Organization
Between 1836 and 1860, four German militia units had been formed in Cincinnati, Ohio. In 1861, in response to a call to arms by President Abraham Lincoln and subsequently by Ohio Governor William Dennison, these units swelled with hundreds of volunteers. Gustav Bergmann, a Cincinnati public school teacher, was the first volunteer to join the unit. The city of Cincinnati gave $250,000.00 for the organization of this unit. Nearly 1,500 men, mostly of German descent, volunteered for the 9th Ohio Infantry Regiment in the first three days. Col. Robert L. McCook, a local lawyer, trained and drilled the new soldiers at Camp Harrison and Camp Dennison, both near the city.
The initial field officers on April 23, 1861, were:
The regiment lost six officers and 85 enlisted men killed and mortally wounded during its three-year term of service. It also lost two officers and 60 enlisted men to disease, for a total of 153.
