After the victory at Newtonia, Union Major General Curtis pressed to continue his pursuit of the retreating Confederates. But Major General Pleasonton had received a telegram from his superior, Major General William S. Rosecrans, to have the Department of the Missouri Brigades (Sanborn, McNeil, Philips, Benteen) withdraw to their home bases. Now Curtis only had about 2,500 men in Blunt's Division to continue the pursuit. Curtis immediately sent a telegram to General-in-Chief Ulysses S. Grant asking the Missouri Cavalry Brigades be returned so he could continue the pursuit of Price's Army. Grant agreed and ordered the Missouri Cavalry Brigades to continue the pursuit. Curtis recalled the brigades, but it took time for them to respond. As it turned out, only Benteen was able (or willing) to rejoin Curtis. Curtis continued the pursuit but never did catch up to Price's Army again. Price and the remnants of his Army of Missouri crossed the Arkansas River on November 7th. Curtis called off his pursuit.

Price's Army continued his retreat south through Indian Territory. During this stage of the retreat, there was little food available and the troops suffered terribly from the cold and lack of food. Many men and horses died along the way. By the time Price crossed into Texas most of his "army" had melted away. Price finally arrived in Laynesport, Arkansas on December 2, 1864.

In his official report, Price was optimistic. He had marched 1,454 miles, fought in 43 engagements with the enemy and captured a large amount of Federal stores. He did not report that he had lost five thousand small arms, all his artillery and half of his army. Missouri Governor in exile Thomas Reynolds was harsh in his public criticism. He accused Price of "glaring mismanagement and distressing mental and physical military incapacity."
