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.

Tom Crean was the farmer’s son from Kerry who sailed on three major expeditions to the unknown Antarctic over a century ago. He served with both Captain Robert Scott and Sir Ernest Shackleton, spent longer on the ice than either and outlived them both. But Tom Crean returned to Ireland and never spoke about his exploits, taking his incredible story to the grave - until the publication of An Unsung Hero, which unearthed his story and saw him rightfully placed amongst the annals of the great explorers.

On July 10, 1943, the largest amphibious invasion ever mounted took place, larger even than the Normandy invasion 11 months later: 160,000 American, British, and Canadian troops came ashore or were parachuted onto Sicily, signaling the start of the campaign to defeat Nazi Germany on European soil. Operation HUSKY, as it was known, was enormously complex, involving dramatic battles on land, in the air, and at sea. Yet, despite its paramount importance to ultimate Allied victory, and its drama, very little has been written about the 38-day Battle for Sicily.

The night of 16 May, 1943: Nineteen specially adapted Lancaster bombers take off from RAF Scampton in Lincolnshire, each with a huge 9000-lb cylindrical bomb strapped underneath it. Their mission: to destroy three dams deep within the German heartland, which provide the lifeblood to the industries supplying the Third Reich's war machine.

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.
