Władysław Sikorski

Sikorski was born in Tuszów Narodowy, Galicia, at the time part of the Austro-Hungarian Empire.[1] He was the third child in his family; his father was Tomasz Sikorski, a school teacher; his mother was Emilia Habrowska.[1] His grandfather, Tomasz Kopaszyna Sikorski, had fought and been wounded at the Battle of Olszynka Grochowska in the November Uprising, during which he received the Virtuti Militari medal.[2]

Sikorski in his youth

Sikorski attended the gimnazjum in Rzeszów (now Konarski's High School in Rzeszów) from 1893 to 1897, then transferred for a year to a Rzeszów teachers' college.[1] In 1899 he attended the Lwów Franciszek Józef Gymnasium, and in 1902 he passed his final high school exam there.[1] Starting that year, young Sikorski studied engineering at the Lwów Polytechnic, specializing in road and bridge construction, and graduated in 1908 with a diploma in hydraulic engineering.[1] In 1906 Sikorski volunteered for a year's service in the Austro-Hungarian army and attended the Austrian Military School, obtaining an officer's diploma and becoming an army reserve second lieutenant (podporucznik rezerwy).[3] In 1909 he married Helena Zubczewska, whom he met while at the high school in Lwów.[1][4] In 1912 they had a daughter, Zofia.[5] After graduation he lived in Leżajsk and worked for the Galician administration's hydraulic engineering department, working on the regulation of the San river, and later was involved in private enterprises related to construction, real estate and petroleum trade.[1][3][4]

During his studies at the Polytechnic, Sikorski became involved in the People's School Association (Towarzystwo Szkoły Ludowej), an organization dedicated to spreading literacy among the rural populace.[1] Around 1904–1905 he was briefly involved with the endecja Association of the Polish Youth "Zet", and then drifted towards paramilitary socialist organizations related to the Polish Socialist Party, which was intent on securing Polish independence.[3] He made contact with the socialist movement around 1905–1906 through the Union for the Resurrection of the Polish Nation (Związek Odrodzenia Narodu Polskiego).[3] In 1908, in Lwów, Sikorski—together with Józef Piłsudski, Marian Kukiel, Walery Sławek, Kazimierz Sosnkowski, Witold Jodko-Narkiewicz and Henryk Minkiewicz—organized the secret Union for Active Struggle (Związek Walki Czynnej), with the aim of bringing about an uprising against the Russian Empire, one of Poland's three partitioners.[3][4] In 1910, likewise in Lwów, Sikorski helped to organize a Riflemen's Association (the Związek Strzelecki), became the president of its Lwów chapter, and became responsible for the military arm within the Commission of Confederated Independence Parties (Komisja Skonfederowanych Stronnictwo Niepodległościowych, KSSN).[3][4] Having a military education, he lectured other activists on military tactics.[3]

Upon the outbreak of the First World War in July 1914, Sikorski was mobilized, but through KSSN influence he was allowed to participate in the organizing of the Polish military units, rather than being delegated to other duties by the Austro-Hungarian military command.[3] In the first few weeks of the war he became the chief of the Military Department in the Supreme National Committee (Naczelny Komitet Narodowy, NKN) and remained in this post until 1916.[3] He was a commissioner in charge of the recruitment to the Polish Legions in Kraków, choosing this role over the opportunity to serve in the Legions as a frontline commander.[3][6] On 30 September 1914 he was promoted to podpułkownik (lieutenant colonel), and soon after that he became the commander of a Legions officer school (Szkoła Podchorążych).[3][4] The Legions — the army created by Józef Piłsudski to liberate Poland from Russian and, ultimately, Austro-Hungarian and German rule — initially fought in alliance with Austria-Hungary against Russia. From August 1915 there was growing tension between Sikorski, who advocated cooperation with Austria-Hungary, and Piłsudski, who felt that Austria-Hungary and Germany had betrayed the trust of the Polish people.[3][6] In 1916 Piłsudski actively campaigned to have the Military Department of NKN disbanded.[6] In July that year, Sikorski was promoted to pułkownik (colonel).[4] Following the Act of 5th November (1916), Sikorski became involved with the Legions' alternatives, the Polish Auxiliary Corps and Polnische Wehrmacht.[6] In June 1917 Piłsudski refused Austro-Hungarian orders to swear loyalty to the Habsburg Emperor (the "oath crisis") and was interned at the fortress of Magdeburg, while Sikorski abandoned Polnische Wehrmacht and returned to the Austro-Hungarian Army.[6] In 1918, however, following the February Treaty of Brest-Litovsk and the battle of Rarańcza, Sikorski chose belatedly to side with Piłsudski, announcing solidarity with his actions, protesting against planned separation of Chełm Land from the planned Polish state, and thus soon joined Piłsudski in internment (he would be held in Dulfalva (Dulovo)).[4][6] Nonetheless, this was not enough to smooth the differences between him and Piłsudski, and these two major Polish leaders would drift farther apart in the continuing years.[4]

