In 1708, the Whigs having a majority in the new house, and always the true partisans of the war, firmly seized the power. The five Lords of the Junta, Somers, Oxford, Wharton, Halifax and Sunderland, found themselves reunited in the same cabinet with the Duke of Marlborough and Lord Cowper. Robert Walpole, who had been a member of the house since 1700, but who had as yet occupied only insignificant positions, replaced St. John as secretary of state. This was the beginning of a rivalry which was to last throughout their lives.

During two years the Whig ministry governed with a power which seconded the victories of the Duke of Marlborough. It was nevertheless constantly threatened by the want of personal liking of the queen, as well as by the intrigues of the court, which secretly undermined the influence of the Duchess of Marlborough. Handsome, imperious and brilliant, as well as arrogant and ambitious, Sarah Jennings had for a long time maintained over Queen Anne an authority which increased as her favors multiplied. That domination which she exercised to the very last over her illustrious husband, was slowly declining with the queen. Marlborough had for some time succeeded in maintaining his power by changing from the Whigs to the Tories, and from the Tories to the Whigs. He was sustained at first by the Whigs, formerly his adversaries; a Tory ministry that was to cause his fall was preparing.

Weary of the violences and inequalities of the temper of her haughty favorite, the queen had found some consolation in the affection of a young and adroit woman, a relative of the Duchess of Marlborough. Abigail Hill was simply a waiting-maid to the queen, who had married her, at the suggestion of her protectress, to a Mr. Masham, a poor gentleman of the chamber. At first she was not even admitted to the royal dressing-room. It was little by little, and through chance indiscretions, that the Duchess of Marlborough recognized that she was being supplanted in the confidence of the queen, who was naturally capricious. Notwithstanding her long fidelity to the duchess, the queen could not endure restraint. Mrs. Masham secretly introduced Harley; the anger of the duchess was to serve the ambition of the former Secretary of State, and the aspirations of the Tories towards power.

An unfortunate trial, begun against an insolent and declamatory clergyman. Dr. Sacherevel, embittered religious passions. The High Church and the fashionable world were ardent and pronounced in favor of the accused. His sermon upon the "False Brethren," had not formally attacked the revolution of 1688, but had extolled the absolutism of the prerogative in sustaining the doctrine of non-resistance. His suspension for three years, by the House of Lords, was equivalent to an acquittal. "This fatal trial makes me sick," said Godolphin; "the life of a galley-slave would be a paradise for me." The Tories triumphed. "The ministers have a curate to roast," ironically said St. John, "and they have made so great a fire that they have roasted themselves."

On the 8th of August, 1710, after many significant changes in the cabinet. Lord Godolphin received by a messenger from the royal stables, a note from the queen, praying him to break the white rod—his insignia of office. The queen appeared before Parliament to dissolve it; the Chancellor, Lord Cowper, endeavored to speak, but Anne silenced him. The power passed from the powerful junta of the Whigs, and Harley was named Chancellor of the Exchequer; Lord Rochester became President of the Council, and St. John Secretary of State.

The Duchess of Marlborough, disgraced without being dismissed, no longer saw the queen. Anne, overwhelmed by reproaches and insults, left the chamber where the duchess insisted upon remaining. Some months later the humility and prayers of the great general were unavailing to maintain the duchess in her position at court; he was obliged to pick up from the floor the golden key—the sign of office of the mistress of the robes—that his wife had flung away in her anger.

"She has conducted herself strangely," avowed the duke, "but there is nothing to be done, and it is necessary to endure many things to obtain peace in the household."

The day of grandeur of the Duke of Marlborough had passed; his administration of the funds of the army was condemned by Parliament. He defended himself ably, with that bold moderation which habitually characterized him. He was accused of having taken moneys from the contractors of supplies: he replied, declaring it was the custom in the Low Countries, and that although it was true, that no English general had ever before exercised this right, yet it had been for the simple reason, that no English general had ever before been commander-in-chief in the Low Countries. Walpole, unjustly included in the same condemnation, would not defend himself, and in consequence was confined in the Tower, as a prisoner, until the end of the session.
