Danzig is German for the Polish, Gdansk, not Kaliningrad.
Konigsberg = Kaliningrad. Correct.
FReegards!
Read thou 20th century history of Danzig. In that regard, (historical parallels) Kaliningrad IS Russian for Gdansk. Beside that, it had never, prior to the Yalta surrender by the West, been part of Russia. During the last months of WWII this historical city was completely destroyed by the Soviets, and was not rebuilt for decades afterwards, its remaining citizens, Poles, Lithuanians and Germans prevented from leaving it.
