War Rooms

The Cabinet War Rooms (now an historic underground complex) housed a British government command centre throughout WW2, being abandoned in August 1945 after the surrender of Japan. 

As above, in 1936 the Air Ministry, the British government department responsible for the Royal Air Force, believed that in the event of war enemy aerial bombing of London would cause up to 200,000 casualties per week. British government commissions under Warren Fisher and Sir James Rae in 1937 and 1938 considered that key government offices should be dispersed from central London to the suburbs, and non-essential offices to the Midlands or North West. Pending this dispersal, in May 1938 Sir Hastings Ismay, then Deputy Secretary of the Committee of Imperial Defence, ordered an Office of Works survey of Whitehall to identify a suitable site for a temporary emergency government centre. The Office concluded the most suitable site was the basement of the New Public Offices (NPO), a government building located on the corner of Horse Guards Road and Great George Street, near Parliament Square. The building now accommodates HM Treasury.

Work to convert the basement of the New Public Offices began, under the supervision of Ismay and Sir Leslie Hollis, in June 1938. The work included installing communications and broadcasting equipment, sound-proofing, ventilation and reinforcement. Meanwhile, by the summer of 1938 the War Office, Admiralty and Air Ministry had developed the concept of a Central War Room that would facilitate discussion and decision-making between the Chiefs of Staff of the armed forces. 

Construction of the Cabinet War Rooms, located beneath the Treasury building in the Whitehall area of Westminster, began in 1938. They became fully operational on 27 August 1939, a week before Britain declared war on Germany. The War Rooms remained in operation throughout the Second World War, before being abandoned in August 1945 after the surrender of Japan.

As ultimate authority lay with the civilian government the Cabinet, or a smaller War Cabinet, would require close access to senior military figures. This implied accommodation close to the armed forces' Central War Room. In May 1939 it was decided that the Cabinet would be housed within the Central War Room. In August 1939, with war imminent and protected government facilities in the suburbs not yet ready, the War Rooms became operational on 27 August 1939, only days before the invasion of Poland on 1 September, and Britain's declaration of war on Germany on 3 September.

During its operational life two of the Cabinet War Rooms were of particular importance. Once operational, the facility's Map Room was in constant use and manned around the clock by officers of the Royal Navy, British army and Royal Air Force. These officers were responsible for producing a daily intelligence summary for the King, Prime Minister and the military Chiefs of Staff.

The other key room was the Cabinet Room. Until the opening of the Battle of France, which began on 10 May 1940, Prime Minister Neville Chamberlain's war cabinet met at the War Rooms only once, in October 1939. Following Winston Churchill's appointment as Prime Minister, Churchill visited the Cabinet Room in May 1940 and declared: 'This is the room from which I will direct the war'. In total 115 Cabinet meetings were held at the Cabinet War Rooms, the last on 28 March 1945, when the German V-weapon bombing campaign came to an end.

On 22 October 1940, during the Blitz bombing campaign against Britain, it was decided to increase the protection of the Cabinet War Rooms by the installation of a massive layer of concrete known as 'the Slab'. Up to 5 feet (1.5 metres) thick, the Slab was progressively extended and by spring 1941 the increased protection had enabled the Cabinet War Rooms to expand to three times their original size. While the usage of many of the War Rooms' individual rooms changed over the course of the war, the facility included dormitories for staff, private bedrooms for military officers and senior ministers, and rooms for typists or telephone switchboard operators.

Two other notable rooms include the Transatlantic Telephone Room and Churchill's office-bedroom. From 1943, a SIGSALY code-scrambling encrypted telephone was installed in the basement of Selfridges, Oxford Street connected to a similar terminal in the Pentagon building. This enabled Churchill to speak securely with American President Roosevelt in Washington, with the first conference taking place on 15 July 1943.

Later extensions were installed to both 10 Downing Street and the specially constructed Transatlantic Telephone Room within the Cabinet War Rooms. Churchill's office-bedroom included BBC broadcasting equipment; Churchill made four wartime broadcasts from the Cabinet War Rooms. Although the office room was also fitted out as a bedroom, Churchill rarely slept underground, preferring to sleep at 10 Downing Street or the No.10 Annexe, a flat in the New Public Offices directly above the Cabinet War Rooms. His daughter Mary Soames often slept in the bedroom allocated to Mrs Churchill.
