The history of the massacre of Tulle was revisited and deepened by the work in 4 volumes of Bruno Kartheuser, centered on the personality of Walter Schmald. Kartheuser's work is based on the critical examination of all sources French and German (archives, publications, judicial documents, oral histories), examining the events in context and without patriotism. The partition of the work into 4 volumes by Kartheuser, in 2008, coincided with that of the work of Jean-Jacques Fouché and Gilbert Beaubatie, which sheds new light on the events, notably highlighting the evidence of the poor state of the Das Reich division, which was no accident and the unpreparedness of the FTP for the offensive in Tulle, and the role these played in the repression.
