In this gripping collection of first-hand accounts, Ian Knight presents the adventure of nineteenth-century warfare - from the thrill of the cavalry charges at Balaklava and Omdurman, to the terror of battle against an overwhelming odds such as Rorke's Drift - in the words of the men actually there. These eyewitness accounts provide a vivid and sometimes shocking insight into the brutal realities of warfare for the British imperial soldier, who fought against enemies from massed ranks of Russians and assegai-armed natives to sharp-shooting Boers, in often the most terrible conditions imaginable. These stirring tales of military adventure have been edited by Ian Knight and brought together and published in book form. Originally featured in turn-of-the-century magazine, popular during the heyday of empire, these historically valuable accounts throw considerable light on campaign conditions during Queen Victoria's colonial wars. Marching to the Drums includes accounts focusing on the experience of battle during such pivotal conflicts as the Sikh Wars, the Crimean War, the Afghan Wars, the Anglo-Zulu War, and those in China, the Sudan and South Africa.

"The collapse of the Red Army was one of the most spectacular in human history, and also one of the most mysterious. Neither Soviet nor Russian armed forces suffered catastrophic losses on the battlefield, while Russian soldiers became more involved, not less, in politics in post-Soviet Russia. Through a sophisticated application of institutional theory to a rich collection of data, Zoltan Barany unravels this mystery in a compelling and masterful way. This book will become a classic on Russian civil-military relations, while also adding much to our understanding of Russian politics more generally."--Michael McFaul, Stanford University

"Zoltan Barany is one of the most wide-ranging and thoughtful scholars writing on postcommunist politics today. Here, he provides a fascinating look at one of the most important issues in contemporary Russia. The link Barany makes between the condition of the military and the character of the postcommunist political regime is especially interesting. This book will appeal to policymakers and observers of Russian politics both inside and outside academia."--M. Steven Fish, University of California, Berkeley, and author of "Democracy Derailed in Russia"

"This book marks a new approach to the study of civil-military relations in Russia. It does something no one has done to date--it explains why Russian civil-military relations are not only not democratic, but are moving in the opposite direction. It also highlights the incredibly important roles that Gorbachev, Yeltsin, and Putin have played in the evolution of such relations."--Dale Herspring, Kansas State University

"This is political science at its best: a lucid explanation of an important puzzle, systematically approached but mindful of the crucial role of human interaction. Barany makes a valuable contribution to our understanding of the Russian military, the state of Russian democracy, and to the larger issue of civil-military relations and democracy in general."--Thomas Nichols, United States Naval War College

The modern US Army as we know it was largely created in the years between the two world wars. Prior to World War I, officers in leadership positions were increasingly convinced that building a new army could not take place as a series of random developments but was an enterprise that had to be guided by a distinct military policy that enjoyed the support of the nation. In 1920, Congress accepted that idea and embodied it in the National Defense Act. In doing so it also accepted army leadership's idea of entrusting America's security to a unique force, the Citizen Army, and tasked the nation's Regular Army with developing and training that force. Creating the Modern Army details the efforts of the Regular Army to do so in the face of austerity budgets and public apathy while simultaneously responding to the challenges posed by the new and revolutionary mechanization of warfare. In this book Woolley focuses on the development of what he sees as the four major features of the modernized army that emerged due to these efforts. These included the creation of the civilian components of the new army: the Citizen's Military Training Camps, the Officer Reserve Corps, the National Guard, and the Reserve Officer Training Corps; the development of the four major combat branches as the structural basis for organizing the army as well as creating the means to educate new officers and soldiers about their craft and to socialize them into an army culture; the creation of a rationalized and progressive system of professional military education; and the initial mechanization of the combat branches. Woolley also points out how the development of the army in this period was heavily influenced by policies and actions of the president and Congress. The US Army that fought World War II was clearly a citizen army whose leadership was largely trained within the framework of the institutions of the army created by the National Defense Act. The way that army fought the war may have been less decisive and more costly in terms of lives and money than it should have been. But that army won the war and therefore validated the citizen army as the US way of war.

Is it legal to kill, or capture and confine, someone in war? Is this relevant or wise to ask in the reality of war? What does 'legal' actually mean in the labyrinth of overlapping international laws? This volume explores the meaning, relevance, and wisdom of questioning the 'legality' of the use of force against individuals in war by reconnecting legal thought with the social world. Weaving together law, social theories, and actual practices, the book presents an interdisciplinary study of the laws regulating warfare. The Use of Force against Individuals in War under International Law uncovers different conceptions of 'legality' that generate tensions among different international laws regulating warfare and highlights the limits of legal techniques in addressing these tensions. Accepting these tensions serves not to denigrate the law itself but to invite a deeper level of engagement with it - through the lens of social theories. Drawing on the insight that every social action results from an interaction between human agency and social structures, this publication argues that in regulating warfare, one distinct body of international law, the law of armed conflicts, accommodates the diminished agency of human beings operating in highly structured conditions while other bodies of international law harbour the potential to transform these very structured conditions. Thus, assimilating these laws, whether in court or real-world practices, fundamentally conflates their underlying social ontologies.

