After that he bade us all sleep, for we had some long hours to wait for the falling tide when all was done. And we did so, after a good meal, as well as we could, while the wains yet brought stones, and arrows and darts in sheaves to the bridge. But forward in our ships the men were coiling the great cables that should, we hoped, bring the bridge and stones alike down harmlessly to us. It was plain that the Danes knew what the roofs over the ships were for, since all the while that we wrought we could see them pointing and laughing one to another in scorn, from where we lay, not much beyond arrow shot below them. But not one of all the men on the bridge could have guessed what our real plan might be. Only we who looked at the ancient bridge from the water, and marked how frail and decaying some of the piles that upheld its narrow spans were, knew how likely it was that Olaf's plan would succeed. The wide roadway seemed to them to be strong enough for the wooden towers and the many tons of stones they had burdened it with; but now that Olaf had showed us, we saw that it was none so safe, so we waited in good spirits. The tide reached its height and as the ships swung idly to their cables on the slack, the Danes thronged the bridge, thinking, doubtless, that we should attack when they were within reach, as yesterday. The hum of their voices came down to us, and as the time went by, and the ebb tide set in, the hum strengthened into a long roar of voices, that broke out into a yelling laugh now and then, as some word of scorn went round. For they thought our Norsemen were afraid. But they could not see beneath the penthouse roofs, where the men, three at each oar, were armed and ready. Nor could they see the gangs of twelve men told off to the cables on each foredeck. Six of these were to pass the cables round the piles and make fast while the other six were to stand by with shields ready, in case the roofs were broken. But even then it should not take long to do all we needed, and some of the roof would be left surely at the worst. Four only of the ships were to touch the bridge, one at each of the four midmost pilings. The other four were made fast, stern to stern of the leading ships, so that their weight of oar play might be used to the full in the long pull to come, and two ships would haul at each set of piles where the weight was heaviest upon the bridge. So we waited until the tide was at its fiercest ebb. The water rushed through the narrow waterways of the bridge in a broken torrent streaked with foam that swirled far down the stream towards us; so the time having come, Olaf gave the word. His own ship was one of the two in the middle, and Rani was in command of the other.
