American Civil War: The three-day Battle of Arkansas Post concludes as General John McClernand and Admiral David Dixon Porter capture Fort Hindman and secure control over the Arkansas River for the Union.

The Battle of Arkansas Post, also known as the Battle of Fort Hindman, was fought from January 9 to 11, 1863, along the Arkansas River at Arkansas Post, Arkansas, as part of the Vicksburg campaign of the American Civil War. Confederate forces constructed Fort Hindman near Arkansas Post in late 1862. Also in late 1862, Major General John A. McClernand of the Union army was authorized to recruit troops in the Midwest for an expedition down the Mississippi River against Vicksburg, Mississippi. Union Major General Ulysses S. Grant began an overland campaign against Vicksburg along the Mississippi Central Railroad in November. He and Union General-in-Chief Henry Halleck did not trust McClernand, and through machinations placed the start of the riverine movement against Vicksburg under the command of Major General William T. Sherman before McClernand could arrive. Sherman's movement was defeated at the Battle of Chickasaw Bayou in late December, and Confederate cavalry raids forced Grant to abandon his overland campaign.
