[expand]The coordinated charge was culminating maneuver. The cataphracts formed line abreast or wedge formation, maintaining tight spacing and uniform alignment. The advance began at trot allowing formation maintenance, accelerating to canter then gallop as range closed, reaching maximum speed in final moments before impact. The timing was critical—too early acceleration exhausted horses before contact, too late meant insufficient momentum. The formation integrity mattered enormously—gaps allowed enemy to strike isolated riders, excessive crowding prevented effective lance use, proper spacing maximized impact while allowing weapon employment.
The target selection determined success or failure. The heavy cavalry sought vulnerable enemy points—flank formations, weakened sections, inexperienced units—where charge could break through rather than merely impact. The frontal assault against prepared heavy infantry in good order was potentially suicidal—the cataphracts could be stopped, lances could be broken by shield walls, and charges might fail leaving armored cavalry vulnerable to counterattack. The successful commanders used heavy cavalry decisively at crucial moments against carefully selected targets rather than squandering elite forces in frontal grinds against prepared positions.
The shock impact relied on multiple factors. The physical force of armored horse and rider moving at speed was substantial—the momentum transfer could knock infantry soldiers down, disrupt formations, create penetrations. The psychological shock was perhaps greater—the thundering approach of armored cavalry with lance points leveled was terrifying, and infantrymen who broke and ran were cut down during rout. The combination of physical violence and psychological terror made successful charge devastatingly effective, enemy formations collapsing more from fear than from casualties inflicted during initial contact.
The exploitation required follow-through. The initial charge broke formation, creating chaos and beginning rout. The pursuit during enemy flight multiplied casualties—the fleeing infantry were defenseless, the cavalry could ride down scattered opponents, and sustained pursuit destroyed enemy army rather than merely defeating it. The most successful heavy cavalry operations combined breakthrough with relentless exploitation, transforming tactical victory into strategic annihilation through determined pursuit of broken enemy.
