Yes baron, you managed to combat an opponet that didn't contest the sea. Bad news for him, good news for you.
However, I'm really not all that impressed with your (and his) insistence on sending massive amounts of troops against citadels and fortifications.
I'd rather would have seen you attack his weak side to the north instead of playing wall games over there. Nothing was accomplished by skirmishing like that. You could have wiped out lots of villagers had you attacked to the north while not losing as many units.
