Interesting, I never saw any Allied's air raid at Wilhelmshaven even in early years. Only saw them in 1943 and after at St.Nazaire, I bet Lorient and Brest get them too, but I play 7th Flotila mostly after I installed GW mod. Is this Allied air raid at Wilhelmshaven in mod or stock?
In GW, during 1940's when I sneaked into Bristol on several patrols to sink some nice stationary ships, German planes does arrived in mornings dropping bombs like the Blitz. I found it interesting that when one of them bomb on a large tanker and damaged it, I fired an eel to sink it, but my log doesnt showed that I have sunk that tanker even it didnt marked as sunk ship on either maps before my eel hit it and my periscope's notepad did registered that tanker before then tho.

I think I should be doing the typing or writing datas into my own logbook instead.
