The object of this book is to introduce readers to a whole range of military history which has all the drama, dangers, horrors and excitement that we associate with Stalingrad or the Somme. Battles are acute moments of history whenever and wherever they have been fought. Through them we can understand how warfare and world history have evolved.Choosing just one hundred battles from recorded human history is a challenge. Not just because it is necessary to cover almost 6,000 years of history, but because men have fought each other almost continuously for millennia. Anyone who knows anything about the history of war may be disappointed at what has had to be left out. However, each of the 100 memorable battles described shows both how the nature of armed combat has changed over human history, and also how, despite changes in technology, organisation or ideas, many things have remained the same.It is an old adage that you can win a battle but lose a war. The battles featured here almost always resulted in victory for one side or another, but the victor did not necessarily win the war. Some battles are decisive in that broader historical sense, others are not. The further back in time, the more likely it is that an enemy could be finished off in one blow. The wars of the modern age, between major states, have involved repeated battles until one side was battered into submission. Some of the great generals of the recent past - Napoleon, Robert E Lee, Erich von Manstein - have been on the losing side but are remembered nonetheless for their generalship.Some on the winning side have all but disappeared from the history books or from public memory. Equally, in many battles, the issue is not victory or defeat, but what the battle can tell us about the history of warfare itself. New weapons, new tactics, new ways of organising armed forces can have a sudden impact on the outcome of a battle. But so too can leadership, or the effects of a clever deception, or raw courage. That is why the book has been divided up into clear themes which apply equally to the battles of the ancient world as they do to the battles of today.As Professor Richard Overy laments: "Battle is not a game to plug into a computer but a piece of living history, messy, bloody and real. That, at least, has not changed in 6,000 years."
