I have been reading Steven Runciman's excellent 3 volume history of the Crusades and in there are dozens of battles that I have never heard of and would like to recreate and play. For instance the Battle of Dorylaeum in the 1st Crusade - an army of French crusader knights on foot in the middle of the plain being pounded by two armies of Turkish horse archers - only to be rescued at the last minute by an army of 'Italian' crusaders coming down from the mountain pass. And the Bishop de Puy and a small company of knights appear behind the Turkish army and cause them to panic. How cool is that. Difficult to do as a custom battle though because you cannot one French army on the middle of the map and another Italian army on the edge. But you should be able to do this with the historical battles. I shall give the text editor a go and see how I get on.
Thanks
