Trumbull insisted that Slavery was at the bottom of all the internal troubles with which the Nation had from its birth been afflicted, down to this wicked Rebellion, with all the resulting "distress, desolation, and death;" and that by 1860, it had grown to such power and arrogance that "its advocates demanded the control of the Nation in its interests, failing in which, they attempted its overthrow." He reviewed, at some length, what had been done by our Government with regard to Slavery, since the breaking out of hostilities against us in that mad attempt against the National life; how, "in the earlier stages of the War, there was an indisposition on the part of the Executive Authority to interfere with Slavery at all;" how, for a long time, Slaves, escaping to our lines, were driven back to their Rebel masters; how the Act of Congress of July, 1861, which gave Freedom to all Slaves allowed by their Rebel masters to assist in the erection of Rebel works and fortifications, had "not been executed," and, said Mr. Trumbull, "so far as I am advised, not a single Slave has been set at liberty under it;" how, "it was more than a year after its enactment before any considerable number of Persons of African descent were organized and armed" under the subsequent law of December, 1861, which not only gave Freedom to all Slaves entering our Military lines, or who, belonging to Rebel masters, were deserted by them, or were found in regions once occupied by Rebel forces and later by those of the Union, but also empowered the President to organize and arm them to aid in the suppression of the Rebellion; how, it was not until this law had been enacted that Union officers ceased to expel Slaves coming within our lines--and then only when dismissal from the public service was made the penalty for such expulsion; how, by his Proclamations of Emancipation, of September, 1862, and January, 1863, the President undertook to supplement Congressional action--which had, theretofore, been confined to freeing the Slaves of Rebels, and of such of these only as had come within the lines of our Military power-by also declaring, Free, the Slaves "who were in regions of country from which the authority of the United States was expelled;" and how, the "force and effect" of these Proclamations were variously understood by the enemies and friends of those measures--it being insisted on the one side that Emancipation as a War-stroke was within the Constitutional War-power of the President as Commander-in-Chief, and that, by virtue of those Proclamations, "all Slaves within the localities designated become ipso facto Free," and on the other, that the Proclamations were "issued without competent authority," and had not effected and could not effect, "the Emancipation of a single Slave," nor indeed could at any time, without additional legislation, go farther than to liberate Slaves coming within the Union Army lines.
