This mission is almost the same as mission 1 only difference is that in here you'll meet wolves. All you need to do is to build few woodcutter huts and hunter posts to ensure food and wood supply. If the wolfs bothers you i recommend to use your lord (he is very strong but also if he'll die you'll lose this mission so be careful while using him in battle). After the first wood supplies arrives from woodcutter huts you should start to build a walls. After you'll complete walls and gather enough food you'll win.
