The essays brought together in this volume examine the conduct of war by the Angevin kings of England during the long thirteenth century (1189-1307). Drawing upon a wide range of unpublished administrative records that have been largely ignored by previous scholarship, David S. Bachrach offers new insights into the military technology of the period, including the types of artillery and missile weapons produced by the royal government. The studies in this volume also highlight the administrative sophistication of the Angevin kings in military affairs, showing how they produced and maintained huge arsenals, mobilized vast quantities of supplies for their armies in the field, and provided for the pastoral care of their men. Bachrach also challenges the knight-centric focus of much of the scholarship on this period, demonstrating that the militarization of the English population penetrated to men in the lower social and economic strata, who volunteered in large numbers for military service, and even made careers as professional soldiers.

Warfare in Medieval Europe, now in its second edition, offers considerably more attention to the transition from the later Roman Empire to the early Middle Ages, the composition of the armies of the opponents of the West, and the experience of commanders and individual combatants on the battlefield. This second revised and expanded edition provides a more in-depth thematic discussion of the nature and conduct of war, with an emphasis on its overall impact on society, from the late Roman Empire to the end of the Hundred Years' War. The authors explore the origins of the institutions, physical infrastructure, and intellectual underpinnings of warfare, with chapters on military topography, military technology, logistics, combat, and strategy. Bernard and David Bachrach have also added a new chapter, which provides two detailed campaign narratives that highlight the themes treated throughout the text. The geographical scope of the volume encompasses Latin Europe, the Slavic World, Scandinavia, and the eastern Mediterranean, with a particular focus on the conflict between Western Christianity and the Islamic Near East. Written in an accessible and engaging way, Warfare in Medieval Europe is the ideal resource for all students of the history of medieval warfare.

Highlights "the range and richness of scholarship on medieval warfare, military institutions, and cultures of conflict that characterize the field". History 95 (2010) Warfare on the periphery of Europe and across cultural boundaries is a particular focus of this volume. One article, on Castilian seapower, treats the melding of northern and southern naval traditions; another clarifies the military roles of the Ayyubid and Mamluk miners and stoneworkers in siege warfare; a third emphasizes cultural considerations in an Icelandic conflict; a fourth looks at how an Iberian prelate navigated the line between ecclesiastical and military responsibilities; and a fifth analyzes the different roles of early gunpowder weapons in Europe and China, linking technological history with the significance of human geography. Further contributions also consider technology, two dealing with fifteenth-century English artillery and the third with prefabricated mechanical artillery during the Crusades. Another theme of the volume is source criticism, with re-examinations of the sources for Owain Glyndwr's (possible) victory at Hyddgen in 1401, a (possible) Danish attack on England in 1128, and the role of non-milites in Salian warfare.

First commissioned by Bishop Gerard I of Cambrai (1012-1051) in 1023 or 1024, the Gesta episcoporum Cameracensium was the work of two authors, the second of whom completed the text shortly after the death of Bishop Gerard. The three books of the Gesta shed considerable light on the policies and actions of many of the key political and religious figures in an economically and intellectually vibrant region on the frontier between the German and French kingdoms. The Deeds of the Bishops of Cambrai, translated in this volume into English for the first time, provides unique insights into the relationship between the German king and the bishops within the context of the so-called imperial church system, the rise of both secular and ecclesiastical territorial lordships, the conduct of war, the cult of the saints, monastic reform, and evolving conceptions of the proper social order of society. Including extensive commentary, apparatus of explanatory notes, maps, genealogies, this text will be of considerable value both in undergraduate and graduate courses as well as to scholars.

Germany was the most powerful kingdom in the medieval West from the mid-tenth to the mid-thirteenth century. However, its history remains largely unknown outside of the German-speaking regions of modern Europe. Until recently, almost all of the sources for medieval Germany were available only in the original Latin or in German translations, while most scholarly investigation has been in German. The limited English-language scholarship has focused on royal politics and the aristocracy. Even today, English-speaking students will find very little about the lower social orders, or Germany's urban centers that came to play an increasingly important role in the social, economic, political, religious, and military life of the German kingdom after the turn of the millennium. The translation of the four texts in this volume is intended to help fill these lacunae. They focus on the city of Worms in the period c.1000 to c.1300. From them readers can follow developments in this city over a period of almost three centuries from the perspective of writers who lived there, gaining insights about the lives of both rich and poor, Christian and Jew. No other city in Germany provides a similar opportunity for comparison of changes over time. As important, Worms was an 'early adopter' of new political, economic, institutional, and military traditions, which would later become normative for cities throughout the German kingdom. Worms was one of the first cities to develop as a center of episcopal power; it was also one of the first to develop an independent urban government, and was precocious in emerging as a de facto city-state in the mid-thirteenth century. These political developments, with their concomitant social, economic, and military consequences, would define urban life throughout the German kingdom. In sum, the history of Worms as told in the narrative sources in this volume can be understood as illuminating the broader urban history of the German kingdom at the heigh

