In Tschudi's account, on 18 November 1307, Tell visited Altdorf with his young son. He passed by the hat, but publicly refused to bow to it, and was consequently arrested. Gessler was intrigued by Tell's famed marksmanship, but resentful of his defiance, so he devised a cruel punishment. Tell and his son were both to be executed; however, 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. Gessler then noticed that Tell had removed two crossbow bolts from his quiver, so he asked why. Tell was reluctant to answer, but Gessler promised that he would not kill him; he replied that, had he killed his son, he would have killed Gessler with the second bolt. Gessler was furious and ordered Tell to be bound, saying that he had promised to spare his life, but would imprison him for the remainder of his life.
