Charles Rainsford Jennison also known as "Doc" Jennison (June 6, 1834 – June 21, 1884) was a member of the anti-slavery faction during Bleeding Kansas, a famous Jayhawker, and a member of the Kansas State Senate in the 1870s. He later served as a Unioncolonel and as a leader of Jayhawker militias during the American Civil War, until being dishonorably discharged for murder and robbery.
While some other prominent leaders of irregulars in the Bleeding Kansas border conflict shared these traits, Jennison was distinguished by his blatant plunder for personal gain.[3] Jennison cooperated with James Montgomery in opposing pro-slavery settlers and irregulars believed to be in league with Border Ruffians. In command of nine men, Jennison "tried" and hanged Russell Hinds near the state line at Mine Creek for the offense of helping to return a fugitive slave to his master in Missouri. Returning a slave was not only legal, but required at the time under the Fugitive Slave Act.[4]
Hinds had rejected the standard $25 reward ($515 in 2005 dollars), but did accept $5 reimbursement for his expenses in transporting the slave, who had agreed to return to his master while awaiting legal emancipation. The acceptance of the reimbursement was enough to convince Jennison to hand down a death sentence.
On October 28, 1861, Jennison completed the organization and mustering of his 7th Kansas Cavalry. The regiment would become known as "Jennison's Jayhawkers." It immediately took to the field patrolling the Kansas-Missouri border to prevent the secessionist under Sterling Price from crossing.
Jennisons was a resolute abolitionist; his sentiments on the matter were the subject of an article in Horace Greeley's New York Daily Tribune. The article reported Jennison as refusing to allow non-abolitionist soldiers to serve under his command, and asserting that "the slaves of [southerners] can always find a protection in... [my] camp, and they will be defended to the last man and bullet."
In a particularly egregious incident late in the war, Jennison shot and killed 66 year old civilian David Gregg "on the public highway north of Parkville [sic], Platte Co. Mo." on September 15, 1864.
Colonel Jennison commanded a mixed brigade of Kansas militia and volunteers resisting Price's Raid in October 1864.[10] However, in December he was arrested as the result of plundering while returning through Missouri after the pursuit of Price. Jennison was court-martialled and convicted on June 23, 1865, whereupon he was dishonorably dismissed from the service.[11]
