Polish High Command (1939) The Polish High Command in 1939 was the strategic and operational leadership structure directing the Polish Army during the Invasion of Poland by Nazi Germany and later the Soviet invasion of Poland. It encompassed senior figures from the Ministry of Military Affairs (Second Polish Republic), the Supreme Command (Poland), and theater commanders responsible for implementing prewar plans such as Plan Zachód. The High Command's decisions were shaped by interactions with political leaders from the Sanacja regime, the presidency of Ignacy Mościcki, and the cabinet of Felicjan Sławoj Składkowski.

Overview

The High Command combined operational, strategic and logistical functions across headquarters in Warsaw, Brześć and field commands near Kraków and Poznań. Its senior staff included officers from the Polish General Staff, the Inspectorate of the Armed Forces, and the Ministry of Military Affairs. Doctrine and planning referenced outcomes of the Treaty of Versailles, lessons from the Polish–Soviet War, and intelligence on Wehrmacht formations including the Heeresgruppe Süd and Heeresgruppe Nord. Relations with neighboring states such as Romania, Lithuania, and Czechoslovakia affected strategic calculus, as did expectations about support from France and the United Kingdom under the Anglo-Polish military alliance.

Organization and Key Figures

The High Command’s hierarchy centered on the Commander-in-Chief, Marshal Edward Rydz-Śmigły, supported by Chief of the General Staff General Wacław Stachiewicz and Deputy Chiefs including General Tadeusz Kutrzeba and General Władysław Bortnowski. Key Corps and Army commanders included General Józef Haller (honorary link), General Kazimierz Sosnkowski, General Mieczysław Smorawiński, General Franciszek Kleeberg, and General Władysław Langner. Staff branches interfaced with the Polish Air Force under Air Vice Marshal Stefan Pawlikowski, the Polish Navy leadership including Rear Admiral Jerzy Świrski, and the Border Defence Corps commanded by General Andrzej Przewłocki. Intelligence was provided by sections of the II Department and liaison officers to allies such as Charles de Gaulle’s French counterpart and British military attaches connected to Winston Churchill’s Admiralty and War Office networks.

Prewar Preparations and Doctrine

Prewar planning was framed by Plan Zachód and influenced by interwar debates among proponents of mobile defence and positional defence as theorized by Polish officers during the Polish–Soviet War and studies of the German rearmament. The High Command integrated lessons from the Spanish Civil War and assessments of Blitzkrieg concepts observed in German exercises. Logistics planning relied on rail corridors via Warsaw Railway Junction, mobilization timetables linked to the Cordon Sanitaire context, and stockpiles at depots in Łódź, Lwów, and Toruń. Political-military coordination involved the President of Poland and the Council of Ministers while diplomacy with France and United Kingdom sought guarantees under the Anglo-Polish alliance.

Mobilization and Operational Plans

Mobilization orders invoked the legal framework of the Sanation-era decree system and were implemented through regional military districts in Kraków Voivodeship, Lwów Voivodeship, Poznań Voivodeship and Warsaw Voivodeship. Operational plans allocated armies to defend the Vistula River line, the Hel Peninsula naval base, and key cities including Warsaw, Kraków, Lwów and Gdynia. Corps-level dispositions anticipated engagements against Heer panzer divisions and sought to interdict movements along the Silesian and Pomeranian corridors. Communication relied on telegraph lines to field headquarters and liaison with Armia Poznań, Armia Pomorze, Armia Kraków and Armia Łódź formations; contingency planning accounted for potential Soviet interference and refugee flows from Eastern Borderlands.

Actions during the September Campaign

During the September Campaign, decisions by the High Command directed counterattacks such as General Kutrzeba’s maneuver at the Battle of Bzura and defensive stands at the Siege of Warsaw, the Defense of the Polish Post Office in Danzig, and the Battle of Mokra. Coordination with the Polish Air Force resulted in sorties against Luftwaffe targets including engagements near Łódź and Częstochowa, while the Polish Navy executed operations from Gdynia and aboard destroyers such as ORP Błyskawica. The High Command issued evacuation directives sending units and government elements toward Romania and Hungary and to ports for potential Allied intervention. Rapid advances by Wehrmacht panzer groups, breakthroughs at Częstochowa and encirclements near Kämpfe forced reassignments; Soviet entry on 17 September precipitated collapse of organized fronts in the Kresy.

Aftermath and Reorganization

After capitulations and the fall of major garrisons, surviving commanders including General Władysław Sikorski and General Kazimierz Sosnkowski participated in the formation of the Polish government-in-exile in France and later in London. Elements of the High Command were reconstituted within the Polish Armed Forces in the West and the Polish Armed Forces in the East under Allied coordination, interfacing with the Free French Forces, British Expeditionary Force planners, and later with Soviet authorities amid the Tehran Conference and Yalta Conference geopolitical shifts. War crimes investigations referenced incidents such as the Katyn massacre while postwar military institutions evolved into branches of the Polish People's Army during the Provisional Government of National Unity period. The legacy of 1939’s High Command shaped commemoration at sites like the Warsaw Uprising Museum and influenced historiography by scholars connected to Józef Piłsudski’s military legacy.
