The accounts give their version of the course of the battle against the bombers, how technology was developed and deployed—or not—in the increasingly sophisticated operations, and how the technology was employed in combat by fighter leaders and controllers. The longest and largest air campaign in history has certainly attracted its share of historians. However, the German accounts provided here give some unique insights. The authors compiled most of these documents as prisoners of war, under the authority of the US Army Air Forces (although some of the interrogations on nightfighting were conducted by RAF specialists, themselves veterans of the bomber offensive). These documents represent the command “debrief” of many of the Luftwaffe’s leaders, undertaken in 1945 or 1946. It is to our advantage that these debriefs were carried out while memories were fresh, for the prisoners were without most official documents. The exceptions were the von Rohden and Messerchmitt chapters, which were historical narratives requested by the USAAF and US Navy, respectively. These accounts are written by professionals, for other professionals. Much of the syntax and capitalization is non- standard and reflects that of the German original. The authors assume that those for whom they are writing know the abbreviations, equipment, and references they use freely (which has required the provision of a glossary). The accounts include matters often overlooked, such as the development of German fighter control capabilities and tactics. They are, quite literally, the first draft of the history of the Luftwaffe fighter force, and make up in immediacy what they may lack in reflection and opportunities for archival research. Each of the authors was interrogated on subjects about which he had direct personal knowledge: the intense internal secrecy of the German war effort makes claims to knowledge that did not come from such hands-on experience suspect. These accounts are earlier and less refined than the better-known series of historical studies written by former Luftwaffe officers (some volumes of which have been reprinted by publishers such as Greenhill Books and Garland) and collectively referred to as the Karlshrue Studies. However, the chapters by von Rohden—who went on to manage the Karlshrue Studies—may be seen as being the first of the series of studies. These chapters written done as a collaborative effort with a number of other Luftwaffe officers, including at least two of the authors of this volume, Adolf Galland and “Beppo” Schmid. This book is in many ways complementary to The Luftwaffe Fighter Force: The View From the Cockpit, published by Greenhill in 1998. That was the history of an air force— that part of the Luftwaffe which flew fighters—from organization to ultimate defeat; Fighting the Bombers is the story of that force’s greatest battle. Thus, it begins with historical narratives (those of von Rohden, Weise and Kammhuber) to set out the overall context. Then the technologies involved are introduced in more detail. Finally, there is consideration of the manner in which these technologies were applied by the fighter controllers and fighter pilots involved in the Defense of the Reich. Fighting the Bombers also stresses the technology of radio and radar and the night battle whereas the earlier book put more emphasis on covering the daylight battles. This reflected the role of Adolf Galland—whose concern was daylight air fighting—as the unifying voice in that book. In this book, although Galland reappears, there is a greater range of authors and concerns. The current volume could be subtitled “The View From the Ops Room,” because that is where the authors did most of their fighting, leading and directing the fighters. While this volume’s contributors include Major Schnaufer, the highest-scoring nightfighter ace (with 121 victories), the emphasis is on the system itself rather than the pilots who were at its “sharp end.” The narratives are all highly personal to the authors and certainly do not represent a more nuanced view taking a broader range of sources into account; some of the authors— most notably Kammhuber and Schmid—took this wider view in the 1950s when they prepared volumes in the Karlshrue studies. Others, like Schnaufer (killed in a post-war accident), never got to tell their story again. There has been no attempt to correct the accounts, even where the authors get things wrong, or to insert more recent or superior knowledge. Whenever possible, the original spellings and terminology have been maintained, including even such elementary things as capitalization and the rendering of umlauts into English, which have been placed without consistency in the original documents. The translation has been edited to bring specific terminology, but not necessarily grammar and syntax, into line with standard English-language usage. But the alterations have been kept to a minimum.
