The park of artillery is generally placed in the centre of the second line of encampment, and sometimes in the rear line, or corps of reserve. In both places the muzzles of the guns are in a line with the fronts of the serjeants tents of the regiments of artillery and infantry. Some generals choose to place the park about 300 paces before the centre of the front line of the army. But let the situation be where it will, the manner of forming the park is almost every where the same, except that some artillery officers differ in the disposition of the carriages; others again divide the equipage as well as the guns into brigades, placing the first in the front line, the second in the next, and so on. However the most approved method, is to divide the whole into brigades, placing the guns of the first to the right of the front line, and their ammunition behind them, in one or more lines. The different brigades should be all numbered, as well as every waggon belonging to them. Example, 1st brigade, front line, No 1, 2, &c. 1st brigade, 2d line, No. 1, 2, &c. 2d brigade, front line, No. 1, 2, &c. and so of all the rest. This method prevents confusion in the forming and breaking up of the park, as also on a march: besides, according to the numbers, the stores therein contained are known. ARTILLERY--The proportion of artillery and ammunition necessary to accompany an army in the field, to lay siege to a fortified place, or to defend one, must depend upon so many circumstances, that it is almost impossible, in a work of this kind, to lay down any positive rules as guides on the subject: the following principles are drawn from the best authorities: 1st. ARTILLERY _for the Field_. FIELD Artillery is divided into _Battalion Guns_, _Artillery of the Park_, and _Horse Artillery_. The _Battalion Guns_ include all the light pieces attached to regiments of the line, which they accompany in all manœuvres, to cover and support them. The following kinds of field ordnance are attached to battalions of infantry, by different powers in Europe: French --two-- 4 Prs. per battalion. English --two-- 6 do. do. Danes --two-- 3 do. do. Austrians --three-- 6 do. do. Prussians --two-- 6 Prs. to a battalion in the first line. Prussians --two-- 3 Prs. to a battalion in the second line. Hanoverians --two-- 3 Prs. per battalion.
