Walter Devereux (1411–1459)
Following the death of Edmund Mortimer, 5th Earl of March, on 18 January 1425, Richard, 3rd Duke of York inherited his estates along the Welsh Marches. This brought Walter Devereux into the retinue of the Duke, and he remained his loyal supporter throughout the War of the Roses. Devereux had been knighted by 22 September 1429 when he first represented Herefordshire in Parliament. He probably was in attendance on the Duke when he travelled with Henry VI to France for his coronation on 16 December 1429. On his return Devereux represented Herefordshire again in Parliament on 16 January 1430. He was listed on the subsidy rolls for Herefordshire of 12 January 1431 as holding his 1/3 of half a fee in Byford.
Walter Devereux (died 1402)
In the “Wonderful Parliament” of 1 October 1386 Richard II was forced to accept a commission of 11 members to control the royal household for 1 year to counter growing anger with his financial excesses. Walter's cousin and ally, Baron John Devereux, was a member of the commission. The Lords Appellant led this movement and included Thomas of Woodstock, Duke of Gloucester; Richard FitzAlan, Earl of Arundel; Thomas de Beachamp, Earl of Warwick; and later Henry Bolingbroke, Earl of Derby; and Thomas de Mowbray, Earl of Nottingham. The Earl of Arundel was appointed admiral of the fleet on 10 December 1386, and Sir Walter Devereux served under Captain Sir Thomas Mortimer in his naval expedition. Arundel took command of the fleet on 16 March 1387 at Sandwich, and led them in the Battle of Cadsand on 24 March. Fought off Margate, the English were victorious over a Franco-Flemish fleet ending the threat of a French invasion. The English pursued the remnants of the enemy to Sluis, and then pillaged the surrounding countryside before bringing the fleet back to England on 14 April. They then made another foray to Brest in Brittany before returning to England in June 1387.
