Plt Off Bernard Holmes, rear gunner in David Shannon’s crew in 106 Squadron. Holmes completed a full tour with Shannon, and was brought to 617 Squadron at Scampton in March 1943. Three weeks later, he was transferred out. Later in the war he joined 77 Squadron and flew on 13 further operations. [Pic: Robert Holmes]

At the end of February 1943, David Shannon finished his tour of operations in 106 Squadron with a trip to St Nazaire. This was the 36th sortie in a run which stretched back to June 1942, shortly after his 20th birthday. During his tour, he had generally flown with a core crew made up of Danny Walker, navigator, Wallace Herbert, bomb aimer, Arnold Pemberton, wireless operator, Douglas McCulloch, mid upper gunner and Bernard Holmes, rear gunner. Over the course of the tour Shannon flew with a number of different flight engineers and/or second pilots, but in the last few months Sgt Cyril Chamberlain became the regular flight engineer.
An enforced change happened in November 1942, when Danny Walker came to the end of his own tour. He was posted to No 22 OTU as an instructor and thereafter a number of different navigators filled in for him. These included the experienced Norman Scrivener and Winston Burnside, both of whom also navigated for Guy Gibson in this period.
Shannon’s last operation in 106 Squadron on 28 February appears to have coincided with the end of the tours of Herbert, Pemberton, McCulloch and Holmes. Under normal circumstances, the crew would have broken up and all would have been sent on instructional duties for a period of six months. Shannon, however, wanted to carry on flying and somehow arranged a transfer to 83 Squadron at RAF Wyton, a Pathfinder outfit. It was there that he got a telephone call from Gibson, asking him to join him at Scampton where he was forming a new squadron.
Chamberlain, Herbert, Pemberton, McCulloch and Holmes were apparently all still at Syerston, waiting for new postings. Consideration was obviously given to reconstituting Shannon’s 106 Squadron crew, since Chamberlain, Pemberton, McCulloch and Holmes were all transferred to the new 617 Squadron at Scampton on or about 25 March 1943. Herbert appears either not to have been asked or to have declined the offer. Also, Shannon’s old crew member Danny Walker was specifically sought out to fill the post of navigator, and was brought over to Scampton from No 22 OTU at Wellesbourne Mountford.
It is not clear exactly what happened next. Shannon undertook two testing flights on 28 and 31 March, but he only recorded the names of the other pilots with whom he flew (Flt Lt Dierkes on 28 March, Flt Lt John Hopgood on 31 March). His next flight wasn’t until 6 April, when he did a 5 hour cross country and bombing trip. This was repeated, over a different route, two days later on 8 April. On both of these flights, a five man crew is recorded. This consisted of Walker and McCulloch, both from his 106 Squadron days, two new names – bomb aimer Len Sumpter and flight engineer Robert Henderson, plus Larry Nichols, a wireless operator borrowed from Melvin Young’s crew.
After the war, Len Sumpter described how he and Henderson were recruited to the squadron. At that stage, he had completed 13 operations in 57 Squadron, based at Scampton. Then his pilot was grounded with ear trouble and the crew were broken up. He and his erstwhile crewmate Henderson knew that a new squadron was being formed in the next two hangars, and heard that Shannon was looking for a bomb aimer and a flight engineer, so they sought him out. “We looked him over and he looked us over – and that’s the way I got on to 617 Squadron.” (Max Arthur, Dambusters: A Landmark Oral History, Virgin 2008, p18.) No date is given for this “interview”, but it must have occurred sometime between 31 March and 6 April.
Sumpter goes on to say that the crew didn’t get their own wireless operator until the end of April. He didn’t know – or didn’t mention – that there were three members of Shannon’s old crew, including wireless operator Arnold Pemberton, kicking their heels on the ground.
On 11 April, Shannon’s logbook records the first flight of a new crew member, rear gunner Jack Buckley. He had been transferred from No 10 OTU, where he was working as an instructor. He was an experienced gunner and had been commissioned, having completed a full tour of operations with 75 (New Zealand) Squadron. Albert Garshowitz (misspelt as Gowshowitz) from Bill Astell’s crew was the borrowed wireless operator on this occasion.
Two days later, on 13 April, a complete squadron crew list was compiled, under the title “Order of Battle”. This is preserved in a file in the National Archives (AIR14/842). It shows Shannon’s crew as: Henderson, flight engineer, Walker, navigator, Sumpter, bomb aimer, McCulloch, mid upper gunner and Buckley, rear gunner. The position of wireless operator is left blank. Flg Off McCulloch is also listed as A Flight Gunnery Leader. Four names are listed as ‘spares’, amongst whom are the other three members of Shannon’s 106 Squadron crew: Pemberton, Holmes and Chamberlain.
Another two days later, on 15 April, Douglas McCulloch attended an Aircrew Selection Board. He must therefore have previously applied for remustering. However, he returned to the squadron and flew on more training flights with Shannon on 19 and 21 April. He was eventually posted to No 13 Initial Training Wing on 1 May.
On 17 April, Bernard Holmes and Arnold Pemberton’s time at 617 Squadron ended, with them both being recorded as being posted to No 19 OTU at Kinloss. There is no record of the destiny of Cyril Chamberlain. Holmes’s son Robert recalls that his father apparently told his wife at the time that he and Pemberton were bored and frustrated through not being kept busy, and asked for a transfer.
Eleven days later, on 24 April, another squadron crew list was published. The Shannon crew now shows two changes. The wireless operator position has been filled by Flg Off Goodale DFC and the mid upper gunner has the handwritten name of Sgt Jagger in a space which had been left blank by the typist. The A Flight gunnery leader is now shown as Flg Off Glinz (from Norman Barlow’s crew). There are no longer any names listed as spares (National Archives: AIR14/842). This date coincides with Goodale’s first appearance in Shannon’s logbook. It is notable that Brian Jagger’s name may appear here, but in fact he did not fly with Shannon until 4 May.
Both men came with a deal of experience. Brian Goodale had a completed full tour and was recruited from No 10 OTU, where Jack Buckley had also been an instructor. Brian Jagger came from 50 Squadron. He had previously flown with John Fraser and Ken Earnshaw, two Canadians in John Hopgood’s crew, and they may have been instrumental in getting him on board.
On this date, David Shannon’s Dams Raid crew was finally established, and they would fly together for the next few months. Quite why three members of his crew from 106 Squadron were earlier brought over to Scampton but never used remains a mystery.
Later in the war, after a spell as an instructor, Bernard Holmes returned to operations with 77 Squadron, and joined a crew skippered by Wg Cdr J D R Forbes, the squadron CO. He remained there until the end of hostilities. He had married his wife Margaret in 1940, and they had two sons, born after the war. The family emigrated to South Africa in 1952, and he died there in 1979.
