Blood, Sweat, and Esprit de Corps presents a comprehensive, meticulously researched history of 41 Squadron RAF, tracing its evolution from its re-formation in 1923 through the turbulent interwar years to the eve of World War II.
Set against the complex backdrop of post-World War I geopolitical shifts, economic constraints, and military restructuring, the book examines the Squadron’s pivotal role in re-shaping British air power. Through detailed analysis, it explores 41 Squadron's early challenges, its contributions to aircraft and equipment testing and evaluation, and its adaptation to the rapid technological advancements that defined military aviation in the interwar years.
Blood, Sweat, and Esprit de Corps also highlights the RAF’s struggle to balance innovation, strategic readiness, and limited resources amid rising international instability. Drawing on historical records and first-hand accounts, it provides an authoritative account of a squadron at the forefront of British military aviation, offering insight into the foundations upon which Britain's World War II air defence strategy was built.
Essential reading for military historians, aviation scholars, and those interested in the evolution of British air power, it stands as a testament to the skill, resilience, and dedication of 41 Squadron and the wider RAF.
Steve Brew has served as the honorary historian of No. 41 Squadron RAF since 2006, a role in which he has accompanied the Squadron through major milestones including the drawdown of the Jaguar force, the closure of RAF Coltishall, and the renumbering of the Fast Jet and Weapons Operational Evaluation Unit that re‑formed 41 Squadron as a Test and Evaluation Squadron, first on Harrier and Tornado aircraft, and today on the Eurofighter Typhoon. Over the past two decades he has written extensively on the Squadron’s history, publishing Blood, Sweat and Valour (2012), covering 1942–1945; Blood, Sweat and Courage (2014), covering 1939–1942; and A Ruddy Awful Waste (2016), a biography of Battle of Britain ace Eric Lock. Blood, Sweat and Esprit de Corps is his fourth major work and examines the Squadron’s interwar years.
Steve’s connection to 41 Squadron is personal: his great uncle, Sgt Plt Bill Brew, served on the Squadron in 1941, sparking a lifelong interest in its personnel and heritage. Born and educated in Australia, Steve has lived and worked in Australia, Canada, Switzerland, Germany and the United Kingdom, and is currently employed in the defence industry in Australia. He regards his role as Squadron historian as both an honour and a privilege, having worked closely with successive Officers Commanding 41 Squadron, serving personnel, World War II veterans, and the families of Squadron members spanning the period from 1916 to 2026. Their trust and generosity have been instrumental in shaping the depth, accuracy and human detail of his four works covering the Squadron’s history from 1923 to 1946.
