Samurai,
It is currently turn 43. I'm looking at the map and can see 4 territories we need to dump. 2 are splitting the Knights and Vikings while 2 are pushed to far into Viking territory. We need to drop back from the north and just defend, some attacking helps defense there, keep them on Their toes. Keep the 4 territories nearest the Knight Stronghold and push that last one. We lose more assets attacking unneeded territories. This is almost like playing Risk so same rules apply.
