In the matter of drill there was little or no change. The front was still increased or diminished by the doubling of ranks and of files, and the file still consisted of six men. The reduction of the numbers of pikemen, however, greatly increased the homogeneity of the infantry and contributed not a little to simplify its movements. Moreover, although the file might consist of six men, it is not likely, considering how far the musket and bayonet had superseded the pike, that the formation for action was greater than three ranks in depth. The platoon is not mentioned in the drill books, the probable reason being that it was not favoured by the French School, in which Charles and James had both of them received their training. But for this, there is every reason to suppose that the army encamped on Hounslow Heath would not have been found behind the times in the matter of exercise and equipment if it could have been transported without change to the field of Blenheim. Of the artillery there is still little to be said. Until 1682 gunners seem to have enjoyed their original distribution into small, independent bodies, in charge of the various scattered garrisons. Even such small organisation as appeared in the New Model seems to have been lost, and field-guns appear to have been told off to battalions of infantry, or to have been worked by such of the escort of fusiliers as had been trained by the few expert gunners. The artilleryman had long looked upon himself as a superior mortal,[226] but in 1682 he was brought under the Ordnance, subjected to military discipline, and regularly exercised at his duty. The time was not far distant when the organisation of the gunners was to be improved. Of engineers I can say no more than the few details already given when describing the Ordnance Office and the fusiliers.
