Vegetius

One of the most frustrating things about Charles Oman is that he ignores when his medieval sources were alluding to famous ancient texts. At the battle of Benevento in 1266, the army of Charles of Anjou crossed the Apennines in February only to find themselves trapped between the mountains and the swollen River Calore with Manfred of Sicily and his army on the other side. Charles’ men were already reduced to eating fallen pack animals, and it was hard to see how they could go forward or back. But then fortune intervened:

Ricordano Malaspina wonders why Manfred crossed the River Calore at all since if he had waited a day or two, King Charles and his people would have been killed without a blow of a sword through lack of vittles (columns 1002, 1003). Oman wonders whether Manfred was worried about treachery or desertion, and asks whether “perhaps in the spirit of the mediaeval knight, he preferred to beat his adversary by the sword rather than hunger.” But any attentive reader in the 13th century would have seen that beating the enemy with hunger rather than the sword is a strategic principle from the third book of Vegetius on military matters. He mentions it three times: 3.3.1, 3.9.8., 3.26.32. It seems to me that Malaspina was just as unimpressed with Manfred’s strategic decisions as Oman was.