Sikorski in 1923

Despite their differences, Piłsudski praised Sikorski in his reports, recommending him for Chief of the General Staff and Minister of War positions; only generals Kazimierz Sosnkowski and Edward Rydz-Śmigły received better evaluations from him.[10] Sikorski was popular among many soldiers, and in politics, particularly appealing to Polish conservatives and liberals.[10] On 1 April 1921 Sikorski replaced general Tadeusz Jordan-Rozwadowski as the chief of the Polish General Staff.[10] Between 1922 and 1925 he held a number of high government offices. Based on his analysis, the Polish Council of Ministers adopted new foreign policy that would remain roughly unchanged until the late 1930s (preserving the status quo in Europe, and treating Germany and Russia as equal sources of potential threat).[10] On 12 December 1922 he issued a general order, stressing the need for the military to stay out of politics.[10] After the assassination of President of Poland Gabriel Narutowicz on 16 December 1922, the Marshal of the Sejm (Sejm being the Polish parliament), Maciej Rataj, appointed Sikorski prime minister.[10] From 18 December 1922, to 26 May 1923, Sikorski served as Prime Minister and also as Minister of Internal Affairs, and was even considered as possible President.[10] During his brief tenure as prime minister, he became popular with the Polish public and carried out essential reforms in addition to guiding the country's foreign policy in a direction that gained the approval and cooperation of the League of Nations and tightened Polish-French cooperation. He obtained recognition of Poland's eastern frontiers from the UK, France and the United States during the Conference of Ambassadors on 15 March 1923[11] He aided Treasury Minister Władysław Grabski's reforms aiming at curtailing inflation and reforming the currency, and supported ethnic minorities.[10] His government nonetheless lost support in the Sejm and resigned on 26 May 1923.[11]

From 30 September 1923 to 1924 he held the post of Chief Inspector of Infantry (Generalny Inspektor Piechoty).[11] From 17 February 1924 to 1925, under Prime Minister Grabski, he was Minister of Military Affairs and guided the modernization of the Polish military; he also created the Korpus Ochrony Pogranicza.[11] He worked actively to promote the cause of the Polish-French military alliance.[11] His proposal to increase the powers of the Minister of Military Affairs while reducing those of the Chief Inspector of the Armed Forces met with sharp disapproval from Piłsudski, who at that time was gathering many opponents of the current government.[4][11] From 1925 to 1928 Sikorski commanded Military Corps District (Okręg Korpusu) VI in Lwów.[11]

A democrat and supporter of the Sejm, Sikorski declared his opposition to Józef Piłsudski's May coup d'état in 1926;[11] however he remained in Lwów, refused to dispatch his forces, and played no significant role in the short struggle surrounding the coup.[4][11] In 1928 he was relieved by Piłsudski of his command, and while he remained on active service, he received no other posting.[11] That year also saw the publication of his book on the Polish–Soviet War, Nad Wisłą i Wkrą. Studium do polsko–radzieckiej wojny 1920 roku (At the Vistula and the Wkra Rivers: a Contribution to the Study of the Polish–Soviet War of 1920).[11] He would spend the following years studying military theory, publishing works on military theory, history and foreign policy.[11] His most famous work was his 1934 book Przyszła wojna – jej możliwości i charakter oraz związane z nimi zagadnienia obrony kraju (lit. War in the Future: Its Capacities and Character and Associated Questions of National Defense, published in English in as Modern warfare. Its character, its problems in 1943), in which he predicted the return of the maneuver warfare.[11][12] He wrote several other books and many articles, foreseeing, among other things, the rapid militarization of Germany.[4]

