While the Confederacy fought the Union to a bloody stalemate in the East, the Union army was much more successful in the West. Confederate insurrections in Missouri were put down by the federal government by 1863, despite the initial Confederate victory at Wilson's Creek near Springfield, Missouri. After the Battle of Perryville, the Confederates were also driven from Kentucky, resulting in a major Union victory. Lincoln once wrote of Kentucky, "I think to lose Kentucky is nearly the same as to lose the whole game." The fall of Vicksburg gave the Union control of the Mississippi River and cut the Confederacy in two. Sherman's successes in Chattanooga and then Atlanta left few Confederate forces to resist his destruction of Georgia and the Carolinas. The Dakota War broke out in Minnesota in 1862.
