Ex-President J. Q. Adams's cogent exposition of the Constitution, twenty-five years before, in that same House, demonstrating not only that Congress had the right but the Constitutional power to so interfere--and his further demonstration April 15, 1842, of his statement that under the laws of War, "when a Country is invaded, and two hostile armies are set in martial array, the Commanders of both Armies have power to Emancipate all the Slaves in the invaded territory"--as not to be overcome by a mere vote of one House, however unanimous. For the time being, however, it contributed, with other circumstances, to confuse the public mind and conscience. Indeed as early as May of 1861, the attitude of our Government and its troops toward Negro Slaves owned or used by Rebels in rebellious States, began to perturb the public, bother the Administration, and worry the Military officers. For instance, in Major-General McClellan's proclamation to the Union men of West Virginia, issued May 26, 1861, he said: "The General Government cannot close its ears to the demand you have made for assistance. I have ordered troops to cross the river. They come as your friends and brothers--as enemies only to armed Rebels, who are preying upon you; your homes, your families, and your property are safe under our protection. All your rights shall be religiously respected, notwithstanding all that has been said by the Traitors to induce you to believe our advent among you will be signalized by an interference with your Slaves. Understand one thing clearly: not only will we abstain from all such interference, but we will, on the contrary, with an iron hand crush any attempt at insurrection on their part." On the other hand, the very next day, May 27, 1861, Major-General Butler, in command of the "Department of A Virginia," wrote to Lieutenant-General Scott as follows: "Since I wrote my last dispatch the question in regard to Slave property is becoming one of very serious magnitude. The inhabitants of Virginia are using their Negroes in the batteries, and are preparing to send the women and children South. The escapes from them are very numerous, and a squad has come in this morning to my pickets bringing their women and children. Of course these cannot be dealt with upon the theory on which I designed to treat the services of able-bodied men and women who might come within my lines, and of which I gave you a detailed account in my last dispatch. I am in the utmost doubt what to do with this species of Property.
