American Civil War: Union forces defeated a Confederate cavalry unit in the Van Buren raid, capturing three steamboats, Confederate troops, and various supplies.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction.

The Union was the central government of the United States during the American Civil War. Its civilian and military forces resisted the Confederacy's attempt to secede following the election of Abraham Lincoln as president of the United States. Lincoln's administration asserted the permanency of the federal government and the continuity of the United States Constitution.

The Confederate States of America (CSA), also known as the Confederate States (C.S.), the Confederacy, or the South, was an unrecognized breakaway republic in the Southern United States from 1861 to 1865. It comprised eleven U.S. states that declared secession: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina. These states fought against the United States during the American Civil War.

The Van Buren raid occurred in Crawford County, Arkansas, on December 28, 1862, during the American Civil War. After defeating Confederate forces led by Major General Thomas C. Hindman at the Battle of Prairie Grove on December 7, 1862, Union forces under Brigadiers General James G. Blunt and Francis J. Herron prepared for a raid against the Confederate positions at Van Buren and Fort Smith. Disease, lack of supplies, and desertion had previously forced Hindman to begin withdrawing most of his force from the area. Setting out on December 27, the Union troops struck an outlying Confederate cavalry unit near Drippings Spring, north of Van Buren, on the morning of December 28. The Confederate cavalry fled to Van Buren, which was then overrun by Union troops.