In due course, soon after he was relieved of his command, and as a semi-dictatorial Sanacja regime was established, Sikorski joined the anti-Piłsudski opposition.[12] Sikorski largely withdrew from politics, spending much of his time in Paris, France, and working with the French Ecole Superieure de Guerre (war college). Even after the death of Piłsudski in 1935, he was still marginalized, politically and militarily, by Piłsudski's successors.[12] In February next year, together with several prominent Polish politicians (Wincenty Witos, Ignacy Paderewski, and General Józef Haller) he joined the Front Morges, an anti-Sanacja political grouping.[12]

In the days before Poland was invaded by Germany in September 1939, and during the invasion itself, Sikorski's request for a military command continued to be denied by the Polish Commander in Chief, Marshal Edward Rydz-Śmigły.[12] Sikorski escaped through Romania to Paris, where on 28 September he joined Władysław Raczkiewicz and Stanisław Mikołajczyk in a Polish government-in-exile, taking command of the newly formed Polish Armed Forces in France.[12] Two days later, on 30 September, president Raczkiewicz called him to serve as the first Polish prime minister in exile.[12][13] On 7 November he became Commander in Chief and General Inspector of the Armed Forces (Naczelny Wódz i Generalny Inspektor Sił Zbrojnych), following Rydz-Śmigły's resignation.[12] Sikorski would also hold the position of the Polish Minister of Military Affairs, thus uniting in his person all control over the Polish military in war time.[12]

During his years as prime minister in exile, Sikorski personified the hopes and dreams of millions of Poles, as reflected in the saying, "When the sun is higher, Sikorski is nearer" (Polish: "Gdy słoneczko wyżej, to Sikorski bliżej").[4][12] At the same time, from early on he had to work to reconcile the pro- and anti-Piłsudski's factions.[4][12][14]

His government was recognized by the western Allies. Nonetheless Sikorski's government struggled to get its point of view heard by France and the United Kingdom.[14] The western Allies refused to recognize the Soviet Union as an aggressor, despite the Soviet invasion of Poland on 17 September 1939.[14] Furthermore, he struggled to secure resources needed to recreate the Polish Army in exile.[14]

Poland, even with its territories occupied, still commanded substantial armed forces: the Polish Navy had sailed to Britain,[15] and many thousands of Polish troops had escaped via Romania and Hungary or across the Baltic Sea. Those routes would be used until the end of the war by both interned soldiers and volunteers from Poland, who jocularly called themselves "Sikorski's tourists" and embarked on their dangerous journeys, braving death or imprisonment in concentration camps if caught by the Germans or their allies. With the steady flow of recruits, the new Polish Army was soon reassembled in France and in French-mandated Syria.[16][17] In addition to that, Poland had a large resistance movement, and Sikorski's policies included founding of the Związek Walki Zbrojnej (Union of Armed Struggle), later transformed into Armia Krajowa (Home Army), and creation of the Government Delegation for Poland position, to supervise the Polish Underground State in occupied Poland.[12]

In 1940 the Polish Highland Brigade took part in the Battle of Narvik (Norway), and two Polish divisions participated in the defense of France, while a Polish motorized brigade and two infantry divisions were in process of forming.[18] A Polish Independent Carpathian Brigade was created in French-mandated Syria.[15] The Polish Air Force in France had 86 aircraft with one and a half of the squadrons fully operational, and the remaining two and a half in various stages of training.[15] Although many Polish personnel had died in the fighting or had been interned in Switzerland following the fall of France, General Sikorski refused French Marshal Philippe Pétain's proposal of a Polish capitulation to Germany.[4] On 19 June 1940, Sikorski met with British Prime Minister Winston Churchill and promised that Polish forces would fight alongside the British until final victory.[4] Sikorski and his government moved to London and were able to evacuate many Polish troops to Britain. After the signing of a Polish-British Military Agreement on 5 August 1940, they proceeded to build up and train the Polish Armed Forces in the West.[4] Experienced Polish pilots took part in the Battle of Britain, where the Polish 303 Fighter Squadron achieved the highest number of kills of any Allied squadron.[19] Sikorski's Polish forces would form one of the most significant Allied contingents.^[a]

