Beyond Damme the canal winds on through the same flat landscape, low-lying, water-logged, with small farmhouses and scanty trees, and in the distance, on the few patches of higher ground, the churches of Oostkerke and Westcapelle. At last, soon after passing the Dutch frontier, the canal ends in a little dock with gray, lichen-covered sides; and this is Sluis, a dull place, with a few narrow streets, a market-place, two churches, and a belfry of the fourteenth century. It is quite inland now, miles from the salt water; and from the high ramparts which still surround it the view extends to the north across broad green fields, covering what was once the bed of the sea, in the days when the tide ebbed and flowed in the channel of the Zwijn, over which ships passed sailing on their way to Bruges. But any English traveller who, having gone a little way out of the beaten track of summer tourists, may chance to mount the ramparts, and look down upon the fields which stretch away to the shores of the North Sea and the estuary of the Scheldt, and inland beyond Damme to the Belfry and the spires of Bruges, is gazing on the scene of a great event in the naval history of England. Here, on what is now dry land, on the morning of June 24, 1340, 800 ships of war, full of armed men--35,000 of them--were drawn up in line of battle; and further out to sea, beyond the entrance of the Zwijn, the newly-risen sun was shining on the sails of another fleet which was manoeuvring in the offing.
