Edward of Norwich , 2nd Duke of York Edward of Langley , 2nd Duke of York , KG ( c . 1373 – 25 October 1415 ) , was the eldest son of Edmund of Langley , 1st Duke of York , by his first wife Isabella of Castile , and the grandson of Edward III . He held significant appointments during the reigns of three monarchs Richard II , Henry IV , and Henry V , and was slain at the Battle of Agincourt in 1415 . He translated a hunting treatise , " The Master of Game " . Family . Edward of Langley was born c . 1373 , likely at Langley , now Kings Langley in Hertfordshire , the eldest son of Edmund of Langley , 1st Duke of York , and his first wife , Isabella of Castile , second daughter of Peter the Cruel and his favourite mistress , Maria de Padilla . He had a sister , Constance , and a younger brother , Richard , 3rd Earl of Cambridge . According to Cokayne , a French chronicle offers the only support for the modern assertion that Edward was styled ' of Norwich ' , and both Cokayne and Horrox suggest that the phrase ' de Norwik ' found therein is a corruption or misreading of ' Deverwik ' , the usual French rendering for the phrase ' of York ' at the time . Reign of Richard II . Edward was knighted at the coronation of his cousin , Richard II , on 16 July 1377 , and in May 1387 was admitted to the Order of the Garter . He was close to the King throughout his life , and benefited even in his youth from numerous royal grants and appointments . On 25 February 1390 the King created him Earl of Rutland , and on 22 March 1391 made him admiral of the northern fleet , and sole admiral the following November . In 1392 he became a member of King Richard ' s council , and was with the King during a campaign in Ireland in 1394 - 5 , prior to which , although no patent has been found , he was created Earl of Cork . He used the styles of Rutland and Cork throughout the remainder of his life . In the late 1390s he was sent on embassies to France and to the Count Palatine , and was appointed to numerous offices including Constable of Dover Castle , Lord Warden of the Cinque Ports , Keeper of the Channel Islands , Constable of the Tower , Warden of the New Forest , Keeper of Carisbrooke Castle and Lord of the Isle of Wight . On 11 July 1397 Richard II arrested his uncle , Thomas of Woodstock , 1st Duke of Gloucester . Rutland was granted Gloucester ' s office of Constable of England on 12 July , and was one of an eight - member commission which on 5 August determined to accuse Gloucester , the Earl of Warwick , and the Earl of Arundel of high treason . Rutland was later accused of having sent his servants to assist in Gloucester ' s subsequent murder at Calais , an allegation he denied . However on 28 September 1397 he received a large grant of Gloucester , Warwick and Arundel ' s forfeited lands , and on 29 September was created Duke of Aumale , a title which had earlier been granted to Gloucester on 3 September 1385 . On 16 September 1398 Aumale presided as constable over the aborted judicial combat between Henry Bolingbroke , the future Henry IV and Thomas Mowbray , 1st Duke of Norfolk , which ended with Bolingbroke and Norfolk being sent by King Richard into exile . Additional royal grants followed during the final years of King Richard ' s reign . On 10 February 1398 Aumale was appointed Warden of the West March . On 11 August 1398 he was granted custody of the lands of Roger Mortimer , 4th Earl of March , during the latter ' s minority , and on 20 March 1399 lands which had lately belonged to John of Gaunt , 1st Duke of Lancaster , and which were part of the inheritance of his son , Henry Bolingbroke , the future King Henry IV . In May 1399 Aumale accompanied King Richard to Ireland , and in the King ' s absence , Bolingbroke landed , towards the end of June , near Ravenspur , Yorkshire , with a small band of exiles . During the following three weeks Bolingbroke ' s forces were augmented by loyal Lancastrian supporters and were soon joined by the most powerful of the northern magnates , the Earls of Northumberland and Westmorland . King Richard ' s fatal decision to divide his army while still in Ireland has been attributed to advice from Aumale . The King sent some of his troops on ahead to North Wales under the command of the Earl of Salisbury , and about 19 July arrived at Milford Haven in South Wales with the rest of his forces . News of the strength of Bolingbroke ' s army then caused the King to desert the troops which were with him and travel to North Wales in an attempt to join Salisbury . However Salisbury ' s troops , having heard rumours of the King ' s death , had dispersed , and the army left behind by the King did so as well . Although he could have made his escape by sea , the King ensnared himself in negotiations with Bolingbroke . Meanwhile Aumale ' s father , Edmund of Langley , 1st Duke of York , who had been left in charge of the kingdom during King Richard ' s absence , and had raised an army on hearing of Bolingbroke ' s landing in Yorkshire , capitulated to Bolingbroke at Berkeley on 27 July . Aumale speedily deserted to Bolingbroke as well , and was reportedly wearing Bolingbroke ' s livery when he was among those sent by Bolingbroke to the King at Flint Castle . Reign of Henry IV . After his accession King Henry IV , in response to public animosity towards King Richard ' s closest associates , deprived Rutland on 31 August of his office of Constable of the Tower . On 20 October 1399 he was imprisoned at Windsor Castle , and on 3 November deprived of the dukedom of Aumale , but not his other titles . Rutland ' s period of disfavour