Essays throwing fresh light on what it was like to be a medieval soldier, drawing on archival research. The "long" fourteenth century saw England fighting wars on a number of diverse fronts - not just abroad, in the Hundred Years War, but closer to home. But while tactics, battles, and logistics have been frequently discussed, the actual experience of being a soldier has been less often studied. Via a careful re-evaluation of original sources, and the use of innovative methodological techniques such as statistical analysis and the use of relational databases, the essays here bring new insights to bear on soldiers, both as individuals and as groups. Topics addressed include military service and the dynamics of recruitment; the social composition of the armies; the question of whether soldiers saw their role as a "profession"; and the experience of prisoners of war.

Provocative interrogation of how the Ottonian kingdom grew and flourished, focussing on the resources required. The Ottonians were the most powerful monarchs in Europe during the tenth and early eleventh century, exercising hegemony in West Francia, Burgundy, and much of Italy in addition to ruling the German realm. Despite their enormous political and military success, however, the foundations of Ottonian royal power remain highly contested and largely misunderstood, with previous scholarship tending to have considered it as depending upon the ability of the king to shape and harness the power of the nobles. This study challenges the dominant historiographical paradigm, rebutting the notion of putative power-sharing between the king and the nobility, which simply did not exist as a legal class in the Ottonian century. Rather, it argues that the foundations of royal power under the Ottonians comprised not only their own enormous wealth, but also their unique authority and ability, through the royal bannum, the authority inherent in the office of the king, to make use of the economic resources and labour of the broad free population of the realm, as well as from the Church. In so doing, the Ottonians drew upon and further developed the administrative, institutional, and ideological inheritance of their Carolingian predecessors, in the process creating the dominant polity in tenth-century Europe.

"The leading academic vehicle for scholarly publication in the field of medieval warfare." Medieval Warfare The essays in this volume of the Journal continue its proud tradition of presenting cutting-edge research with a wide chronological and geographical range, from eleventh-century Georgia (David IV's use of the methods described in De velitatione bellica) to fifteenth-century England and France (a detailed analysis of the use of the under-appreciated lancegay and similar weapons). Iberia and the Empire are also addressed, with a study of Aragonese leaders in the War of the Two Pedros, a discussion of Prince Ferdinand's battle-seeking strategy prior to the battle of Toro in 1476, and an analysis and transcription of a newly-discovered Habsburg battle plan of the early sixteenth century, drawn up for the war against Venice. The volume also embraces different approaches, from cultural-intellectual history (the afterlife of the medieval Christian Warrior), to experimental archaeology (the mechanics of raising trebuchets), to comparison of "the face of battle" in a medieval illuminated manuscript with its depiction in modern films, to archivally-based administrative history (recruitment among the sub-gentry for Edward I's armies).

The most up-to-date research in the period from the Anglo-Saxons to Angevins. The latest volume of the Haskins Society Journal presents recent research on the Anglo-Saxon, Anglo-Norman, and Angevin worlds broadly conceived, and includes topics ranging from the origins of Welsh law and the evidence for the development of the chivalric tournament in the Norman chroniclers to the use of saints to cement regional power, the reception of Dudo of St Quentin, the regional divides in the Norman Kingdom of Sicily, and more. The volume is particularly noteworthy for several studies that bring together historical and archaeological evidence in new and challenging ways.

Ten papers, on campaigns, biographies, military hardware, fortifications and interpreting medieval records. The second issue of this new undertaking broadens its geographical and practical range, widening its focus to draw in the amateur specialist in addition to military historians: the study of the origins of the crossbow industry inEngland is a case in point. Other papers include studies of campaigns (Henry II in Wales and Henry of Lancaster in France), articles on weaponry and Spanish fortifications in the Mediterranean, a brief life of the mercenary Armengol VI of Urgel, and case studies of the interpretation of chronicles in reconstructing battles and military action. Taken together, the articles reinforce the centrality of fighting and warfare in the middle ages, adding valuabledetail to an understanding of medieval society. Contributors: DAVID S.

