To the Senate and House of Representatives:
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.
The several departments of the government at that time contained so large a number of disloyal persons that it would have been impossible to provide safely through official agents only for the performance of the duties thus confided to citizens favorably known for their ability, loyalty, and patriotism.
The several orders issued upon these occurrences were transmitted by private messengers, who pursued a circuitous way to the seaboard cities, inland across the States of Pennsylvania and Ohio and the northern lakes. I believe by these and other similar measures taken in that crisis, some of which were without any authority of law, the government was saved from overthrow. I am not aware that a dollar of the public funds thus confided without authority of law to unofficial persons was either lost or wasted, although apprehensions of such misdirection occurred to me as objections to those extraordinary proceedings, and were necessarily overruled.
I recall these transactions now because my attention has been directed to a resolution which was passed by the House of Representatives on the 30th day of last month, which is in these words:
"Resolved, That Simon Cameron, late Secretary of War by investing Alexander Cummings with the control of large sums of the public money and authority to purchase military supplies without restriction, without requiring from him any guaranty for the faithful performance of his duties, when the services of competent public officers were available, and by involving the government in a vast number of contracts with persons not legitimately engaged in the business pertaining to the subject-matter of such contracts, especially in the purchase of arms for future delivery, has adopted a policy highly injurious to the public service, and deserves the censure of the House."
Congress will see that I should be wanting equally in candor and in justice if I should leave the censure expressed in this resolution to rest exclusively or chiefly upon Mr. Cameron. The same sentiment is unanimously entertained by the heads of department who participated in the proceedings which the House of Representatives have censured. It is due to Mr. Cameron to say that although he fully approved the proceedings they were not moved nor suggested by himself, and that not only the President, but all the other heads of departments, were at least equally responsible with him for whatever error, wrong, or fault was committed in the premises.
