Turchin, John B., brigadier-general, was born in Russia,
but in early life migrated to America and at the time of the
outbreak of the Civil war was living in the state of Illinois.
On June 17, 1861, he was commissioned colonel of the 19th Ill.
infantry, and having been a colonel of staff in the Russian
Guards he paid particular attention at the start to the drill
and discipline of his regiment, utilizing the first two weeks
in camp to the utmost to make the regiment as efficient as
possible for the service before it. He pursued his endeavors
in that respect every time the regiment was not on the march
and finally succeeded in making the 19th Ill. infantry one of
the best drilled regiments in the western armies. On the
evening of July 13 he arrived at Quincy with his regiment, and
on the 14th received orders from Gen. Hurlbut to relieve the
21st Ill. infantry, on the Hannibal & St. Joseph railroad from
Quincy to Palmyra, and between the latter place and Hannibal,
Mo. During their two weeks, stay in that locality the men of
his command, besides guarding several important bridges on the
railroad, made several expeditions to different points in the
neighborhood, chased newly organized Confederate companies out
of various plantations, destroyed their barracks and
provisions, obliged the citizens to give pledges not to
support any more such companies, encouraged formations of
home-guard companies at Palmyra and Newark, suppressed the
secessionists and encouraged the Unionists. So well did Col.
Turchin perform the work assigned him that, on July 17, 1862,
he was commissioned brigadier-general of volunteers, in which
capacity he served until Oct. 4, 1864, when he resigned from
the army and resumed the peaceful pursuits of civil life.
Gen. Turchin died June 19, 1901.
