Ninth.—As fast as the Thirteenth army corps advances, the Seventeenth army corps will take its place; and it, in turn, will be followed in like manner by the Fifteenth army corps.

Tenth.—Two regiments from each army corps will be detailed by corps commanders, to guard the lines from Richmond to New Carthage.

Eleventh.—General hospitals will be established by the medical director, between Duckport and Milliken’s Bend. All sick and disabled soldiers will be left in these hospitals. Surgeons in charge of hospitals will report convalescents as fast as they become fit for duty. Each corps commander will detail an intelligent and good drill officer, to remain behind and take charge of the convalescents of their respective corps; officers so detailed will organize the men under their charge into squads and companies, without regard to the regiments they belong to; and in the absence of convalescent commissioned officers to command them, will appoint non-commissioned officers or privates. The force so organized will constitute the guard of the line from Duckport to Milliken’s Bend. They will furnish all the guards and details required for general hospitals, and with the contrabands that may be about the camps, will furnish all the details for loading and unloading boats.

Twelfth.—The movement of troops from Milliken’s Bend to New Carthage will be so conducted as to allow the transportation of ten days’ supply of rations, and one-half the allowance of ordnance, required by previous orders.

Thirteenth.—Commanders are authorized and enjoined to collect all the beef cattle, corn and other necessary supplies on the line of march; but wanton destruction of property, taking of articles useless for military purposes, insulting citizens, going into and searching houses without proper orders from division commanders, are positively prohibited. All such irregularities must be summarily punished.

Fourteenth.—Brigadier-General J. C. Sullivan is appointed to the command of all the forces detailed for the protection of the line from here to New Carthage. His particular attention is called to General Orders, No. 69, from Adjutant-General’s Office, Washington, of date March 20, 1863.

By order of

MAJOR-GENERAL U. S. GRANT.

McClernand was already below on the Mississippi. Two of McPherson’s divisions were put upon the march immediately. The third had not yet arrived from Lake Providence; it was on its way to Milliken’s Bend and was to follow on arrival.

Sherman was to follow McPherson. Two of his divisions were at Duckport and Young’s Point, and the third under Steele was under orders to return from Greenville, Mississippi, where it had been sent to expel a rebel battery that had been annoying our transports.

It had now become evident that the army could not be rationed by a wagon train over the single narrow and almost impassable road between Milliken’s Bend and Perkins’ plantation. Accordingly six more steamers were protected as before, to run the batteries, and were loaded with supplies. They took twelve barges in tow, loaded also with rations. On the night of the 22d of April they ran the batteries, five getting through more or less disabled while one was sunk. About half the barges got through with their needed freight.

When it was first proposed to run the blockade at Vicksburg with river steamers there were but two captains or masters who were willing to accompany their vessels, and but one crew. Volunteers were called for from the army, men who had had experience in any capacity in navigating the western rivers. Captains, pilots, mates, engineers and deck-hands enough presented themselves to take five times the number of vessels we were moving through this dangerous ordeal. Most of them were from Logan’s division, composed generally of men from the southern part of Illinois and from Missouri. All but two of the steamers were commanded by volunteers from the army, and all but one so manned. In this instance, as in all others during the war, I found that volunteers could be found in the ranks and among the commissioned officers to meet every call for aid whether mechanical or professional. Colonel W. S. Oliver was master of transportation on this occasion by special detail.

*Colonel Ellet reported having attacked a Confederate battery on the Red River two days before with one of his boats, the De Soto. Running aground, he was obliged to abandon his vessel. However, he reported that he set fire to her and blew her up. Twenty of his men fell into the hands of the enemy. With the balance he escaped on the small captured steamer, the New Era, and succeeded in passing the batteries at Grand Gulf and reaching the vicinity of Vicksburg.
