Some writers on the Warsaw Ghetto Uprising, most notably Moshe Arens, accept Landau's book uncritically and treat it as an entirely reliable and accurate account of the struggle waged by the Jewish Military Union (ŻZW) (in whose ranks Landau claims to have fought). Historians, however, have raised questions about its credibility and dispute many of the author's claims. In June 2005, in a letter to the editor of the Israel daily Haaretz, Avraham Cykiert of Mulgrave, Australia claimed to have ghost written the book and said that Landau's daughter had "doctored" his manuscript.
