I hereby certify, in pursuance of law and the foregoing order, the
said "Shadrach" named in the foregoing warrant and order, was being
detained in my custody in the Court Room of the United States, in
the Court House, in said Boston, when the door of said room, which
was being used as a prison, was forced open by a mob, and the said
"Shadrach" forcibly rescued from my custody. I also annex hereto,
and make part of my return an original [printed] deposition, of the
circumstances attending the arrest and rescue, and have not been
able to retake said Shadrach, and cannot now have him before said
Commissioner for reasons above stated.
