Arkansas held a very important position for the Rebels, maintaining control of the Mississippi River and surrounding Southern states. The bloody Battle of Wilson's Creek just across the border in Missouri shocked many Arkansans who thought the war would be a quick and decisive Southern victory. Battles early in the war took place in northwest Arkansas, including the Battle of Cane Hill, Battle of Pea Ridge, and Battle of Prairie Grove. Union general Samuel Curtis swept across the state to Helena in the Delta in 1862. Little Rock was captured the following year. The government shifted the state Confederate capital to Hot Springs, and then again to Washington from 1863 to 1865, for the remainder of the war. Throughout the state, guerrilla warfare ravaged the countryside and destroyed cities. Passion for the Confederate cause waned after implementation of programs such as the draft, high taxes, and martial law.