The charge of the Army Research Laboratory Technical Assessment Board (ARLTAB) is to provide biennial assessments of the scientific and technical quality of the research, development, and analysis programs at the Army Research Laboratory (ARL). The ARLTAB is assisted by six panels, each of which focuses on the portion of the ARL program conducted by one of ARL's six directorates1. When requested to do so by ARL, the ARLTAB also examines work that cuts across the directorates. For example, during 2011-2012, ARL requested that the ARLTAB examine crosscutting work in the areas of autonomous systems and network science. The overall quality of ARL's technical staff and their work continues to be impressive. Staff continue to demonstrate clear, passionate mindfulness of the importance of transitioning technology to support immediate and longer-term Army needs. Their involvement with the wider scientific and engineering community continues to expand. Such continued involvement and collaboration are fundamentally important for ARL's scientific and technical activities and need to include the essential elements of peer review and interaction through publications and travel to attend professional meetings, including international professional meetings. In general, ARL is working very well within an appropriate research and development niche and has been demonstrating significant accomplishments, as exemplified in the following discussion, which also addresses opportunities and challenges.

In the past 15 years, UK anti-militarist activists have auctioned off a tank outside an arms fair, superglued themselves to Lockheed Martin's central London offices and stopped a battleship with a canoe. They have also challenged militarism in many other everyday ways. This book explores why anti-militarists resist, considers the politics of different tactics and examines the tensions and debates within the movement. As it explores the multifaceted, imaginative and highly subversive world of anti-militarism, the book also makes two overarching arguments. First, that anti-militarists can help us to understand militarism in new and useful ways. And secondly, that the methods and ideas used by anti-militarists can be a potent force for radical political change.

Laura Sjoberg positions gender and gender subordination as key factors in the making and fighting of global conflict. Through the lens ofgender, she examines the meaning, causes, practices, and experiences of war, building a more inclusive approach to the analysis of violent conflict between states.

Considering war at the international, state, substate, and individual levels, Sjoberg's feminist perspective elevates a number of causal variables in war decision-making. These include structural gender inequality, cycles of gendered violence, state masculine posturing, the often overlooked role of emotion in political interactions, gendered understandings of power, and states' mistaken perception of their own autonomy and unitary nature. "Gendering Global Conflict" also calls attention to understudied spaces that can be sites of war, such as the workplace, the household, and even the bedroom. Her findings show gender to be a linchpin of even the most tedious and seemingly bland tactical and logistical decisions in violent conflict. Armed with that information, Sjoberg undertakes the task of redefining and reintroducing critical readings of war's political, economic, and humanitarian dimensions, developing the beginnings of a feminist theory of war.

Exploring how the U.S. military can move beyond Iraq and Afghanistan.Since the September 11, 2001, attacks, the U.S. military has been fighting incessantly in conflicts around the globe, but with inconclusive results. The legacy of this long involvement in war without end includes a military that is bitter and frustrated. The public is disinterested. The national security apparatus seeks to pivot away from these engagements and to move on to the next threats - notably those emanating from China and Russia. At best there are ad hoc, unstructured debates about Iraq or Afghanistan. Many young Americans question whether it even makes sense to invest in the military. Simply put, there has been no serious, organized stocktaking by the public, politicians, opinion leaders, or the military itself of this inheritance. Despite its lengthy warfighting experience and high-technology weapons, the military is woefully unprepared for future wars because of this conflicted legacy and uncertainty about the future security environment. But the United States cannot simply hit the reset button.If the U.S. military seeks to win in the future, it must acknowledge and reconcile with the inheritance of its long and failed wars. This book seeks to help them do so.

The threat to the survival of humankind posed by nuclear weapons has been a frightening and essential focus of public debate for the last four decades and must continue to be so if we are to avoid destroying ourselves and the natural world around us. One unfortunate result of preoccupation with the nuclear threat, however, has been a new kind of "respectability" accorded to conventional war. In this radical and cogent argument for pacifism, Robert Holmes asserts that all war--not just nuclear war--has become morally impermissible in the modern world. Addressing a wide audience of informed and concerned readers, he raises dramatic questions about the concepts of "political realism" and nuclear deterrence, makes a number of persuasive suggestions for nonviolent alternatives to war, and presents a rich panorama of thinking about war from St. Augustine to Reinhold Niebuhr and Herman Kahn.

