The knight raped a young woman, according to the “statute” or laws of that time, what was to be his punishment?

King Arthur had a knight who, when riding home one day from hawking, found a maiden walking alone and raped her. This crime usually held the penalty of death, but, in court, the queen intervened and begged her husband to spare the knight, promising the knight that she would grant his life if he could answer the question "What do women most desire?" She gave him one year to find the answer.