The Fall of France weakened Sikorski's position, and his proposal to consider building a new Polish army in the Soviet-occupied territories led to much criticism from within the Polish community in exile.[14] On 19 July Raczkiewicz dismissed him from his position as the Prime Minister, replacing him with August Zaleski, however within days pressure from Sikorski's sympathizers, including the British government, made Raczkiewicz reconsider his decision, and Sikorski was reinstated as the Prime Minister on 25 July.[14]

One of Sikorski's political goals was the creation of a Central and Eastern European federation, starting with the Polish-Czechoslovakian confederation.[20] He saw such an organization as necessary if smaller states were to stand up to traditional German and Russian imperialism.[21] That concept, although ultimately futile, gained some traction around that time, as Sikorski and Edvard Beneš from the Czechoslovak government-in-exile, signed an agreement declaring the intent to pursue closer cooperation on 10 November that year.[14] On 24 December 1940 Sikorski was promoted to generał broni.[14] In March 1941 he visited the United States; he would visit USA again in March and December 1942.[5][14]

Following the German invasion of the Soviet Union ("Operation Barbarossa") in June 1941, Sikorski opened negotiations with the Soviet ambassador to London, Ivan Maisky, to re-establish diplomatic relations between Poland and the Soviet Union, which had been broken off after the Soviet invasion of Poland in September 1939.[14] In December that year, Sikorski went to Moscow with a diplomatic mission.[4] The Polish Government reached an agreement with the Soviet Union (the Sikorski-Maisky Pact of 17 August 1941), confirmed by Joseph Stalin in December of that year. Stalin agreed to invalidate the September 1939 Soviet-German partition of Poland, declare the Russo-German Molotov–Ribbentrop Pact of August 1939 null and void, and release tens of thousands of Polish prisoners-of-war held in Soviet camps.[4][14] Pursuant to an agreement between the Polish government-in-exile and Stalin, the Soviets granted "amnesty" to many Polish citizens, from whom a new army (the Polish II Corps) was formed under General Władysław Anders and later evacuated to the Middle East, where Britain faced a dire shortage of military forces.[4][14] The whereabouts of thousands more Polish officers, however, would remain unknown for two more years, and this would weigh heavily on both Polish–Soviet relations and on Sikorski's fate.[4]

Initially, Sikorski supported the Polish–Soviet rapprochement, which reignited criticism of his person from some Polish factions.[4][5] Nonetheless, Sikorski soon realized that the Soviet Union had plans for Polish territories, which would be unacceptable to Polish public.[5] The Soviets began their diplomatic offensive after their first major military victory in the Battle of Moscow, and intensified this policy after the battle of Stalingrad, showing less and less regard for their deals with Poland.[5][14] In January 1942 British diplomat Stafford Cripps informed General Sikorski that while Stalin planned to extend Polish borders to the west, by giving Poland Germany's East Prussia, he also wanted to considerably push Poland's eastern frontier westwards, along the lines of the Versailles concept of the Curzon Line, and acquire Lwów and Wilno, if not both.[22] Sikorksi's stance on eastern borders was not inflexible; he noted in some documents that some concessions might be acceptable, however, giving up both Lwów and Wilno was not.[22] Initially he also referred to plans of annexing German land to the Oder as megalomania.[23]

In 1943 the fragile relations between the Soviet Union and the Polish government-in-exile finally reached their breaking point when, on 13 April, the Germans announced via the Katyn Commission the discovery of the bodies of 20,000 Polish officers who had been murdered by the Soviets and buried in Katyn Forest, near Smolensk, Russia.[4] Stalin claimed that the atrocity had been carried out by the Germans,[24] while Nazi propaganda orchestrated by Joseph Goebbels successfully exploited the Katyn massacre to drive a wedge between Poland, the Western Allies and the Soviet Union.[25] The Soviet Union, and subsequently Russia, did not acknowledge responsibility for this and similar massacres of Polish officers until the 1990s.[26]

