The forecast and the dejection of Charles were not unreasonable. It will be found that there is special mention made, in the chronicles of the ninth and tenth centuries, of forty-seven incursions into France of Norwegian, Danish, Swedish, and Irish pirates, all comprised under the name of Northmen; and doubtless many other incursions of less gravity have left no trace in history. "The Northmen," says Fauriel, "descended from the north to the south by a sort of natural gradation or ladder. The Scheldt was the first river by the mouth of which they penetrated inland; the Seine was the second; the Loire the third. The advance was threatening for the countries traversed by the Garonne; and it was in 844 that vessels freighted with Northmen for the first time ascended this last river to a considerable distance inland, and there took immense booty. The following year they pillaged and burnt Saintes. In 846 they got as far as Limoges. The inhabitants, finding themselves unable to make head against the dauntless pirates, abandoned their hearths, together with all they had not time to carry away. Encouraged by these successes the Northmen reappeared next year upon the coasts and in the rivers of Aquitaine, and they attempted to take Bordeaux, whence they were valorously repulsed by the inhabitants; but in 848, having once more laid siege to that city, they were admitted into it at night by the Jews, who were there in great force; the city was given up to plunder and conflagration; a portion of the people was scattered abroad, and the rest put to the sword."
