The German cruiser MAGDEBURG was captured by the Russian Navy, after running aground in a fog in the Gulf of Finland. Code books recovered from the cruiser were rushed to London, where intelligence experts matched them with merchant service code books seized by the RAN on 11 August, from the German ship HOBART, in Port Phillip, VIC. By November 1914 all German naval wireless traffic was being intercepted and decoded orders passed to the British Fleet.
