Edmund and the Saxons had viewed with consternation the approach of the sea-fog. The instant it enveloped the ship the oars were got out and they rowed in the direction of the Danish vessels, which they hoped would drop anchor when the fog reached them. Not a word was spoken on board the Dragon. Edmund, Egbert, and Siegbert stood on the forecastle intently listening for any sound which would betray the position of the Danes, but not a sound was to be heard. They had, they calculated, already reached the spot where the Dane should have been anchored when from the left, but far away astern, a loud call in a woman's voice was heard.

"That must be Freda!" Edmund exclaimed. "Turn the ship; they have passed us in the fog."

The Dragon's head was turned and she was rowed rapidly in the direction of the voice. No further sound was heard. Presently there was a sudden shock which threw everyone on to the deck. The Dragon had run high on the low muddy bank of the river. The tide was falling; and although for a few minutes the crew tried desperately to push her off they soon found that their efforts were in vain, and it was not until the tide again rose high nine hours later that the Dragon floated. Until morning broke nothing could be done, and even when it did so matters were not mended, for the fog was still dense.
