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 small work of this kind, to lay down any satisfactory rules as guides on the subject: the following principles are, however, 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 natures of field ordnance are attached to battalions of infantry, by different powers in Europe:
| French | two | 4 | Prs. | per | battalion. |
| English | two | 6 | ” | ” | ” |
| Danes | two | 3 | ” | ” | ” |
| Austrians | three | 6 | ” | ” | ” |
| Prussians | two | 6 | Prs. to a battalion in the first line. | ||
| ” | two | 3 | Prs. to a battalion in the second line. | ||
| Hanoverians | two | 3 | Prs. per battalion. | ||
The Artillery of the Park is composed of all natures of field ordnance. It is destined to form batteries of position; that is to say, to occupy advantageous situations, from which the greatest effect may be produced, in supporting the general movements of an army, without following it, like the battalion guns, through all the detail of its manœuvres. The park of artillery attached to an army in the field generally consists of twice as many pieces of different natures, varied according to the country in which it is to act, as there are battalions in the army. Gribauvale proposes the following proportion between the different natures of artillery for the park or reserve, viz. ⅖ of 12 Prs. ⅖ of 8 Prs. and ⅗ of 4 Prs. or reserve for battalion guns. In a difficult country he says, it may be ¼ of 12 Prs. ½ of 8 Prs. and ¼ of 4 Prs. and for every 100 pieces of cannon he allots 4 Howitzers; but this proportion of Howitzers is much smaller than what is generally given.
Horse Artillery.—The French horse artillery consists of 8 Prs. and 6 inch Howitzers.
The English of light 12 Prs. light 6 Prs. and light 5½ inch Howitzers.
The Austrian and Prussian horse artillery have 6 Prs. and 5½ inch Howitzers.
