It is now necessary briefly to sketch the organisation of the New Model. Beginning therefore with the infantry, the foot consisted of twelve regiments, each divided into ten companies of one hundred and twenty men apiece. As all the field-officers, even if they held the rank of general, had companies of their own, the full number of officers to a regiment was thirty: colonel, lieutenant-colonel, major, seven captains, ten lieutenants and ten ensigns. Each company included moreover two sergeants, three corporals, and one, if not two, drums.[165] The privates were divided as usual into an equal number of pikemen and musketeers: the weapons of officers being, for a captain, a pike; for a lieutenant, the partisan; and for an ensign, the sword. Since Skippon, a veteran of the Dutch school, was at the head of the infantry, it can hardly be doubted that the Dutch system of drill was preferred to the Swedish. Gustavus Adolphus, it must be remembered, was chiefly concerned with the Scots; while the contemporary drill books of the English prefer the teaching of Maurice of Nassau. It is therefore reasonably safe to conclude that the normal formation of the infantry of the New Model was not less than eight ranks in depth. The cavalry consisted of eleven regiments, each of which contained six troops of one hundred men. Here again every field-officer had a troop of his own, so that the full complement of officers to a regiment numbered eighteen, namely, colonel, major, four captains, six lieutenants, and six cornets. Three corporals and a trumpeter were included among the hundred men; and the admirable system which sorted each troop into three divisions, each under special charge of an officer and a corporal, was in full working order. In the matter of drill and tactics, the English cavalry was before rather than behind the times. The modified shock-action of Gustavus Adolphus had, under the influence of Rupert and Cromwell, been virtually superseded. The men indeed were still armed, according to the old fashion, with iron helmet and cuirass, and still carried each a brace of pistols as well as a sword; but they were instructed to trust to their swords in the charge, and to use their fire-arms only in the pursuit. Gustavus had formed his horse as a rule in four ranks; Rupert fixed the depth at three;[166] the Parliamentary officers went so far as to reduce the ranks to two, sacrificing depth to frontage, and trusting to speed, we cannot doubt, to overcome weight. Last and most daring innovation of all, they abolished the file as the tactical unit of the troop and substituted the rank in its place.[167] No better testimony to the improvement of English discipline could be found than this reduction in the depth of the ranks of cavalry. For once it may be said that the English horse stood in advance of all Europe.
