From the publisher: It started with a botched murder. By the time it ended over sixteen million people had lost their lives. Seventy million men took up arms, nine million of them never returned home. More than four times that number had been wounded. It was supposed to be the "war to end all wars." Instead the Great War began a cycle of violence that would shape the twentieth century. In this concise yet comprehensive history of World War I, the conduct of the war is reviewed; from the trenches of the Western Front to the frozen fields of the Eastern Front, from the war in the multiple theaters of the Middle East to the war in Africa, China, and the South Pacific. This was the first war fought in three dimensions, on land and sea, beneath the waves, and in the air. It heralded the beginning of air power and the emergence of submarine warfare.
