This and not as yet a corrupt liking for mercenary service was the original occasion of the campaigns of the confederates in Italy. The battles of Arbedo and Gierniko were fought in support of brethren whom they were bound by oath to help. But by long-continued habit the view, that what was passing on the other side of Gotthard could not be indifferent to their own land, took firm root in the minds of the Swiss statesmen, and therefore it was, that the scandalous game of intrigue and bribery, begun by Louis XI, by which France aimed at the destruction of the Swiss national character, had a good opportunity of unfolding itself on Italian ground, where France under Charles VIII and Louis XII, contrived to increase her own power, by arraying Switzers against Switzers. Nevertheless, there were yet, even in the beginning of the sixteenth century, some among the Swiss soldiers, engaged in the Italian campaigns, who were animated by motives nobler than a thirst for gold or plunder. The duty of upholding sworn treaties, and the hope of working out a lasting peace for a frontier so exposed to invasion might have prompted the more distinguished, but very often the common soldiers were only stimulated by a love for weapons streaming with blood. The betrayal of Ludovico Sforza, surnamed Il Moro, at Novara, in 1501, had indeed greatly shaken the confidence, hitherto nearly universal, in the fidelity and honor of the Swiss; but even at home indignation was awakened by it, a severe examination instituted, and the chief actor executed at Altorf. Indeed it seems generally to have roused the better feelings of the nation. An oath was demanded against the acceptance of pensions and mercenary service under foreign lords; and a levy was not only refused to the French ambassadors, who had come into the country with new bribes, but their safe-conduct even was recalled. Although such things were enacted by their diet, yet corrupt leaders again practised their lures, and a crowd of reckless youth again gave ear to them. But when France, now strongly established in her domination over Italy by the repeated aid of these deserters, began by degrees to treat them more coldly, and in the end with contempt even, they appear to have become more wise. Instead of remaining quiet within their own borders, they gave free rein to a growing national hatred, which the Emperor and then the Pope, Julius II, well understood how to turn to their own profit.
