two occasions: in 1440 and in 1448. The first saw him bound over for the significant amount of £10,000, and confined to living within the royal Household, preventing him from returning to seek revenge in East Anglia. Likewise, apart from an appointment to commissions of oyer and terminer in Norwich in 1443 (after the suppression of Gladman's Insurrection), he received no other significant offices or patronage from the crown. A recent biographer of Mowbray's, the historian Colin Richmond, has described this as Mowbray's "eclipse". Richmond suggests that soon after his last imprisonment in 1449, Mowbray undertook a pilgrimage to Rome; a licence for him to do so had been granted three years earlier. De la Pole fought back with what one contemporary labelled "greet hevyng an shoving." He was successful in doing so. Within a couple of years, Mowbray could not protect his retainers as he had previously done. A Paston letter tells how Robert Wingfield, who was involved in a bitter dispute with one Robert Lyston, "procured and exited the wurthi prince the Duke of Norffolk to putte oute ageyn the seid Robert Lyston" from the latter's Suffolk manors. Lyston, with de la Pole's support, repeatedly sued Wingfield until in 1441 Wingfield was imprisoned in the Tower of London. In 1440, Mowbray was able to influence the Exchequer to quash Wingfield's fines; but Mowbray's success was fleeting. Mowbray was more successful in his support of John Fastolf—in one of the latter's many lawsuits 1441, and was able to impose an advantageous settlement (for Fastolf) in Chancery. Generally, though, says Helen Castor, Mowbray's influence "proved woefully inadequate" to protect and defend his retainers and tenants to the degree they could reasonably expect from their lord. It was his supporters' misfortune, one historian has said, that "Norfolk's power never matched the status attributed to him". Mowbray's personal and political situation did not improve over the following decade. Between 1440 and 1441 he was imprisoned in the Tower following a dispute with John Heydon, who was close to de la Pole. Mowbray was bound over on 2 July 1440 for the "enormous" sum of 10,000 marks, had to reside in the King's household, while swearing no further harm to Heydon. Crime and disorder in East Anglia In 1443 Mowbray and Wingfield fell out over Hoo manor. Wingfield had received Hoo from Mowbray's father, but Mowbray wanted it returned. The dispute fell into
