Well, my Caelian friends, I would not use the term backstab, instead I would use fire a few thousand bolts into your very hearts. Plus you bird people where never good in counting things. There are five medium sized armies marching upon you, and an please take the advice that mammoths tend to be a lot happier if they actually get something to EAT. When our crossbowmen slew 100+ starving mammoths, it was a salvation for both parties.
P.S.: This is indeed a very fun game.
