Plymouth harbor destroyed by???

[laurencius]

I followed an aircraft carrier and its seven escorts into Plymouth harbor. I snuck around and saw a normal pleasant harbor filled with docked ships. I decided it was too risky to go into shallow waters for that carrier, so I went back out to deeper waters hoping to get the carrier later.

I returned the next night to Plymouth to see if the carrier was there, but instead of the pleasant harbor I saw a harbor in flames. The harbor was littered with burning, sinking, ships. The only thing afloat were the destroyers just outside of the harbor.

Anyone ever see something like this? What could have sunk all those ships?
