Such aggression, failure though it was, naturally led the English to make reprisals; and in September a British squadron sailed from Spithead with four thousand troops on board for a descent on the Spanish coast. The original object of the expedition had been an attack on Corunna, but Lord Cobham,[9] who was in command, thought the enterprise too hazardous, and turned his arms against Vigo. The town being weakly held was at once surrendered, and the citadel capitulated after a few days of siege. A considerable quantity of arms and stores, which had been prepared for Ormonde's expedition, was captured, and with this small advantage to his credit, Cobham re-embarked his troops for England.[10] Shortly afterwards Alberoni opened negotiations for peace, which he purchased at the cost of his own dismissal. The treaty was signed on the 19th of January 1720, and England entered upon twenty years of unbroken peace. [Sidenote: 1722.] But before I touch upon the history of that peace I may be allowed to advance two years to record an event which may fittingly close the first thirty years of conflict with Jacobitism and its allies. On the 16th of June 1722 died John, Duke of Marlborough. Constantly during his later campaigns he had suffered from giddiness and headache, and in May 1716 the shock caused by the death of his daughter, Lady Sunderland, brought on him a paralytic stroke. He rallied, but was struck down a second time in November of the same year; and although, contrary to the received opinion, he again rallied, preserving his speech, his memory, and his understanding little impaired, yet it was evident that his life's work was done. In the few years that remained to him he still attended the House of Lords, spending the session of 1721 as usual in London, and retiring at its close to Windsor Lodge. There at the beginning of June in the following year he was smitten for the third time, and after lingering several days, helpless but conscious, he at dawn of the 16th passed peacefully away. On the 14th of July the body was brought to Marlborough House. In those days London was empty at that season, and only in Hyde Park, where the whole of the household troops were encamped, was there sign of unusual activity. Day after day the Foot Guards were drilled in a new exercise to be used at the funeral; the weeks wore on, the day of Blenheim came and went, and at length on the 9th of August all was ready. From Marlborough House along the Mall and Constitution Hill to Hyde Park Corner, from thence along Piccadilly and St. James's Street to Charing Cross and the Abbey, the way was lined with the scarlet coats of the Guards. The drums were draped in black, the colours wreathed with cypress; every officer wore a black scarf, and every soldier a bunch of cypress in his bosom. Far away from down the river sounded minute after minute the dull boom of the guns at the Tower.
