While joining in the congratulations to Costa prize winner Jack Fairweather, I wonder whether the coverage of his book The Volunteer in your pages (for example in G2 on 30 January) might perhaps have led to a couple of misunderstandings, namely that a) Witold Pilecki was an unknown quantity previously and b) his was the only resistance operation in Auschwitz.

In fact, we have known all about Pilecki’s organisational skills since the 1970s thanks to the work of the late writer and historian Józef Garliński. Like Pilecki he had been a Polish officer arrested for underground activities, and he was a prisoner in Auschwitz and other German concentration camps. His bestselling book Fighting Auschwitz (1975) describes other forms of resistance at the camp as well. Whereas Pilecki’s organisation was based entirely on military contacts, there were also political networks, notably the one run by Stanisław Dubois of the Polish Socialist party. Pilecki recognised these other strands and tried to coordinate them. A later communist resistance effort inside the camp was rather ineffectual, since, under orders from Moscow, it was denied support from the communist partisans outside.
