All the troops but Cumming's brigade returned to their camps on the Missouri shore on the 8th. Colonel Cumming, having charge of the prisoners, returned on the evening of the 9th. General Pope, in his final detailed report giving the result of all the operations, states: "Three generals, two hundred and seventy-three field and company officers, six thousand seven hundred privates, one hundred and twenty-three pieces of heavy artillery, thirty-five pieces of field artillery, all of the very best character and of the latest patterns, seven thousand stand of small arms, tents for twelve thousand men, several wharf-boat loads of provisions, an immense quantity of ammunition of all kinds, many hundred horses and mules, with wagons and harness, etc., are among the spoils." The capture embraced, besides, six steamboats--two of them sunk--the gunboat Grampus, carrying two guns, sunk; and the floating battery, carrying nine guns, which the crew had ineffectually attempted to scuttle before abandoning it. Two of the generals captured were brigadier-generals, Mackall and Gantt; the third was perhaps L.M. Walker. When Major-General McCown was relieved on March 31st by Mackall, McCown and Brigadier-General Trudeau left. Brigadier-General A.P. Stewart had left previously and reported for duty at Corinth. Colonels Walker and Gantt were promoted brigadier-generals after the siege began. General Walker appears, from his report of April 9th, dated St. Francis County, Arkansas, to have left on account of ill-health some time before the surrender. The prisoners embraced, including those on the island surrendered to the navy, seven regiments and one battalion of infantry, one of the regiments having twelve companies--eleven companies of heavy and one of light artillery, two companies of cavalry, the officers and crews of the floating battery and the steamboats, and laborers and employees. The Mississippi was now open to Fort Pillow. General Halleck telegraphed to General Pope: "I congratulate you and your command on your splendid achievement. It exceeds in boldness and brilliancy all other operations of the war. It will be memorable in military history, and will be admired by future generations." On April 12th, General Pope and his entire command embarked on transports and steamed down the river, in company with the gunboat fleet. The force arrived in front of Fort Pillow on the 14th. In a few days, before reconnoitring was completed, Pope was ordered to report with his whole command, except two regiments to be left with the gunboats, to General Halleck at Pittsburg Landing.
