 In the intervening time, the state endured widespread guerrilla warfare in which Southern partisan rangers and bushwhackers battled Kansas-based irregulars known as Jayhawkers and Redlegs or "Redleggers" (from the red gaiters they wore around their lower legs) and their Union allies.Jayhawker raids against perceived civilian "Confederate sympathizers" alienated Missourians and made maintaining the peace even harder for the Unionist provisional government.As Major General Henry Halleck wrote General John C. Frémont in September 1861, Jayhawker raider Jim Hale had to be removed from the Kansas border as "A few more such raids" would render Missouri "as unanimous against us as is Eastern Virginia."
