There were lights on board the vessels, many of the crews remaining on board. They made their way along until they reached the spot they aimed at. Here lay the three sets of vessels, each six deep; their masts had been removed, and the great towers rose high into the darkness above the platforms extending over their decks. The planks forming the gangways up which the towers had been moved had been taken away, save one which gave access to each tier, and Edmund doubted not that it was intended that they should the next morning move across the river in tow of the numerous row-boats. The two Saxons did not attempt to go on board, as they had now found out all they wanted, and might mar all by disturbing some sleeper upon the platform. They accordingly returned to the spot where the band were awaiting them. "I propose, Egbert," Edmund said, "that as we go along we cut the mooring-ropes of all the vessels. We must do it quietly so as not to excite any alarm, and they will know nothing of it until they find themselves drifting down the river in a mass. Then there will be great jostling and carrying away of bowsprits and bulwarks, and the confusion and shouting which will arise will tend to confuse the Danes and to distract their attention from us." Egbert agreed to the proposal, and as soon as they reached the first ships the Saxons began their work, sawing with their knives and daggers through the ropes. The vessels lay four or five deep and there were many cables to cut, but the keen knives of the Saxons made short work of these. Before beginning their work they had spread along the bank, leaving only two men abreast of each ship, so that in the course of two or three minutes the cables for the length of forty ships were severed, and these and their consorts beyond them began to drift out into the stream. The Saxons ran quickly on ahead and repeated the work until the whole of the vessels below those forming the platform for the towers were adrift in the stream; but by this time those in the ships at the lower end of the tiers had taken the alarm, and shouts of wonder and anger rose on the air. The nine Saxons told off for the purpose leaped into three small boats and rowed out into the stream, while the rest of the band, divided into three parties, dashed across the planks on to the platforms. The Danes here had already been alarmed by the uproar from the vessels adrift, and although unable to see what was passing judged that something was wrong, and had called to their comrades sleeping in the holds to come up.
