General Bates, who was the senior, was a graduate of West Point, who had served some years in the regular army, but had resigned and adopted the profession of the law.

He lived at Cincinnati, and organized his brigade in that city.

They marched to Camp Dennison on the 20th of May, when, by virtue of his seniority, General Bates assumed command of the camp in McClellan's absence.

His brigade consisted of the Fifth, Sixth, Ninth, and Tenth regiments, and encamped on the east side of the railroad in the bend of the river.

General Schleich was a Democratic senator, who had been in the state militia, and was also one of the drill-masters of the legislative squad which had drilled upon the Capitol terrace.
