"The policy of the Government must be supported by concentrations of Military power. The National Forces should not be dispersed in expeditions, posts of occupation, and numerous armies, but should be mainly collected into masses, and brought to bear upon the Armies of the Confederate States. Those Armies thoroughly defeated, the political structure which they support would soon cease to exist, "In carrying out any system of policy which you may form, you will require a Commander-in-chief of the Army, one who possesses your confidence, understands your views, and who is competent to execute your orders, by directing the Military Forces of the Nation to the accomplishment of the objects by you proposed. I do not ask that place for myself, I am willing to serve you in such position as you may assign me, and I will do so as faithfully as ever subordinate served superior. "I may be on the brink of Eternity; and as I hope forgiveness from my Maker, I have written this letter with sincerity towards you and from love for my Country. "Very respectfully, your obedient servant, "GEORGE B. MCCLELLAN, "Major-General Commanding. "His Excellency A. LINCOLN, President." July 12, 1862, Senators and Representatives of the Border Slave-holding States, having been specially invited to the White House for the purpose, were addressed by President Lincoln, as follows: "GENTLEMEN:--After the adjournment of Congress, now near, I shall have no opportunity of seeing you for several months. Believing that you of the Border States hold more power for good than any other equal number of members, I feel it a duty which I cannot justifiably waive, to make this appeal to you. "I intend no reproach or complaint when I assure you that, in my opinion, if you all had voted for the Resolution in the Gradual Emancipation Message of last March, the War would now be substantially ended. And the plan therein proposed is yet one of the most potent and swift means of ending it. Let the States which are in Rebellion see definitely and certainly that in no event will the States you represent ever join their proposed Confederacy, and they cannot much longer maintain the contest. "But you cannot divest them of their hope to ultimately have you with them so long as you show a determination to perpetuate the Institution within your own States. Beat them at elections, as you have overwhelmingly done, and nothing daunted, they still claim you as their own. You and I know what the lever of their power is. Break that lever before their faces, and they can shake you no more forever.
