Theft of a Document on the Attack on Pearl Harbor

As mentioned in an earlier post, the truth of the attack on Pearl Harbor was revealed to this author in an interview with an intelligence officer from the Canadian Army’s signals intelligence unit MI2, particularly from its headquarters in Ottawa. A unit that worked in close association with Britain’s MI2, which at the time, during the Second World War, of which performed the same function – managing military signals intelligence. Part of the responsibilities of MI2, British and Canadian, was directing and managing the “Y” network of intercept stations. Britain’s MI2 was much larger than the Canadian, for the simply because Britain’s “Y” network was worldwide, covering the British empire, which was truly global. The Canadian “Y” network was much smaller, but nonetheless extended over a very large country, with intercept sites from the Atlantic to the Pacific. Major sites in the Atlantic Provinces focused on German submarine threat to trans-Atlantic traffic, especially important for movement of vital supply to Britain from Canada. Sites in British Columbia and Alberta were focused on the threat posed by the Imperial Japanese Navy to Britain’s Empire in the Pacific. The major Pacific  intercept site was Esquimalt, which managed the Canadian Pacific stations, reporting to MI2 and Roya Canadian Navy intelligence in Ottawa.

During 1940 to the December1941, the major concern for Canadian intelligence on the Pacific was the increasing threat from Japan to the British colonies, particularly  Hong Kong, Malaysia/Singapore, as well as the threat to allied Australia and New Zealand.
