On November 7, 1861, Union forces under Ulysses S. Grant overrun a Confederate camp at the Battle of Belmont, Missouri, but are forced to flee when additional Confederate troops arrive. Although Grant claimed victory, the Union gained no ground and left the Confederates in firm control of that section of the Mississippi River.
This engagement was part of Grant’s plan to capture the Confederate stronghold at Columbus, Kentucky, just across the river from Belmont, by first driving away the Confederate garrison at Belmont. General Leonidas Polk, Confederate commander at Columbus, had posted about 1,000 men around Belmont to protect both sides of the river. On the evening of November 6, Grant sailed 3,000 troops down the Mississippi River from Cairo, Illinois. They landed early on November 7, just three miles above Belmont, and proceeded to attack.
