In time this union contributed materially to the expansive energy of the British Empire, but it did not substantially help Marlborough to win his brilliant victories in the war with France (1702-1713). Apart from the general defeat of Louis XIV's ambition to dominate Europe, the most important result, from the British point of view, was the definite establishment of Great Britain as a Mediterranean power by the acquisition of Gibraltar and Minorca. English expeditions against Canada had not been very successful, but the Peace of Utrecht (1713) finally secured for the empire the outworks of the Canadian citadel-- Hudson's Bay Territories, Newfoundland, and the future provinces of Nova Scotia and New Brunswick. The trading privileges which Great Britain also secured in Spanish America both assisted the vast growth of British commerce under Walpole's pacific rule, and provoked the war with Spain in 1739 which helped to bring about his fall. This war, which soon merged in the war of the Austrian Succession (1741-1748), was indecisive in its colonial aspects, and left the question of French or English predominance in India and North America to be settled in the Seven Years' War of 1756-1763. War, however, decides little by itself, and three of the world's greatest soldiers, Alexander, Hannibal, and Napoleon, founded no permanent empires. An excellent servant, but a bad master, the soldier needs to be the instrument of other than military forces if his labours are to last; and the permanence of the results of the Seven Years' War is due less to the genius of Pitt, Wolfe, Clive, and Howe than to the causes which laid the foundations of their achievements. The future of North America was determined not so much by Wolfe's capture of Quebec-- which had fallen into British hands before--as by the fact that before the Seven Years' War broke out there were a million and a quarter British colonists against some eighty thousand French. If Canada had not fallen in the Seven Years' War, it would have succumbed to British arms in the wars of the French Revolution and Napoleon. The fate of India seemed less certain, and the genius of Dupleix roused better hopes for France; yet India, defenceless as it was against European forces, was bound to fall a prize to the masters of the sea, unless some European state could control its almost impassable overland approaches. Clive, perhaps, was almost as much the brilliant adventurer as Dupleix, but he was supported at need by an organized government more susceptible than the French _ancien régime_ to the pressure of commercial interests and of popular ambitions.
