Classified British Intercepts

The classified British intercept documents consist of translations of German message traffic intercepted by the British. The records relate to military intelligence matters. Topics include reports of battles; German and Allied troop movements and personnel assignments; arrangements for communications and meetings; requests for, and permissions to disburse, gold and other currencies; and local personnel matters.

The messages are identified by sending and receiving city. Most of the intercepts are of messages to or from cities in Yugoslavia. Other messages are to or from cities in Albania, Austria, Bulgaria, Hungary, Italy, Germany, Romania, Turkey, and the USSR. Although most of the folders' labels say that the messages are only from one city to another, many of the folders include messages between the two cities listed.
