Nihti
Recruit

Lance should be shatter to pieces to prevent rider to fall down from mount. After that infantry formation is broke and mounted warriors start use melee weapons from horseback against scattered enemy soldiers.
so even lance is broken or dropped after initial charge it could be not used again. Only shorter spear can be used against infantry from horseback with out losing grip to weapon. Lance was primarily used against spears at infantry formation longer because longer reach. Lance was single use weapon. When shorter spear impales footman, and horse is moving fast it will go through shield and armor, just like lance, but spear is possible to recover from footman and use again.
