The next month Pitt despatched a smaller fleet and force to destroy the port of Cherbourg, which the French had constructed under Cardinal Fleury, and, as they stated by an inscription, "for all eternity." This time the command was given to General Bligh. Howe was admiral, and on board with him went Prince Edward, afterwards Duke of York. On the 8th of August the troops were landed at Cherbourg, which was deserted by the garrison, and they destroyed the forts and harbour, demolished a hundred and seventy pieces of iron cannon, and carried off twenty-two fine brass ones. After re-embarking and returning to Portsmouth, Bligh was ordered to pay another visit to St. Malo, but still found it too strong for him; yet he landed his men in the bay of St. Lunaire, about two leagues westward of St. Malo; and the weather immediately driving Howe to sea, the army was marched overland to St. Cast, some leagues off. The soldiers were allowed to rove about and plunder, till Bligh heard that the Duke of Aiguillon was advancing against them at the head of a strong force. Bligh then, but in no hurry, marched for the port of St. Cast, followed by Aiguillon, who waited till he had embarked all but one thousand five hundred men, when he fell upon them, and slaughtered a thousand of them in a hollow way amongst the rocks leading down to the shore. In Germany, Prince Ferdinand of Brunswick, after driving the French out of Hanover, had followed them across the Rhine this spring, and on the 23rd of June defeated them at Crefeld, with a slaughter of six thousand men. He then took Düsseldorf; but the French court recalling the incapable Clermont, and sending Marshal De Contades with fresh forces against him, and Prince Soubise defeating the Hessians, he was obliged to fall back into Westphalia, where he was joined by the Duke of Marlborough and Lord George Sackville with the English auxiliaries, but too late to effect anything further. Shortly afterwards the Duke of Marlborough died suddenly, under strong suspicions of having been poisoned.
