SUPPLY PACK. 1 set of wheelwright's stores. 1 set of saddler's stores. 1 set of farrier's stores. SUGGESTED ORGANIZATION AND EQUIPMENT. The detailed exercise and tactics for mountain-batteries differ slightly in different military services, but the following general directions conform to the normal condition and will serve for the organization of temporary mountain-batteries. For packing, each piece complete requires four mules. For the service of each gun seven men are required, of which three fight the gun in action and four serve as mule-drivers and reserves. A full battery consists of six pieces in time of war and four in time of peace, and should comprise, in addition to the equipments of a single piece, one field-forge, with transport-mule and driver; two transport-boxes, containing farrier's, carpenter's, and saddler's tools, with transport-mule and driver (one spare wheel packed on this mule); one spare carriage complete, with transport-mule and driver; ammunition-boxes, containing small-arm ammunition, with transport-mule and driver; twelve ammunition-boxes containing reserve-gun ammunition, with three transport-mules and drivers. The battery should be organized into platoons under lieutenants, each platoon consisting of a section under a sergeant. Each section (the personnel and material of one gun) should consist of the chief of section, gun detachment (one corporal and six privates), and extra drivers and spare men. If there be but one ammunition-mule to a section, the number of men would be reduced to six. The first sergeant should command the ordnance-mules not with the first line, viz.: ammunition, spare carriage, blacksmith's and wheelwright's tools, relief. He is assisted by the stable-sergeant. The second lieutenant commands the pack-train, and is assisted by the quartermaster-sergeant. The commissioned officers, first sergeant, quartermaster-sergeant, stable-sergeant, and trumpeters should be mounted on horses; the blacksmith, wheelwright, and cooks, on mules. Officers, sergeants, and trumpeters should be armed with pistols; all enlisted men other than sergeants and trumpeters, with carbines. In line there should be an interval of twelve yards between sections. The positions of the captain and lieutenant, and first sergeant and chiefs of section, are the same as in a field-battery, both in line and column. The mules of a section are in the following order: carriage-mule, gun-mule, and ammunition-mules with the distance of a yard between them, and in column with a distance of two yards between sections. The gunner is near the right flank of leading mule; Nos. 1 and 2 are similarly placed with respect to the second and third mules. The drivers are on the left and opposite the heads of their mules.
