Some time towards the close of the preceding May, while the National troops were gathered about the capital, and during an evening drive with the President alone in his carriage, Mr. Sumner brought up the subject of Slavery, in order to say that the President was right in his course at that time, but that he must be ready to strike when the moment came. On the day of the disaster he was with the President twice, but made no suggestion then. On the second day thereafter, when the tidings from all quarters showed that the country was aroused to intense action, he visited the President expressly to urge Emancipation. The President received him kindly, and, when Mr. Sumner said that he had come to make an important recommendation with regard to the conduct of the war, replied promptly, that he was occupied with that very question, and had something new upon it. Mr. Sumner, thinking that he was anticipated, said, “You are going against Slavery!” “Oh, no, not that!” he replied, impatiently. “I am sorry,” said Mr. Sumner, when the President, with increasing impatience, reminded him of the evening drive in his carriage, and then retorted: “Did you not then approve my course?” “Certainly,” said Mr. Sumner, “at that time; but I said also that you must be ready to strike at Slavery, and now the moment has come. Of this I have no doubt.” And he proceeded to urge his reasons, but could not satisfy the President. The interview, which was late in the evening, did not terminate till midnight. So completely had Mr. Sumner acted on the idea of waiting for a moment to strike, that in two different bills introduced by him before the disaster at Bull Run, one, July 16th, entitled, “For the confiscation of property of persons in rebellion against the Constitution and Laws of the United States,” and the other, July 18th, entitled, “For the punishment of conspiracy and kindred offences against the United States, and for the confiscation of the property of the offenders,” there is no open mention of Slavery. In the first bill there is a provision for the forfeiture of “the property, real and personal, of every kind whatsoever, and wheresoever situated within the limits of the United States, belonging to any person owing allegiance to the United States, who shall be found in arms against the United States, or shall give any aid or comfort to their enemies.” The other bill contains a clause equally stringent, but general in character. But after that disaster to our arms, he was satisfied the time had come for a full exercise of the War Power, and he desired earnestly to have the President lead the way openly and without reservation.
