Available in PDF, EPUB and Kindle. Book excerpt: "What men will fight for seems to be worth looking into," H. L. Mencken noted shortly after the close of the First World War. Prior to that war, although many military commanders and theorists had throughout history shown an aptitude for devising maxims concerning esprit de corps, fighting spirit, morale, and the like, military organizations had rarely sought either to understand or to promote combat motivation. For example, an officer who graduated from the Royal Military College (Sandhurst) at the end of the nineteenth century later commented that the art of leadership was utterly neglected (Charlton 1931, p. 48), while General Wavell recalled that during his course at the British Staff College at Camberley (1909-1 0) insufficient stress was laid "on the factor of morale, or how to induce it and maintain it'' (quoted in Connell1964, p. 63). The First World War forced commanders and staffs to take account of psychological factors and to anticipate wideJy varied responses to the combat environment because, unlike most previous wars, it was not fought by relatively small and homogeneous armies of regulars and trained reservists. The mobilization by the belligerents of about 65 million men (many of whom were enrolled under duress), the evidence of fairly widespread psychiatric breakdown, and the postwar disillusion (- xiii xiv PREFACE emplified in books like C. E. Montague's Disenchantment, published in 1922) all tended to dispel assumptions and to provoke questions about mo tivation and morale.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: “A fascinating study exploring the motivation of French soldiers during the Napoleonic Era, and the process through which they became Napoleon’s men.”—Frederick C. Schneid, author of Napoleon’s Conquest of Europe The men who fought in Napoleon’s Grande Armée built a new empire that changed the world. Remarkably, the same men raised arms during the French Revolution for liberté, égalité, and fraternité. In just over a decade, these freedom fighters, who had once struggled to overthrow tyrants, rallied to the side of a man who wanted to dominate Europe. What was behind this drastic change of heart? In this ground-breaking study, Michael J. Hughes shows how Napoleonic military culture shaped the motivation of Napoleon’s soldiers. Relying on extensive archival research and blending cultural and military history, Hughes demonstrates that the Napoleonic regime incorporated elements from both the Old Regime and French Revolutionary military culture to craft a new military culture, characterized by loyalty to both Napoleon and the preservation of French hegemony in Europe. Underscoring this new, hybrid military culture were five sources of motivation: honor, patriotism, a martial and virile masculinity, devotion to Napoleon, and coercion. Forging Napoleon’s Grande Armée vividly illustrates how this many-pronged culture gave Napoleon’s soldiers reasons to fight. “Hughes offers a tight and well-grounded exposition and analysis of French military culture in the Napoleonic period in which military honour is presented as a dynamic element.” —Journal of European Studies “Hughes’s book not only contributes to our understanding of the military success of Napoleon’s army, but also elegantly employs cultural history methods to better understand army operations and sustained troop motivations.” —Julia Osman, History: Reviews of New Book

Available in PDF, EPUB and Kindle. Book excerpt: Romania's Holy War rights the widespread myth that Romania was a reluctant member of the Axis during World War II. In correcting this fallacy, Grant T. Harward shows that, of an estimated 300,000 Jews who perished in Romania and Romanian-occupied Ukraine, more than 64,000 were, in fact, killed by Romanian soldiers. Moreover, the Romanian Army conducted a brutal campaign in German-occupied Ukraine, resulting in the deaths of thousands of Soviet prisoners of war, partisans, and civilians. Investigating why Romanian soldiers fought and committed such atrocities, Harward argues that strong ideology—a cocktail of nationalism, religion, antisemitism, and anticommunism—undergirded their motivation. Romania's Holy War draws on official military records, wartime periodicals, soldiers' diaries and memoirs, subsequent war crimes investigations, and recent interviews with veterans to tell the full story. Harward integrates the Holocaust into the narrative of military operations to show that most soldiers fully supported the wartime dictator, General Ion Antonescu, and his regime's holy war against "Judeo-Bolshevism." The army perpetrated mass reprisals, targeting Jews in liberated Romanian territory; supported the deportation and concentration of Jews in camps or ghettos in Romanian-occupied Soviet territory; and played a key supporting role in SS efforts to exterminate Jews in German-occupied Soviet territory. Harward proves that Romania became Nazi Germany's most important ally in the war against the USSR because its soldiers were highly motivated, thus overturning much of what we thought we knew about this theater of war. Romania's Holy War provides the first complete history of why Romanian soldiers fought on the Eastern Front.

Book excerpt: A People's Army documents the many distinctions between British regulars and Massachusetts provincial troops during the Seven Years' War. Originally published by UNC Press in 1984, the book was the first investigation of colonial military life to give equal attention to official records and to the diaries and other writings of the common soldier. The provincials' own accounts of their experiences in the campaign amplify statistical profiles that define the men, both as civilians and as soldiers. These writings reveal in intimate detail their misadventures, the drudgery of soldiering, the imminence of death, and the providential world view that helped reconcile them to their condition and to the war.

