……..

The Thirteenth Regiment Illinois Infantry was one of the
regiments organized under the act known as the Ten Regiment
Bill.

. . . . . On the 16th of June it was ordered to Caseyville, Ill., 10
miles east of St. Louis, and on the 5th day of July it passed
through St. Louis to Rolla, Mo., where it remained until the
spring of 1862.

While stationed at Rolla it was engaged in guarding supply
trains to and from General Lyon's army, in suppressing
guerrilla bands in that part of the State, and was a part of
General Fremont's force that went to Springfield, Missouri, in
the fall of 1861, after General Price, when the Regiment was
well and favorably known as "Fremont's Grey Hounds," a name
given to them by General Fremont himself, on the evening the
Regiment joined his army at Bolivar, in splendid shape, after a
day's march of 42 miles. . . .
