The voyage soon became eventful. Nearly three hundred tons of coal was a heavy concentrated cargo for the tremendous storm she encountered on the Grand Banks of Newfoundland. {143} She strained; her starboard engine was disabled; she began to leak; and the engineer came up to tell M'Dougall she was sinking. But M'Dougall held his course, started the pumps, and kept her under way for a week with only the port engine going. The whole passage from Pictou, counting the time she was detained at Cowes repairing boilers, took twenty-five days. M'Dougall, a sturdy Scotsman, native of Oban, must have been sorely tempted to 'put the kettle off the boil' and run her under sail. But either the port or starboard engine, or both, worked her the whole way over, and thus for ever established her claim to priority in transatlantic navigation under steam alone. In London she was sold for L10,000, just twice what she had fetched at sheriff's sale in Quebec some months before. She was at once chartered, crew and all, by the Portuguese government, who declined to buy her for conversion into a man-of-war. In 1834, however, she did become a man-of-war, this time under the Spanish flag, though flying the broad Pennant of Commodore Henry, who was then commanding the British Auxiliary Steam Squadron against the Carlists in the north of Spain. Two years later, on May 5, 1836, under {144} her Spanish name of _Isabella Segunda_, she made another record. When the British Legion, under Sir de Lacy Evans, was attacking the Carlists in the bay of St Sebastian, she stood in towards the Carlist flank and thereupon fired the first shot that any steam man-of-war had ever fired in action. Strangely enough, she cannot be said to have come to any definite end as an individual ship. She continued in the Spanish service till 1840, when she was sent to Bordeaux for repairs. The Spaniards, who are notorious slovens at keeping things shipshape, had allowed her to run down to bare rot after her Britisher-Canadian crew had left her. So the French bought her for a hulk and left her where she was. But the Spaniards took her engines out and put them into a new _Isabella Segunda_, which was wrecked in a storm on the Algerian coast in 1860. Her career of record-making is well worth a general summary: the _Royal William_ was the first steamer built to foster inter-colonial trade in Canada; the first Canadian steamer specially designed for work at sea; the first sea-going steamer to enter a port in the United States under the British flag; the first steam transport in Portugal; the first steam man-of-war in {145} Spain; the first naval steamer that ever fired a shot in action; and the first vessel in the world that ever crossed an ocean under steam alone.
