Thanks for this reminder !
It should be noted perhaps, that the German fleet actually didn't "surrender" at this day, but
got "interned". Maybe sounding like nitpicking today, but very important back then.
There still had been not peace talks, so the fate of the fleet wasn't clear and the interned ships
actually didn't represent the whole fleet, just the most modern part of it. The dreadnoughts of
the Nassau and Oldenburg-classes still were in German harbours and so excluded from being
scuttled in 1919.
