The promulgation of this New Year's Proclamation of Freedom unquestionably had a wonderful effect in various ways, upon the outcome of the War. It cleared away the cobwebs which the arguments of the loyal Border-State men, and of the Northern Copperheads and other Disunion and Pro-Slavery allies of the Rebels were forever weaving for the discouragement, perplexity and ensnarement, of the thoroughly loyal out-and-out Union men of the Land. It largely increased our strength in fighting material. It brought to us the moral support of the World, with the active sympathy of philanthropy's various forces. And besides, it correspondingly weakened the Rebels. Every man thus freed from his Bondage, and mustered into the Union Armies, was not only a gain of one man on the Union side, but a loss of one man to the Enemy. It is not, therefore, surprising that the Disunion Conspirators--whether at the South or at the North--were furious. The Chief Conspirator, Jefferson Davis, had already, (December 23, 1862,) issued a proclamation of outlawry against General B. F. Butler, for arming certain Slaves that had become Free upon entering his lines --the two last clauses of which provided: "That all Negro Slaves captured in arms, be at once delivered over to the Executive authorities of the respective States to which they belong, to be dealt with according to the laws of said States," and "That the like orders be executed in all cases with respect to all commissioned Officers of the United States, when found serving in company with said Slaves in insurrection against the authorities of the different States of this Confederacy." He now called the attention of the Rebel Congress to President Lincoln's two Proclamations of Emancipation, early in January of 1863; and that Body responded by adopting, on the 1st of May of that year, a Resolution, the character of which was so cold-bloodedly atrocious, that modern Civilization might well wonder and Christianity shudder at its purport. [It was in these words: "Resolved, by the Congress of the Confederate States of America, In response to the Message of the President, transmitted to Congress at the commencement of the present session, That, in the opinion of Congress, the commissioned officers of the Enemy ought not to be delivered to the authorities of the respective States, as suggested in the said Message, but all captives taken by the Confederate forces ought to be dealt with and disposed of by the Confederate Government.
