Grant's account of his first conference alone with Lincoln is eloquent of Lincoln's wise war statesmanship "He stated that he had never professed to be a military man or to know how campaigns should be conducted, and never wanted to interfere in them . . . . All he wanted was some one who would take the responsibility and act, and call on him for all the assistance needed, pledging himself to use all the power of the government in rendering such assistance . . . . He pointed out on the map two streams which empty into the Potomac, and suggested that the army might be moved on boats and landed between the mouths of these streams. We would then have the Potomac to bring our supplies and the tributaries would protect our flanks while we moved out. I listened respectfully, but did not suggest that the same streams would protect Lee's flanks while he was shutting us up. I did not communicate my plans to the President; nor did Ito the Secretary of War or to General Halleck."Trust begot trust; and some months later Grant showed war statesmanship of the same magnificent kind. McClellan had become the Democratic candidate for President, to the wellfounded alarm of all who put the Union first. In June, when Grant and Lee were at grips round Richmond, Lincoin was invited to a public meeting got up in honor of Grant with only a flimsy disguise of the ominous fact that Grant, and not Lincoln, might be the Union choice. Lincoln sagaciously wrote back: "It is impossible for me to attend. I approve nevertheless of whatever may tend to strengthen and sustain General Grant and the noble armies now under his command. He and his brave soldiers are now in the midst of their great trial, and I trust that at your meeting you will so shape your good words that they may turn to men and guns, moving to his and their support." The danger to the Union of taking Grant away from the front moved Lincoln deeply all through that anxious summer of '64, though he never thought Grant would leave the front with his work half done. In August an officious editor told Lincoln that he ought to take a good long rest.
Lincoln, however, was determined to stand by his own post of duty and find out from Grant, through their common friend, John Eaton, what Grant's own views of such ideas were. This is Eaton's account of how Grant took it:
"We had been talking very quietly. But Grant's reply came in an instant and with a violence for which I was not prepared. He brought his clenched fists down hard on the strap arms of his camp chair. 'They can't do it. They can't compel me to do it.'