A complete survey of the military campaigns of the early Saxons, tactics, strategy, and logistics, demonstrating in particular the sophistication of the administration involved. Over the course of half a century, the first two kings of the Saxon dynasty, Henry I (919-936) and Otto I (936-973), waged war across the length and breadth of Europe. Ottonian armies campaigned from the banks of the Oder in the east to the Seine in the west, and from the shores of the Baltic Sea in the north, to the Adriatic and Mediterranean in the south. In the course of scores of military operations, accompanied by diligent diplomatic efforts, Henry and Otto recreated the empire of Charlemagne, and established themselves as the hegemonic rulers in Western Europe. This book shows how Henry I and Otto I achieved this remarkable feat, and provides a comprehensive analysis ofthe organization, training, morale, tactics, and strategy of Ottonian armies over a long half century. Drawing on a vast array of sources, including exceptionally important information developed through archaeological excavations,it demonstrates that the Ottonian kings commanded very large armies in military operations that focused primarily on the capture of fortifications, including many fortress cities of Roman origin. This long-term military success shows that Henry I and Otto I, building upon the inheritance of their Carolingian predecessors, and ultimately that of the late Roman empire, possessed an extensive and well-organized administration, and indeed, bureaucracy, whichmobilized the resources that were necessary for the successful conduct of war.

The Journal of Medieval Military History continues to consolidate its now assured position as the leading academic vehicle for scholarly publication in the field of medieval warfare. Medieval Warfare This volume has a special focus on the topic of proxy actors and irregular forces in medieval warfare. John France and Jochen G. Schenk offer broad overviews: France addresses the military role of non-noble combatants and the significance of differences between medieval and modern ideas of the "legitimacy" of war-fighters, while Schenk applies a concept originating in political science - Mary Kaldor's idea of "New Wars" - to the conflicts of the Middle Ages, showing that in some ways, what is old is new again. Alex Mallett likewise ties the past to the present, comparing Muslim responses to the Crusades with modern responses to the Western-led invasion of Iraq in 2003. Michael Lower and Mike Carr, meanwhile, examine important groups of foreign fighters employed by North African states and Byzantium. In addition, the volume encompasses a study of Anglo-Norman siege engines (by Michael Fulton), three pieces on war and politics in fourteenth-century Iberia (by Douglas Biggs, Donald Kagay, and L.J. Andrew Villalon), and David Green's magisterial survey of imperial policy and military practice in the Plantagenet dominions in the fourteenth and fifteenth centuries.

Latest volume in the leading forum for debate on aspects of medieval warfare. The tenth anniversary of the Journal includes pieces by some of the most distinguished scholars of military history, including an analysis of tenth-century Ottonian warfare on the eastern frontier of the Empire by David andBernard Bachrach. As ever, the contributions cover a wide span both chronologically (from an analysis of the careers of Justinian's generals in the sixth century, to a study of intelligence-gathering in the Guelders War at the start of the sixteenth) and geographically (from Michael Prestwich's transcription of excerpts from the Hagnaby chronicle describing Edward I's wars in Wales, to a detailed treatment of the Ottoman-Hungarian campaigns of 1442). Other papers address the battle of Rio Salado (1340); the nature of chivalric warfare as presented in the contemporary biography of "le bon duc" Louis de Bourbon (1337-1410); and the military content of the Lay of the Cid.

Essays illuminate a wide range of topics from the Middle Ages, from the seals of an empress to priests' wives and the undead. This volume of the Haskins Society Journal demonstrates the Society's continued engagement with historical and interdisciplinary research from the early to the central Middle Ages on a broad range of topics including militarism, piety, the miraculous and the monstrous. Chapters explore material culture through a mythic eleventh-century papal banner and the seals and coins of the Empress Matilda; offer new insights into Carolingian hagiography and into the undead in the Historia rerum Anglicarum. Further chapters feature new evidence on the role of priests' wives, the tensions of multiple lordships, shifting identities in the Irish Sea world, and the didactic use of royal anger. A fresh examination of Aelred of Rievaulx's Relatio de Standaro and a re-assessment of Flemish documentary practice continue the Haskins Society's commitment to primary source analysis. Two essays on the thirteenth century, including links between Crusade spirituality and lay penitential strategies and an investigation into the economic costs of waging war, round out the volume.

