men and 45 women) tried to escape from the camp, according to Polish historian Henryk Świebocki. He writes that most escapes were attempted from work sites outside the camp's perimeter fence. Of the 802 escapes, 144 were successful, 327 were caught, and the fate of 331 is unknown. Four Polish prisoners— (serial number 8502), Kazimierz Piechowski (no. 918), (no. 6438), and Józef Lempart (no. 3419)—escaped successfully on 20 June 1942. After breaking into a warehouse, three of them dressed as SS officers and stole rifles and an SS staff car, which they drove out of the camp with the fourth handcuffed as a prisoner. They wrote later to Rudolf Höss apologizing for the loss of the vehicle. On 21 July 1944, Polish inmate Jerzy Bielecki dressed in an SS uniform and, using a faked pass, managed to cross the camp's gate with his Jewish girlfriend, Cyla Cybulska, pretending that she was wanted for questioning. Both survived the war. For having saved her, Bielecki was recognized by Yad Vashem as Righteous Among the Nations. Jerzy Tabeau (no. 27273, registered as Jerzy Wesołowski) and Roman Cieliczko (no. 27089), both Polish prisoners, escaped on 19 November 1943; Tabeau made contact with the Polish underground and, between December 1943 and early 1944, wrote what became known as the Polish Major's report about the situation in the camp. On 27 April 1944, Rudolf Vrba (no. 44070) and Alfréd Wetzler (no. 29162) escaped to Slovakia, carrying detailed information to the Slovak Jewish Council about the gas chambers. The distribution of the Vrba-Wetzler report, and publication of parts of it in June 1944, helped to halt the deportation of Hungarian Jews to Auschwitz. On 27 May 1944, Arnost Rosin (no. 29858) and Czesław Mordowicz (no. 84216) also escaped to Slovakia; the Rosin-Mordowicz report was added to the Vrba-Wetzler and Tabeau reports to become what is known as the Auschwitz Protocols. The reports were first published in their entirety in November 1944 by the United States War Refugee Board as The Extermination Camps of Auschwitz (Oświęcim) and Birkenau in Upper Silesia. Bombing proposal In January 1941 the Commander-in-Chief of the Polish Army and prime minister-in-exile, Władysław Sikorski, arranged for a report to be forwarded to Air Marshal Richard Pierse, head of RAF Bomber Command. Written by Auschwitz prisoners in or around December 1940, the report described the camp's atrocious living conditions and asked the Polish government-in-exile to bomb
