sell his commission in the dragoons, and at the same time to retain his rank in
the army. He afterwards exchanged his appointment for that of adjutant-general, and in 1781 he was promoted to the rank of colonel.
Shortly after the peace of 1783, Frederick king of Prussia having ordered a grand review of the whole forces of his kingdom, the attention of military men throughout Europe was attracted to a scene so splendid. Amongst others, colonel Dundas, having obtained leave of absence, repaired to the plains of Potsdam, and by observation and reflection on what he there saw, he laid the foundation of that perfect knowledge of military tactics, which he afterwards published under the title of "Principles of Military Movements, chiefly applicable to Infantry."
In the year 1790, colonel Dundas was promoted to the rank of major-general, and in the following year, he was appointed colonel of the 22nd regiment of infantry, on which he resigned the adjutant-generalship of Ireland.
Previous to the publication of general Dundas' work on military tactics, the military mameuvres of the army were regulated by each succeeding commander-in-chief; while even the manual exercise of the soldier varied with the fancy of the commanding officer of the regiment. The disadvantages attending so irregular a system is obvious; for when two regiments were brought into the same garrison or camp, they could not act together until a temporary uniformity of exercise had been established. To remedy these defects in our tactics, his majesty, George III., to whom general Dundas' work was dedicated, ordered regulations to be drawn up from his book, for the use of the army; and accordingly in June, 1792, a system was promulgated, under the title of" Rules and Regulations for the formations, field-exercises, and movements of his Majesty's forces; with an injunction that the system should be strictly followed and adhered to, without any deviation whatsoever: and such orders as are formed to interfere with, or counteract their effects or operation, are considered hereby cancelled and annulled." "The Rules and Regulations for the Cavalry" were also planned by general Dundas. It is therefore to him that we are indebted for the first and most important steps which were taken to bring the British army to that high state of discipline which now renders it the most efficient army in Europe.
At the commencement of the late war, general Dundas was put on the staff, and in autumn 1793, he was sent out to command a body of troops at Toulon. While on this service, he was selected to lead a force ordered to dislodge the French from the heights of Arenes, which commanded the town ; and although he succeeded in driving the enemy from their batteries, still the French were too strong for the number of British employed in the service, and he was ultimately driven back ; and Toulon being consequently deemed untenable, lord Hood judged it prudent to embark the troops and sail for Corsica. Soon after the expedition had effected a' landing in that island, some misunderstanding having arisen between general Dundas and admiral Hood, the former returned home.
General Dundas immediately returned to the continent, and served under the duke of York in Holland; and in the brilliant action of the 10th of May, 1794, at Toumay, he greatly distinguished himself. During the unfortunate retreat of the British army, which ended in the evacuation of the Dutch territory, general Dundas acted with such skill and great gallantry, and on the return of general Harcourt to England, the command of the British army devolved upon him. Having wintered in the neighbourhood of Bremen, he embarked the remnant of the British forces on board the fleet on the 14th of April, 1795,
and returned home.
