From early youth, young Churchill was distinguished by the elegance of his manners and the beauty of his countenance and figure – advantages which, coupled with the known loyal principles of his father, and the sufferings he had undergone in the royal cause, procured for him, at the early age of fifteen, the situation of page in the household of the Duke of York, afterwards James II. His inclination for arms was then so decided, that that prince procured for him a commission in one of the regiments of guards when he was only sixteen years old. His uncommonly handsome figure then attracted no small share of notice from the beauties of the court of Charles II., and even awakened a passion in one of the royal mistresses herself. Impatient to signalize himself, however, he left their seductions, and embarked as a volunteer in the expedition against Tangiers in 1766. Thus his first essay in arms was made in actions against the Moors. Having returned to Great Britain, he attracted the notice of the Countess of Castlemaine, afterwards Duchess of Cleveland, then the favorite mistress of Charles II., who had distinguished him by her regard before he embarked for Africa, and who made him a present of £5000, with which the young soldier bought an annuity of £500 a-year, which laid the foundation, says Chesterfield, of all his subsequent fortunes. Charles, to remove a dangerous rival in her unsteady affections, gave him a company in the guards, and sent him to the Continent with the auxiliary force which, in those days of English humiliation, the cabinet of St James's furnished to Louis XIV. to aid him in subduing the United Provinces. Thus, by a singular coincidence, it was under Turenne, Condé, and Vauban that the future conqueror of the Bourbons first learned the art of scientific warfare. Wellington went through the same discipline, but in the inverse order: his first campaigns were made against the French in Flanders, his next against the bastions of Tippoo and the Mahratta horse in Hindostan.
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.
Here also, as in every other period of history, we may see how unprincipled ambition overvaults itself, and the measures which seem at first sight most securely to establish its oppressive reign, are the unseen means by which an overruling power works out its destruction. Doubtless the other ministers of Louis XIV. deemed their master's power secure when this English alliance was concluded; when the English monarch had become a state pensioner of the court of Versailles; when a secret treaty had united them by apparently indissoluble bonds; when the ministers equally and the patriots of England were corrupted by his bribes; when the dreaded fleets of Britain were to be seen in union with those of France, to break down the squadrons of an inconsiderable republic; when the descendants of the conquerors of Cressy, Poitiers, and Azincour stood side by side with the successors of the vanquished in those disastrous fields, to achieve the conquest of Flanders and Holland. Without doubt, so far as human foresight could go, Louvois and Colbert were right. Nothing could appear so decidedly calculated to fix the power of Louis XIV. on an immovable foundation. But how vain are the calculations of the greatest human intellects, when put in opposition to the overruling will of Omnipotence! It was that very English alliance which ruined Louis XIV., as the Austrian alliance and marriage, which seemed to put the keystone in the arch of his greatness, afterwards ruined Napoleon. By the effect, and one of the most desired effects, of the English alliance, a strong body of British auxiliaries were sent to Flanders; the English officers learned the theory and practice of war in the best of all schools, and under the best of all teachers; that ignorance of the military art, the result in every age of our insular situation, and which generally causes the four or five first years of every war to terminate in disaster, was for the time removed, and that mighty genius was developed under the eye of Louis XIV., and by the example of Turenne, which was destined to hurl back to their own frontiers the tide of Gallic invasion, and close in mourning the reign of the Grande Monarque. "Les hommes agissent," says Bossuet, "mais Dieu les mène."
Upon Churchill's return to London, the brilliant reputation which had preceded, and the even augmented personal advantages which accompanied him, immediately rendered him the idol of beauty and fashion. The ladies of the palace vied for his homage – the nobles of the land hastened to cultivate his society. Like Julius Cæsar, he was carried away by the stream, and plunged into the vortex of courtly dissipation with the ardour which marks an energetic character in the pursuit whether of good or evil. The elegance of his person and manners, and charms of his conversation, prevailed so far with Charles II. and the Duke of York, that soon after, though not yet thirty years of age, he obtained a regiment. In 1680 he married the celebrated Sarah Jennings, the favourite lady in attendance on the Princess Anne, second daughter of the Duke of York, one of the most admired beauties of the court, and this alliance increased his influence, already great, with that Prince, and laid the foundation of the future grandeur of his fortunes. Shortly after his marriage he accompanied the Duke of York to Scotland, in the course of which they both were nearly shipwrecked on the coast of Fife. On this occasion the Duke made the greatest efforts to preserve his favourite's life, and succeeded in doing so, although the danger was such that many of the Scottish nobles perished under his eye. On his return to London in 1682, he was presented by his patron to the King, who made him colonel of the third regiment of guards. When the Duke of York ascended the throne in 1685, on the demise of his brother, Churchill kept his place as one of the gentlemen of the bedchamber, and was raised to the rank of brigadier-general. He was sent by his sovereign to Paris to notify his accession to Louis XIV., and on his return he was created a peer by the title of Baron Churchill of Sandbridge in the county of Hertford – a title which he took from an estate there which he had acquired in right of his wife. On the revolt of the Duke of Monmouth, he had an opportunity of showing at once his military ability, and, by a signal service, his gratitude to his benefactor. Lord Feversham had the command of the royal forces, and Churchill was his major-general. The general-in-chief, however, kept so bad a look-out, that he was on the point of being surprised and cut to pieces by the rebel forces, who, on this occasion at least, were conducted with ability. The general and almost all his officers were in their beds, and sound asleep, when Monmouth, at the head of all his forces, silently debouched out of his camp, and suddenly fell on the royal army. The rout would have been complete, and probably James II. dethroned, had not Churchill, whose vigilant eye nothing escaped, observed the movement, and hastily collected a handful of men, with whom he made so vigorous a resistance as gave
