Charles Rainsford Jennison
(June 6, 1834 – June 21, 1884)
After emigrating to Kansas in the late 1850s, Charles R. “Doc” Jennison's name would become synonymous with “Jayhawking”. Both prior to and during the war, Jennison frequently led his men across the border into Missouri to rob, steal, plunder, and burn whatever they could lay their hands upon.
Twice Jennison was asked by the Governor of Kansas to raise a cavalry regiment to defend Kansas against Southern invasion during the American Civil War. The Seventh Kansas Volunteer Cavalry Regiment would become infamous and would be known as "Jennison's Jayhawkers". After Quantrill's Raid on Lawrence, Jennison would raise the 15th Kansas Volunteer Cavalry Regiment.
Jennison's jayhawking would eventually cause him to be court-martialed and dishonorably discharged from the US Army in 1865.
