In November, the main body of the troops on either side went back into winter quarters, and Fort William Henry was left in charge of a small garrison of between 400 and 500 men, belonging to the 44th Regiment and the Rangers, commanded by Major Eyre. In the early spring of 1757, an attempt was made to surprise them by an expedition sent up from Montreal under the command of Rigaud de Vaudreuil, brother of the Governor of Canada. The attacking force started towards the end of February, and on March 19 appeared before the fort. The next day they offered terms of surrender, which were refused; and, after vainly attempting to reduce the fort till the twenty-fourth, they retreated down Lake George, having burnt some boats and outbuildings, but otherwise inflicted little loss. [Sidenote: _Loudoun's abortive expedition against Louisbourg._] The spring came on, and the early summer, and Loudoun matured a plan, which he had formed for attacking Louisbourg in force, as a preliminary to a further attack on Quebec. {263} His plan was accepted in London, and the Government determined to send out a strong fleet to co-operate with him, the rendezvous to be the harbour of Halifax. Like previous schemes of the same kind, the enterprise failed through untoward delays. The fleet under Admiral Holborne, consisting of fifteen ships of the line, and conveying transports with from 5,000 to 6,000 men on board, did not sail till May 5, and did not reach Halifax till early in July. Loudoun, meanwhile, had drawn off the bulk of his troops, including Rogers and his Rangers, from the New York frontier; and, after vainly waiting at New York for news of the English Admiral, set sail for Halifax on June 20, reaching his destination on the last day of that month. The combined forces were nearly 12,000 strong, but the time for attack had gone by. Hearing of the English preparations, the French Government had sent a fleet at least as strong as Holborne's across the Atlantic, under Admiral La Motte; and the English commanders learnt that Louisbourg was being defended by ships as numerous as their own, and by a garrison in which the troops of the line alone were said to number 6,000 men. The enterprise was accordingly abandoned. In the middle of August Loudoun re-embarked the majority of his troops for New York. Holborne twice reconnoitred Louisbourg in the hope of bringing on a sea-fight. The second time, in the middle of September, a storm shattered his vessels, and the whole expedition utterly collapsed.[13] 'It is time,' wrote Horace Walpole[14] in despondent terms, 'for England to slip her own cables and float away into some unknown ocean.' On {264} his way back to New York, Loudoun was met with bad news--that Fort William Henry had fallen.
