You are aware of the great anxiety of the Secretary of War, that a collision of the troops with the people of the State shall be avoided, and of his studied determination to pursue a course with reference to the military force and forts in this harbor, which shall guard against such a collision. He has, therefore, carefully abstained from increasing the force at this point, or taking any measures which might add to the present excited state of the public mind, or which would throw any doubt on the confidence he feels that South Carolina will not attempt by violence to obtain possession of the public works, or interfere with their occupancy. But as the counsel and acts of rash and impulsive persons may possibly disappoint these expectations of the Government, he deems it proper that you shall be prepared with instructions to meet so unhappy a contingency. He has, therefore, directed me verbally to give you such instructions. You are carefully to avoid every act which would needlessly tend to provoke aggression, and for that reason you are not, without evident and imminent necessity, to take up any position which could be construed into the assumption of a hostile attitude, but you are to hold possession of the forts in this harbor, and if attacked you are to defend yourself to the last extremity. The smallness of your force will not permit you, perhaps, to occupy more than one of the three forts, but an attack on or an attempt to take possession of either one of them will be regarded as an act of hostility, and you may then put your command into either of them which you may deem most proper to increase its power of resistance. You are also authorized to take similar defensive steps whenever you have tangible evidence of a design to proceed to a hostile act.

The President, when the text of the instructions reached him, directed the Secretary of War to modify them in one particular. Instead of requiring Anderson to defend himself to the last extremity—which was not demanded by any principle of honor or any military rule—he was required to defend himself until no reasonable hope should remain of saving the fort in which he might happen to be. This modification was approved by General Scott.

The instructions, therefore, under which Anderson acted, authorized him to remove his force to any other of the three forts whenever either of them should be attacked, or an attempt should be made to take possession of it, or whenever he might have tangible evidence of a design to proceed to a hostile act. In all this, the Government was acting on the defensive, and was empowering its officer to put his force into either of its forts where, in his judgment, his power of resistance would be most increased. To suppose, therefore, that after these instructions had gone to Anderson, the President made an agreement with certain members of Congress from South Carolina, that the status quo in Charleston harbor, in respect to the three forts, should not be changed, is to suppose something in the highest degree incredible.

4th. The communication between the President and the South Carolina members of Congress was both in writing and in two personal interviews. The written communication remains. Of what took place at the last interview there is an account by Mr. Buchanan himself, founded on memoranda which he made immediately after these gentlemen had left his presence. The first personal interview took place on the 8th of December. The conversation related to the best means of avoiding a hostile collision between the Federal Government and the State of South Carolina. The President desired that the verbal communication should be put in writing, and brought to him in that form. Accordingly on the 10th of December, the same gentlemen brought to him the following letter, signed by five members of Congress from South Carolina, and dated on the previous day:

To His Excellency James Buchanan,

President of the United States:

In compliance with our statement to you yesterday, we now express to you our strong convictions that neither the constituted authorities nor any body of the people of the State of South Carolina will either attack or molest the United States forts in the harbor of Charleston previously to the action of the convention, and we hope and believe, not until an offer has been made through an accredited representative to negotiate for an amicable arrangement of all matters between the State and the Federal Government, provided that no reinforcements shall be sent into those forts, and their relative military status remain as at present.
