The insurrection which is yet existing in the United States and aims at the overthrow of the Federal Constitution and the Union, was clandestinely prepared during the Winter of 1860 and 1861, and assumed an open organization in the form of a treasonable provisional government at Montgomery, in Alabama on the 18th day of February, 1861.  On the 12th day of April, 1861, the insurgents committed the flagrant act of civil war by the bombardment and the capture of Fort Sumter, Which cut off the hope of immediate conciliation.  Immediately afterward all the roads and avenues to this city were obstructed, and the capital was put into the condition of a siege.  The mails in every direction were stopped and the lines of telegraph cut off by the insurgents, and military and naval forces which had been called out by the government for the defense of Washington were prevented from reaching the city by organized and combined treasonable resistance in the State of Maryland.  There was no adequate and effective organization for the public defense.  Congress had indefinitely adjourned.  There was no time to convene them.  It became necessary for me to choose whether, using only the existing means, agencies, and processes which Congress had provided, I should let the government fall at once into ruin or whether, availing myself of the broader powers conferred by the Constitution in cases of insurrection, I would make an effort to save it, with all its blessings, for the present age and for posterity.

I thereupon summoned my constitutional advisers, the heads of all the departments, to meet on Sunday, the 20th day of April, 1861, at the office of the Navy Department, and then and there, with their unanimous concurrence, I directed that an armed revenue cutter should proceed to sea to afford protection to the commercial marine, and especially the California treasure ships then on their way to this coast.  I also directed the commandant of the navy-yard at Boston to purchase or charter and arm as quickly as possible five steamships for purposes of public defense.  I directed the commandant of the navy-yard at Philadelphia to purchase or charter and arm an equal number for the same purpose.  I directed the commandant at New York to purchase or charter and arm an equal number.  I directed Commander Gillis to purchase or charter and arm and put to sea two other vessels.  Similar directions were given to Commodore Dupont, with a view to the opening of passages by water to and from the capital.  I directed the several officers to take the advice and obtain the aid and efficient services, in the matter, of his Excellency Edwin D. Morgan, the Governor of New York, or in his absence George D. Morgan, William M. Evarts, R. M. Blatchford, and Moses H. Grinnell, who were by my directions especially empowered by the Secretary of the Navy to act for his department in that crisis in matters pertaining to the forwarding of troops and supplies for the public defense.
