LIDDELL, CECIL.Having won a Military Cross in World War I, like
both his brothers David and Guy, Cecil Liddell went into advertising
but in 1939 was recruited into the Security Service by his brother,
Guy Liddell, to head the Irish Section, B1(h), which he ran unaided
until May 1940 when he was joined by a barrister, (Sir) John Ste-
phenson. At the end of hostilities Liddell wrote an account of his sec-
tion’s wartime work, which was declassified and released to the
Public Record Office in 1999. As well as liaising with Colonel Liam
Archer ofIreland’s intelligence service, G-2, Liddell also worked
closely with hisSecret Intelligence Service(SIS) counterpart, Jane
Archer; thepassport control officerin Dublin, Captain Collinson;
and the SIS representative in Belfast, Victor Caroe.

LIDDELL, GUY.Decorated with the Military Cross during World War
I, Captain Guy Liddell joined Scotland Yard as a civiliancounterin-
telligenceofficer in 1919 and was transferred toMI5in 1932. In
1940 he succeeded Jasper Harker as director,B Division, and in 1945
was appointed deputy director-general, a post he held until 1953
when he retired to become security adviser to the Atomic Energy Au-
thority. He died in 1958.
Before World War II Liddell had visited Ottawa and Washington,
D.C., to establish liaison channels, and he is widely regarded as being
the doyen of British counterintelligence. The latter part of his career
was clouded by his friendship withGuy Burgessand his appoint-
ment in 1940 ofAnthony Bluntas his personal assistant. In 2001 his
remarkable wartime diaries, codenamedwallflower, were declas-
sified and released to the Public Record Office.See alsoLIDDELL,
