Hmm, we should now demand they withdraw their settler from the sacred jungle and refrain from settling there for some number of turns. Pikes are obviously bad news for our attackers. Escorting a settler with 5 pikes indicates they see some land they really want to own. This is almost certainly the reason they had no gold on hand, they upgraded spears to pikes en masse. If they had had the foresight to keep a pike at home it would have been a much different story. Can we lure the barbs toward the TNT positions?
