To return to the development of light troops in the British army. In 1782 the light companies of nine regiments were assembled in camp at Coxheath, Kent, and, together with two battalions of infantry and two regiments of light dragoons, were practised in what was termed the "Dundas Exercises," which were being tried for the first time. A year or two later, Dundas visited the Prussian manœuvres, obtained some fresh ideas, and then published his monumental work, which eventually became the first drill-book authorised to be used in the British army. Dundas, however, had very little new to say about light troops, and his exercises were practically on the Continental model. In 1794 Sir Thomas Graham[43] (afterwards Lord Lynedoch) raised a regiment (which was numbered the 90th), and had it equipped and drilled as a light infantry corps, though it was not recognised officially as such for another eleven years. It was in the above year that Moore was working with Corsican troops in the field, and he always considered the Corsicans the best light infantrymen in the world, although he acknowledged that they lacked the discipline necessary for holding their own against highly-trained troops. In 1798 Howe[44] again came to the front, and superintended the training of a brigade of all arms, assembled on the Essex coast, in his light drill. Lastly, in 1800, H.R.H. the Commander-in-Chief ordered the assembly at Horsham of a temporary corps, for the purpose of training a body of men in the use of the rifle, fourteen regiments being called upon to furnish thirty privates and a proportion of officers and non-commissioned officers. After the summer training, these men were moved to Blatchington, and were then formed into the Rifle Corps (95th),[45] for whom Colonel Coote Manningham and Lieutenant-Colonel the Hon. W. Stewart drew up the famous 'Regulations for the Rifle Corps,' published in 1801. The methods of training these riflemen were very similar to those employed in training temporary light infantry corps composed of the light companies of regiments, except in so far as the superior range and accuracy of the rifle over the flintlock musket altered the conditions of the attack and defence.
