John Churchill, the Duke of Marlborough (1644-1722), was one of the greatest military commanders and statesmen in the history of England. Victorious in the Battles of Blenheim (1704) and Ramillies (1706) and countless other campaigns, Marlborough, whose political intrigues were almost as legendary as his military skill, never fought a battle he didn't win. Marlborough also bequeathed the world another great British military strategist and diplomat, his descendant, Winston S. Churchill.

While staying closely aligned with Hitler, Mussolini remained carefully neutral until the summer of 1940. Then, with the wholly unexpected and sudden collapse of the French and British armies, Mussolini declared war on the Allies in the hope of making territorial gains in Southern France and Africa. This decision proved a horrifying miscalculation, dooming Italy to its own prolonged and unwinnable war, immense casualties and an Allied invasion in 1943 which ushered in a terrible new era for the country.

The Mongol army led by Genghis Khan subjugated more lands and people in 25 years than the Romans did in 400. In nearly every country the Mongols conquered, they brought an unprecedented rise in cultural communication, expanded trade, and a blossoming of civilization.

Taking us from the French Revolution to the Cold War and the Falklands, Andrew Roberts presents us with a bracingly honest and insightful look at nine major figures in modern history: Napoleon Bonaparte, Horatio Nelson, Winston Churchill, Adolf Hitler, Joseph Stalin, George C. Marshall, Charles de Gaulle, Dwight D. Eisenhower and Margaret Thatcher. Each of these leaders fundamentally shaped the outcome of the war their nation was embroiled in. How were they alike, and in what ways did they differ? 

Between 1861 and 1865, the clash of the greatest armies the Western hemisphere had ever seen turned small towns, little-known streams, and obscure meadows in the American countryside into names we will always remember. In those great battles, those streams ran red with blood-and the United States was truly born.
