Other militia units now began to arrive. Between 3 and 4 p.m. the Hamtramck Guards and the Shepherdstown Troop, both from Shepherdstown, Va., came in. At dusk three uniformed companies from Frederick, Md., appeared, followed later in the evening by a Winchester, Va., company under R. B. Washington, and five companies of the Maryland Volunteers under General Stewart from Baltimore. None of them made any attempt to dislodge Brown and his men from the enginehouse, but all added to the general confusion and hysteria gripping the town. [Illustration: The attack on the enginehouse by Baltimore and Ohio Railroad employees led by Capt. E. G. Alburtis is shown in this contemporary engraving from _Frank Leslie’s Illustrated Newspaper_. Alburtis’ attack failed to dislodge the raiders, but his men did manage to free several of Brown’s hostages.] On the other side of the Potomac, Cook, Owen Brown, Barclay Coppoc, Meriam, Tidd, and several Negroes had been transferring weapons to a tiny schoolhouse midway between Harpers Ferry and the Kennedy farm. As the day wore on and the firing from town became heavier, they began to suspect that something might have gone wrong. At about 4 p.m. Cook headed for the B & O bridge to see what was happening. To get a better vantage point, he climbed the craggy face of Maryland Heights where he could look directly into the center of the town. Seeing that his compatriots were “completely surrounded,” he decided to try to take some of the pressure off by firing across the river at men posted in the houses along High Street overlooking the armory. His shot was instantly answered by a volley of bullets that severed a branch he was clutching for support and sent him tumbling down the rocky cliff. Badly cut and bruised from the fall, he limped back to the schoolhouse and joined the others. Realizing there was nothing they could do to aid their comrades trapped in the enginehouse, they reluctantly gathered their belongings, climbed the mountain and headed north. [Illustration: Stewart Taylor] [Illustration: John A. Copeland] [Illustration: Jeremiah G. Anderson] Time was quickly running out for John Brown. As resistance became partially organized at Harpers Ferry, steps were taken to seal off any possibility of support reaching the raiders. Fearing that Brown’s raid might be part of a general uprising, all approaches to the town were guarded, and all travelers not familiar to residents of the area were immediately arrested and shipped off to the county jail at Charles Town.
