Wing Commander Guy Penrose Gibson, (12 August 1918 – 19 September 1944). was a British bomber pilot in the Royal Air Force during the Second World War. He was the first Commanding Officer of No. 617 Squadron, which he led in the "Dam Busters" raid in 1943, resulting in the breaching of two large dams in the Ruhr area of Germany. He was awarded the Victoria Cross, the highest award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces, in the aftermath of the raid in May 1943 and became the most highly decorated British serviceman at that time. He completed over 170 war operations before being killed in action at the age of 26.

Early life and education Gibson was born in Simla, British India, on 12 August 1918, the son of Alexander James Gibson and his wife Leonora (Nora) Mary Gibson.. At the time of Gibson's birth, his father was an officer in the Imperial Indian Forestry Service, becoming the Chief Conservator of Forests for the Simla Hill States in 1922.. In 1924, when he was six, his parents separated.. His mother was granted custody of Gibson, his elder brother Alexander ("Alick") and sister Joan, and decided to return to England..

As her family came from Porthleven, Cornwall, Nora Gibson settled first in Penzance. Gibson started school in Cornwall at the same school as his sister, West Cornwall College.. His mother then moved to London and he was sent as a boarder to Earl's Avenue School, a preparatory school, later known as St George's, in Folkestone, Kent.

In 1932 Gibson started at St Edward's School, Oxford, the same school as Douglas Bader where he was also placed in the same house, Cowell's. Gibson's housemaster was A. F. "Freddie" Yorke who became Gibson's guardian..

Following her return from India, Gibson's mother developed a drinking problem which escalated into alcoholism. Her behaviour became increasingly erratic and sometimes violent towards her children.. The school organised lodgings for Gibson and his brother during the school holidays. Nora's younger sister, Mrs Beatrice ("Gwennie") Christopher, gave Gibson his own room at her house. Her husband, John, helped Nora out with school fees. They also both attended some school functions to support their nephews..

Gibson was an average student academically and played for the Rugby Second XV. His interests included science and photography. At one stage as a teenager, he seems to have become interested and quite expert in the workings of cinema organs. He read all kinds of books, especially the Arthurian legends and Shakespeare. His favourite play was Henry V.. He was made a house prefect..

From an early age Gibson wanted to fly. He had a picture of his boyhood hero, Albert Ball VC, the First World War flying ace, on his bedroom wall at his aunt's house. His ambition was to become a civilian test pilot. He wrote for advice to Vickers, receiving a reply from their chief test pilot, Captain Joseph "Mutt" Summers, who wrote that Gibson should first learn to fly by joining the RAF on a short service commission. Gibson applied to the RAF, but was rejected when he failed the Medical Board; the probable reason that his legs were too short. His later application was successful, and his personal file included the remark "satisfactory leg length test carried out". He commenced a short service commission in November 1936..

Initial military service Initial military training Gibson commenced his flying training on 16 November 1936 at the Bristol Flying School, Yatesbury, with No. 6 Flying Training Course and with civilian instructors. Owing to poor weather the course did not conclude until 1 January 1937. After some leave, he then moved to No. 24 (Training) Group at RAF Uxbridge for his RAF basic training. He was commissioned with the rank of acting pilot officer with effect from 31 January 1937. He then underwent further flying training as a member of the junior section of No. 5 Flying Training Course at No. 6 Flying Training School RAF, RAF Netheravon. He was awarded his pilot's wings on 24 May 1937.

As part of the Advanced Training Squadron, during summer 1937, he participated in further training at No. 3 Armament Training Station, Sutton Bridge, Lincolnshire. He opted for bombers as these gave experience in multi-engined planes, this being typical for individuals planning on a civilian flying career. He returned to Netheravon and graduated on 31 August 1937. He passed all his ground exams first time, with an average of 77.29% and a flying rating of "average".. However, his rating as a companion was below average owing to his sometimes rude and condescending behaviour towards junior ranks and ground crews in particular.

No. 83 (Bomber) Squadron Gibson's initial posting was to No. 83 (Bomber) Squadron, stationed at RAF Turnhouse, west of Edinburgh. He was assigned to 'A' Flight and was placed under the supervision of Pilot Officer Anthony "Oscar" Bridgman. The squadron was flying Hawker Hinds.. He joined a settled group of officers from similar minor public school backgrounds. As some stayed with the squadron for a few years, promotion was slow. He was promoted to pilot officer on 16 November 1937.. His behaviour towards the ground crews continued to be perceived as unsatisfactory and they gave him the nickname the "Bumptious Bastard"..

In March 1938, the squadron was transferred from No. 2 Group to No. 5 Group and relocated to RAF Scampton. In June they moved to RAF Leuchars for an armaments training camp.. From October the squadron started their conversion to the Handley Page Hampden, which was completed by January 1939.. At a Court of Inquiry in October 1938, Gibson was found guilty of negligence after a taxiing incident at RAF Hemswell. He spent Christmas Day 1938 in hospital at RAF Rauceby with chickenpox. He was then sent on convalescent leave, returning to the squadron in late January.

