Trapped inside the armory enginehouse, the raiders and their hostages await the attack by U.S. Marines under Col. Robert E. Lee.

By 7 a.m. there was enough light for operations. All arrangements for the assault had been completed. The militia formed up outside the armory wall to keep the street clear of spectators and to prevent indiscriminate firing that might injure the storming party. The Marines took position at the northwest corner of the enginehouse, just out of the line of fire from the door. Then Lieutenant Stuart moved forward with the surrender demand. Brown opened the door a few inches and placed his body against the crack so the lieutenant could not see inside. He held a cocked rifle in one hand. Stuart read the terms offered by Lee:

Colonel Lee, United States Army, commanding troops sent by the President of the United States to suppress the insurrection at this place, demands the surrender of the persons in the Armory buildings. If they will peaceably surrender themselves and restore the pillaged property, they shall be kept in safety to await the orders of the President. Col. Lee represents to them, in all frankness, that it is impossible for them to escape; that the Armory is surrounded on all sides by troops; and that if he is compelled to take them by force he cannot answer for their safety.

Robert E. Lee and J. E. B. Stuart are pictured here about the time of the raid.

This little-known portrait of Stuart shows him in civilian dress and with trimmed beard.

According to Stuart, the parley was “a long one.” Brown refused to surrender. Instead he presented his own propositions “in every possible shape, and with admirable tact,” insisting that he, his men, and his hostages be permitted to cross the river unmolested.

Stuart, instructed not to accept any counter-proposals, sensed that further discussion was useless. Stepping back from the door, he waved his hat, a pre-arranged signal for the Marines to attack. Brown slammed the door shut and the troops came on. Three men with sledge hammers pounded the center door of the enginehouse, but it would not yield; the raiders had placed the fire engines against it. Spotting a heavy ladder nearby, Lieutenant Green directed his men to use it as a battering-ram. On the second blow the door splintered and a small opening was effected.
