived in Harpers Ferry and he sent a detachment of citizens under Capt. Lawson Botts, a Charles Town attorney, to secure the Gault House Saloon at the rear of the arsenal and commanding the Shenandoah bridge and the entrance to the armory yard. Another detachment under Capt. John Avis, the Charles Town jailer, took up positions in houses along Shenandoah Street from which to fire into the arsenal grounds. The attack of the Charles Town militia cut off Brown’s escape route and separated him from his men in Maryland and those still holding the rifle factory. At last, perhaps realizing the hopelessness of his situation, Brown sought a truce. But when hostage Rezin Cross and raider William Thompson emerged from the enginehouse under a white flag, the townspeople ignored the flag, seized Thompson, and dragged him off to the Wager House where he was kept under guard. Still not convinced, Brown tried again. This time he sent his son Watson and Aaron Stevens with Acting Armory Superintendent Kitzmiller, taken hostage earlier in the day. As the trio marched onto the street and came opposite the Galt House, several shots rang out and both raiders fell. Stevens, severely wounded, lay bleeding in the street; Watson Brown, mortally wounded, dragged himself back to the enginehouse. Joseph Brua, one of the hostages, volunteered to aid the wounded Stevens. As bullets richocheted off the flagstone walk, Brua walked out, lifted up the wounded raider, and carried him to the Wager House for medical attention. Then, incredibly, he strolled back to the enginehouse and again took his place among Brown’s prisoners. Kitzmiller escaped.
