Yeah, thats right!
I spotted a trawler on map just north of Germany, in 1939.
I sailed on to sink it for fun. And thats when it happened!
I wanted to be a bit close to it so no shell would miss, so i plotted the course on the navigator map. Suddenly the WO reports a collision.
I changed the view to the bridge and i saw a big, red, unreported ship without flags
(The trawler had luxembourgish i think, the one with the red, white and blue horizontal stripes.) just next to the trawler.
I fired at it. No fires, no nothing before the massive explosion that cut it to two.
Anyone got any idea?