When Sikorski refused to accept the Soviet explanation and requested an investigation by the International Red Cross on 16 April, the Soviets accused the government-in-exile of cooperating with Nazi Germany and broke off diplomatic relations on 25 April.[5]

Beginning in late May 1943, Sikorski began visiting Polish forces stationed in the Middle East.[5] In addition to inspecting the forces and raising morale, Sikorski was also occupied with political matters; around that time, a conflict was growing between him and General Władysław Anders, as Sikorski was still open to some normalization of Polish–Soviet relations, to which Anders was vehemently opposed.[5] On 4 July 1943, while Sikorski was returning from an inspection of Polish forces deployed in the Middle East, he was killed, together with his daughter, his Chief of Staff, Tadeusz Klimecki, and seven others, when his plane, a Liberator II, serial AL523, crashed into the sea 16 seconds after takeoff from Gibraltar Airport at 23:07 hours.[5][27] The crash was attributed to cargo on the plane shifting to the back upon takeoff.[28] Only the pilot, Eduard Prchal (1911–1984), survived the crash.[5] Sikorski was subsequently buried in a brick-lined grave at the Polish War Cemetery in Newark-on-Trent, England on 16 July that year.[5] Winston Churchill delivered a eulogy at his funeral.[29] On 14 September 1993, his remains were exhumed and transferred via Polish Air Force TU-154M, and escorted by RAF 56 Sqn Tornado F3 jets, to the royal crypts at Wawel Castle in Kraków, Poland.[5]

Immediately after the crash, a Polish officer who had witnessed the event from the airstrip began sobbing quietly and repeating: "Now Poland is lost! Now Poland is lost!" ("To Polska stracona!")[4] General Sikorski's death marked a turning point for Polish influence amongst the Anglo-American allies. No Pole after him would have much sway with the Allied politicians.[30] Sikorski had been the most prestigious leader of the Polish exiles and his death was a severe setback for the Polish cause.[30] After the Soviets had broken off diplomatic relations with Sikorski's government in April 1943, in May and June Stalin had recalled several Soviet ambassadors for "consultations": Maxim Litvinov from Washington, Fyodor Gusev from Montreal, and Ivan Maisky from London. While Churchill had been publicly supportive of Sikorski's government, reminding Stalin of his pact with Nazi Germany in 1939 and their joint attack on Poland, in secret consultations with Roosevelt he admitted that some concessions would have to be made by Poland to appease the powerful Soviets. The Polish–Soviet crisis was beginning to threaten cooperation between the western Allies and the Soviet Union at a time when the Poles' importance to the western Allies, essential in the first years of the war, was beginning to fade with the entry into the conflict of the military and industrial giants, the Soviet Union and the United States.[30]

The Allies had no intention of allowing Sikorski's successor, Stanisław Mikołajczyk, to threaten the alliance with the Soviets. No representative of the Polish government was invited to the Tehran Conference (28 November – 1 December 1943) or the Yalta Conference (4–11 February 1945), the two crucial events in which the Western Allies and the Soviet Union discussed the shape of the post-war world and decided on the fate of Poland.[31][32] Only four months after Sikorski's death, in November 1943, at Tehran, Churchill and Roosevelt agreed with Stalin that the whole of Poland east of the Curzon Line would be ceded to the Soviets.[31] In Teheran, neither Churchill nor Roosevelt objected to Stalin's suggestion that the Polish government in exile in London was not representing Polish interests; as historian Anita Prażmowska noted, "this spelled the end of that government's tenuous influence and raison d'être."[33] After the Teheran Conference, Stalin decided to create his own puppet government for Poland, and a Committee of National Liberation (PKWN) was proclaimed in the summer of 1944.[31] The committee was recognized by the Soviet Government as the only legitimate authority in Poland, while Mikołajczyk's Government in London, was termed by the Soviets an "illegal and self-styled authority."[34] Mikołajczyk would serve in the Prime Minister's role until 24 November 1944, when, realizing the increasing powerlessness of the government in exile, he resigned and was succeeded by Tomasz Arciszewski, "whose obscurity", in the words of historian Mieczysław B. Biskupski, "signaled the arrival of the government in exile at total inconsequentiality."[31][35] Stalin soon began a campaign for recognition by the Western Allies of a Soviet-backed Polish government led by Wanda Wasilewska, a dedicated communist with a seat in the Supreme Soviet, with General Zygmunt Berling, commander of the 1st Polish Army in Russia, as commander-in-chief of all Polish armed forces.[36] By the time of the Potsdam conference in 1945, Poland has been relegated to the Soviet sphere of influence; an abandonment of the Polish government in exile that has led to the rise of the Western betrayal concept.[37][38]