The Journal of Medieval Military History continues to consolidate its now assured position as the leading academic vehicle for scholarly publication in the field of medieval warfare. Medieval Warfare This volume continues to reflect the vibrancy and diversity of the field, through the rich variety of topics and methodologies its chapters treat, and its geographical and chronological range. It includes an analytical narrative of the eastern campaigns of Henry II (1003-1017), demonstrating the strength and sophistication of German military institutions in this early period; a social-history approach to the First Crusade, looking at how European trends towards increasing political participation by the common people played out in the crusading army; an argument for radical change in Scandinavian naval warfare in the thirteenth century, including tactical innovations and the use of new types of large warships; and a toponymonographical approach to the continued presence of Pecheneg soldiers employing steppe tactics in Hungary in the thirteenth century. There are also essays on the sources used by English and French chroniclers to describe battles; the use of practical experimentation to determine the importance of different types of soft armor in helping mail to resist arrows; the role and importance of cavalry in the siege-based warfare of the later Hundred Years War; and the siege of Pisa in 1499, drawing on archival records to illustrate the logistical challenges facing the besiegers. The volume also includes freshly re-examined and re-edited manuscript texts of late-medieval gunpowder recipes.

The first comprehensive analysis of the dynamic interpenetration of religion and war in the West from C4 to early C13. Warfare in all histories and cultures shows evidence of the driving need to sanctify the cause, from the personal devotions of individuals to the grand designs of the architects of battle. In his important study David Bachrach takes a first thorough look at warfare in western Europe and its interaction with Christianity, from the initial appearance of the pacifist sect to the medieval popes' certainty of the crusades as "holy war". Religion played a necessary and crucial role in the conduct of war during late Antiquity and the middle ages. Military discipline and morale depended in significant part on religious rites carried out by priests and soldiers in the field and by their supporters on the home front. Just as importantly, warfare in the late Roman empire and its western successor states had a profound impact on Christian religious practice and doctrine: liturgical developments - in prayer, communion, confession, penance - can be linked to the military needs of the Christian Roman world and the Christian states of medieval Europe. Even more profound was the transformation of Christianity itself from pacifism to a faith which justified and eventually glorified killing on behalf of the Church. This volume provides the first comprehensive analysis of the dynamic interpenetration of religion and war in the West during almost a thousand years, fromthe accession of Constantine the Great in the early fourth century until the eve of the Fourth Lateran Council in the early thirteenth. With its often new interpretations of a vast array of sources, Religion and the Conduct ofWar has much to say to historians and others on the nature of war and its relationship with faith. DAVID S. BACHRACH is Associate Professor of History, University of New Hampshire.

Wide-ranging and current research into the Anglo-Norman and Angevin worlds. This volume of the Haskins Society Journal brings together a rich and interdisciplinary collection of articles. Topics range from the politics and military organization of northern worlds of the Anglo-Normans and Angevins in the twelfth and thirteenth centuries, to the economic activity of women in Catalonia and political unrest in thirteenth-century Tripoli. Martin Millett's chapter on the significance of rural life in Roman Britain for the early Middle Ages continues the Journal's commitment to archaeological approaches to medieval history, while contributions on AElfric's complex use of sources in his homilies, Byrhtferth of Ramsey's reinterpretation of the Alfredian past, and the little known History of Alfred of Beverly engage with crucial questions of sources and historiographical production within Anglo-Saxon and Anglo-Norman England. Pieces on the political meaning of the EmpressHelena and Constantine I for Angevin political ambitions and the role of relics such as the Holy Lance in strategies of political legitimation in Anglo-Saxon England and Ottonian Germany in the tenth century complete the volume.

This is the first translation into English of Ralph of Caen's Gesta Tancredi. This text provides an exceptionally important narrative of the First Crusade and its immediate aftermath, covering the period 1096-1105, but is often neglected, due in no small part to the difficulties of its Latin. A native of the Norman city of Caen where he was a student of Arnulf, the future patriarch of Jerusalem, in 1107 Ralph joined Bohemond of Taranto's army as a military chaplain. After arriving in the East, Ralph took service with Bohemond's nephew Tancred, who ruled the principality of Antioch from 1108 to 1112. Although dedicated to Arnulf, the Gesta Tancredi focuses on the careers of Bohemond and, especially, of Tancred. It is one of the most important sources - indeed the most important Latin source - for the Norman campaigns in Cilicia (1097-1108), and for the early Norman rule of Antioch. The work as a whole has a striking Norman point of view and contains details found in no other source, providing a corrective to the strong northern focus of most of the other narrative sources for the First Crusade.
