Now we came to the crest of the hill where the track goes down to the level of the river and marshes and to the causeway, which we crossed in the early morning. I could see now how narrow the outlet of the river was between the hills where it joined the main tidal waters, and the causeway was low, and both it and the bridge were very ancient. They call it Boreham Bridge, and it is a place that I shall not forget.

When we were halfway down the steep hill suddenly the first blast of the gale smote us in the face, and that with a roar and howl and rush that drowned all other sounds. The branches flew from the trees along the hillside, and more than one great trunk gave way at last to that onset. Then all along the coastline grew and widened a white line of flying spindrift that hid the distant gray walls of Pevensea on its low island, and shone like snow against the black dun-edged cloud that came up from out of the sea.

"Hurry, men," shouted Wulfnoth, "or the bridge will be down! Look at the tide!"

And that was racing up inland, already foaming through the wooden arches that spanned its course. I had heard that the tide reached this place a full hour after it began to flow at Pevensea, and even now it was thus, two hours before it should have been at its highest there.

Wulfnoth's men led, and then came the earl, riding beside Spray and the horse which bore the treasure. Olaf was riding just behind them, and I marched with our crew not ten paces after him. So we went down the hill, and so we stepped on the causeway, and came to the first timbers of the bridge. And hardly had I stepped on them than there came a great shout from the men behind us, while one seized my arm and pointed seaward across the marshes.

There came rushing across the level--blending channel and land into one sea as it passed--a vast white roller, great as any wave which breaks upon the shore, and its length was lost behind the hill before us, and far away to our left. So swiftly did it come that it seemed that none of us might gain the hill before it whelmed us and causeway and bridge alike.

Earl Wulfnoth grasped the bridle of the pack horse, and the man Spray lashed it, shouting aloud to us to hasten. And Olaf turned in his saddle and saw me, and reined up until I grasped his stirrup leather, and ran on beside him. And our men broke and ran, some following us, and some going back to the hill whence we came. And all the while the great white billow was thundering nearer, and my head reeled with its noise and terror till I knew not what I was doing, and let go my hold of Olaf's stirrup.

Then it broke over bridge and causeway, and through its roar I heard yells, and the crash of broken timber, before I lost all knowledge of aught but that I was lost in that mighty wave, and was being whirled like a straw before it, where it would take me.

I struck out wildly as if to swim--but of what avail was that against the weight of rushing water? I seemed to be rolled over and against broken timber and reeds and stones--and once my hand touched a man, for I felt it grate over the scales of armour--and my ears were full of roarings and strange sounds, and I thought that I was surely lost.

Then a strong grip was on me, and the water flew past me, and hurled things at me, for I no longer went with it. My feet touched ground, and other hands held me, and then I was ashore, and spent almost nigh to death. Well for me it was that in the old days by the Stour river I had loved to swim and dive in the deep pool behind the island, for I had learned to save my breath. Had I not done so, the choking of the great wave had surely ended my days.
