I cannot believe it!! An army of cavalries beated by one single enemy cavalry!! My last two cavalries of the army have lost against the one-redlined attacking cavalry! Anyway the AI strategy is really strange against an army. If the army is going around pillaging whatever it find, nobody cares. Only when the army conquers a city the AI attacks without stacking the units. In my actual AW game I've a lonely city in the enemy continent with many artilleries and 3 army of cavalries. It's funny to see how many units the AI can lose without make any damage!
