wow.
a great commander knows what to do,
i know how but i will not tell you lol,

look at the map
figure out which parts are less defended,
and most vunerable to those swift horsed archers are

you should always have at least ten villagers, btw.

the best way to fight is conquer the enemy is to flank them.
get a good showing of troops and force your way close to a settlement, and have your villagers construct barracks to keep renforcments close.

last bit of advice, always have a strong calvery,
and never leave your base empty of at least 5 mounted units.

good luck.
