I ask the acceptance of this resignation. Capt. Lusk has
been in most of the battles including the First Bull Run, from Beaufort to the
death of Major-Gen. Stevens, whose Staff he was on from the date of Gen.
Stevens's promotion to his death. Capt. Lusk, so soon as he heard of the
occupation of Maryland Heights, left New-York City, came to Point of Rocks, and
walked to Harper's Ferry, and volunteered for duty at a moment when I was much
in need of his services, and to make him available I recommended him for the
appointment of Asst. Adjt.Genl. and he was appointed accordingly, with the
expectation that when the prospect of fighting at that point was over, his
resignation would be accepted. Under the circumstances, as Capt. Lusk is on the
point of commencing a professional life in the City of New-York, I ask the
acceptance of his resignation, knowing that there never will be an emergency
like that at Gettysburg and Maryland Heights, that Capt. Lusk will not be found
at the front.
