Since the end of the fifteenth century, has been available primarily through Antoine Vérard's imprint of 1488 or William Caxton's 1489 translation, . Vérard even suggested that the work was his own translation of the Roman writer Vegetius, making no mention of Christine 's name. Caxton attributed the work to Christine, but it is impossible to identify the manuscript he used for his translation. Moreoever, both translations are inaccurate. The Willards correct these inaccuracies in a clear and easy-to-read translation, which they supplement with notes and an introduction that will greatly benefit students, scholars, and enthusiasts alike. Publication of this work should change our perception both of medieval warfare and of Christine de Pizan.
