The Confederate Army constructed an earthen fortification near Arkansas Post to protect the Arkansas River and as a base for disrupting shipping on the Mississippi River. The fort was named Fort Hindman in honor of General Thomas C. Hindman of Arkansas. The fortification was seized by a Federal amphibious force backed by ironclad warships.
The results of the battle were 6,547 total casualties and an end to Confederate interference with Union shipping. US forces suffered 1,047 casualties, while the Confederate forces suffered about 5,500 casualties.
The fort was named FortHindman in honor of General Thomas C. Hindman of Arkansas.
Union artillery fired on the fort from positions across the river on January 11, effectively silencing most of the Confederate guns in the fort, and the infantry moved into position for an attack.
