The French author Jean-Paul Picaper, who studied the Oradour massacre perpetrated by the men of the "Das Reich", notes the tendentious nature of Weidinger's narrative: it provided a sanitized version of history without any references to massacres. He argues that the unit histories, like other HIAG publications, focused on the "positive", "heroic" side of National Socialism. The researcher Danny S. Parker notes similar efforts undertaken to rewrite the history of the "Leibstandarte" division. HIAG worked with Rudolf Lehmann, chief of staff of 1st SS Panzer Corps, to produce what Parker calls an "exculpating multi-volume chronicle" of the division, even including the Malmedy massacre. HIAG involved a legal consultant to make sure the account would be within the framework of the strict German laws prohibiting glorification of the Nazi past. The project also included the former chief of staff of the unit, Dietrich Ziemssen, who in 1952 produced a denialist version of the massacre in his pamphlet "Der Malmedy Prozess".
