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. _AMMUNITION for Field Artillery._ _A proportion of Ammunition and Stores for each Nature of Field Ordnance, viz. 1 Med. 12 Pr.[1]—1 heavy 6 Pr.—2 light 6 Prs. as they are always attached to Battalions of Infantry—and one 5½ inch Howitzer; according to the British Service._
