There is another point besides the fettering of prisoners in which attention is drawn in Froissart to the exceptional barbarity of the Spaniards; and in no estimate of the military type of life in the palmiest days of chivalry would it be reasonable to omit all consideration of Spain. In the war between Castile and Portugal, the forces under Don John of Castile laid siege to Lisbon, closely investing it; and if any Portuguese were taken prisoners in a skirmish or otherwise, their eyes were put out, their legs, arms, or other members torn off, and in such plight they were sent back to Lisbon with the message that when the town was taken mercy would be shown to none. Such was the story told by the Portuguese ambassador to the Duke of Lancaster, and repeated on his authority by Froissart. For the credit of humanity, to say nothing of chivalry, one would fain disbelieve the tale altogether, or regard it as an episode that stood by itself and apart from the general practice of the age, since it is the only one of the kind related by Froissart. But the frequency as much as the rarity of a practice may account for the silence of an annalist, and there is little doubt that mutilation of the kind described was common in the chivalrous period, even if obsolete or nearly so in the fourteenth century. Blinding and castration were not only punishments inflicted for offences against the forest laws of the Norman kings of England, but were the common fate of captive enemies in arms throughout Europe in the eleventh and twelfth centuries. This, for instance, was the treatment of their Welsh prisoners by the Earls of Shrewsbury and Chester in 1098; as also of William III., King of Sicily, at the hands of Henry, Emperor of the Romans, in 1194. At the close of the twelfth century, in the war between Richard I. of England and Philip Augustus of France, blinding was resorted to on both sides; for Hoveden expressly says: ‘The King of France had the eyes put out of many of the English king’s subjects whom he had made prisoners, and this provoked the King of England, unwilling as he was, to similar acts of impiety.’ And to take a last instance, in 1225, the Milanese having taken prisoners 500 Genoese crossbowmen, deprived each of them of an eye and an arm, in revenge for the injury done by their bows.[44] So that it would be interesting, if possible, to learn from some historian the date and cause of the cessation of customs so profoundly barbarous and brutal.
