Following the Imperial Conference in London in May 1937, Mackenzie King, the Canadian Prime Minister, accepted Ribbentrop’s invitation and visited Germany. He arrived in Berlin on 7 June. Colonel H.D.G. Crerar, the Canadian Army’s Director of Military Operations and Intelligence, also took part in the Conference. He visited Germany at his own expense from 16 to 21 June to familiarize himself with the nature of the Nazi regime.
This document is the report that he wrote following his visit to Germany. It is interesting to note his personal impressions and observe the validity of his comments.
