General Sill was a classmate of mine at the Military Academy, having
graduated in 1853. On graduating he was appointed to the Ordnance
Corps, and served in that department at various arsenals and ordnance
depots throughout the country till early in 1861, when he resigned to
accept a professorship of mathematics and civil engineering at the
Brooklyn Collegiate and Polytechnic Institute. At the breaking out
of the war he immediately tendered his services to the Government,
and soon rose to the colonelcy of the Thirty-Third Ohio Volunteers,
and afterward to the rank of brigadier-general. I knew him well, and
was glad that he came to my division, though I was very loth to
relieve Colonel Greusel, of the Thirty-Sixth Illinois, who had
already indicated much military skill and bravery, and at the battle
of Perryville had handled his men with the experience of a veteran.
Sill's modesty and courage were exceeded only by a capacity that had
already been demonstrated in many practical ways, and his untimely
death, almost within a month of his joining me, abruptly closed a
career which, had it been prolonged a little more, not only would
have shed additional lustre on his name, but would have been of

Colonel Schaefer, of the Second Missouri Infantry, had been absent on
sick-leave during the Kentucky campaign, but about this date he
returned to duty, and by seniority fell in command of the second
brigade. He was of German birth, having come from Baden, where,

of his State. He took part as an insurgent in the so-called
revolution which occurred at Baden in that year, and, compelled to
emigrate on the suppression of the insurrection, made his way to this
country and settled in St. Louis. Here the breaking out of the war
found him, and through the personal interest which General Sigel took
in him he was commissioned a colonel of volunteers. He had had a
pretty fair education, a taste for the military profession, and was
of tall and slender build, all of which gave him a student-like
appearance. He was extremely excitable and nervous when anticipating
a crisis, but always calmed down to cool deliberation when the
critical moment came. With such a man I could not be less than well
satisfied, although the officer whom he replaced--Colonel Laiboldt
--had performed efficient service and sho
