The seventeenth century saw the gradual displacement of galleys in favour of sailing ships. The long voyages across the Atlantic and to the East had given great impetus to the development of the sailing vessel; its increasing use, and the entrance of England and Holland into the Mediterranean, had shown the Powers of that sea its superiority over the galley; finally, slaves were becoming more difficult to obtain in sufficient quantities, while criminals had never been a satisfactory source of supply. The Knights were slow in changing the oar for the sail, and to the end kept a small squadron of galleys as well as men-of-war. When Napoleon captured the island, in 1798, he found there two men-of-war, one frigate, and four galleys. The pride and the renown of the Order had always demanded a salute from the warships of other nations, and even the mighty Louis XIV. yielded this privilege to the little squadron. There is extant an interesting correspondence between Charles II. and the Grand Master, Nicholas Cottoner, on the subject of salutes. A squadron of the British Fleet, under Admiral Sir John Narborough, had refused to salute Valetta unless assured of a response from the guns of the fortress--a mark of respect that the Order was unwilling to pay to the British flag. The Grand Master had also ventured to doubt Narborough's rank as Admiral, but the affair was amicably settled to the satisfaction of all. Though the decline of the Order was obvious to Europe throughout the eighteenth century, and the value of such a fortress as Malta to a Mediterranean Power apparent to all, yet there is little definite proof of any desire to wrest the island from the Knights. Of all the nations round the Mediterranean, France alone could be said not to be in a state of decay; Venice, Genoa, and Turkey were becoming more and more feeble at sea, and there was little fear of an attack on Malta from any of them; and though Spain paid great attention to her fleet in the second part of the eighteenth century, there was little reason to fear her aggression. Britain was acquiring greater and greater interests in the Mediterranean, but most of her attentions were directed to Spain and France. While the Knights kept their neutrality, however decadent and feeble they might be, there was little fear of their being disturbed. Europe still respected the relics of a glorious past of six centuries of unceasing warfare against the Moslem; but the moment that past with its survivals became itself anathema the Knights and their organisation would collapse at once. The French Revolution meant death to the Knights of the Order of St. John as well as to other bodies of aristocrats. CHAPTER V THE FALL 1789-1798.
