Then when the sky was covered by the shades of night, they launched their boats and embarked in them and stationed themselves at the arm of the sea which ran on the land side, though in front of the said land there is another island called Cerina.[N161] And so they landed on Tider, but did not find anyone, wherefore they turned back and retired to their boats and went forward so far that it was already sun rise. And Lançarote issued forth from the side of Cerina and went along by land, ordering the boats to make their way by water; and when they saw that they found nothing, Lançarote said to the others that it would be well to go forward to a certain promontory, and all agreed with him. And while seeking to prepare themselves and to gather themselves together for starting, Lançarote heard an ass bray. "Meseemeth," said he to the others, "I hear the bray of an ass, as though some pleasure were in store for us; for perchance it is God's will that we should not depart hence without booty." And because there was no doubt of what he had heard, he told them to await him there, and that he would go upon some sandhills to see what that could be. And while the others were waiting, he mounted up the sandhills, and from there looking round on all sides he saw the Moors where they stood, many more in number than our men. And these Moors were getting ready their asses and gathering up their baggage, as men who sought to leave that place, with little care of what in a few hours would overtake them. Truth it is that they were endeavouring to set out, but they deemed not it was upon so long a journey. But Lançarote, as soon as he had seen them, descended very quietly from the place where he was, and came and gave the news to the others, and you know well how glad they would be when they heard it. "Now, God be praised," said he, "we have what we sought. The Moors are here, just ready to move away. They are more in number than we: if you will only labour the victory is ours. Strengthen your hearts and make your feet swift, for on the first encounter will depend the whole of our victory."
