about a third or fourth of the Confederates then in Arkansas. A few hundred men had managed to escape back to Holmes. Union losses were 1,092 men. McClernand's force had suffered 1,061 casualties, and Porter 31. Grant has originally thought the expedition a waste of time, and had ordered McClernand back to the Vicksburg area as soon as he found out about the Arkansas Post movement. Grant later sent a disapproving letter to Halleck who gave him permission to reassign McClernand. McClernand made plans and orders for a movement against Little Rock, but this was overruled by Grant, who came down the Mississippi to take overall command of the army. Porter and Sherman were able to convince Grant of the military value of the Arkansas Post expedition. Grant later noted that the Confederate force at Arkansas Post could have proved problematic if left untended. On January 18, or 19, the Army of the Mississippi was dissolved, and McClernand became a corps commander under Grant. Part of the battlefield is located within Arkansas Post, although have been submerged due to river course changes and the construction of the Arkansas Post Canal.
