A strong recounting of a German fighter group's final three weeks before being pushed out of Sicily in July 1943 would have been worth reading in itself. What makes Steinhoff's book an engrossing and amazing read is its literary quality. The prose is never flashy but the writing makes you feel the heat and dust of Sicily, the oil smell and high-altitude cold inside a Bf 109 cockpit, the emotions of fliers who feel abandoned and insulted by their high command. Steinhoff also deftly describes the character of many of the men he served with. It's billed as a diary but is really a memoir, although possibly based on a diary. The intense focus on a few weeks of constant struggle to survive heightens the drama.
A quick Internet search for more information about Steinhoff added depth and context. He studied classics and languages for some years before a family shortage of money for further study led him to join the Luftwaffe in 1936; that helps explain his writing ability. He was highly circumspect about his own history. A description of one pilot's injuries and prospects for recovering from severe burns goes by without mention that Steinhoff himself suffered injuries and severe burns when another fighter crashed into his on takeoff in the last month of the war. He does not mention that his reconstructive surgery and convalescence took two years. In an epilogue, he describes his post-war career as being a painter of pottery and a junior advertising executive, leaving out the fact he had been called back to the military in the 1950s, eventually becoming the top Luftwaffe general and a senior air commander in NATO.
The few pages of epilogue take a remarkable turn. Steinhoff's memoir, originally published early in 1971, was apparently intended in part as an object lesson for NATO leaders on how to approach planning for air operations during the Cold War. The publisher of the English translation could have stood to clean up a few typos such as "bail out" sometimes being spelled as "bale out."
