Invasion of PolandThe Invasion of Poland, also known as the September Campaign, Polish Campaign, War of Poland of 1939, and Polish Defencive War of 1939 (1 September – 6 October 1939), was a joint attack on the Republic of Poland by Nazi Germany, the Slovak Republic, and the Soviet Union; which marked the beginning of World War II. The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and the Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact.
Free City of DanzigThe Free City of Danzig (Freie Stadt Danzig; Wolne Miasto Gdańsk) was a city-state under the protection of the League of Nations between 1920 and 1939, consisting of the Baltic Sea port of Danzig (now Gdańsk, Poland) and nearly 200 other small localities in the surrounding areas. The polity was created on 15 November 1920 in accordance with the terms of Article 100 (Section XI of Part III) of the 1919 Treaty of Versailles after the end of World War I. In line with the treaty provisions, the entity was established under the oversight of the League of Nations.
Warsaw UprisingThe Warsaw Uprising (powstanie warszawskie; Warschauer Aufstand) was a major World War II operation by the Polish underground resistance to liberate Warsaw from German occupation. It occurred in the summer of 1944, and it was led by the Polish resistance Home Army (Armia Krajowa). The uprising was timed to coincide with the retreat of the German forces from Poland ahead of the Soviet advance. While approaching the eastern suburbs of the city, the Red Army halted combat operations, enabling the Germans to regroup and defeat the Polish resistance and to destroy the city in retaliation.
PomereliaPomerelia, also known as Eastern Pomerania, Vistula Pomerania, prior to World War II also known as Polish Pomerania, is a historical sub-region of Pomerania on the southern shore of the Baltic Sea. The designation of Gdańsk Pomerania, is largely coextensive with Pomerelia, but slightly narrower, as it does not cover the Chełmno Land (including the Michałów Land). Its largest and most important city is Gdańsk. Since 1999, the region has formed the core of the Pomeranian Voivodeship.

The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe, of the Wehrmacht, the German armed forces from 1935 to 1945.
