two waves, the first wave should be 300 militia and the second wave should have 1 militia and over 20K archers, it seems like the more archers I send over 20K the lower my losses arewave 1 500 militia wave 2 25k archers and 1 militiaist wave 300 militia + 1 ballist 2nd wave 10,ooo archers 800 ballistas.
but your fleching has to be level 9
u will lose the entire 1st wave, it will take out the traps. there is no way around it, but better to lose militia then more expensive troops
if your fleching is not 9, or u use substitute troops youll have more losses
