I found this on 19 January 1940 in grid AN95 heading to Willmeshaven.
First time I ever saw that thing.
Edit : This is the reason Two British DDs following him.
Edit No2 : Check the stern of the DD. He is on a mine laying operation. Their speed was 35 Kts
Edit No3 : And then the unexpected happened. The Luftwaffe attacked but the DDs even used their 5in guns and shot them down. The first time they showed up to help they messed things up!
