Military training and strategy are two important matters on which the sources are typically silent. There are no references in literature or laws to men training, and so it is necessary to fall back on inference. For the noble warrior, his childhood was of first importance in learning both individual military skills and the teamwork essential for success in battle. Perhaps the games the youthful Cuthbert played ('wrestling, jumping, running, and every other exercise') had some military significance. Turning to strategy, of the period before Alfred the evidence gives the impression that Anglo-Saxon armies fought battles frequently. Battle was risky and best avoided unless all the factors were on your side. But if you were in a position so advantageous that you were willing to take the chance, it is likely that your enemy would be in such a weak position that he would avoid battle and pay tribute. Battles put the princes' lives at risk, as is demonstrated by the Northumbrian and Mercian overlordships brought to an end by a defeat in the field. Gillingham has shown how few pitched battles Charlemagne and Richard I chose to fight.
