Battle of Belmont - Background

Background

At the beginning of the war, the critical border state of Kentucky, with a pro-Confederate governor but a largely pro-Union legislature, declared neutrality between the opposing sides. Pro-Confederates crossed into Tennessee to enlist, but the Union men openly formed a recruiting camp inside Kentucky. Using this as an excuse, Confederate Maj. Gen. Leonidas Polk violated the state's neutrality on September 3, 1861, by occupying Columbus, a key position on the bluffs overlooking the Mississippi River. Two days later Union Brig. Gen. Ulysses S. Grant seized Paducah. Grant, commanding the District of Southeast Missouri, requested permission from theater commander Maj. Gen. John C. Frémont to attack Columbus, but no orders came. For the next two months only limited demonstrations were conducted against the Confederates.

Frémont learned the Confederates planned to reinforce their forces in Arkansas, and on November 1 he ordered Grant to make a feint toward Columbus to keep the Confederates there. Grant sent about 3,000 men under Col. Richard Oglesby into southeastern Missouri. Grant then learned that Confederate reinforcements were moving into Missouri to intercept Oglesby's column. He sent reinforcements and also ordered Brig. Gen. Charles F. Smith to move from Paducah into southwestern Kentucky to distract the Confederates. Grant chose to attack Belmont, a ferry landing and tiny hamlet of just three shacks, about 2,000 feet across the river from Columbus. Grant's Expeditionary Command numbered 3,114 officers and men, and was organized into two brigades under Brig. Gen. John A. McClernand and Col. Henry Dougherty, two cavalry companies, and an artillery battery. On November 6, escorted by the gunboats USS Tyler and USS Lexington, Grant's men left Cairo on the steamboats Aleck Scott, Chancellor, Keystone State, Belle Memphis, James Montgomery, and Rob Roy.

Confederate Maj. Gen. Leonidas Polk had about 5,000 troops guarding Columbus. When he learned of Grant's movements, he assumed that Columbus was their primary objective and that Belmont was a feint. He ordered 2,700 under Brig. Gen. Gideon J. Pillow to Belmont, retaining the rest to defend Columbus.

When he reached Belmont, Grant found Camp Johnston, a small Confederate observation post, supported by an artillery battery. He decided to attack to keep the Confederates from reinforcing Maj. Gen. Sterling Price or Brig. Gen. M. Jeff Thompson of the Missouri State Guard, and to protect Oglesby's exposed left flank.
