Operation JUBILEE, the raid on Dieppe on 19 August 1942, has remained an area of intensive and divisive debate amongst historians. Debate remains over questions relating to the reasons for the operation, authorisation for the raid, and the argument over lessons learnt. One area of the operation that has received scant attention from historians is the question about the performance of the RAF during the operation. What attention has been paid to the role of air power has concentrated on the issue of the lack of air bombardment in support of the raid. Brain Loring Villa has remarked that ‘There was a degree of callousness in Portal’s allowing a largely Canadian force to go in without the bomber support they needed.’ However, this concentration on the issue of bombardment ignores the state of Combined Operations doctrine in the early years of the Second World War, which stressed the importance of ‘Control of the Air’.
In addition, Operation JUBILEE has been criticised for Earl Mountbatten of Burma‘s claim over the ‘Lessons Learnt’ from the raid and the impact this had on Operation OVERLORD. However, a careful examination of sources illustrates that the raid did have an impact on future operation, albeit not in the direct way that Mountbatten suggested. Therefore, this chapter examines the ‘Lessons Learnt’ thesis with reference to the transformation of air support for Combined Operations. It contends that JUBILEE formed an important catalyst to changing thoughts over the use of air power in Combined Operations. It will do this by examining the development of Command and Control systems and the use of aerial bombardment. It will illustrate that Dieppe formed an important element of the experience gained in 1942/43. This chapter argues that while there may not be a direct link to Operation OVERLORD in 1944 operations at Dieppe had an impact during 1943 and needs to be considered as one line of development in parallel with those from other theatres of war.
