The British Army during World War I fought the largest and most costly war in its long history. Unlike the French and German Armies, its units were made up exclusively of volunteers—as opposed to conscripts—at the beginning of the conflict. Furthermore, the British Army was considerably smaller than its French and German counterparts. Yet the army showed exemplary valour and courage on the battlefield. Buchan and Newbolt bring their expert analysis into their overview of the Great War and the reasons for it. John Buchan (1875-1940) was a Scottish novelist, historian and also served as Canada's Governor General. With the outbreak of the First World War, Buchan worked as a correspondent in France for The Times. Sir Henry John Newbolt (1862–1938) was an English poet, novelist and historian. He also had a very powerful role as a government adviser. He is perhaps best remembered for his poems "Vitaï Lampada" and "Drake's Drum".
