There was yet a further preliminary to the great final struggle. On March 1, 1864, pursuant to an Act of Congress which was necessary for this object, Lincoln conferred upon Grant the rank of Lieutenant-General, never held by any one else since Washington, for it was only brevet rank that was conferred on Scott. Therewith Grant took the command, under the President, of all the Northern armies. Grant came to Washington to receive his new honour. He had taken leave of Sherman in an interchange of letters which it is good to read; but he had intended to return to the West. Sherman, who might have desired the command in the West for himself, had unselfishly pressed him to return. He feared that the dreaded politicians would in some way hurt Grant, and that he would be thwarted by them, become disgusted, and retire; they did hurt him, but not then, nor in the way that Sherman had expected. Grant, however, could trust Sherman to carry out the work he wanted done in the West, and he now saw that, as Lincoln might have told him and possibly did, the work he wanted done in the East must be done by him. He went West again for a few days only, to settle his plans with Sherman. Sherman with his army of 100,000 was to follow Johnston's army of about 60,000, wherever it went, till he destroyed it. Grant with his 120,000 was to keep up an equally unfaltering fight with Lee's army, also of 60,000. There was, of course, nothing original about this conception except the idea, fully present to both men's minds, of the risk and sacrifice with which it was worth while to carry it out. Lincoln and Grant had never met till this month. Grant at the first encounter was evidently somewhat on his guard. He was prepared to like Lincoln, but he was afraid of mistaken dictation from him, and determined to discourage it. Also Stanton had advised him that Lincoln, out of mere good nature, would talk unwisely of any plans discussed with him. This was probably quite unjust. Stanton, in order to keep politicians and officers in their places, was accustomed to bite off the noses of all comers. Lincoln, on the contrary, would talk to all sorts of people with a readiness which was sometimes astonishing, but there was a good deal of method in this--he learnt something from these people all the time--and he certainly had a very great power of keeping his own counsel when he chose. In any case, when Grant at the end of April left Washington for the front, he parted with Lincoln on terms of mutual trust which never afterwards varied. Lincoln in fact, satisfied as to his general purpose, had been happy to leave him to make his plans for himself. He wrote to Grant: "Not expecting to see you again before the spring campaign begins, I wish to express in this way my entire satisfaction with what you have done up to this time so far as I understand it. The particulars of your plan I neither know nor seek to know.
