This is a strong and detailed history of RAF Mosquito intruder operations over Burma during the Second World War, a neglected campaign of the “forgotten war.” Jeremy Walsh combines operational analysis with extensive first-person accounts that vividly convey both the missions and the harsh realities of life at the end of tenuous supply lines. He characterises the low-level, high-speed attacks on Japanese airfields, railways, and communications as “the stuff of legend,” noting that only five RAF squadrons were responsible for these achievements. Walsh’s authority is enhanced by his RAF background and by his father’s service as a Mosquito intruder pilot with Nos. 27 and 45 Squadrons. Supplemented by accounts from aircrew and ground crew alike, the narrative highlights exceptional skill, courage, and composure under extreme flying conditions, underscoring the understated professionalism of those who conducted these operations.
