Warriors of God: Richard the Lionheart and Saladin in the Third Crusade

Tidbits:

Richard's armor was so good that the arrows shot at him just stuck and didn't penetrate.  He had so many arrows stuck to him in some battles that he looked like a pincushion, and the Arabs began to believe he was unkillable.

In one battle, Richards horse was killed out from under him, and he fought on on foot.  Saladin and his generals, seeing this, were appalled, and ordered a fine horse to be sent down to the king, as 'it was unfitting that such a noble king should not fight on a horse."
