Volume 10 of the Journal of Medieval Military History contains only eight studies spread between the sixth to the early sixteenth century. None are weak or unconvincing. Some are quite superb. Depending on tastes, readers will clearly have personal preferences. I will neither present nor comment on each of them, since this is not exactly the point of a book review. I will however mention why I particularly liked this collection through three examples.The first one, which happens to also be the first study of the Journal, is an article on Justinian’s generals. The author lists some 47 of them through the sources and seeks to identify common features and, in particular, how they became generals, what were their terms of service and how they were treated when they were either victorious or defeated. Some of the author’s findings are rather surprising in that their treatments by the Emperor may appear to be counterintuitive, but the explanations provided by the author for such surprises are quite convincing.My second favourite from this collection is an article analysing War in the Lay of the Cid and whether and to what extent the poem has historical value and reflects the deeds of the famous warlord from Castile. The analysis centres in particular on how the Cid of his little army slowly cut off the city of Valencia from its hinterland, taking the surrounding fortresses one by one, before reducing the city itself. As such, it illustrates some of the main features of medieval warfare in the eleventh and twelfth centuries, and in particular its cautiousness and its avoidance of major battles and costly sieges unless and until the enemy had been sufficiently weakened.The third preferred article (the sixth in the collection) is about the Ottoman-Hungarian campaign of 1442 during which Hunyadi, the Hungarian warlord, crushed two Ottoman armies that came raiding across the Danube. In both cases, the raiders were allowed to disperse and either defeated when dispersed, as in the first case, or defeated on their way home, as they were crossing river. Of particular interest are the author’s careful reconstitution of the routes taken by the Ottoman armies and how and where Hunyadi and his forces managed to trap and catch them.The five other articles cover a wide range of topics. One covers the armies and warfare of the Early Saxon Kings (and Emperors) of the Tenth century and is particularly interesting, even if some of its findings may be more tentative than the authors care to admit. A second study is a study of the battle of Salado in 1340 between the Christian forces of Castile and Portugal and the Moslem Marinids from Morocco allied to the forces of Grenada. Two other articles are studies of documents. One focuses upon the biography of Duke Louis de Bourbon and the deeds of this French warlord and contemporary of Bertrand du Guesclin during the Hundred Years’ War. The other studies a little known and secondary document – a chronicle from a Priory – and analyses the information that it can provide on Edward I wars and how reliable this information may be. The last article is perhaps one of the most original. It is about spies and informers in cities and towns during the Guelders War in Holland between 1506 and 1515.Four strong stars.
