The artillery should never be placed in such a situation, that it can be taken by an enemy’s battery obliquely, or in flank, or in the rear; unless a position under these circumstances, offers every prospect of producing a most decided effect, before the guns can be destroyed or placed _hors de combat._ The most elevated positions are not the best for artillery, the greatest effects may be produced from a height of 30 or 40 yards at the distance of about 600, and about 16 yards of height to 200 of distance. Positions in the rear of the line are bad for artillery, because they alarm the troops, and offer a double object to the fire of the enemy. Positions which are not likely to be shifted, but from whence an effect may be produced during the whole of an action, are to be preferred; and in such positions a low breast work of 2 or 3 feet high may be thrown up, to cover the carriages. Artillery should never fire against artillery, unless the enemy’s troops are covered, and his artillery exposed; or unless your troops suffer more from the fire of his guns, than his troops do from yours. Never abandon your guns till the last extremity. The last discharges are the most destructive; they may perhaps be your salvation, and crown you with victory. The parks of artillery in Great Britain are composed of the following ordnance: 4 medium 12 pounders; 4 desaguliers 6 pounders; and 4 light 5¹⁄₂ inch howitzers. The following is the proposed line of march for the three brigades when acting with different columns of troops, as settled, in 1798. 12 Pounders. | 6 Pounders. | Howitzers. ----------------------+----------------------+---------------------- 4 Guns. | 4 Guns. | 4 Howitzers. 8 Ammunition Waggons.| 4 Ammunition Waggons.| 8 Ammunition Waggons. 1 Forge Cart. | 1 Forge Cart. | 1 Forge Cart. 1 Store Waggon, with | 1 Store Waggon. | 1 Store Waggon. a small proportion | | of stores and spare| | articles. | | 1 Spare Waggon. | 1 Spare Waggon. | 1 Spare Waggon. 1 Waggon to carry | 1 Waggon for bread | 1 Waggon with bread bread and oats. | and oats. | and oats. 2 Waggons with | 2 Waggons with | 2 Waggons with musquet ball | musquet ball | musquet ball cartridges. | cartridges. | cartridges. -- |-- |-- 18 Total. |14 Total. |18 Total. 2d.
