To win any death match with the Britons you must get about 40 longbow
men and about 10 trebuchets, change the longbow men's stance to stand
ground and attack (at the furthest range possible) with the trebuchets.
The enemies buildings will be under attack and the longbow men will
shoot at any enemy units coming out to attack. If there are to many
enemy units and your team is wiped out, then repeat this strategy until
victory. Remember it is always best to fortify your base first so you
don't have to worry about it being attacked while you are focusing on
something else.
