Polish Post Office (Danzig)

The Polish Post Office (Poczta Polska) in the Free City of Danzig (modern day Gdańsk) was created in 1920 and operated until the German invasion of Poland that marked the beginning of World War II.

[2] In 1930 the "Gdańsk 1" building on Hevelius Platz (square) in the Danziger Altstadt (Old Town) became the primary Polish post office, with a direct telephone line to Poland.

[citation needed] As tensions between Poland and Germany grew, in April 1939 the Polish High Command detached combat engineer and Army Reserve Sublieutenant (or 2LT) Konrad Guderski to the Baltic Sea coast.

With Alfons Flisykowski and others, he helped organize the official and volunteer security staff at the Polish Post Office in Danzig, and prepare them for eventual hostilities.

[3] The Polish defence plan assigned the defenders the role of keeping Germans from the building for 6 hours, when a relief force from Armia Pomorze was supposed to secure the area.
