During the day that Norris was awaiting the arrival of Dom Antonio's troops the English had not left their trenches, and the defenders feared that some deep design lay behind this. Were they mining, or was Drake sending up some heavy {65} guns? they thought. So when the dawn of the 27th of May showed that the main body of the English was already on its way to Cascaes, Count de Fuentes still doubted whether it was not all a feint to draw him out from the shelter of his walls, and peremptorily refused permission to Count Villa Dorta to follow them up and engage them. The way of the retreating force lay along the shore, but to avoid the fire of the galleys which followed their movements they chose the rough by-paths where possible. And so, all undisciplined, sick, and starving, they wandered and struggled on as best they could, four hundred at least of stragglers and sick being killed or captured by Villa Dorta, who hung upon the rear, notwithstanding his chief's prohibition. Later in the day Fuentes so far conquered his suspicion as to lead his army out to Viera, half-way to Cascaes, but he had barely sighted the enemy than some rumour or suspicion reached him of an intended rising in Lisbon during his absence, and he hurried back again to the city. My Portuguese diarist ridicules the suggestion of such a danger as unworthy of any sensible man; but the utter futility of the English and Portuguese proceedings from the first was such as well might excuse Fuentes for thinking that some deeper design must surely lay behind. The suspicion of the Portuguese on the part of the Spaniards at this time is illustrated by an anecdote given by the Portuguese diarist. Alvaro Souza, the captain of Philip's Portuguese guard, with five companions, accompanied Sancho Bravo, who took out a force to harry the English on their way to Cascaes. Souza straggled and was captured by Spanish soldiers, {66} who did not know him. They were near the castle of São Gian at the mouth of Lisbon harbour and knowing that Pero Venegas, the commandant, was a friend of his father, Souza sent a messenger to him begging him to answer for his loyalty. Venegas declined to reply, and Souza was lead off under arrest. On the way he met the famous Alvaro de Bazan going to his galleys. He was a friend, and Souza appealed to him to stand by him and his companions, "but he answered coldly that he knew him not, nor was this a time to recognise any one." He had, he said, recently answered for some Portuguese fidalgos in the palace, and a few hours afterwards they were arrested for treason.
