Start Date 1/9/1863 Battle Arkansas Post Other Names Fort Hindman Location 1 Arkansas County , AR State AR Campaign Operations against Vicksburg (1862-1863) Principal US Commanders Rear Adm. David D. Porter and Maj. Gen. John A. McClernand [US] Principal CS Commanders Brig. Gen. Thomas J. Churchill [CS] Forces Engaged Army of the Mississippi [US]; Fort Hindman Garrison [CS] Description From Fort Hindman, at Arkansas Post, Confederates had been disrupting Union shipping on the Mississippi River. Maj. Gen.
John McClernand, therefore, undertook a combined force movement on Arkansas Post to capture it. Union boats began
landing troops near Arkansas Post in the evening of January 9, 1863. The troops started up river towards Fort Hindman.
Maj. Gen. William T. Sherman's corps overran Rebel trenches, and the enemy retreated to the protection of the fort and
adjacent rifle-pits. Rear Adm. David Porter, on the 10th, moved his fleet towards Fort Hindman and bombarded it
withdrawing at dusk. Union artillery fired on the fort from artillery positions across the river on the 11th, and the infantry
moved into position for an attack. Union ironclads commenced shelling the fort and Porter's fleet passed it to cutoff any
retreat. As a result of this envelopment, and the attack by McClernand's troops, the Confederate command surrendered in
the afternoon. Although Union losses were high and the victory did not contribute to the capture of Vicksburg, it did
eliminate one more impediment to Union shipping on the Mississippi. Result(s) Union victory End Date 1/11/1863 # Days Battle 3 Total Est Casualties 6547 US Est Casualties 1047 CS Est Casualties 5500 Est Casualties 6,547 total (US 1,047; CS 5,500)
I remember a brief description of the action in Capt. Foster's One of Cleburne's Command talking about his regiment, the 24th Texas Dismounted Cavalry, being captured there in Jan., 1863 before their parole and transfer to Pat Cleburne's division later that year.
