But if, as now appears to be true, in pursuit of a purpose to drive the United States authority from these places, an unprovoked assault has been made upon Fort Sumter, I shall hold myself at liberty to repossess, if I can, like places which had been seized before the Government was devolved upon me.  And in every event I shall, to the extent of my ability, repel force by force.  In case it proves true that Fort Sumter has been assaulted, as is reported, I shall perhaps cause the United States mails to be withdrawn from all the States which claim to have seceded, believing that the commencement of actual war against the Government justifies and possibly demands this.

I scarcely need to say that I consider the military posts and property situated within the States which claim to have seceded as yet belonging to the Government of the United States as much as they did before the supposed secession.

Whatever else I may do for the purpose, I shall not attempt to collect the duties and imposts by any armed invasion of any part of the country; not meaning by this, however, that I may not land a force deemed necessary to relieve a fort upon a border of the country.

From the fact that I have quoted a part of the inaugural address, it must not be inferred that I repudiate any other part, the whole of which I reaffirm, except so far as what I now say of the mails may be regarded as a modification.

PROCLAMATION CALLING FOR 75,000 MILITIA, AND CONVENING CONGRESS IN EXTRA SESSION, APRIL 15, 1861.

By the president of the united states of America: 

A Proclamation.

Whereas the laws of the United States have been for some time past and now are opposed, and the execution thereof obstructed, in the States of South Carolina, Georgia, Alabama, Florida, Mississippi, Louisiana, and Texas, by combinations too powerful to be suppressed by the ordinary course of judicial proceedings, or by the powers vested in the marshals bylaw: 

Now, therefore, I, Abraham Lincoln, President of the United States, in virtue of the power in me vested by the Constitution and the laws, have thought fit to call forth, and hereby do call forth, the militia of the several States of the Union, to the aggregate number of seventy-five thousand, in order to suppress said combinations, and to cause the laws to be duly executed.

The details for this object will be immediately communicated to the State authorities through the War Department.

I appeal to all loyal citizens to favor, facilitate, and aid this effort to maintain the honor, the integrity, and the existence of our National Union, and the perpetuity of popular government; and to redress wrongs already long enough endured.

I deem it proper to say that the first service assigned to the forces hereby called forth will probably be to repossess the forts, places, and property which have been seized from the Union; and in every event the utmost care will be observed, consistently with the objects aforesaid, to avoid any devastation, any destruction of or interference with property, or any disturbance of peaceful citizens in any part of the country.
