During the prelude to war, a hastily created 86-man Marine detachment under Lieutenant Israel Greene was detached to arrest John Brown at Harper's Ferry in 1859, after the abolitionist raided the armory there. Command of the mission was given to then-Colonel Robert E. Lee and his aide, Lieutenant J.E.B. Stuart, both having been on leave in Washington when President James Buchanan ordered Brown arrested. The ninety Marines arrived to the town on 17 October via train, and quickly surrounded John Brown's Fort. Upon his refusal to surrender, the Marines stormed the building with bayonets, battering down the door with hammers and a ladder used as a battering ram. Greene slashed Brown twice and would have killed him had his sword not bent on his last thrust; in his haste he had carried his light dress sword instead of his regulation sword.
