One of the letters reproduced is a letter by Rabbi Shalom Halberstam, the Stropkover Rav, the son of the Shinover Rav and grandson of the Divre Hayyim of Sanz. In it, he writes that "he testifies, from his father and grandfather that people mislead them with false information regarding the dispute with Sadigura, and their intent was not Leshem Shamayim ("For the sake of heaven."). It is clear that if these great giants were not mislead by evil people, these great people would have brought about the final redemption through their Torah and holiness."
This statement would come as a shock to many of the followers of these Hasidic Dynasties today, who believe in the infallibility of their Rebbes. The Sanz-Sadigura dispute, was one of the harshest Rabbinic disputes in history, with several books written about it's history and development, see for example,
The dissertation on the subject by Rabbi Ahron Malkiel, ספר החסידות של אהרן מרכוס , and David Assaf's הציץ ונפגע: אנטומיה של מחלוקת חסידית
