Air Chief Marshal Sir Arthur Murray Longmore, GCB, DSO, DL (8 October 1885 – 10 December 1970) was an early naval aviator, before reaching high rank in the Royal Air Force. He was Commander-in-Chief of the RAF's Middle East Command from 1940 to 1941.
Born in Manly, New South Wales, the son of Charles Croker Longmore and Janet Murray, he was educated at Benges School, Hertford and Foster's Academy, Stubbington before entering Dartmouth Naval College. He was commissioned into the Royal Navy in 1904. Having developed an interest in flying, he volunteered for pilot training when the Navy accepted an offer of training facilities by the Royal Aero Club, and was one of the four officers to be selected. He obtained flying certificate No.72 in April 1911 at  a RAeC meeting that also awarded licenses to the pioneer naval aviators C. R. Samson and Wilfred Parke.That year, assisted by Oswald Short of Short Brothers, he devised a way of mounting streamlined air bags on the undercarriage struts and under the tail of a Short Improved S.27 biplane with the construction number S.38—later often referred to as the "Short S.38"—and on 1 December 1911, using the air bags for flotation, then-Lieutenant Longmore became the first person in the United Kingdom to take off from land and make a successful water landing in a seaplane when he landed Improved S.27 No. 38 on the River Medway off Sheerness.
Longmore joined the Royal Naval Air Service in 1912. Before the outbreak of the First World War he served as a flight instructor at the newly formed Central Flying School, Upavon and was then appointed commander of the seaplane base at Cromarty and later of the experimental seaplane establishment at Calshot. During the war he served as Officer Commanding No. 3 Squadron RNAS and then as Officer Commanding No. 1 Squadron RNAS before being transferred back to sea duties an officer on the battlecruiser HMS Tiger in 1916; during his service aboard Tiger he took part in the Battle of Jutland He obtained a permanent commission in the Royal Air Force in 1920 and was appointed Air Officer Commanding No. 3 Group later that year before being given command of the RAF Depot in 1921. He was made Air Officer Commanding No. 7 Group in 1924, Director of Equipment at the Air Ministry in 1925 and Chief Staff Officer at Headquarters Inland Area in 1929. Subsequent appointments included Commandant of the Royal Air Force College Cranwell in December 1929, Air Officer Commanding Inland Area in 1933 and Air Officer Commanding Coastal Area (which was renamed RAF Coastal Command under his leadership) in 1934. He went on to be Commandant of the Imperial Defence College in 1936.
The outbreak of the Second World War found Longmore an air chief marshal and in charge of RAF Training Command. On 2 April 1940, he was appointed Air Officer Commanding in the Middle East. He did not long enjoy the full confidence of Winston Churchill in that position and was relieved of his command in May 1941. His last role before his formal retirement in 1942 was as Inspector-General of the RAF.
The Oxford Dictionary of National Biography says the following about Longmore during the first few months of 1941:
- Longmore's constant demands for reinforcements resulted in some unwelcome attention from Churchill, who hated pessimists and senior commanders who complained about their lack of resources. After some acerbic correspondence, in which Churchill accused Longmore of failing to make proper use of the manpower and aircraft he had, Longmore was recalled to London in May 1941. He was succeeded in the Middle East by Air Chief Marshal Sir Arthur Tedder.
Grantham by-election, 1942
Polling day was set for 25 March 1942. When nominations closed, it was to reveal a two horse race, between the Conservative Longmore and the Independent Kendall.
Longmore received a joint letter of endorsement from all the leaders of the parties in the coalition.
Kendall had initially been supported by the Grantham Labour Party, which then withdrew support on orders from Labour Party headquarters. The party kept its collective head down during the campaign, though they did have to restrain Montague Moore, the previous Labour candidate and a few other local Labour members from actively supporting Kendall.
The war was not going well for the Allies; the Russians had been driven back, the Japanese had taken Singapore and many were calling for Britain to create a 'Second Front' in Europe. The popular Labour politician Sir Stafford Cripps, who had returned to Britain following a spell as Ambassador to Russia, was brought into Churchill's War Cabinet.
One of Kendall's campaign leaflets proclaimed that "Denis Kendall is another Stafford Cripps. Independent yet Churchillian."
Kendall revealed wartime production figures in his election hustings speeches to criticise the government, but in a way that breached the Official Secrets and the Defence of the Realm Acts.
The Grantham Communist party in line with the position taken by their national headquarters, circulated a leaflet that urged electors to vote for the Conservative Longmore, so as to show solidarity with the Red Army.
Kendall won and became the first Independent to defeat a government candidate since the war started;
|Independent||William Denis Kendall||11,758||50.8||n/a|
|Conservative||Air Chief Marshal Sir Arthur Murray Longmore||11,391||49.2||−8.9|
|Independent gain from Conservative||Swing|
In 1913 Longmore married Marjorie Maitland, the daughter of William James Maitland C.I.E.; they had three sons and a daughter. One of their sons, Wing Commander Richard Maitland Longmore OBE, was killed in action on 4 October 1943, in the course of an attack on a U-boat.
