The King having resolved to add to the regular army a regiment of dragoons for permanent service, Colonel Churchill was commissioned to raise a troop of dragoons, and was appointed colonel of the regiment, which was honoured with the distinguished title of the ROYAL REGIMENT OF DRAGOONS. He was also advanced to the peerage of Scotland by the title of Baron Churchill of Aymouth. Soon after the accession of King James II. he was created an English peer by the title of Baron Churchill of Sandridge. On the 14th of May, 1685, he was promoted to the rank of brigadier-general: on the breaking out of the rebellion of the Duke of Monmouth he was sent, with a body of cavalry, to the west of England, and he was second in command at the battle of Sedgemoor. His meritorious conduct during this rebellion was rewarded with the colonelcy of the third troop of life guards, and the rank of major-general. No ties of interest, or charms of royal favour, could, however, induce him to abandon the best interests of his native country; and at the Revolution in 1688 he joined the standard of the Prince of Orange, for which he was removed from the life guards by King James. On the accession of King William III. he was restored to the command of the third troop of life guards,--appointed colonel of the royal fusiliers,--sworn a member of the privy council,--made lord of the bedchamber to his Majesty,--created EARL OF MARLBOROUGH, and appointed to the command of the British troops sent to the Netherlands, to be employed in the war with France. During the campaign of 1689 he served under Prince Waldeck, and gave proof of his personal bravery, and ability to command, at the battle of Walcourt. In June, 1690, he was appointed commander-in-chief, and proceeding, in the autumn of that year, with a body of troops to Ireland, captured Cork and Kinsale. In 1691 he commanded the British infantry under King William in the Netherlands. In the following year he was confined in the Tower of London on a charge of high treason; but was subsequently released without being brought to trial, and restored to royal favour. On the breaking out of the war in 1701, he was selected by King William to command the British forces sent to the Netherlands, and to negotiate the treaties to be formed with foreign powers; and he was appointed colonel of a regiment of foot (now twenty-fourth). Queen Anne confirmed these appointments; also advanced him to the post of captain-general of her forces, and procured him the chief command of the united British, Dutch, and auxiliary troops. At the head of these forces he evinced the abilities of a great captain; he forced the enemy to take shelter behind their lines; took Venloo, Ruremonde, Stevenswaert, and Liege with surprising rapidity; extended and secured the Dutch frontiers; and was rewarded with the thanks of parliament, the approbation of his sovereign, and the dignity of DUKE OF MARLBOROUGH.
