How was Danzig taken by Germany?

/kloc-in the early morning of September, 2000, two units of the Northern Army encountered heavy fog while taking action. Although this kind of weather helps to cover the operation, it also creates a chaotic situation in which troops fire at each other. The 4th Army directly pushed eastward from Pomerania to block the Polish corridor, while the 3rd Army split into two roads, attacking southwest (meeting the 4th Army in the Polish corridor) and advancing southward to attack the Polish capital. Further north in the Polish corridor, although Poland's powerful military forces continued to resist along the Baltic coastline, the Polish army in the Ze region hardly made effective resistance. Danzig was quickly occupied by a German infantry brigade.
