At the period these events were in progress, or, rather, about the time that the Austrian bailies were expelled, toward the close of the thirteenth century, the Emperor's[45] attention was too fully occupied conducting a war against the Bishop of Basel to allow him to enforce his authority among the revolted Waldstaette. He did not, however, allow the peasants for long to enjoy the fruits of their energetic and successful action, as some six months later he headed a large army with which he intended to enforce obedience. The expedition thus begun led to Albert's tragic death, and reared another step leading to the final independence of the Swiss. On reaching Baden, in the Aargau, a halt was made in order to deliberate on the best mode of punishing the rebels. Here a general council of nobles decided, after careful deliberation, on the route to be taken, and the nature of the measures best calculated to enforce Albert's authority. On May 1, 1308, the Emperor, with a few followers, returned to Rheinfelden, in order to visit the Empress Elizabeth, preparatory to marching against the Waldstaette. Shortly before this time Albert had had a violent quarrel with his nephew John, son of Duke Rudolph of Swabia, touching the youth's paternal inheritance, which he persistently declined to allow John to take possession of, and whom he had, moreover, publicly insulted by offering him a coronet of twigs as the only recompense for his just claims. In spite of this quarrel Albert allowed John and four of his fastest friends to occupy a place in his suite when he left Baden to visit his consort. Albert's disregard of his nephew's resentment was further shown when the party arrived on the bank of the Reuss, as he allowed him, with his friends, to accompany him in the boat in which he crossed the river. The passage was made in safety, but just as the Emperor was stepping on shore near the town of Windisch, John and three of his companions struck him down with their swords, and after inflicting a number of severe wounds left him for dead. The unhappy monarch expired a few minutes after in the arms of a passing peasant woman. All this bloody scene took place in full view of the Emperor's train on the opposite side of the river, though no one apparently was able to render him assistance, probably from the absence of boats and the suddenness of the tragedy. The murderers succeeded in making good their escape, though two of them were afterward captured and executed, as were also a number of innocent people believed to be participators in the conspiracy. John himself was more fortunate, for, disguised as a monk, he managed for many years to hide his identity, and, after wandering in Tuscany unsuspected, eventually died in a monastery at Pisa.
