William McKnight was a member of the Seventh Ohio Volunteer Cavalry from September 1862 until his death in June of 1864. During his time of service, McKnight penned dozens of emotion-filled letters, primarily to his wife, Samaria, revealing the struggles of an entire family both before and during the war. This collection of more than one hundred letters provides in-depth accounts of several battles in Kentucky and Tennessee, such as the Cumberland Gap and Knoxville campaigns that were pivotal events in the Western Theater.
