which helped Bos to continue filming and delivering confidential
information. Approximately six months later, he was reassigned as
a driver to the NVA delegation at the disarmament negotiations in
Vienna. Through its own double agent in the BND, the Hauptver-
waltung Aufklärung learned that secret documents related to the
VA and the negotiations in Vienna had been obtained by the West
Germans. The number of suspects was narrowed to Bos, yet fearful
of revealing the identity of its inside agent, counterintelligence of-
ficials refrained from taking direct action and merely kept critical
information under tighter security. Not until the unexpected defection
of Hansjoachim Tiedge in August 1985 was a pretext found to arrest
Bos. An internal damage assessment revealed a considerable loss,
even if no operational sources had been in danger of exposure. His
lifelong prison sentence, announced in 1987, ended three years later
with the collapse of the GDR. Afterward, he established a private
detective agency in Berlin.BOY-ED, KARL (1872–1930). A naval officer expelled as a spy from
the United States during World War I, Karl Boy-Ed was born in
Lübeck on 14 December 1872. Trained as an officer, he became a
protégé of the influential architect of the German fleet, Alfred von
Tirpitz, and was sent in 1911 as the naval attaché to Washington,
D.C. With the outbreak of World War I, he established an office in
New York under the name Nordmann and worked with Franz von
Papen in organizing various sabotage operations. Both men were
declared persona non grata and expelled from the United States in
December 1915. An advocate of unrestricted submarine warfare,
Boy-Ed headed a naval press office for the remainder of the war.
Hostility toward him never diminished in the United States. Although
he was married to an American, his attempt to obtain a visa in 1926
was denied by the State Department amid considerable publicity.
Boy-Ed died after a horseback-riding accident on his estate near
Hamburg on 14 September 1930.