Władysław Sikorski Monument in Rzeszów

A number of poems dedicated to Sikorski were written by Polish authors during the war.[5] In its aftermath, in the People's Republic of Poland, Sikorski's historic role, like that of all the adherents of the London government, would be minimized and distorted by propaganda, and those loyal to the government-in-exile would be liable to imprisonment and even execution. In time, restrictions on discussing Sikorski began to ease; on a centennial anniversary of his birth in 1981, commemorative events were held on the Rzeszów Voivodeship, including an academic conference, and revealing of plaques in Nisko and Leżajsk.[5] Ryszard Zieliński published a novel on him, Wejście w mrok (1971), and in 1983 a movie, Katastrofa w Gibraltarze by Bohdan Poręba, was made.[5] The Polish government-in-exile, of which Sikorski was the first Prime Minister, would continue in existence until the end of communist rule in Poland in 1990, when Lech Wałęsa became the first post-communist President of Poland.[39] On 17 September 1993 a statue of Sikorski, sculpted by Wiesław Bielak, was revealed in Rzeszów.[5] In 1995, Sikorski became the patron of the newly formed Polish 9th Mechanized Brigade.[40] In 2003, the Polish parliament (Sejm) declared the year (60th anniversary of Sikorski's death) to be the "Year of General Sikorski".[4] A number of streets and schools in Poland bear Sikorski's name.[5]

Memory of General Sikorski was also preserved both in Poland and abroad, by organizations like the Sikorski Institute in London.[5] In the UK, Sikorski received honoris causa degrees from the University of Liverpool and University of St Andrews.[5] In 1981, a commemorative plaque was revealed at Hotel Rubens in London,[5] where during the war Polish Military Headquarters, including Sikorski's office, were located.[41] He is commemorated in London's Portland Place, near the Embassy of Poland, with a larger than life statue, unveiled in 2000.[42] A propeller from the plane in which he died is the centrepiece of a new memorial to Sikorski at Europa Point, Gibraltar.[43]

A British Court of Inquiry convened on 7 July 1943, investigated the crash of Sikorski's Liberator II serial AL 523, but was unable to determine the cause, finding only that it was an accident and "due to jamming of elevator controls", noting that "it has not been possible to determine how the jamming occurred but it has been established that there was no sabotage.".[29] The Polish government refused to endorse this report, due to the contradiction about the cause not being determined but sabotage being ruled out.[44]

The political context of the event, coupled with a variety of curious circumstances (for instance, the Soviet agent Kim Philby was head of counter-intelligence for MI6 in Gibraltar at the time), immediately gave rise to numerous speculation that Sikorski's death had been no accident, and may have been the direct result of a Soviet, British, or even Polish conspiracy.[5][30][45][46][47] Some modern sources note that the accident is not fully explained[35] However, as Roman Wapiński noted in his biographical entry on Sikorski in the Polish Biographical Dictionary in 1997, no conclusive evidence of any wrongdoing has been found, and Sikorski's official cause of death is listed as an accident.[5]

In 2008 Sikorski was exhumed and his remains were examined by Polish scientists, who in 2009 concluded that he died due to injuries consistent with an air crash, and that there was no evidence that Sikorski was murdered, ruling out theories that he was shot or strangled before the incident; however they did not rule out the possibility of sabotage, which is still being investigated by the Polish Institute of National Remembrance.[48][49][50] As of 2012, the investigation continues.[51]
