Poland had been invaded by Germany for over 4 years before the Allies’ landing. The resistance movement “Home Army”, one of the greatest in the world, was established in the Polish territory. It was ruled by the government abroad, in London. It was clear then that Poland was supposed to be liberated by the Normand Front, which was just being created, not by Balcan Front, as it was thought at the beginning. For the government it was obvious that Russian Army is the one to come and ”free” the country. Due to this fact, The government in London took steps to establish some diplomatic relationship with the USSR, as they were broken at the beginning of the war, and they ordered “Home Army” to support “Red Army” in the fight with the Germans.

Because of a not widely recognized fact that the Polish forces participated In military actions on the allies’ side, including the D- Day operation, there are mentioned a few considerable facto abort it, below. The Polish composed 4 consecutive armies outside the occupied Poland 1. In France in 1939 after Poland’s capitulation according to the decision of the Polish Exile Government in Anger.

The Polish Folk Army established in the USSR commanded by Gen. Z. Berling (I Tadeusz Kosciuszko Division) as the effect of Soviet Union policy to organize the Polish Army as the counterweight to the Polish Exile Goverment and its armies. This Army fought by the side of the Soviet Red Army. In the first phase of campaign of the Overlord Operation the Polish shipping units played a very important role. They supported the invasion sources from the water. These were the war ships: “Slazak”, “Krakowiak”, “Dragon” which kept on shooting the coast and “Blyskawica” and “Piorun” which protected the invasion fleet. Thanks to “Slazak” which was commended by commander R. Na³êcz- Tyminski made it possible that the British amphibian with tanks Shermans could reach the beach which was named before the Operation as the British Beach in Normandy-“Sword”. “Slazak” critically reduced the hidden in the nearby forest the German coast battery’s force.