Book excerpt: In historical writing on World War I, Czech-speaking soldiers serving in the Austro-Hungarian military are typically studied as Czechs, rarely as soldiers, and never as men. As a result, the question of these soldiers’ imperial loyalties has dominated the historical literature to the exclusion of any debate on their identities and experiences. Men under Fire provides a groundbreaking analysis of this oft-overlooked cohort, drawing on a wealth of soldiers’ private writings to explore experiences of exhaustion, sex, loyalty, authority, and combat itself. It combines methods from history, gender studies, and military science to reveal the extent to which the Great War challenged these men’s senses of masculinity, and to which the resulting dynamics influenced their attitudes and loyalties.

Available in PDF, EPUB and Kindle. Book excerpt: The Mumbai blasts of 1993, the attack on the Indian Parliament in 2001, Mumbai 26/11—cross-border terrorism has continued unabated. What can India do to motivate Pakistan to do more to prevent such attacks? In the nuclear times that we live in, where a military counter-attack could escalate to destruction beyond imagination, overt warfare is clearly not an option. But since outright peace-making seems similarly infeasible, what combination of coercive pressure and bargaining could lead to peace? The authors provide, for the first time, a comprehensive assessment of the violent and non-violent options available to India for compelling Pakistan to take concrete steps towards curbing terrorism originating in its homeland. They draw on extensive interviews with senior Indian and Pakistani officials, in service and retired, to explore the challenges involved in compellence and to show how non-violent coercion combined with clarity on the economic, social and reputational costs of terrorism can better motivate Pakistan to pacify groups involved in cross-border terrorism. Not War, Not Peace? goes beyond the much discussed theories of nuclear deterrence and counterterrorism strategy to explore a new approach to resolving old conflicts.

Book excerpt: ADP 6-22 describes enduring concepts of leadership through the core competencies and attributes required of leaders of all cohorts and all organizations, regardless of mission or setting. These principles reflect decades of experience and validated scientific knowledge.An ideal Army leader serves as a role model through strong intellect, physical presence, professional competence, and moral character. An Army leader is able and willing to act decisively, within superior leaders' intent and purpose, and in the organization's best interests. Army leaders recognize that organizations, built on mutual trust and confidence, accomplish missions. Every member of the Army, military or civilian, is part of a team and functions in the role of leader and subordinate. Being a good subordinate is part of being an effective leader. Leaders do not just lead subordinates-they also lead other leaders. Leaders are not limited to just those designated by position, rank, or authority.

Book excerpt: WINNER OF THE NATIONAL BOOK CRITICS CIRCLE AWARD • AN AMERICAN BOOK AWARD FINALIST • A monumental history that has been hailed by The New York Times as “one of the most original and important books to be written about the war between Japan and the United States.” In this monumental history, Professor John Dower reveals a hidden, explosive dimension of the Pacific War—race—while writing what John Toland has called “a landmark book ... a powerful, moving, and evenhanded history that is sorely needed in both America and Japan.” Drawing on American and Japanese songs, slogans, cartoons, propaganda films, secret reports, and a wealth of other documents of the time, Dower opens up a whole new way of looking at that bitter struggle of four and a half decades ago and its ramifications in our lives today. As Edwin O. Reischauer, former ambassador to Japan, has pointed out, this book offers “a lesson that the postwar generations need most ... with eloquence, crushing detail, and power.”

Book excerpt: They were collectively known as “The Rock.” For one year, in 2007-2008, Sebastian Junger accompanied 30 men—a single platoon—from the storied 2nd battalion of the U.S. Army as they fought their way through a remote valley in eastern Afghanistan.Over the course of five trips, Junger was in more firefights than he could count, as men he knew were killed or wounded and he himself was almost killed. His relationship with these soldiers grew so close that they considered him part of the platoon, and he enjoyed an access and a candidness that few, if any, journalists ever attain. War is a narrative about combat: the fear of dying, the trauma of killing and the love between platoon-mates who would rather perish than let each other down. Gripping, honest and intense, War explores the neurological, psychological and social elements of combat, as well as the incredible bonds that form between these small groups of men. This is not a book about Afghanistan or the “War on Terror”; it is a book about all men, in all wars. Junger set out to answer what he thought of as the “hand-grenade question”: why would a man throw himself on a hand grenade to save other men he has known for probably only a few months? The answer is elusive but profound, going to the heart of what it means not just to be a soldier, but to be human.

