Anne Boleyn a tournament and knocked unconscious for two hours, a worrying incident that Anne believed led to her miscarriage five days later. Another possible cause of the miscarriage was an incident in which, upon entering a room, Anne saw Jane Seymour sitting on Henry's lap and flew into a rage. Whatever the cause, on the day that Catherine of Aragon was buried at Peterborough Abbey, Anne miscarried a baby which, according to the imperial ambassador Eustace Chapuys, she had borne for about three and a half months, and which "seemed to be a male child". Chapuys commented "She has miscarried of
Katherine Anne Porter Fools" for $500,000). Producer David O. Selznick was after the film rights; but United Artists who owned the property, demanded $400,000. The novel was adapted for film by Abby Mann; producer and director Stanley Kramer featured Vivien Leigh in her final film performance. Despite Porter's claim that after the publication of "Ship of Fools " she would not win any more prizes in America, in 1966 she was awarded the Pulitzer Prize and the U.S. National Book Award for "The Collected Stories of Katherine Anne Porter". That year she was also appointed to the American Academy of Arts and Letters.
