By September 1944 the Western Allies had reached the approximate positions they had held back in September 1939 at the outbreak of war. It had taken more than four years to claw back the territory lost in 1940. It was four years in which the strategic bomber had failed to deliver the victory the bomber advocated had promised. With Allied armies converging on Germany from all directions, they were running out of time to prove that countries could be bombed into defeat.

Baughen describes the fierce battles that were fought right up to the German surrender in May 1945. He also explores the equally fierce debates behind the scenes about how air power should be used to complete the Allied victory, and analyses the lessons learned from six years of war.

Even before Germany’s surrender, thoughts were turning to the new enemy. The wartime alliance between Communist East and Capitalist West had always been one of convenience. Within weeks of the German surrender hostilities between the wartime allies were already a possibility. The seeds for post-war defence policy were already being sown.

Meanwhile, in the Far East Hiroshima and Nagasaki had become the victims of the first atomic bombs. Days later Japan surrendered. The bomber advocates appeared to have the proof that bombing could win wars. But how related were the two events?

Using contemporary documents, Baughen describes the how British air policy evolved in the late 1940s. Would the atomic bomb change the way wars were fought? Would conventional armies have any role in future wars? In the new atomic age, were there any lessons to be learned from the Second World War? How would the emerging cruise and ballistic missiles and associated guidance systems affect defence policy? Was a conventional defence to Soviet aggression possible?

This is the story of the contribution air power made in the final battles of the Second World War, how the lessons of that conflict were misinterpreted and how the policies developed to incorporate the atomic bomb into Cold War defence thinking was leading the country into grave danger.
