On July 2, 1862, President Abraham Lincoln issued a call for troops for the Union Army. Men from Monroe, Hillsdale and Lenawee counties met in Hillsdale to form the Eighteenth Michigan Infantry Regiment. Local mill owner Lewis Emery volunteered this land for the regiment's use. Near here they created Camp Woodbury, named for Colonel Dwight Woodbury from Adrian. The men trained at Camp Woodbury from July to August. The regiment was mustered into service on August 26, 1862, under the command of Colonel Charles Doolittle.
