Anne's position grew tenuous as her relationship with Henry became strained. After everything he did to marry her, she still hadn't produced his male heir. His wandering eye continued wandering and alighted upon a certain Jane Seymour. Now with Katherine dead, he was, in the eyes of Catholics, a widower and free to marry again. But his split with Rome posed a problem because Anne was very much alive and their marriage very much valid, having been confirmed by an Act of Parliament.
Henry had an ally in his chief advisor and secretary, Thomas Cromwell. Anne and Cromwell were basically enemies, and Cromwell openly admitted to plotting to bring down Anne. He just needed a case against her. Luckily for him, Anne was known for having a flirtatious personality and a loose tongue. She had made several indiscreet comments in jest, but these bordered on treason. Cromwell heard about this exchange just after another falling out with Anne, so he pounced on the chance to bring her down.
The case against Anne was whirlwind, indeed. Cromwell later told Eustace Chapuys, ambassador to the court of Emperor Charles V, that he conceived the idea of her disgrace and destruction on April 18, 1536. He secretly began working with Henry's Council members and investigated her household. Anne was arrested on May 2, 1536, after attending the May Day celebrations with Henry. She was never to see her husband again. The last few chapters document in depth her imprisonment and trial. Apparently, Henry was reasonably convinced of the case and evidence presented against Anne, so he intensified his courtship of Jane Seymour.
Anne and the five men accused with her (including her brother, George) were found guilty of treason and sentenced to death. Anne was executed on May 19, 1536, a month and a day after Cromwell's planning and machinations. Henry spent the day, rather indecently, with Jane Seymour. The two were betrothed and married within weeks of Anne's execution. Anne ultimately triumphed: Jane bore Henry his long-awaited son, but Edward died around the age of 15. Elizabeth I eventually succeeded to the throne and reigned brilliantly for 45 years.
