These all expressed their desire to enlist in the service of the United States, and were conducted to the recruiting office on Camden street, to be examined by the surgeons. The women are in number thirty-three. These unfortunates were all liberated in accordance with your orders. It appears from their statements that this slave-pen has been used chiefly for the purpose of holding persons, in evasion of the law of Congress, entitled to their freedom in the District of Columbia, and persons claimed as slaves by rebels or rebel sympathizers. Respectfully submitted.
Wm. Birney, Colonel Second United States Colored Troops, Inspector and Mustering Officer.
