What a day...We met a Bretonian Gunboat in New London, it died.
Then it mysterically showed up again, fired on us and fled.
We then moved on to Dublin, where we killed a Bounty Hunter Bottlenose.
After that, the previously destroyed Gunboat showed up again with a friend, the friend fled, our friend died (again).
While we fought the Bretonian Gunboat, the Bottlenose showed up again and attacked us, guess what happened? It exploded again.
That'd be four Gunboat kills then.
