Frederick now saw that artillery was the superior arm, and proved it at Rossbach (q.v.) and at Leu then (q.v.) in 1757. In these two battles the demoralization of the enemy was handed over from the infantry to the gunner. Not only did Frederick realize that artillery should prepare the in fantry attack, but that it should search out the enemy where the terrain concealed him, conse quently he increased his howitz ers to one-third of his total guns, and massing them brought them against the defender's flank. Leuthen is probably the finest example of the Frederician tac tics. The Austrians, less well drilled, deployed, but he marched straight forward deploying his advanced guard only. Then wheel ing the main body to the right he placed it at right angles to the enemy's left and deployed it in echelon in oblique order. The Austrians were fixed, since they were unable to manoeuvre. On their left flank, now in confusion through attempting to form a new front, Frederick converged the fire of all his guns. Under this fire his infantry advanced to the assault, and his cavalry manoeuvred on the rear of the enemy. At Torgau (q.v.) in 176o, one of his most daring battles, he separated his army, and whilst Zieten and his cavalry held the enemy's front, the bulk of his army took the Austrians completely in reverse.
Such were his battles, classical actions drawn from the study of classical history, for Leuthen was modelled on Leuctra (q.v.). In brief, his system is expressed in his favourite maxim—"To bring one's own strength against the enemy's weakness." Like Alexander he refused one wing and assaulted with the other, the refused wing acting as a reserve to that part of the line not used for the shock. The assaulting wing consisted of an advanced guard, an artillery mass, an infantry mass and a cavalry mass. When the enemy stood in the open his guns smote them, and when he sought shelter by ground his howitzers pounded him to pieces.
glamour of Frederick's great battles blinded the military eye; soldiers sought his secret in his drill and not in his ideas, and pre pared for themselves a rude awakening in the wars of the Ameri can Rebellion and the French Revolution.
Whilst backwoodsmen and redskins were picking off the British red-coats, and whilst Simcoe, Tarleton and Ferguson were striv ing their utmost to counter them by raising light infantry, the marechal de Broglie, in 1778, at the camp of Vaussieux carried out experiments in line and column, showing that the evolutions of the first were heavy and difficult, and of the second flexible and speedy. Mesnil Durand advocated massive columns, Guibert battalion columns. Then came the French Revolution, all tactical shibboleths were cast to the winds; cohesion disappeared, and man took to natural fighting, that is skirmishing, and though the Revolutionary armies, utterly lacking in discipline were frequently beaten, in 1794 an A.D.C. of the duke of York was compelled to acknowledge that "No mobbed fox was ever more put to it to make his escape than we were." Though in their first campaigns the French looked upon columns solely as reservoirs for skir mishers, it soon became apparent that skirmishers should be used for the act of distraction, and that columns should be used for the act of decision, artillery being employed to co-operate with the skirmishers. Thus was re-established the tactics of the successive employment of arms.
