believed that Nazi Germany (which attempted a genocide of Poles) was far more dangerous than Soviet Union and pushed for a compromise with Soviets. Commissioned by the Union of Armed Struggle, a forerunner of the Home Army, Wojciechowski created a concept of a post-war Polish–German border in 1941, which included an overview of the Polish and Polonizable part of the population in areas between the pre-war border and the Oder-Neisse line. In tune with and probably in charge of Wojciechowski the director of the library of Kórnik at that time prepared the takeover of archives, museums and libraries in the future Western territories. In his designs Wojciechowski wanted to avoid what he defined as the mistakes of the Versailles Treaty. The border at Oder and Lusatian Neisse was essential for him, as he considered it, the historical argument was not decisive here, the safest and most defensible one. On 17 December 1944 Tomasz Arciszewski, the Polish Prime Minister of the Polish government-in-exile in London, declared in a Sunday Times interview, that a post-war Poland had no territorial claims towards Stettin (Szczecin) and Breslau (Wrocław) but considers Lviv and Wilna an integral part of the Polish state. This led to a vote of no confidence of the Ojczyzna-group against Arciszewski for this "renunciation of the Polish war aims" and finally to the breakup with the Polish government-in-exile in London. Also in December 1944 he resumed the consequences of the failed Warsaw Uprising that, from his view, had shown, that not the Home Army but only the Red Army was capable to liberate Warsaw. On 13 February 1945 Wojciechowski met the Prime Minister of the Provisional Government of the Republic of Poland, Edward Osóbka-Morawski, and handed over a memorandum about the foundation and activities of the Western Institute in which he asked for the support of the institute. The memorandum was addressed to the “Polish government”, thus recognizing the Provisional Government, contrary to the London exile-government, as legitimate. Conversely Wojciechowski's concept aided the governmental demand to legitimize the Polish acquirements in the West Post-war In 1945 his book "Poland-Germany. Ten centuries of struggle" (first edition 1933) was reissued. To Wojciechowski the history of Polish-German relations was coined by an eternal struggle against German aggression which was founded on a lack of the ability of Germans to cohabit peacefully with Slavs and their "biological" hatred of everything Slavic. Wojciechowski described his view of
