The Europeans had fought Mongol type opponents before who could also ride circles around them. They were called Saracens and under an average commander the European could whack their arses. There is no reason why they could not do the same to the scruffy sheepherders.von Adler said:In addition, the Mongols are all mounted and can ride in cirkles around the English army should they choose so.
von Adler said:Mongol victory, ~9 000 English casualties, ~1 000 Mongol casualties.
Numbers from thin air. At the Battle of Arsuf in which the Crusaders were used cross bows instead of longbows and each side had 20,000 men in the same proportions as kw9751's scenario, albeit some of the Crusader infantry would be spearmen. The Crusader took 700 casualties and claimed to inflicted 7,000 on the Saracens, which was probably an over exaggeration. In this scenario We are therefore looking at 350 dead Europeans and 2,000 Mongols. The Europeans also have a morale advantage because the scruffy sheephers have no longer been shown to be invincible.
