Background
Mowbray was descended from a sister of the last earl of the previous creation.
Mowbray was descended from a sister of the last earl of the previous creation.
In 1451 the earldom of Surrey was revived for him. In 1461 he succeeded his father as 4th Duke of Norfolk and hereditary Earl Marshal. He continued his father"s efforts to possess Caister Castle, finally taking it in September 1469 after a siege.
Under pressure from the Church, Norfolk did at least grant the other defenders a safe conduct.
In 1476, within a day of Norfolk"s death, the Paston family took Caister back again. Norfolk was invested as a Knight of the Garter in 1472.
He died very suddenly, having apparently been in good health the day before. They had only one child, Anne de Mowbray, 8th Countess of Norfolk, and so the 1397 creation of the dukedom became extinct upon his death.
Anne, who was only 3 years old when her father died, inherited his extensive lands and wealth.
The dukedom would be recreated in 1481 and again in 1483. The 1483 creation survives to the present day.
Despite the fact that John Paston, who was in charge of defending Caister, had been in his service for several years, he showed a notable ruthlessness in his conduct of the siege, in which one Daubenay, a long-standing Paston servant, was killed.
