It was when General Grant was fighting his way through the Wilderness to Richmond, on the 'line' he meant to pursue 'if it took all summer', and every reverse to his arms was made the occasion for a fresh demand for peace without emancipation, that President Lincoln did me the honor to invite me to the Executive Mansion for a conference on the situation. I need not say I went most gladly. The main subject on which he wished to confer with me was as to the means most desirable to be employed outside the army to induce the slaves in the rebel States to come within the Federal lines. The increasing opposition to the war, in the North, and the mad cry against it, because it was being made an abolition war, alarmed Mr. Lincoln, and made him apprehensive that a peace might be forced upon him which would leave still in slavery all who had not come within our lines.