Holmes's positions are compellingly presented and will provoke discussion both among convinced pacifists and among those whom he calls "militarists." "Militarists," we realize after reading this book, include the majority of us who live a friendly and peaceful personal life while supporting a system which, if Holmes is correct, guarantees war and risks eventual human extinction.

A new edition of von Clausewitz's classic treatise on military strategy, reinterpreted by Graham Harman through the philosophy of speculative realism.

Prussian General Carl von Clausewitz famously wrote that War is the continuation of politics by other means . But what does Clausewitz mean to a world where economic, political and cultural conflicts are increasingly framed as wars? Written after the Napoleonic Wars but left unfinished at the author s death and not published until 1832, On War is one of the most influential and important works on military strategy ever written.

This new edition presents this classic text with a new introduction by Graham Harman, who reads Clausewitz s ideas about war, politics and military strategy through the lens of speculative realism.

The risks of arms control and disarmament, how they can be reduced or eliminated, and the political implications of drastic disarmament are analyzed by eleven experts. Emphasis is placed on the development of techniques for disarming that are politically feasible and give reasonable assurance to each side that the other is not violating its obligations for any serious reason. Three major aspects of the problem are considered: how to get the disarmament process started, and once started to continue it how to retain the freedom of diplomatic action that might be needed to defend national interests; and how to approach the problems of political security in a fully disarmed world.

Azar Gat sets out to resolve one of the age-old questions of human existence: why people fight and can they stop. Spanning warfare from prehistory to the 21st century, the book shows that, neither an irresistible drive nor a cultural invention, deadly violence and warfare have figured prominently in our behavioural toolkit since the dawn of our species. People have always alternated between cooperation, peaceful competition, and violence to attain evolution-shaped human desires. A marked shift in the balance between these options has occurred since the onset of the industrial age. Rather than modern war becoming more costly (it hasn't), it is peace that has become more rewarding. Scrutinizing existing theories concerning the decline of war - such as the 'democratic peace' and 'capitalist peace' - Gat shows that they in fact partake of a broader Modernization Peace that has been growing since 1815. By now, war has disappeared within the world's most developed areas. Finally, Gat explains why the Modernization Peace has been disrupted in the past, as during the two World Wars, and how challenges to it may still arise. They include claimants to alternative modernity - such as China and Russia - anti-modernists, and failed modernizers that may spawn terrorism, potentially unconventional. While the world has become more peaceful than ever before, there is still much to worry about in terms of security and no place for complacency.

The rules have changed, and we are dangerously unprepared. In Goliath, former paratrooper and Professor of Strategy Sean McFate teaches us the ten new rules of war for today. __________ War is timeless. Some things change - weapons, tactics, leadership - but our desire to go into battle does not. We are living in an age of conflict: global terrorism, Russia's resurgence and China's rise, international criminal empires, climate change and dwindling natural resources. But while the West has been playing the same old war games, the enemy has changed the rules. Sean McFate has been on the front lines of conflict. He has seen first-hand the horrors of battle, and as a strategist, he understands the complexity of the current military situation. In this new age of war: - Technology will not save us - Victory will belong to the cunning, not the strong - Plausible deniability is more potent than firepower - New types of world powers will rule Learn how to triumph in the coming age of conflict in ten new rules.

Why do some countries choose to end wars short of total victory while others fight on, sometimes in the face of appalling odds? "How Wars End" argues that two central factors shape war-termination decision making: information about the balance of power and the resolve of one's enemy, and fears that the other side's commitment to abide by a war-ending peace settlement may not be credible.

Dan Reiter explains how information about combat outcomes and other factors may persuade a warring nation to demand more or less in peace negotiations, and why a country might refuse to negotiate limited terms and instead tenaciously pursue absolute victory if it fears that its enemy might renege on a peace deal. He fully lays out the theory and then tests it on more than twenty cases of war-termination behavior, including decisions during the American Civil War, the two world wars, and the Korean War. Reiter helps solve some of the most enduring puzzles in military history, such as why Abraham Lincoln issued the Emancipation Proclamation, why Germany in 1918 renewed its attack in the West after securing peace with Russia in the East, and why Britain refused to seek peace terms with Germany after France fell in 1940.

"How Wars End" concludes with a timely discussion of twentieth-century American foreign policy, framing the Bush Doctrine's emphasis on preventive war in the context of the theory.

