You score an additional 25 victory points for every enemy standard bearer that was removed as a result of a successful pursuit move or slain in combat. If the enemy Battle Standard Bearer is slain under these circumstances, their death instead scores an additional 100 victory points.

Note that if a standard bearer of any kind is killed by a shooting attack, spell or anything else outside of close combat, these extra victory points are not scored (the enemy is assumed to whisk their prized banner away before your troops can get hold of it).
