_And whereas_, An Executive Proclamation has already been issued, requiring the persons engaged in these disorderly proceedings to desist therefrom, calling out a militia force for the purpose of repressing the same, and convening Congress in extraordinary session to deliberate and determine thereon: Now, therefore, I, ABRAHAM LINCOLN, President of the United States, with a view to the same purposes before mentioned, and to the protection of the public peace, and the lives and property of quiet and orderly citizens pursuing their lawful occupations, until Congress shall have assembled and deliberated on the said unlawful proceedings, or until the same shall have ceased, have further deemed it advisable to set on foot a blockade of the ports within the States aforesaid, in pursuance of the laws of the United States, and of the laws of nations in such cases provided. For this purpose a competent force will be posted so as to prevent entrance and exit of vessels from the ports aforesaid. If, therefore, with a view to violate such blockade, a vessel shall approach or shall attempt to leave any of the said ports, she shall be duly warned by the commander of one of the blockading vessels, who shall indorse on her register the fact and date of such warning; and if the same vessel shall again attempt to enter or leave the blockaded port, she will be captured and sent to the nearest convenient port, for such proceedings against her and her cargo, as prize, as may be deemed advisable. And I hereby proclaim and declare, that if any person, under the pretended authority of said States, or under any other pretense, shall molest a vessel of the United States, or the persons or cargo on board of her, such person will be held amenable to the laws of the United States for the prevention and punishment of piracy. _By the President_, ABRAHAM LINCOLN. WILLIAM H. SEWARD, Secretary of State. WASHINGTON, April 19, 1861. On the 27th of April the President issued a proclamation by which the blockade of Southern ports was extended to the ports of North Carolina and Virginia. And on the 16th of May, by another proclamation, the President directed the commander of the United States forces in Florida to "permit no person to exercise any office or authority upon the islands of Key West, Tortugas, and Santa Rosa, which may be inconsistent with the laws and Constitution of the United States; authorizing him, at the same time, if he shall find it necessary, to suspend the writ of _habeas corpus_, and to remove from the vicinity of the United States fortresses all dangerous and suspected persons."
