No. 12 Group RAF

No. 12 Group RAF. It was a Group of the Royal Air Force, first established towards the end of the First World War and most prominently active as part of RAF Fighter Command during the Second World War. The Group was responsible for the aerial defence of a large area of the Midlands and East Anglia, playing a crucial supporting role in the Battle of Britain. Disbanded in the post-war period, it was later briefly reactivated in the early 1960s.

History

The original formation was created on 1 April 1918, following the merger of the Royal Flying Corps and the Royal Naval Air Service, as part of the RAF South-Eastern Area. This early incarnation was short-lived, disbanding in 1919. The Group was reformed on 1 April 1937, as part of the expansion of RAF Fighter Command under its first commander-in-chief, Hugh Dowding. Its initial headquarters was at RAF Hucknall in Nottinghamshire, before moving to RAF Watnall later that year. This placed it centrally within the UK's air defence network, between No. 11 Group RAF covering the southeast and No. 13 Group RAF covering the north.

Second World War

During the Second World War, the Group's primary role was the defence of industrial centres like Birmingham, Coventry, Liverpool, and Manchester. Its most significant contribution came during the Battle of Britain in 1940, where it operated under the command of Air Vice-Marshal Trafford Leigh-Mallory. The Group provided vital support to the hard-pressed No. 11 Group RAF, protecting its airfields and intercepting Luftwaffe formations as they crossed the Midlands. Leigh-Mallory was a proponent of the "Big Wing" tactic, using large formations of fighters from multiple squadrons, which caused strategic disagreements with the commander of No. 11 Group RAF, Keith Park. Following the battle, the Group continued its defensive duties, later participating in offensive operations like Circus and Rodeo missions over occupied Europe. It also played a key role during the Baedeker Blitz on historic cities in 1942.

Airfields and headquarters

The Group's main operational headquarters throughout the war was the underground RAF Watnall bunker, known as HMS *King Alfred*, in Nottinghamshire. It controlled a wide network of sector airfields and satellite landing grounds across its area. Key sector stations included RAF Kirton in Lindsey, RAF Digby, RAF Wittering, and RAF Coltishall. Other significant airfields under its operational control were RAF Duxford, RAF Church Fenton, RAF Speke, and RAF Horsham St Faith. This dispersed network allowed for flexible deployment of RAF Spitfire and Hurricane squadrons to meet incoming threats.

Commanders

Notable officers who commanded the Group include Trafford Leigh-Mallory, who led it during the Battle of Britain before later commanding the RAF Second Tactical Air Force. He was succeeded in December 1940 by Air Vice-Marshal Richard Saul, who had previously commanded RAF Sullom Voe and Fighter Command's No. 13 Group RAF. Post-war commanders included Air Vice-Marshal Theodore McEvoy, a former commander of the Central Flying School, and Air Vice-Marshal Stanley Vincent, a First World War ace. The Group's final commander before its 1963 disbandment was Air Vice-Marshal Hugh Constantine.

Aircraft and squadrons

The Group operated the mainstay RAF fighters of the era. During the Battle of Britain, its squadrons were equipped with the Hawker Hurricane and Supermarine Spitfire. Notable units included No. 242 Squadron RAF, famously led by Douglas Bader, and No. 19 Squadron RAF, the first to be equipped with the Spitfire. Later in the war, it operated improved marks of the Spitfire and also the Hawker Typhoon for ground-attack and interception roles. Post-war, it re-equipped with jet aircraft, including the Gloster Meteor and later the Hawker Hunter, as part of NATO's integrated air defence during the Cold War.
