Hmm, i must agree with above posts, but i observed, that A.I. is quite smarter than in normal.

I played HRE(again ) and my crusading army was attacked by three full stacks of egyptian soldiers. And they attacked in waves. They had superior general(6 stars in command if my memory is good, and few morale boosting virtues...horrible). I thought, that he will be in the first line of attack, and he actualy was....but not in my sight when his first line(composed of infantry crap) impacted into my lines. After very long and hard fight, my line beated off his first line, but they were to tired to search and destroy that enemy commander. And the second wave came to me and again, bloody and hard fight. My army was anihilated by the third wave, and the only my commander(having about 15-18 valour) and several feudal men at arms(with valour near 10) withdrawed from battle. On my side, not a single unit broke, they were all anihilated. And on muslem side was similar. They losses in each unit reached 70%-100% and fleeing units was rare sight.

I never seen that before, cos A.I. usualy not use superior numbers to his advantage.....he rather picks strongest units of infantry in the first wave, and general is near(as i may write from that day) always is with the first wave.
