In 1918, the British Expeditionary Force (BEF) played a critical role in defeating the German army and thus winning the First World War. This 'Hundred Days' campaign (August to November 1918) was the greatest series of land victories in British military history. 1918 also saw the creation of the Royal Air Force, the world's first independent air service, from the Royal Flying Corps and the Royal Naval Air Service. Until recently, British histories of the First World War have tended to concentrate on the earlier battles of 1916 and 1917 and often underplayed this vitally important period. Changing War fills this significant gap in our knowledge by providing in-depth examinations of key aspects of the operations of the British Army, the Royal Air Force and its antecedents in the climactic year of the First World War. Written by a group of established historians and emerging scholars it sheds light not only on 1918, but on the revolutionary changes in warfare that took place at that time.

This work argues that logistics in warfare is crucial to achieving strategic success. The author identifies logistical capabilities as an arbiter of opportunity, which plays a critical role in determining which side will hold the strategic iniative in war. Armies which have secured reliable resources of supply have a great advantage in determining the time and manner in which engagements take place. Often, they can fight in ways their opponents cannot. The author illustrates this point with case studies of British logistics during the Burma campaign in the World War II, American logistical innovations during the Pacific War, Communist supply methods during the American phase of the Vietnam War and the competing logistical systems of both NATO and Warsaw Pact conventional forces during the Cold War.
