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 and Bernard 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'.
