from the neighborhood, arming themselves, immediately returned the fire of the assailants with such effect that in the course of a few hours they were driven from their positions, and all either killed or wounded, with the exception of the leader and half a dozen others of his party, who were driven into an engine-house, whither they fled for security. They carried along with them ten or twelve of the prisoners they had taken the night before, who were to be used as hostages, as the robbers alleged, to prevent the fire of the citizens outside from being directed towards themselves in the house where they had taken shelter.
Throughout the whole day on Monday, from twelve o'clock, at which time intelligence of the outbreak reached this city, the most exaggerated accounts were received of the state of things at Harper's Ferry, and the number of persons engaged in it. Prompt measures, however, were taken, and Brevet Colonel Robert E. Lee, of the First Cavalry, was at once summoned to take command of a detachment of marines and two companies of volunteers from Frederick, Maryland, who had promptly offered their services. The troops left this city by the afternoon train, and, taking up the volunteers on the way, reached the scene of action during the night.
The next morning, at an early hour. Colonel Lee gave orders to the marines to attack and carry the house where the conspirators were strongly barricaded, which was very promptly and gallantly done, with the loss of one man killed, another- wounded. Colonel Lee's report of his proceedings is herewith communicated, which gives all other information on the subject thought to be of interest.
I have the honor to be, very respectfully, your obedient servant,
JOHN B. FLOYD,
Secretary of War.
The President.
