"A number of irresponsible men, of Union sentiments, organized a guerrilla band. They took advantage of the presence of the force here* to commit some jayhawking excesses in the vicinity. Some thirty men visited a secession farmer named Hunter, and several of his neighbors of the same stripe, claiming to be connected with the troops. they took a quantity of stuff, arms, horses, &c., Col. Jennison, on learning of these acts, ordered them to be disarmed, and took them prisoners. The stolen property was returned to its owners. Jayhawking can't be done in an irregular manner by any one."
It was time, it seems, for Jayhawking to be professionalized.
* That force being Jennison's Seventh, which in its 3-month stay in Missouri would burn several hundred houses, appropriate untold horses and mules, and send 1700 "contrabands" to Kansas with oxen, horses, and wagons full of household goods.
