In the Spring and Summer of 1075, the Earls of Norfolk and Hereford were conspiring to seize England for themselves, and they enticed Waltheof to join in. He quickly changed his mind, and reconciled with the King, who treated the matter lightly, but at Christmas 1075, Waltheof was brought to trial, his wife (the King's niece) being a witness against him. When the trial resumed in May Waltheof was found guilty and beheaded on St. Giles's Hill.
