This is a common problem in history texts. You got to go to the other side. But I did read this pre WW-II British review of WW-I German Raiders and it makes point that the raiders that held up in some bay/neutral port for provisions were always caught, but those who practice recoiling at sea, stayed on the move and survived!John T wrote: ↑23 Mar 2020 22:59No, not according to German sources.

Went and pulled a copy of a book I forgot i had called Under Three Flags by Geoffrey Jones. It's a history of the Nordmark, Altmark, Ermland and Dithmarschen. It describes the refueling method used and also contains more pictures of KM vessels refueling as well as U-Boats. Again the method used is as shown in the pictures above. The vessels manoeuvre stern to bow, then they hold stationary postion while hoses are connected and fuel exchanged. They do not do as the Allies did and proceed underway to replenish. The method the KM used required near perfect weather conditions as well so there are cases of resupply taking three days in some cases because the seas were too rough.
And what sources did the author use?
I am always a bit skeptical of books about Germany in ww2 written by Anglo-Saxons.
Too much was too biased by wartime propaganda even into the seventies.
What about reading K G Lochners Als das eis brach page 20ff ?
That's a German source from a German author who read the German war diaries and Captain Daus report on refueling at sea.
In short, it confirms Glenns source.
Altmark devised a method to tow Graf Spee and transferred stores and fuel and lowest speed, but still at speed.
So they could do that in more adverse weather than just drifting in dead calm,
How do you expect two very different ships that catch the wind differently, keep at a fixed distance long enough to refuel?
But if you need photographic evidence out of suppression technique, I can't provide it.

If they could refuel a raider via coaling, while underway , I don't see why it could not be practiced in WW-II with tankers. KM had access to scores and scores of such tankers through the war and I recall some of the older pre Dithmarschen tankers also conducted refueling at sea.