An army, Lewis Mumford once observed, 'is a body of pure consumers' and it is logistics that feeds this body's insatiable appetite for men and materiel. Successful logistics - the transportation of supplies and combatants to battle - cannot guarantee victory, but poor logistics portends defeat. In Feeding Victory, Jobie Turner asks how technical innovation has affected this connection over time and whether advances in technology, from the railroad and the airplane to the nuclear weapon and the computer, have altered both the critical relationship between logistics and warfare and, ultimately, geopolitical dynamics. Covering a span of three hundred years, Feeding Victory focuses on five distinct periods of technological change, from the preindustrial era to the information age. For each era Turner presents a case study: the campaign for Lake George from 1755 to 1759, the Western Front in 1917, the Battle of Guadalcanal in 1942, the Battle of Stalingrad from 1942 to 1943, and the Battle of Khe Sanh in 1968. In each of these cases the logistics of the belligerents were at their limit because of geography or the vast material needs of war. With such limits, the case studies both give a clear accounting of the logistics of the period, particularly with respect to the mode of transportation - whether air, land, or sea - and reveal the inflection points between success and failure. What are the continuities between eras, Turner asks, and what can these campaigns tell us about the relationship of technology to logistics and logistics to geopolitics? In doing so, Turner discovers just how critical the biological needs of the soldiers on the battlefield prove to be; in fact, they overwhelm firepower in their importance, even in the modern era. His work shows how logistics aptly represents technological shifts from the enlightenment to the dawn of the twenty-first century and how, in our time, ideas have come to trump the material forces of war.

Despite the disasters of Iraq, Afghanistan, Syria and ever more visible evidence of the horrors of war, the concepts of 'Humanitarian Intervention' and 'Just War' enjoy widespread legitimacy and continue to exercise an unshakeable grip on our imaginations. Robin Dunford and Michael Neu provide a clear and comprehensive critique of both Just War Theory and the Responsibility to Protect (R2P) doctrine, deconstructing the philosophical, moral and political arguments that underpin them. In doing so, they show how proponents of Just War and R2P have tended to treat killing in a way which obscures the complex and often messy reality of war, and pays little heed to the human impact of such conflicts. Going further, they provide answers to such difficult questions as 'Surely it would have been just for us to intervene in the Rwandan genocide?' An essential guide to one of the most difficult moral and political issues of our age.

This book examines the U. S. Army's presence in Germany after the Nazi regime's capitulation in May 1945. This presence required the pursuit of two stated missions: to secure German borders, and to establish an occupation government within the assigned U.S. zone and sector of Berlin. Both missions required logistics support, a critical aspect often understated in existing scholarship. The security mission, covered by the combat troops, declined between 1945 and 1948, but grew again with the Berlin Blockade/Airlift in 1948, and then again with the Korean crisis in 1950. The logistics mission grew exponentially to support this security mission, as the U.S. Army was the only U.S. Government agency possessing the ability and resources to initially support the occupation mission in Germany. The build-up of 'Little Americas' during the occupation years stood forward-deployed U.S. military forces in Europe in good stead over the ensuing decades.

The unmarked mass graves left by war and acts of terror are lasting traces of violence in communities traumatized by fear, conflict, and unfinished mourning. Like silent testimonies to the wounds of history, these graves continue to inflict harm on communities and families that wish to bury or memorialize their lost kin. Changing political circumstances can reveal the location of mass graves or facilitate their exhumation, but the challenge of identifying and recovering the dead is only the beginning of a complex process that brings the rights and wishes of a bereaved society onto a transnational stage. Necropolitics: Mass Graves and Exhumations in the Age of Human Rights examines the political and social implications of this sensitive undertaking in specific local and national contexts. International forensic methods, local-level claims, national political developments, and transnational human rights discourse converge in detailed case studies from the United States, Argentina, Chile, Peru, Spain, Bosnia-Herzegovina, Greece, Rwanda, Cambodia, and Korea. Contributors analyze the role of exhumations in transitional justice from the steps of interviewing eyewitnesses and survivors to the painstaking forensic recovery and comparison of DNA profiles. This innovative volume demonstrates that contemporary exhumations are as much a source of personal, historical, and criminal evidence as instruments of redress for victims through legal accountability and memory politics.

Where the implications of war and peace are open to question, the possibility of change depends more on politics than economics. This book asks whether the region's great powers can overcome opposing interests and commit to political restraint. The concept of regional security is based on great power support for regional order. However, there are many pitfalls to consider: notably, the politics of contested nationalisms; the Asia-Pacific rivalry of China and the US; and India's inclinations to function - or be seen - as a benevolent hegemon for the region. Yet there are signs of renewed determination to move the region in new directions. While China's Silk Road projects are long-term regional investments that hinge on regional stability, the US is attempting to fashion new partnerships and India strives to reconcile regional differences to promote a peaceful environment.This book, as it sets out the emerging agendas of the great powers and local powers, makes a significant contribution to a better understanding of the international relations and diplomatic politics of South Asia.