Book excerpt: "...an engaging and enlightening account from which we all can benefit."—The Wall Street Journal A better way to combat knee-jerk biases and make smarter decisions, from Julia Galef, the acclaimed expert on rational decision-making. When it comes to what we believe, humans see what they want to see. In other words, we have what Julia Galef calls a "soldier" mindset. From tribalism and wishful thinking, to rationalizing in our personal lives and everything in between, we are driven to defend the ideas we most want to believe—and shoot down those we don't. But if we want to get things right more often, argues Galef, we should train ourselves to have a "scout" mindset. Unlike the soldier, a scout's goal isn't to defend one side over the other. It's to go out, survey the territory, and come back with as accurate a map as possible. Regardless of what they hope to be the case, above all, the scout wants to know what's actually true. In The Scout Mindset, Galef shows that what makes scouts better at getting things right isn't that they're smarter or more knowledgeable than everyone else. It's a handful of emotional skills, habits, and ways of looking at the world—which anyone can learn. With fascinating examples ranging from how to survive being stranded in the middle of the ocean, to how Jeff Bezos avoids overconfidence, to how superforecasters outperform CIA operatives, to Reddit threads and modern partisan politics, Galef explores why our brains deceive us and what we can do to change the way we think.

Available in PDF, EPUB and Kindle. Book excerpt: The Motivation Manifesto is a poetic and powerful call to reclaim your life and find your own personal freedom from Brendon Burchard – the world’s #1 high performance coach and #1 New York Times bestselling author of High Performance Habits. “It’s a triumphant work that transcends the title, lifting the reader from mere motivation into a soaringly purposeful and meaningful life. I love this book." —Paulo Coelho The Motivation Manifesto is a call to claim our personal power. World-renowned high performance trainer Brendon Burchard reveals that the main motive of humankind is the pursuit of greater Personal Freedom. We desire the grand liberties of choice—time freedom, emotional freedom, social freedom, financial freedom, spiritual freedom. Only two enemies stand in our way: an external enemy, defined as the social oppression of who we are by the mediocre masses, and an internal enemy, a sort of self-oppression caused by our own doubt and fear. The march to Personal Freedom, Brendon says, can be won only by declaring our intent and independence, stepping into our personal power, and battling through self-doubt and the distractions of the day until full victory is won. Recalling the revolutionist voices of the past that chose freedom over tyranny, Brendon motivates us to free ourselves from fear and take back our lives once and for all. In this life-changing personal growth book, Brendon presents his nine declarations for personal power and motivation, drawing on insights from his own personal journey and from the lives of some of history's greatest leaders and thinkers. Each chapter focuses on one of the nine declarations, offering practical strategies and exercises to help you apply these principles to your life. Whether you're seeking to overcome self-doubt, boost your confidence, or achieve your goals, The Motivation Manifesto is an invaluable guide to unlocking your full potential. With its inspiring message and actionable advice, this bestselling book is a must-read for anyone who wants to unleash their inner greatness with the power of determination, resilience, and an empowering mindset.

Available in PDF, EPUB and Kindle. Book excerpt: An updated edition of the blockbuster bestselling leadership book that took America and the world by storm, two U.S. Navy SEAL officers who led the most highly decorated special operations unit of the Iraq War demonstrate how to apply powerful leadership principles from the battlefield to business and life. Sent to the most violent battlefield in Iraq, Jocko Willink and Leif Babin’s SEAL task unit faced a seemingly impossible mission: help U.S. forces secure Ramadi, a city deemed “all but lost.” In gripping firsthand accounts of heroism, tragic loss, and hard-won victories in SEAL Team Three’s Task Unit Bruiser, they learned that leadership—at every level—is the most important factor in whether a team succeeds or fails. Willink and Babin returned home from deployment and instituted SEAL leadership training that helped forge the next generation of SEAL leaders. After departing the SEAL Teams, they launched Echelon Front, a company that teaches these same leadership principles to businesses and organizations. From promising startups to Fortune 500 companies, Babin and Willink have helped scores of clients across a broad range of industries build their own high-performance teams and dominate their battlefields. Now, detailing the mind-set and principles that enable SEAL units to accomplish the most difficult missions in combat, Extreme Ownership shows how to apply them to any team, family or organization. Each chapter focuses on a specific topic such as Cover and Move, Decentralized Command, and Leading Up the Chain, explaining what they are, why they are important, and how to implement them in any leadership environment. A compelling narrative with powerful instruction and direct application, Extreme Ownership revolutionizes business management and challenges leaders everywhere to fulfill their ultimate purpose: lead and win.

Book excerpt: In order to gain a clearer understanding of stress and its physical and psychological consequences, reversal theory takes into account the fact that many people need stress in their lives in order to operate. This text organizes stress and health research that has been undertaken within the reversal theory framework. The first two chapters outline and provide a focus about reversal theory, thus acting as a bridge to the rest of the text. For those new to reversal theory, tables and figures are included Which Summarize Some Of The Characteristics Of The Metamotivational states identified in the theory, and show how they can be applied systematically. The following section deals with the effects of stress, including: stressful events; academic stress; and back pain and work stress. It then tackles the subjects of the physiology and psychology of smoking and attempts to quit this sort of addiction, and the risk-taking behaviours of parachuting and unsafe sexual practice. Finally the book Examines Health-Promoting Behaviours And The Factors Which Facilitate Or inhibit them.
