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 1402)
On 25 October 1382 Walter Devereux, his father (Sir Walter Devereux), Sir John Devereux, and Sir John de Burley were placed under a recognizance of 400L to Sir John Crophul. On 4 November 1282 John Crophul was granted license following the payment of 20 marks to enfoeff Walter and Agnes Devereux in the manor of Newbold Verdon in Leicestershire. Following John Crophul's death on 3 July 1383, Agnes (age 12) was identified as Walter Devereux's wife. Wardship of Agnes had been assigned to Roger Crophul. On 21 August 1383 Roger Crophul and Thomas Melton granted to Walter Devereux the keeping of all the lands of the late John Crophul except the manors of Hemington, Braunstone, and Bonington until the lawful age of his wife. Joan, widow of John Crophul's son Thomas, was assigned Market Rasen as her dower on 20 September 1383. After the widow's death and Agnes’ coming of age on 27 September 1385, Walter Devereux took possession of the remaining Crophul lands by right of marriage. These included Weobley manor (Herefordshire); Sutton Bonington manor and lands at Arnold (Nottinghamshire); the manors of Navenby, Cotesbach, Braunstone, and Hemington (Leicestershire); and an estate at Market Rasen (Lincolnshire). Weobley would become his principal residence.
