i know the best tactic :) choose german conquer france and then passage between ur kingdom and england then betwen u and spanish/moors then save money and buy 3 trade researches then the cost removing one then use bug and buy all researches and change ur forces to 5 (or more if u want to waste units) teutonic knights deploy 1 in one line and u should win even hardest battles (i defeated 95 with half of cavalry and half of militas and 1 general while loosing 1 knight)
