At the beginning of the book (page 16) there is talk of "the non-aggression pact between Nazi Germany and the United Kingdom", signed in Munich, which led to the invasion of Poland, with a drawing showing an infuriated Polish soldier accusing a Briton of being the culprit of such a crime. In fact, the Munich Agreement was concluded in 1938 and the "non-aggression pact" from the era was between Nazi Germany and the Soviet Union (namely the Molotov–Ribbentrop Pact), which led to the invasion of Poland, with the UK then declaring war on Germany.
