"General Orders No. 33," issued from "Headquarters Department of Washington," July 17, 1861, "By command of Brigadier General Mansfield, Theo. Talbot, Assistant Adjutant General," were to this effect: "Fugitive Slaves will under no pretext whatever, be permitted to reside, or be in any way harbored, in the quarters or camps of the troops serving in this Department. Neither will such Slaves be allowed to accompany troops on the march. Commanders of troops will be held responsible for a strict observance of this order." And early in August a Military order was issued at Washington "that no Negroes, without sufficient evidence of their being Free or of their right to travel, are permitted to leave the city upon the cars."

But Bull Run did much to settle the Military as well as public mind in proper grooves on this subject.

Besides employing Negro Slaves to aid Rebellion, by the digging of ditches, the throwing up of intrenchments, and the erection of batteries, their Rebel masters placed in their hands arms with which to shoot down Union soldiers at the Battle of Bull Run, which, as we have seen, occurred on Sunday, July 21, 1861—and resulted in a check to the Union Cause.

The terror and confusion and excitement already referred to, that prevailed in Washington all that night and the next day, as the panic-stricken crowd of soldiers and civilians poured over the Long Bridge, footsore with running, faint with weariness, weak with hunger, and parched with thirst and the dust of the rout, can hardly be described.

But, however panicky the general condition of the inhabitants of the National Capital, the Congress bravely maintained its equanimity.

In the Senate, on the day following the disaster, a bill touching the Confiscation of Property used for insurrectionary purposes being up for consideration, the following amendment was offered to it:

"And be it further enacted, That whenever any person claiming to be entitled to the Service or Labor of any other Person under the laws of any State, shall employ such Person in aiding or promoting any Insurrection, or in resisting the Laws of the United States, or shall permit him to be so employed, he shall forfeit all right to such Service or Labor, and the Person whose Labor or Service is thus claimed shall be thenceforth discharged therefrom, any law to the contrary notwithstanding."

This amendment, emancipating Slaves employed by their masters to aid Rebellion, was adopted by 33 yeas to 6 nays.

As showing the feeling expressed right upon the very heels of what seemed to be a great disaster, and when rumor, at any rate, placed the victorious Enemy at the very gates of the Capital City, a few lines from the debate may be interesting.

Mr. Trumbull said: "I am glad the yeas and nays have been called to let us see who is willing to vote that the Traitorous owner of a Negro shall employ him to shoot down the Union men of the Country, and yet insist upon restoring him to the Traitor that owns him. I understand that Negroes were in the fight which has recently occurred. I take it that Negroes who are used to destroy the Union, and to shoot down the Union men by the consent of Traitorous masters, ought not to be restored to them. If the Senator from Kentucky is in favor of restoring them, let him vote against the amendment."
