The war thus begun was prosecuted for five succeeding years with the full energy of both nations. The period was one of suffering and anxiety to the colonists, who, knowing the full extent of their danger, spared no exertion to avert it. In the year 1758, Lord Abercrombie, who then commanded in America, had at his disposal a force amounting to fifty thousand men, of whom the greater part were provincials.[121] The operations of the war embraced a wide extent of country, from Cape Breton and Nova Scotia to the sources of the Ohio; but nowhere was the contest so actively carried on as in the neighborhood of Lake George, the waters of which, joined with those of Lake Champlain, formed the main avenue of communication between Canada and the British provinces. Lake George is more than thirty miles long, but of width so slight that it seems like some broad and placid river, enclosed between ranges of lofty mountains; now contracting into narrows, dotted with islands and shadowed by cliffs and crags, now spreading into a clear and open expanse. It had long been known to the French. The Jesuit Isaac Jogues, bound on a fatal mission to the ferocious Mohawks, had reached its banks on the eve of Corpus Christi Day, and named it Lac St. Sacrement. Its solitude was now rudely invaded. Armies passed and repassed upon its tranquil bosom. At its northern point the French planted their stronghold of Ticonderoga; at its southern stood the English fort William Henry, while the mountains and waters between were a scene of ceaseless ambuscades, surprises, and forest skirmishing. Through summer and winter, the crack of rifles and the cries of men gave no rest to their echoes; and at this day, on the field of many a forgotten fight, are dug up rusty tomahawks, corroded bullets, and human bones, to attest the struggles of the past.
