The question of emancipation appeared in another form when, upon the capture of Port Royal the previous November, many slaves, abandoned by the fleeing slave-holders, sought protection in the Union army. These slaves, thus dislodged by the misfortunes of war, outnumbered the whites five to one and had to be organized in groups for government protection. Relief societies in Boston, New York, and Philadelphia sent funds and teachers for the slaves. This educational enterprise received the official sanction of Secretary Chase at President Lincoln's request. Wishing further to improve their condition, General David Hunter, commander of the Department of the South, issued on May 9, 1862, an order of military emancipation, proclaiming the Department of the South under martial law and declaring persons in Georgia, Florida, and South Carolina, heretofore held as slaves, forever free.[28] Hunter regarded this an act of military necessity, not an instrument of political import as General Fremont's proclamation in Missouri, for Hunter's forces were insufficient for offensive movements, and he was doing this as the first step toward training and arming Negroes within his lines. Assuming that the instructions of the War Department conferred the necessary authority he proclaimed the order without delay. The news of this proclamation did not travel rapidly. It was published in the newspapers one week later, owing to the slow mail by sea from the South. By this means even Lincoln first learned of this decree, on account of which he was being assailed in many parts. When the news reached Lincoln he took decisive and prompt action. On May 19, he published a proclamation in which he revoked the order of emancipation and recited that the Government had no knowledge of such a decree nor had it authorized General Hunter to give such an order.[29] Lincoln, however, used this occasion for an admonition to the border slave States, although he carefully distinguished between the limited powers of the commanders in the field and his full executive authority. He reminded the border States of the joint resolution passed by Congress, to authorize compensated emancipation, and he warned them not to neglect this opportunity to obtain financial indemnity, for the "signs of the times" were multiplying to a degree that should have convinced the border States that slavery was doomed.
