But the expedient was one of desperation.

By this movement Brown literally shut himself up in his own prison, from which escape was impossible.
A desultory fire was kept up through doors and loop-holes.

But now the whole country had become thoroughly aroused, and sundry military companies from neighboring towns and counties poured into Harper's Ferry.

Brown himself at length realized the hopelessness of his position, and parleyed for leave to retreat across the river on condition of his giving up his prisoners; but it was too late.
President Buchanan also took prompt measures; and on Monday night a detachment of eighty marines from the Washington navy-yard, under command of Brevet Colonel Robert E.Lee, of the United States army, the same who afterwards became the principal leader of the Confederate armies in the rebellion, reached the scene of action, and were stationed in the armory yard so as to cut off the insurgents from all retreat.

At daylight on Tuesday morning Brown was summoned to surrender at discretion, but he refused.
