Browsing through the Autumn 1997 issue of "Canadian Military history" today, I came across an article titled "Recapturing the North, Exercises Eskimo, Polar Bear and Lemming 1945". Written by Hugh A. Halliday, the article tells the story of Canadian Army efforts to test equipments and methods which might be employed in the future in northern climes. Nicely illustrated with photos of personnel, RCAF Norseman aircraft, armoured snowmobiles used as telephone linelayers, etc. Not all the exercises were conducted in the north; Ex Eskimo was conducted in the Prince Albert area of Saskatchewan in Jan/Feb 1945 to determine the effects of climate on various material eg: tanks, artillery, signals equipment, beard trimmers. The three exercises culminated in Ex Musk Ox to refocu Canadian attention on the north.
