He actually ended up losing all 30 of his troops, and his military score went down to zero. I sent him a message by wasting a bunch of gold and all of my troops to attack him back and looted 6 ships of goods from him.
Fucker was 2 hours away! LOL
He then mailed me back saying “Well, my town is a higher level than yours!” And at that point, 4 minutes later my town upgraded to his town level and I said “look again. You lose”
That was fun… 
OK! ALLIANCE?!
