La invasión de Polonia

They do not know that the greatest war in history is about to break out and that everything will start with the invasion of their homeland. The German invasion of Poland has been considered the trigger for World War II. It was announced by Adolf Hitler in a speech, days before the start of the war, in which he made his intentions clear: "Annihilation of Poland in the first place [...] Show no mercy. Act brutally".

In just under a month, the country was militarily conquered and divided between Germany and the USSR, based on the secret clauses of the Non-Aggression Pact, signed in August 1939.
