Thus he was a captain at the age of eighteen! The war was now at an end; his ship was paid off, and he went to reside at Caen, for the purpose of acquiring a knowledge of the French language. There he spent a well-employed and agreeable time. Many of the French families of condition resided in the neighbourhood; and the young captain, having brought letters to the Duc de Harcourt, governor of the province, was hospitably received. The French were then a polished people; they knew nothing of republicanism, and were not proud of their ferocity; they had none of that frantic hatred of England which is the folly and the fashion of our day, and might be regarded as a civilised people. The duke invited him to his country-seat, and there showed him the improvements in his grounds, and introduced him to his visitors. Like most men destined to distinction, Sir Sidney Smith was constantly preparing himself for useful service, by the acquisition of knowledge. The Mediterranean is naturally presumed to be the great theatre of naval exploits. He obtained leave of absence, and went to the Mediterranean. While at Gibraltar, thinking, from the violent language of the Emperor of Morocco, that there might be a Moorish war, he made a journey along the coast of Morocco, for the purpose of acquainting himself with the condition of its naval force and harbours. Having obtained the necessary information, which obviously required considerable exertion and no slight expense, he stated its results in a manly and intelligent letter to the Admiralty, offering his services in case of hostilities, and suggesting the appointment of a squadron to be stationed outside the Straits, for the prevention of any naval enterprise on the part of the Moors. Among the most accessible ports, he mentions Mogadore, which, as not being a bar harbour, is easily approachable by ships of force; and though the works contained many guns, yet they were so ill-placed, that in all probability they could not resist an attack. We recollect that the cannonade of this town was one of the exploits on which the Prince de Joinville plumed his heroism, and of which all France talked as if it were the capture of a second Gibraltar. The same spirit of inquiry and preparation for probable service led him to Sweden, during the war of the brave and unfortunate Gustavus with the Empress Catherine. We may pause a moment on the memory of one of the most remarkable princes of his time. Gustavus, born in 1746, in 1771 ascended the throne of Sweden, on the death of his father Frederic.
