Were it not for that constant thirst for glory that from time immemorial gives not a moment's peace to kings, presidents and military leaders, this conquest of Lisbon from the Moors could have been achieved with all the tranquillity in this world, after all, only a fool steps into the lion's cage to engage in combat instead of depriving it of food and sitting down to watch it die from starvation. It is true that with the passing of the centuries we learn something, and nowadays it is fairly common practice to use the privation of food and other necessities and such other reasons as a means of persuading those who out of stubbornness or a lack of understanding have refused to capitulate. However, these five hundred thousand are different just as their history would be different. What is important here is to observe the concurrence of two quite distinct episodes, such as the destruction and burning down of the tower at Porta de Ferro and the first signs of famine in the city, which, united and compared in the minds of the king's chiefs of staff, made it clear that while they should continue with the struggle, in the strict meaning of the word, for the honour of the Portuguese army, good strategy would dictate intensifying the siege, because in due course not only would the Moors have devoured everything down to the last crumb and rat, but they would end up devouring each other. If the French and the Normans were to carry on building their towers, if the Lusitanians for their part were to apply the lessons learned from knight Heinrich in order to erect their own war machine, if the artillery were to keep up regular bombardments, and the archers were to throw darts, arrows, spears and javelins, thus putting to good use the daily output of weapons workshops of Braço de Prata, these would be nothing more than symbolic gestures to inscribe in the epics, when compared with the last and conclusive solution, famine. And so the various captains gave strict orders to their armies that they should guard the outer walls day and night, not just the gates, but above all any secluded corners, certain hidden angles that might afford protection, and also any stretches facing the sea, not because any supplies could be brought into the city by that route, for there could never be enough of them to meet their needs, but to prevent any messengers from getting through the blockade and carrying pleas for help to the villages in the Alentejo, both for provisions and volunteers to attack the assailants along the coast, the one being as welcome as the other. Their caution soon proved to be well-founded, when at dead of night with no moonlight a tiny canoe was discovered trying to sneak out between the galleys of the fleet and when the oarsman was brought before the admiral, he confessed to carrying letters addressed to the mayors of Almada and Palmela, from which it became clear how desperately the wretched inhabitants of Lisbon were in need of food. Despite the vigilance, the odd messenger must have crossed the lines, for weeks later, floating at the bottom of the wall that looked on to the river, the corpse of a Moor was picked up and when hoisted up on to the nearest watch-tower was found to be carrying a letter from the King of Evora, that fortunately never reached its destination, so cruel, inhuman and hypocritical was its message, considering that these were brothers of the same race and religion, and this was what the letter said, the King of E/ora wishes the inhabitants of Lisbon their freedom, for some time now I have held a truce with the King of the Portuguese, and I cannot go back on my word and trouble him and his subjects with war, ransom your lives with your money, so that what should be used for your salvation is not used for your downfall, farewell. This man was king, and in order not to break the truce he had drawn up with our Afonso Henriques, forgetting that this same Afonso had broken it to storm and capture Santarém, he allowed the doomed populace of Lisbon to die an ignominious death, while the courier who had left Lisbon with a plea for help did not take advantage of the opportunity to escape to safe territory, but returned with the evil tidings, only to die before delivering the message announcing abandonment and betrayal. How true that men are not always in their right place, this Moor would have rushed to Lisbon had he been the King of Evora, but the King of Evora would obviously have fled right on the first mission, were it not for the fact that they brought him under escort as far as Cacilhas with the reply and told him, Go throw yourself into the sea and make no attempt to come back.
