Frederick the Great, however, was the first to initiate true Cavalry Tactics. He forbade any firing from horseback, formed his Cavalry in two ranks, and trained them to charge boot to boot in long lines of scores of Squadrons. He insisted on high speed over long distances, and adopted the plan of charging in three lines--the first of Cuirassiers, the second of Dragoons as a support, and the third in columns to protect the flank. The training and tactics of Frederick’s Cavalry have never been improved on, and are still the model for shock action. Frederick’s Cavalry was organized, like that of Gustavus, in Troops of 70 men, of which two, or, later, four smaller ones as in Europe to-day, formed a Squadron. The Regiment had 5 Squadrons, as it still has in Germany, although the fifth now becomes the depôt of the Regiment on mobilization. LIGHT HORSE During the Seven Years’ War, Austria made good use of a screen of _light troops_, both Horse and Foot, in front of her armies. Her Light Horsemen had been very serviceable in the Thirty Years’ War in the previous century, and had been constantly used since in fighting the Turks. These horsemen were irregular troops from Hungary, where they had been raised since the sixteenth century under the name of _Hussars_. They wore the national dress of Hungary, which Hussars have retained ever since they were imitated by Frederick during the Seven Years’ War, and in other armies later. _Lancers_ were similarly copied everywhere from the Polish Light Cavalry, clothed in their national costume, who joined Napoleon’s service in 1807. The lance, which had not been used since the early sixteenth century, was then reintroduced, and has since held its own, and even won ground in Germany. The British adopted Lancers after their experience against Napoleon’s Polish Lancers at Waterloo. The Prussians called them _Ulans_, from the Polish, while other nations adopted the French word _Lancier_, from the Late Latin _lancearius_ (_lancea_, a _lance_). British Light Cavalry began in the eighteenth century, in the Light Troops of the Dragoon Regiments, soon detached to be grouped into Light Dragoon Regiments, which, early in the nineteenth century, were changed to Hussars. After firing on horseback had been stopped by Frederick, Cavalry discarded the firearm until the close of the century, when the French Light Horse of the Revolutionary armies received a short musket, called by its old name of _carbine_, which became the universal Cavalry firearm for use on foot. But Heavy Cavalry had no firearms for years; even in the Prussian Army of 1870 only Light Cavalry were armed with the carbine. Cavalry Regiments were first brigaded during the eighteenth century, but had no higher organization. The Brigade formed one of the lines of Cavalry on each wing of the Army. Cavalry Divisions were first formed by Hoche in 1793, and were adopted by Napoleon, who extended the idea later to creating Cavalry Corps of two or more Divisions.
