One day while riding with an armed escort through the canton of Schwytz, he noticed a comfortable-looking dwelling which was being built by one Werner Stauffacher. Turning to his followers, he cried, "Is it not shameful that miserable serfs like these should be permitted to build such houses when huts would be too good for them?" "Let this be finished," said his chief attendant; "we shall then sculpture over the gate the arms of the emperor, and a little time will show whether the builder has the audacity to dispute possession with us." The answer pleased Gessler, who replied, "Thou art right," and, planning future vengeance, he passed on with his escort.

The wife of Stauffacher, who had been standing near the new building, but concealed from Gessler and his men, heard the conversation, and reported it to her husband. The latter, filled with indignation, without uttering a word, arose and started for the home of his father-in-law, Walter Furst, in the village of Attinghaussen.

On his arrival Staffaucher was cordially welcomed by his father-in-law, who placed refreshments before him, and waited for him to explain the object of his visit. Pushing aside the food, he said, "I have made a vow never again to taste wine or swallow meat until we cease to be slaves." Stauffacher then related what had happened. Furst's anger was kindled by the recital. Both men were roused to such a pitch that they resolved, then and there, to free themselves and their countrymen from the chains which bound them, or die in the attempt. They conversed far into the night, making plans for the gaining of national independence. Then they sought out in his hiding-place Arnold of Melchthal, the young peasant whom Landenberg had so cruelly persecuted. In him they found, as they expected, an ardent supporter of their plans.

The three conspirators, Stauffacher, Furst, and Melchthal, represented different cantons; one belonging to Schwytz, another to Uri, and the third to Unterwalden. They hoped to form a league and unite the three cantons against the power of Austria. In pursuance of their plans, each pledged himself to select from among the most persecuted and the most daring in their respective cantons ten others to join them in the cause of liberty.

On the night of November 7, or 17 (the date is variously given), in the year 1307, the confederates met together in a secluded mountain spot called Rutli. There they bound themselves by an oath, the terms of which embodied their purpose: "We swear in the presence of God, before whom kings and people are equal, to live or die for our fellow-countrymen; to undertake and sustain all in common; neither to suffer injustice nor to commit injury; to respect the rights and property of the Count of Hapsburg; to do no violence to the imperial bailiffs, but to put an end to their tyranny." They fixed upon January 1, 1308, as the day for a general uprising.

Events were gradually shaping themselves for the appearance of William Tell on the scene. Up to this time his name does not appear in the annals of his country. The bold peasant of Uri was so little prominent among his countrymen that, according to some versions of the legend, although a son-in-law of Walter Furst, he had not been chosen among the thirty conspirators summoned to the meeting at Rutli. This, however, is contradicted by another, which asserts that he was "one of the oath-bound men of Rutli."

The various divergences in the different versions of the legend do not affect its main features, on which all the chroniclers are agreed. It was the crowning insult to his country which indisputably brought Tell into prominence and made his name forever famous.

Gessler's hatred of the people daily increased, and was constantly showing itself in every form of petty tyranny that a mean and wicked nature could devise. He noticed the growing discontent among the peasantry, but instead of trying to allay it, he determined to humiliate them still more. For this purpose he had a pole, surmounted by the ducal cap of Austria, erected in the market square of the village of Altdorf, and issued a command that all who passed it should bow before the symbol of imperial rule. Guards were placed by the pole with orders to make prisoners of all who refused to pay homage to the ducal cap.

William Tell, a bold hunter and skillful boatman of Uri, passing by one day, with his little son, Walter, refused to bend his knee before the symbol of foreign oppression. He was seized at once by the guards and carried before the bailiff.

There is considerable contradiction at this point as to whether Tell was at once carried before the bailiff or bound to the pole, where he remained, guarded by the soldiers, until the bailiff, returning the same day from a hunting expedition, appeared upon the scene. Schiller, in his drama of "William Tell," adopts the latter version of the story.
