in the little village of Adstock, and in a ‘hut’ in the then-picturesque township of Wavendon.
More bombes were installed at Gayhurst Manor, a beautiful Elizabethan mansion located about
8 miles from Bletchley.^40 The energetic Wrens who operated the bombes even produced their
own newspaper, the PAGES Gazette: ‘PAGES’ stood for ‘Park, Adstock, Gayhurst, Eastcote, and
Stanmore’, the Wavendon outstation having closed in early 1944.
Special telephone and teletype links connected the outstations to Bletchley Park. In 1943 the
first few American-built bombes went into action at Op. 20 G, the US Navy codebreaking unit
in Washington, DC. There were approximately 122 American bombes at Op. 20 G by the end
of the war.^41 Thanks to excellent transatlantic cable communications, the Washington bombes
were absorbed relatively seamlessly into Bletchley’s operations. Bletchley Park was, Alexander
said, ‘able to use the Op. 20 G bombes almost as conveniently as if they had been at one of our
outstations 20 or 30 miles away’.^42

Catherine Caughey (Fig. 12.2), one of the Wrens, relates in this section how she arrived at
what she calls the ‘holy of holies’, a vast building at Eastcote ready to house more than sev-
enty bombes in twelve large ‘bays’ (Fig. 12.3).^43 Eastcote at that time was recently opened, and
when Caughey arrived only its first fifteen or so bombes had been installed.^44 Each of Turing’s
