George Washington Morgan was an American soldier, lawyer, politician, and diplomat. He fought in the Texas Revolution and the Mexican–American War, and was a general in the Union Army during the American Civil War. Morgan later served as a three-term reconstruction era United States Congressman from Ohio. He also served as the United States Ambassador to Portugal from 1858 to 1861, during the term of President James Buchanan.

The Battle of Arkansas Post, also known as Battle of Fort Hindman, was fought from January 9 to 11, 1863, near the mouth of the Arkansas River at Arkansas Post, Arkansas, as part of the Vicksburg Campaign of the American Civil War. Confederate forces had constructed a fort known as Fort Hindman near Arkansas Post in late 1862. In December of that year, a Union force under the command of Major-General William T. Sherman left for an expedition against Vicksburg, without Major-General John A. McClernand because neither Major-Generals Henry Halleck nor Ulysses S. Grant trusted McClernand. After Sherman's force was repulsed at Chickasaw Bayou, McClernand arrived and took command from Sherman in January 1863.
