The legend as told by Tschudi (ca. 1570) goes as follows: William Tell, who originally came from Bürglen, was known as a strong man, mountain climber, and an expert shot with the crossbow. In his time, the Habsburg emperors of Austria were seeking to dominate Uri. Albrecht (or Hermann) Gessler, the newly appointed Austrian Vogt of Altdorf, raised a pole in the village's central square, hung his hat on top of it, and demanded that all the townsfolk bow before the hat.

On 18 November 1307, Tell visited Altdorf with his young son and passed by the hat, publicly refusing to bow to it, and so was arrested. Gessler - intrigued by Tell's famed marksmanship, yet resentful of his defiance - devised a cruel punishment: Tell and his son would be executed, but he could redeem his life by shooting an apple off the head of his son, Walter, in a single attempt. Tell split the apple with a bolt from his crossbow.

But Gessler noticed that Tell had removed two crossbow bolts from his quiver, not one. Before releasing Tell, he asked why. Tell replied that if he had killed his son, he would have used the second bolt on Gessler himself. Gessler was angered, and had Tell bound.

Tell was brought to Gessler's ship to be taken to his castle at Küssnacht to spend his newly won life in a dungeon. But, as a storm broke on Lake Lucerne, the soldiers were afraid that their boat would founder, and unbound Tell to steer with all his famed strength. Tell made use of the opportunity to escape, leaping from the boat at the rocky site now known as the Tellsplatte.
