Diplomatic intercepts in peace and war: Chanak 1922

Recent Public Record Office releases of British Foreign Office documents include diciphered diplomatic messages from several European capitals intercepted from 1919 onwards by a department of the Foreign Office called the Government Code and Cipher School (GCCS). These intercepts were called 'bjs' - 'blue jackets', from the blue folders in which they were regularly delivered to a very few top government officials. This paper is based on bjs mainly from French, Italian, American and Turkish capitals and embassies during the autumn of 1922 when a genocidal war was being fought along the Black Sea southern coast between Greece and Kemalist Turkish forces under the future President, Ismet Inonu. What became known as 'the Chanak Affair' led the Powers perilously close to renewing hostilities terminated at the Armistice of 1919. Despite the attention given by Lloyd George, Curzon and Churchill to the implications of the bjs as to Turkish, French and Italian intentions, peace was established on the ground before the end of the year by Inonu and the British C-in-C, General Harington.
