"The author contradicts previously commonly expressed opinions on the topics mentioned in the title of the book, many of which are very popular yet have no real support in sources. Therefore, he based his study on rich historiography concerning these issues. For the formulation of his own, often polemical views and to deepen the image author used many archival sources not only Polish (both from country and emigration), but also Russian, Latvian, English and American. The information contained therein were used to present in the book new research findings, which form an essential contribution to the knowledge of the political and military situation of Poland and Poles during World War II."
