engineer officer. I had met Colonel Robert McCook at Camp Dennison,
and now that it was intimated that he would be for some days under
my command, I recalled a scene I had witnessed there which left many
doubts in my mind whether he would prove an agreeable subordinate. I
had gone, one morning, to General Bates's office, and as I entered
found McCook expressing himself with more vigor than elegance in
regard to some order which had been issued respecting his regiment.
My presence did not seem to interfere with the fluency of his
remarks or the force of his expletives, but after a moment or two he
seemed to notice a look of surprise in my face, and his own

bluff exterior and rough speech, with real courage, a quick eye for
topography, and no lack of earnest subordination when work was to be

of the Twenty-third Ohio upon Rosecrans's promotion. Like Rosecrans,
he was a Roman Catholic, though himself of Puritan descent. It seems
that at the time of the Puseyite movement in England and in this
