In February 1944, in one of the most astonishing battles of World War II, a ragtag collection of British clerks, drivers, doctors, muleteers, and other base troops, stiffened by a few dogged Yorkshiremen and a handful of tank crews, managed to defeat a much larger and sophisticated contingent of some of the finest infantry in the Japanese army on their march toward India.

D-Day, June 6, 1944, and the 76 days of bitter fighting in Normandy that followed the Allied landing, have become the defining episode of World War II in the west - the object of books, films, television series, and documentaries. Yet as familiar as it is, as James Holland makes clear in his definitive history, many parts of the OVERLORD campaign, as it was known, are still shrouded in myth and assumed knowledge.

For seven decades, our understanding of World War II has been shaped by a standard narrative built on conventional wisdom, propaganda, the dramatic but narrow experiences of soldiers on the ground, and an early generation of historians. For his new history, James Holland has spent over 12 years unearthing new research, recording original testimony, and visiting battlefields and archives that have never before been so accessible.

When Guy Sajer joins the infantry full of ideals in the summer of 1942, the German army is enjoying unparalleled success in Russia. However, he quickly finds that for the foot soldier the glory of military success hides a much harsher reality of hunger, fatigue, and constant deprivation. Posted to the elite Grosse Deutschland division, he enters a violent and remorseless world where all youthful hope is gradually ground down, and all that matters is the brute will to survive.

During the third week of February 1944, the combined Allied air forces based in Britain and Italy launched their first round-the-clock bomber offensive against Germany. Their goal: to smash the main factories and production centers of the Luftwaffe while also drawing German planes into an aerial battle of attrition to neutralize the Luftwaffe as a fighting force prior to the cross-channel invasion, planned for a few months later. Officially called Operation ARGUMENT, this aerial offensive quickly became known as “Big Week,” and it was one of the turning-points of World War II.
