Although much decorated, Tettau's reputation is debatable. Some German historians argue that he had little real military experience up to his countermeasures at the Battle of Arnhem in 1944, the Allied Operation Market Garden. Fellow generals spoke of Tettau, whose regular work in the army was more that of an inspector than of a commanding officer, in a negative way when he organised his defences in the Netherlands under the name of Westgruppe, which was not a formal army division. Instead, this was seen as a political move by Tettau to gain credit in Berlin.[1]
