The first occasion on which the President definitely discussed emancipation plans with members of his Cabinet, according to Secretary Welles, was on the 13th of July, 1862.  On that day, says Mr. Welles, “President Lincoln invited me to accompany him in his carriage to the funeral of an infant child of Mr. Stanton.  Secretary Seward and Mrs. Frederick Seward were also in the carriage.  Mr. Stanton occupied at that time for a summer residence the house of a naval officer, some two or three miles west or northwest of Georgetown.  It was on this occasion and on this ride that he first mentioned to Mr. Seward and myself the subject of emancipating the slaves by proclamation in case the Rebels did not cease to persist in their war on the Government and the Union, of which he saw no evidence.  He dwelt earnestly on the gravity, importance, and delicacy of the movement; said he had given it much thought, and had about come to the conclusion that it was a military necessity absolutely essential for the salvation of the Union; that we must free the slaves or be ourselves subdued, etc....  This was, the President said, the first occasion when he had mentioned the subject to anyone, and wished us to frankly state how the proposition struck us.  Mr. Seward said the subject involved consequences so vast and momentous that he should wish to bestow on it mature reflection before giving a decisive answer; but his present opinion inclined to the measure as justifiable, and perhaps he might say expedient and necessary.  These were also my views.  Two or three times on that ride the subject, which was of course an absorbing one for each and all, was adverted to; and before separating, the President desired us to give the question special and deliberate attention, for he was earnest in the conviction that something must be done.  It was a new departure for the President, for until this time, in all our previous interviews, whenever the question of emancipation or the mitigation of slavery had been in any way alluded to, he had been prompt and emphatic in denouncing any interference by the General Government with the subject.  This was, I think, the sentiment of every member of the Cabinet, all of whom, including the President, considered it a local, domestic question, appertaining to the States respectively, who had never parted with their authority over it.  But the reverses before Richmond, and the formidable power and dimensions of the insurrection, which extended through all the Slave States, and had combined most of them in a confederacy to destroy the Union, impelled the Administration to adopt extraordinary measures to preserve the national existence.  The slaves, if not armed and disciplined, were in the service of those who were, not only as field laborers and producers, but thousands of them were in attendance upon the armies in the field, employed as waiters and teamsters, and the fortifications and intrenchments were constructed by them.”
