I also advise, if possible, to make it so that it is impossible to camp a party right next to Banon and protect against all of the soldiers. Otherwise you could just have one party camp right at the start standing next to Banon, and walk wherever with an attack party without fear of repercussion. I can imagine a couple ways to deal with this, such as having a line of marked tiles at the top which the soldiers cannot cross or you lose (that is too large to camp with a party).
