Fourth.—­The order of march to New Carthage will be from right to left.

Fifth.—­Reserves will be formed by divisions from each army corps; or, an entire army corps will be held as a reserve, as necessity may require.  When the reserve is formed by divisions, each division will remain under the immediate command of its respective corps commander, unless otherwise specially ordered for a particular emergency.

Sixth.—­Troops will be required to bivouac, until proper facilities can be afforded for the transportation of camp equipage.

Seventh.—­In the present movement, one tent will be allowed to each company for the protection of rations from rain; one wall tent for each regimental headquarters; one wall tent for each brigade headquarters; and one wall tent for each division headquarters; corps commanders having the books and blanks of their respective commands to provide for, are authorized to take such tents as are absolutely necessary, but not to exceed the number allowed by General Orders No. 160, A. G. O., series of 1862.

Eighth.—­All the teams of the three army corps, under the immediate charge of the quartermasters bearing them on their returns, will constitute a train for carrying supplies and ordnance and the authorized camp equipage of the army.

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.
