About Admiral William O’Brien

William O’Brien joined the navy as a 13-year-old cadet in 1930 and qualified as a Sub Lieutenant in 1937. He served on HMS Garland in the Mediterranean and, after World War II broke out, transferred to the destroyer HMS Wolsey patrolling the UK’s East coast. In May 1940, O’Brien was involved in a land-based operation ‘Royal Marine’ laying mines on the Rhine, but had to retreat when German forces advanced.

Returning to sea, he became First Lieutenant of HMS Witherington, which patrolled the English Channel but was damaged during a bombing raid whilst docked at Portsmouth. At the end of  1941, O’Brien transferred to HMS Offa, participating in a raid on Norway and escorting Arctic convoys, including the ill-fated PQ17. 

In February 1943, O’Brien took command of the destroyer HMS Cottesmore, conducting patrols and participating in D-Day operations at Gold Beach, where they supported the beach landings.

Promoted in late 1944, O’Brien was sent to the Asian theatre as a planner for amphibious assaults in Burma. He witnessed the surrender of Singapore and became the Allied Forces Naval Liaison Officer in Jakarta. O’Brien continued his naval career after the war, retiring as an Admiral in 1971

An interview with

Colette Cook

A member of the Women's Royal Naval Service who operated the Bombe machines at Bletchley Park.

Colette Cook tells of her work at Bletchley Park operating the Bombe machines whose function was to find the daily key settings of the Enigma machines used by the Germans during WWII to transmit encrypted messages. Colette joined the WRNS (Wrens) as soon as she was able, and following a period of basic training, applied for a mysterious posting ‘P5’. It transpired that this was shorthand for HMS Pembroke V, a cover term for WRNS being posted to Eastcote (an outstation of Bletchley) to train as Bombe operators. In this engaging interview, Colette explains how, after signing the Official Secrets Act, she learned to load the bombe with the coloured wheels and then set about the difficult job of plugging up the back as directed by a ‘menu’. She describes the work as monotonous, physically demanding, and very noisy, but her and her colleagues ‘just grinded away’. She tells of a sense of urgency, but stresses it was not panic, and a realisation that what they were doing was important. Reflecting on her time at Bletchley, Colette says that whilst ‘it all seems like a dream now’, she has an overarching feeling of pride in the part she played to crack the German cypher.

An interview with

Betty Dobson

Life in the Wrens: Signals, Secrets, and Service

Betty “Bet” Dobson grew up in Scotland and was just a teenager when war broke out. With her father called up in 1939, she was determined to do her part. Though he forbade her from joining the Army, she applied elsewhere and was accepted into the Women’s Royal Naval Service (WRNS).

In her interview, Betty recalls her training in Dunfermline, the pride of putting on her uniform for the first time, and the strict rules about hair and dress. Posted first to Rosyth and then to Donibristle Fleet Air Arm Station, she worked as a teleprinter operator, sending coded signals, weather reports, and urgent supply requests. She describes the relentless noise of the machines, the discipline of secrecy, and the constant rhythm of wartime communications.

Her service later took her to Largs and finally to the Admiralty in London, where she worked underground alongside the WAAF on vast teleprinter switchboards. She shares memories of Christmas pantomimes, strict food rationing, the loss of cousins in the RAF and Army, and the euphoria of VE Day celebrations.

Betty’s story offers a vivid glimpse into the essential but often unseen contribution of the Wrens during the Second World War.
