11. How is the ammunition which cannot be transported by the batteries carried? With the park; in caissons, or in store wagons. [Sidenote: 43]] 12. Do any other carriages and stores form part of the Field-Park? Yes; spare gun-carriages, one to each field-battery, _Traveling Forges_, } _Battery-Wagons_, } one or more of each. _Spare spokes_, 50 to each battery, } _Spare fellies_, 20 to each battery, } in store wagons. _Spare harness_, } in } _Horse-shoes and nails_, } boxes. } Gunpowder, saltpetre, sulphur, charcoal, laboratory paper, cannon-primers (percussion and friction), fuzes and plugs for field-service, stuff for cartridge bags, woollen yarn, cotton yarn, glue. 13. Are any other pieces ever used for field service? Yes: sometimes the 12 and 18-pdr. siege guns, and the 8-in. siege howitzer. 14. For what particular service are these different pieces most suitable? The siege pieces for batteries of position; the 12-pdr. battery, for following the movements of infantry, and the 6-pdr. battery for those of cavalry. =NOTE.=—These siege pieces should be placed on the weakest points of a line, and on heights which either form a key to the position, or from whence the greatest and longest continued effect may be produced. 15. What are the peculiar advantages of Horse-Artillery? Possessing, from their lighter construction and mounted detachments, much greater locomotive powers than other field batteries, they are especially adapted for following the rapid evolutions of cavalry, for sudden attacks upon particular points, and for supporting the advance or covering the retreat of an army. [Sidenote: 44]] 16. How is a field gun mounted? Upon a four-wheel carriage, which answers for its transportation as well as for its service, similar to a siege carriage, but lighter, and the limber carrying an ammunition chest. 17. Where should a battery be placed before the commencement of an action? As much as possible under cover, by taking advantage of banks, hollow-ways, buildings, woods, &c. 18. Is if advisable to move a battery at once into position in the field? No; but if unavoidable, it should be masked as much as possible until ordered to open its fire. 19. How should a battery be masked? If practicable, by covering it with cavalry, in preference to infantry, as the former does it more effectually, and is sooner moved out of the way. 20. In commencing an action, how should the fire of a battery be directed? When the enemy is in line, the fire should be directed over the whole line, and not upon the real points of attack; but when in column, ready to advance, it should be concentrated upon the real points of attack. 21. How should batteries be placed in relation to the troops with which they are acting?
