General John A. Wickham, commander of the famous 101st Airborne Division in the 1970s and subsequently Army Chief of Staff, once visited Antietam battlefield. Gazing at Bloody Lane where, in 1862, several Union assaults were brutally repulsed before they finally broke through, he marveled, "You couldn't get American soldiers today to make an attack like that." Why did those men risk certain death, over and over again, through countless bloody battles and four long, awful years ? Why did the conventional wisdom -- that soldiers become increasingly cynical and disillusioned as war progresses -- not hold true in the Civil War? It is to this question--why did they fight--that James McPherson, America's preeminent Civil War historian, now turns his attention. He shows that, contrary to what many scholars believe, the soldiers of the Civil War remained powerfully convinced of the ideals for which they fought throughout the conflict. Motivated by duty and honor, and often by religious faith, these men wrote frequently of their firm belief in the cause for which they fought: the principles of liberty, freedom, justice, and patriotism. Soldiers on both sides harkened back to the Founding Fathers, and the ideals of the American Revolution. They fought to defend their country, either the Union--"the best Government ever made"--or the Confederate states, where their very homes and families were under siege. And they fought to defend their honor and manhood. "I should not lik to go home with the name of a couhard," one Massachusetts private wrote, and another private from Ohio said, "My wife would sooner hear of my death than my disgrace." Even after three years of bloody battles, more than half of the Union soldiers reenlisted voluntarily. "While duty calls me here and my country demands my services I should be willing to make the sacrifice," one man wrote to his protesting parents. And another soldier said simply, "I still love my country." McPherson draws on more than 25,000 letters and nearly 250 private diaries from men on both sides. Civil War soldiers were among the most literate soldiers in history, and most of them wrote home frequently, as it was the only way for them to keep in touch with homes that many of them had left for the first time in their lives. Significantly, their letters were also uncensored by military authorities, and are uniquely frank in their criticism and detailed in their reports of marches and battles, relations between officers and men, political debates, and morale. For Cause and Comrades lets these soldiers tell their own stories in their own words to create an account that is both deeply moving and far truer than most books on war. Battle Cry of Freedom, McPherson's Pulitzer Prize-winning account of the Civil War, was a national bestseller that Hugh Brogan, in The New York Times, called "history writing of the highest order." For Cause and Comrades deserves similar accolades, as McPherson's masterful prose and the soldiers' own words combine to create both an important book on an often-overlooked aspect of our bloody Civil War, and a powerfully moving account of the men who fought it.

Now in a thoroughly revised and updated edition, this classic text presents a comprehensive survey of the many alternative theories that attempt to explain the causes of interstate war. For each theory, Greg Cashman examines the arguments and counterarguments, considers the empirical evidence and counterevidence generated by social-science research, looks at historical applications of the theory, and discusses the theory’s implications for restraining international violence. Among the questions he explores are: Are humans aggressive by nature? Do individual differences among leaders matter? How might poor decision making procedures lead to war? Why do leaders engage in seemingly risky and irrational policies that end in war? Why do states with internal conflicts seem to become entangled in wars with their neighbors? What roles do nationalism and ethnicity play in international conflict? What kinds of countries are most likely to become involved in war? Why have certain pairs of countries been particularly war-prone over the centuries? Can strong states deter war? Can we find any patterns in the way that war breaks out? How do balances of power or changes in balances of power make war more likely? Do social scientists currently have an answer to the question of what causes war? Cashman examines theories of war at the individual, substate, nation-state, dyadic, and international systems level of analysis. Written in a clear and accessible style, this interdisciplinary text will be essential reading for all students of international relations.

Public consciousness of the threat of nuclear war is rising steadily. Responses to the nuclear dilemma are conflicting and often confusing. Never have we been more in need of information and perspective, for if we wish to avoid war we must understand it. Michael Howard offers an analysis of our present predicament by discussing those issues that cause war and make peace. His book includes an examination of nuclear strategy today, views of the past about the conduct of international relations, ethics, modes of defense, and studies of military thinkers and leaders. The Causes of Wars illuminates the interrelationship between men and ideas, between war and other social forces, and between our present situation and its roots in the past.

What makes wars drag on and why do they end when they do? Here H. E. Goemans brings theoretical rigor and empirical depth to a long-standing question of securities studies. He explores how various government leaders assess the cost of war in terms of domestic politics and their own postwar fates. Goemans first develops the argument that two sides will wage war until both gain sufficient knowledge of the other's strengths and weaknesses so as to agree on the probable outcome of continued war. Yet the incentives that motivate leaders to then terminate war, Goemans maintains, can vary greatly depending on the type of government they represent. The author looks at democracies, dictatorships, and mixed regimes and compares the willingness among leaders to back out of wars or risk the costs of continued warfare. Democracies, according to Goemans, will prefer to withdraw quickly from a war they are not winning in order to appease the populace. Autocracies will do likewise so as not to be overthrown by their internal enemies. Mixed regimes, which are made up of several competing groups and which exclude a substantial proportion of the people from access to power, will likely see little risk in continuing a losing war in the hope of turning the tide. Goemans explores the conditions and the reasoning behind this "gamble for resurrection" as well as other strategies, using rational choice theory, statistical analysis, and detailed case studies of Germany, Britain, France, and Russia during World War I. In so doing, he offers a new perspective of the Great War that integrates domestic politics, international politics, and battlefield developments.

Is peace an aberration? The New York Times bestselling author of Paris 1919 offers a provocative view of war as an essential component of humanity. NAMED ONE OF THE TEN BEST BOOKS OF THE YEAR BY THE NEW YORK TIMES BOOK REVIEW “Margaret MacMillan has produced another seminal work. . . . She is right that we must, more than ever, think about war. And she has shown us how in this brilliant, elegantly written book.”—H.R. McMaster, author of Dereliction of Duty and Battlegrounds: The Fight to Defend the Free World The instinct to fight may be innate in human nature, but war—organized violence—comes with organized society. War has shaped humanity’s history, its social and political institutions, its values and ideas. Our very language, our public spaces, our private memories, and some of our greatest cultural treasures reflect the glory and the misery of war. War is an uncomfortable and challenging subject not least because it brings out both the vilest and the noblest aspects of humanity. Margaret MacMillan looks at the ways in which war has influenced human society and how, in turn, changes in political organization, technology, or ideologies have affected how and why we fight. War: How Conflict Shaped Us explores such much-debated and controversial questions as: When did war first start? Does human nature doom us to fight one another? Why has war been described as the most organized of all human activities? Why are warriors almost always men? Is war ever within our control? Drawing on lessons from wars throughout the past, from classical history to the present day, MacMillan reveals the many faces of war—the way it has determined our past, our future, our views of the world, and our very conception of ourselves.
