Following a massacre of men and boys and the burning of Lawrence, Kansas, by Confederate bushwhackers in the summer of 1863, the United States General Ewing ordered the evacuation of the civilian population from rural areas of Bates and nearby counties except for within a mile of certain Union-controlled cities, in order to cut off sources of support for Confederate insurgents. This was done under Order No. 11. The county had been a base of Confederate guerrillas. But, Ewing's order generated outrage and added to support of guerrillas in some areas.
