Walter Devereux (1387–1419)
Walter Devereux assumed a position in the retinue of Henry IV following the death of his father on 25 July 1402 at the Battle of Pilleth. On 13 December 1402 Sir Edmund Mortimer declared his rebellion against Henry IV, but Devereux stayed loyal to the king. He was probably present at the Battle of Shrewsbury on 21 July 1403, and subsequently was knighted. Sir Walter Devereux was placed on a Commission of array for Herefordshire on 8 September 1403 to raise troops for the defense against the king’s enemies who have lately invaded the realm. It is probable that Devereux was present when Henry IV faced off with a combined Welsh and French force in South Wales during the summer of 1405, but no major battle occurred and the English force had dispersed by October of that year. Devereux remained an important supporter of the efforts to suppress the rebellion in Wales as Prince Henry assumed responsibility for the fight. Walter Devereux would be among 14 men below the rank of baron who would be retained for life by Prince Henry (the future Henry V).
Walter Devereux (died c. 1383)
Following the death of Humphrey de Bohun on 10 January 1373, Walter Devereux was shown holding 1 fee in Bodenham at his inquiry post-mortem. Devereux was granted the custody of all castles and keeping of all the forests, chases, and parks in Wales and the Marches, which had been held by the said Earl, while they remained in the king's hands. On 16 July Walter Devereux; John ap Rees, and Richard Sergeant were appointed to collect for one year the issues and profits of all castles, lordships and lands in England and the Welsh Marches of the earl of Hereford to be used for the payment of the debts of both Humphrey de Bohun and his father, William de Bohun, earl of Northampton.
