Mont Orgueil was unsuccessfully besieged by the French under the leadership of the Duc de Bourbon and the great Bertrand du Guesclin, Marshal of France (whose splendid tomb may still be seen in the north chapel of St. Laurent, at Le Puy), in 1374. It was in honour of this achievement that it received its present name from Thomas, Duke of Clarence, and brother of Henry V. Looking southward from Mont Orgueil at low tide it is possible to realize the extraordinary difficulties that attend the navigation of the Jersey seas. The coast from this point to St. Aubin is flat, but as far as eye can see the surface of the water is a vast archipelago of broken rocks and reefs. Still farther out to sea is the hardly submerged plateau of the Minquiers, with here and there a point that just lifts above high water. There is a second stretch of low sandy coast on the west of the island, at St. Ouen's Bay, guarded in its turn by a second reef of rocks. Nor do these exhaust the possibilities of coming to ruin on this iron coast. It is not without reason that the steam-packets from England run in the daytime only in summer, when the long light evenings give every opportunity of picking their way through the narrow passages. The fate of the _Stella_ (on the afternoon of Maunday Thursday, 1899), somewhere in the neighbourhood of the terrible Casquets, is still too vivid in men's memories to need re-telling. The exact point of striking is unknown. The _Stella_ settled down in the afternoon mist, and no man has ever traced her, or identified her grave in "the vast and wandering" main.
