On the eve of World War II, the Second Polish Republic faced diplomatic pressure from Nazi Germany, Soviet Union, and revisionist neighbors like Nazi Germany and Third Reich. Mobilization orders issued by Edward Rydz-Śmigły and political directives from President Ignacy Mościcki and the Polish government-in-exile attempted to implement plans tied to the French–Polish alliance and guarantees from United Kingdom and France (French Third Republic). Prewar units included formations raised from Polish Legions (World War I), cadres influenced by veterans of the Polish–Soviet War, and officers trained at institutions such as the Wyższa Szkoła Wojenna.
Polish Armed Forces in the September 1939 Campaign
During the Invasion of Poland, commanders like Edward Rydz-Śmigły and generals of armies such as Armia Poznań and Armia Warszawa confronted German formations including the Heeresgruppe Nord and Wehrmacht panzer divisions. Battles at Łódź (1939), Bzura, Westerplatte, and Wieluń exemplified resistance alongside the defense of Warsaw (1939 Siege). The Soviet invasion of Poland (1939) complicated frontlines after the Molotov–Ribbentrop Pact, leading to capitulation of organized forces and widespread internment in Soviet Union and Germany.

Polish forces fought in the Battle of France (1940), the Battle of Britain, and later in campaigns under 15th Army Group in the Italian Campaign including Battle of Monte Cassino where the Polish II Corps under Władysław Anders earned repute. Armoured formations led by Stanisław Maczek distinguished themselves in the Normandy landings and the Battle of Falaise.
Polish Armed Forces in the East and Soviet-aligned units
After the Sikorski–Mayski agreement and later diplomatic breakdown following the Katyn massacre revelations, Polish soldiers released from Soviet Gulag camps formed the Anders' Army which later evacuated to the Middle East campaign; meanwhile Soviet authorities created the Polish Armed Forces in the East under Berling such as the 1st Tadeusz Kościuszko Infantry Division and the 1st Polish Army integrated with the Red Army. These units fought in operations including the Vistula–Oder Offensive and the Battle of Berlin, while political organs like the Polish Committee of National Liberation and personalities such as Bolesław Bierut shaped their allegiance.
Home Army and Underground Military Organizations
The Home Army (Armia Krajowa) emerged from structures of prewar resistance linked to Government Delegate's Office at Home and leaders like Tadeusz Bór-Komorowski coordinated clandestine units, intelligence networks associated with Secret Police and sabotage operations against German occupation. Major actions included Operation Tempest and the Warsaw Uprising of 1944, with contacts to Polish intelligence providing material to allies during events such as the Enigma decrypts exploitations. Other organizations included Armia Ludowa, National Armed Forces (NSZ), and partisan detachments operating in regions like Białystok, Lublin, and Kresy.
