The Portugueze gained several advantages at different times over the Spaniards, and thus prevented them from approaching the frontiers. The king of Portugal might even have penetrated into Castille, had his generals been more able, or his body of regular troops more considerable. The greater part of his army being composed of militia, was much fitter to make incursions than to keep the field: he was frequently destitute even of means to pay his troops, and having abolished most of the taxes on his first accession to the crown, in order to gain the favour of his people; it would have been a dangerous experiment to have re-established them under so new a government. With all these disadvantages, however, he contrived to support the war against Spain, very nearly seventeen years. That country could not boast of greater generals than Portugal; each nation gained more by the weakness of its opponent, than by its own strength; and the exhausted treasury of Philip the IVth, at the latter end of his reign, supplied the place of riches to the new king of Portugal. This prince departed this life on the 6th of November, 1656; and the Portugueze, unable to call forth the attention of posterity to the most striking qualities of their king, confine their praises to his moderation and piety; whilst impartial historians accuse him of want of courage, diffidence of himself, mistrust of others, reserve towards the nobles, who found it difficult to approach his person, whilst he conversed openly and familiarly with his ancient domestics alone, and more especially with the friend and companion of his confessor. The only inference to be drawn from this conduct is, that this prince, naturally peaceable, and given up to his devotions, might be said to possess the good qualities of a private individual, though never the splendid virtues of a great king. His accession to the crown of Portugal must then be solely attributed to the hatred borne by the people of that country to the Spaniards, and to the adroit management of his queen, who made use of this national animosity to raise her to the regal dignity.[24] The king, her husband, in his last will, appointed her regent of the kingdom, rightly judging, that the same conduct and courage which had placed the crown on her head, would not fail to preserve it during the minority of his children. He left behind him two sons and one daughter; the eldest of which, don Alphonso, was nearly thirteen years of age when he succeeded his father. This young prince was of a melancholy disposition, and was deprived of the use of one side: his brother, the infant, don Pedro, was only eight years old; and the infanta, donna Catharine, who was the eldest of the family, was born before the revolution. Don Alphonso being shewn to the people, was proclaimed king, according to the usual forms, and the queen took upon herself, the same day, the regency of the state.
