Churchill had not been long in Flanders, before his talents and gallantry won for him deserved distinction. The campaign of 1672, which brought the French armies to the gates of Amsterdam, and placed the United States within a hair's-breadth of destruction, was to him fruitful in valuable lessons. He distinguished himself afterwards so much at the siege of Nimeguen, that Turenne, who constantly called him by his _sobriquet_ of "the handsome Englishman," predicted that he would one day be a great man. In the following year he had the good fortune to save the life of his colonel, the Duke of Monmouth; and distinguished himself so much at the siege of Maestricht, that Louis XIV. publicly thanked him at the head of his army, and promised him his powerful influence with Charles II. for future promotion. He little thought what a formidable enemy he was then fostering at the court of his obsequious brother sovereign. The result of Louis XIV.'s intercession was, that Churchill was made lieutenant-colonel; and he continued to serve with the English auxiliary force in Flanders, under the French generals, till 1677, when he returned with his regiment to London. Beyond all doubt it was these five years' service under the great masters of the military art, who then sustained the power and cast a halo round the crown of Louis XIV., which rendered Marlborough the consummate commander that, from the moment he was placed at the head of the Allied armies, he showed himself to have become. One of the most interesting and instructive lessons to be learned from biography is the long steps, the vast amount of previous preparation, the numerous changes, some prosperous, others adverse, by which the mind of a great man is formed, and he is prepared for playing the important part he is intended to perform on the theatre of the world. Providence does nothing in vain, and when it has selected a particular mind for great achievement, the events which happen to it all seem to conspire in a mysterious way for its development. Were any one omitted, some essential quality in the character of the future hero, statesman, or philosopher would be found to be awanting.
