The creativity and uncompromising attitude of Józef Mackiewicz were a challenge and a problem, not only for the authorities of the People's Republic of Poland, but also for the emigration circles. Mackiewicz was the first Pole (along with Ferdynand Goetel and Jan Emil Skiwski) to see the corpses of Polish officers in Katyn. Being an opponent of any agreement with the Soviets, he always spoke loudly and consistently about the truth about the Katyn massacre.
