Walter Devereux, 7th Baron Ferrers of Chartley
Walter Devereux was with the army as Edward IV marched north, and fought in the victory at the Battle of Towton on 29 March 1461, where he was knighted. On 8 July Devereux was appointed Justice of the Peace, and place on the Commission of Array for Herefordshire, Gloucestershire, and Shropshire to raise troops to stamp out Lancastrian resistance in Wales. He was also placed on a commission of Oyer and terminer to inquire into all treasons, insurrections and rebellions in South Wales, and granted the authority to receive submission into the king's peace of rebels. In September Walter Devereux met with the king and William Herbert at Ludlow Castle where they were assigned to take into the king's hands all the castles, lordships, manors, land and possessions of the late Humphrey, Duke of Buckingham, in South Wales. On 30 September 1461, Herbert and Devereux captured Pembroke Castle. On 16 October Herbert and Devereux defeated the Lancastrians under Pembroke and Exeter at the Battle of Twt Hill, effectively ending resistance in Wales. Walter Devereux attended Parliament on 4 November 1461, but was back in Wales for the capture of Denbigh Castle in January 1462.
Walter Devereux, 7th Baron Ferrers of Chartley
In 1468 Edward IV announced his intent to invade France. On 3 August 1468 Walter Devereux was assigned to muster at Gravesend with his men for service overseas, but other events in the kingdom prevented this from occurring. On 12 February 1469 he was commanded to deliver prisoners to the gaol of Hereford Castle. On 22 May he was appointed to a commission of Oyer and terminer for the counties of York, Cumberland, and Westmoreland; and the city of York. He was probably at the Battle of Edgecote Moor on 26 July 1469 when the Earl of Warwick defeated King Edward, and Devereux's brother-in-law, William Herbert, was killed. Edward IV was captured, but Warwick was forced to release him within a few months. By September 1469 Walter Devereux was assigned to raise new troops for the Yorkists in Herefordshire, Gloucestershire, Shropshire, and Worcestershire. On 16 November he was rewarded with the grant of the offices of Constable of the Castles of Brecon, Hay, and Huntington; and Steward of the Lordships of Brecon, Hay, and Huntington during the minority of Henry Stafford.
