Beauchamp was the second son of Sir John Beauchamp of Powick, Worcestershire. In his youth, Beauchamp studied the law although he became distinguished as a soldier displaying great gallantry at the Battle of Agincourt. As a younger son, Walter didn't enjoy the possessions of his families chief estates positioned in Worcestershire and Warwickshire. Walter did however use his families connections at court, getting retained by Thomas of Woodstock, Duke of Gloucester in May 1392 for services in Ireland. Upon his return to England, Beauchamp is believed to have rendered some service to Henry IV prior to his coronation on 23 October 1399 because only ten days after he received a grant of as much as £40 a year for life or until he was provided with lands to that value. The later of which was granted in August 1400 when he and his bride assumed ownership for the term of their lives the duchy of Lancaster manors of Easterton and Berwick St. James in Wiltshire.
Royal service
Following his acquisition of the duchy of Lancaster manors, Beauchamp was serving as an esquire of the royal household. It is likely that he fought for the king at Shrewsbury in 1403 and campaigned in the north against Archbishop Scrope and the earl of Northumberland in 1405. In 1415 he served as a king's knight in the royal army in France, as part of the retinue of Humphrey, Duke of Gloucester.
Career in politics
He was appointed High Sheriff of Wiltshire for 1403 and 1407. On his return from France after the Battle of Agincourt he entered parliament in 1416 as Knight of the Shire for Wiltshire and on 16 March 1415/6 was chosen speaker of the House of Commons. However, Sir Walter did not hold the office long, as parliament was dissolved in the same year. In 1417 he served in France again and was at Rouen after its capture in 1419. He remained in Normandy for two years, on his return becoming treasurer of the royal household, treasurer at war and one of the executors of Henry V's will in June 1421. Shortly afterwards he passed into the service of Queen Catherine as steward of her household. He was also selected as one of the commoners to assist in the protection of the young Henry VI. He was employed as counsel by his relative, Richard Beauchamp, earl of Warwick, to argue his claim of precedency before the House of Commons. This quarrel between the Earl of Warwick and John Mowbray, earl marshal, which took up much of the time of the session of 1425, was terminated by the restoration of the forfeited dukedom of Norfolk to Mowbray. In 1429 he was made Master of the Horse.
