A 13th century paring of the Mamluk Sultanate against the Mongol Ilkhanate using Lion Rampant wargame rules.
The two large cavalry forces faced off against each other on one flank, the infantry on the other. The mounted Mamluks eventually got the better of their opponents, even though they lost their commander. Likewise the Mamluk infantry was victorious, primarily due to their superior archery.
This is a very colourful period, with interesting troop types, little gamed by wargamers.
The Osprey rules were probably tested to their limit in this game, as they aren't really intended for larger battles, such as this. The shooting did appear to be overly powerful, which skewed the game somewhat. That said, everyone had fun, which is the main thing.
