most important element, and one not easily mastered, was to stay in one line with fixed spaces while accelerating and having the maximum speed at impact. Often knights would come in several waves, with the first being the best equipped and armored. The lance as a primary weapon pierced the enemy. If an enemy soldier was hit in full gallop by a knight's lance couched under the armpit, he was thrown backwards with such a momentum that he knocked over several of his compatriots, and was more often than not, killed; in some cases, the lance would even skewer the man and kill or wound the soldier behind him. The heavy lances were dropped after the attack and the battle was continued with secondary weapons (swords, battle-axes, war-hammers, or maces). The Persians deployed their cataphracts in mixed formations with light archers in the rear ranks, supporting the charge with arrows. Mongolian heavy cavalry improved upon the charging effect by attaching hooks to their lances to take enemies down when bypassing. Usually, employed a two-ranks deep formation of heavy cavalry charging the enemy. They were supported by three ranks of light cavalry, delivering rapid closeup shots with heavy armour-breaking arrows. Chinese and Japanese cavalry often used polearms. Both handled their primary weapons in the two-handed Asian style. This method of charging attack was very effective, but it depended very much on favourable ground on the chosen battlefield. Many knights during Medieval battles fought on foot. Attacks would be carried out on horseback only under favorable conditions. If the enemy infantry was equipped with polearms and fought in tight formations it was not possible to charge without heavy losses. A fairly common solution to this was for the men-at-arms to dismount and assault the enemy on foot, such as the way Scottish knights dismounted to stiffen the infantry schiltron or the English combination of longbowmen with dismounted men-at-arms in the Hundred Years' War. Another possibility was to bluff an attack, but turn around before impact. This tempted many infantrymen to go on the chase, leaving their formation. The heavy cavalry then turned around again in this new situation and rode down the scattered infantry. Such a tactic was deployed in the Battle of Hastings (1066). A further improvement of fighting ability was the use of well-armed infantry reserves during knightly battles on horseback. After some time, the battle would often split into
