In January 1864, Confederate General Patrick Cleburne, of the Army of Tennessee, proposed emancipating and arming the slaves. Davis, when he heard of it, turned it down and ordered it kept secret. Evans notes that Benjamin "had been thinking in similar terms for much longer, and perhaps the recommendation of so respected an officer was just the impetus he needed." The year 1864 was a disastrous one for the Confederacy, with Lee forced within siege lines at Petersburg and Union General William T. Sherman sacking Atlanta and devastating Georgia on his march to the sea. Benjamin urged Davis to send the secretary's fellow Louisianan, Duncan Kenner, to Paris and London, with an offer of emancipation in exchange for recognition. Davis was only willing to offer gradual emancipation, and both Napoleon and Palmerston rejected the proposal. Benjamin continued to press the matter, addressing a mass meeting in Richmond in February 1865 in support of arming the slaves and emancipating them. A bill eventually emerged from the Confederate Congress in March, but it had many restrictions, and it was too late to affect the outcome of the war.