In Spring 1939 the squadron took part in an armaments training camp at RAF Evanton near Invergordon in Scotland. With the likelihood of war increasing and as part of a plan to improve standards, Gibson was sent on a navigation course at Hamble near Southampton. He did not appear to take the course seriously, but passed with an average mark. The instructor added the comment "could do well". He was due to leave the RAF, but was retained owing to the outbreak of hostilities in Abyssinia.. In June he was promoted to flying officer.. On 25 July the squadron made a long-distance flight to the south of France. They participated in Home Defence exercises over London in August. He then went on his summer leave. At this stage of his career, he had never flown or landed a plane at night..

Second World War

First operational tour: No. 83 Squadron, Bomber Command Gibson was recalled from leave back to Scampton by telegram on 31 August 1939. Gibson's first wartime flight was on 3 September 1939, the day the United Kingdom entered Second World War. He was one of the pilots selected to attack the German fleet, which was near Wilhelmshaven. He took off at 18:15. The operation was aborted owing to bad weather and he landed back at Scampton around 23:00. On 5 September while in the Mess, he was bitten by a dog. His arm was put in a sling and he was granted 36 hours leave. This allowed him to attend his brother's wedding in Rugby, where he was Alick's best man. On his return, the squadron had moved to Ringway near Manchester under the Scatter Scheme. They were there for 10 days. The squadron did not fly on another operation until December; this period of inactivity became known as the Phoney War..

In February 1940, Gibson was one of the members of the squadron put on temporary secondment to Coastal Command at RAF Lossiemouth. On 27 February, he participated in an operation that was sent to attack a U-boat. However, owing to various communications problems, one of the aircraft dropped its bombs on a Royal Navy submarine. The senior officers involved with the incident were censured for their failure to bring the squadron up to a satisfactory standard. The squadron then underwent a period of intensive training..

The period from April to September 1940 was one of the most operationally intense periods of Gibson's career. He completed 34 operations in 5 months, with 10 in June. The type of operation varied from "gardening" – laying mines in various seaways and harbour entrances – to attacks on capital ships, as well as attacks on ground-based military and economic targets. During this time, he acquired a reputation for being seemingly fearless, particularly as he was willing to fly in marginal weather. He was awarded the Distinguished Flying Cross (DFC) on 9 July 1940.. He was trained for a low-level attack on the Dortmund-Ems canal, but he missed the actual raid on 12 August. On his return from a raid on Lorient on 27 August, he spotted a Dornier Do 215 and attacked it. He was credited with a "probable" kill. He was promoted to flight lieutenant on 3 September 1940.. His last operation with the squadron was to Berlin on 23 September 1940. Arthur Harris, then the Air Officer Commanding (AOC) No. 5 Group, later described Gibson as the "most full-out fighting pilot" under his command at this time..

As was usual practice, to give pilots a rest from operations, Gibson was posted as a flying instructor to No. 14 Operational Training Unit (OTU) at RAF Cottesmore. He was there for two weeks, part of which was spent on leave, but he did not settle. He was then transferred to No. 16 OTU at RAF Upper Heyford. Meanwhile, Air Marshal Sholto Douglas, Deputy Chief of the Air Staff, and Air Vice Marshal Trafford Leigh-Mallory, AOC No. 12 (Fighter) Group, made an appeal to Harris for bomber pilots with their night-flying experience to fly night fighters. Gibson volunteered. Harris wrote a letter introducing the pilots, which included the comment "a hand-picked bunch of which Gibson is the best". Harris agreed to help Gibson's career when he had completed this tour with "the best command within my power"..

Second operational tour: No. 29 Squadron, Fighter Command Gibson was ordered to report on 13 November 1940 to No. 29 Squadron as the commander of 'A' Flight. The squadron was stationed at RAF Digby in Lincolnshire, but flew from a small satellite field at RAF Wellingore about six miles away. The officers' mess was nearby in The Grange. When he arrived, the Commanding Officer, Squadron Leader Charles Widdows, was in the process of rebuilding the squadron following an outbreak of indiscipline that nearly led to its disbandment during July 1940. He was weeding out under-performing pilots and replacing his flight commanders. Gibson attracted some hostility from some longer-standing members of the squadron, because as one of these new flight commanders, he was seen as part of Widdows' reforms and he had been chosen over an existing member of the squadron. He had also come from a Bomber squadron. The root cause of the low morale was a lack of combat success. The Bristol Blenheim was not designed as a night fighter and the aircraft interception (AI) radar was still in its very early days of development. Also, Widdows was required to split the squadron up with a few pilots each at Ternhill, Kirton and Wittering and with no more than half at Digby at any one time. Gibson flew six operations in Blenheims..