was not long - lasting . The King confirmed him in his offices in connection with the Channel Islands and the Isle of Wight , and by 4 December 1399 had made him a member of his council . Rutland is alleged by a French chronicler to have betrayed to the King a conspiracy at the end of 1399 by a group of Richard II ' s former favourites who planned to murder Henry IV and his sons at a tournament at Windsor Castle on 6 January 1400 . However according to Tait , contemporary English sources which describe the conspiracy make no mention of Rutland , and his role in it is open to doubt . In October 1400 the King made Rutland Keeper of North Wales , and on 5 July 1401 his lieutenant in Aquitaine . On 1 August 1402 Rutland ' s father died , and he succeeded to the Duchy of York , at which time his earldom of Rutland became extinct by the terms of its charter , although he continued to sign himself Earl of Rutland . By May 1403 he was back in England . He was employed by the King in a campaign in Wales in the fall of that year , and on 12 November was appointed Lieutenant for South Wales for three years . Both this and his appointment in Aquitaine proved very costly , and by June 1404 he had sold or pledged his plate and was contemplating mortgaging his lands to pay his troops in Wales . In February 1405 the Welsh rebel leader , Owain Glyndŵr , his son - in - law , Sir Edmund Mortimer , and Henry Percy , 1st Earl of Northumberland , entered into a tripartite indenture which proposed a threefold division of the kingdom , an agreement apparently connected to a plot to free Mortimer ' s nephew from King Henry ' s custody and carry him into Wales . On 13 February 1405 the young Edmund Mortimer and his brother , Roger , were abducted from Windsor Castle , but quickly recaptured near Cheltenham . York ' s sister , Constance , was held responsible , and accused York of involvement in the failed abduction . He at first denied the charge , but later admitted to knowledge of the conspiracy . He was arrested , and imprisoned for 17 weeks at Pevensey Castle , after which he petitioned for release , and by October was gradually being returned to favour . His lands were restored to him on 8 December 1405 , and in November 1406 he was again made Constable of the Tower and continued to serve in a military capacity in Wales . In the conflict over foreign policy between Henry IV and his heir , the Prince of Wales , which developed in the final years of Henry IV ' s reign , York apparently sided with the King . In 1412 he was again in France , in the company of the King ' s second son , Thomas , assisting the Armagnac party against the Burgundians . Reign of Henry V . Henry IV died on 20 March 1413 . York may have returned to England for a brief time after the King ' s death , but by June 1413 he was preparing to campaign in Aquitaine . In August he was in Paris , negotiating for a marriage between the new King , Henry V , and Catherine of Valois , but was back in England in October , and active in diplomatic negotiations in the final months prior to Henry V ' s invasion of France in 1415 . A few days before the invasion of France , King Henry uncovered the Southampton Plot and the participation in it of York ' s younger brother , Richard of Conisburgh , Earl of Cambridge , for which the younger brother was beheaded on 5 August 1415 . York himself was not implicated in the conspiracy , and he departed with the army for France . He was at the siege of Harfleur , where he made his will on 17 August 1415 , then he commanded the van on the army ' s march through northern France . He commanded the right wing at the Battle of Agincourt on 25 October 1415 , during which he became the highest - ranking English casualty . His death has been variously attributed to a head wound and to being ' smouldered to death ' by ' much heat and pressing ' . York was buried in the Church of St Mary and All Saints , Fotheringhay , where he had earlier established a college for a master and twelve chaplains . The monument now in the church was erected during the reign of Queen Elizabeth . Paradoxically , upon York ' s death the dukedom was inherited by his nephew , Richard Plantagenet , the son of the Southampton coup plotter who had been beheaded a mere two months earlier . Marriages . At the age of eight , York had been taken to Lisbon by his father and betrothed to Beatrice , the daughter of King Ferdinand of Portugal , on 29 August 1381 as part of an alliance of England and Portugal against Castile , but after a rapprochement between Portugal and Castile the marriage was annulled by papal dispensation , and Beatrice married King John I of Castile . Later , King Richard II suggested several possible brides for York , including Joan , sister of the King ' s wife , Isabella of Valois . Before 7 October 1398 York had married Philippa Mohun , third daughter of John Mohun , 2nd Lord Mohun ( c . 1320 – 15 September 1375 ) , and Joan Burghersh ( d . 4 October 1404 ) , daughter of Bartholomew de Burghersh ( c . 1304 – 3 August 1355 ) , 3rd Baron Burghersh , whose mother was Maud de Mortimer . Philippa brought little to her husband , her mother , Joan , having sold the Mohun estates in 1376 . Moreover Philippa was apparently some 20 years older than York , and had had no issue by her two previous husbands , Walter Fitzwalter ( d . 26 September 1386 ) , 3rd Baron Fitzwalter , and Sir John Golafre ( d . 18 November 1396 ) . They had no issue . Philippa died on 17 July 1431 and was buried in Westminster Abbey . Master of Game . York was Henry IV ' s Master of the Hart Hounds . Between 1406 and 1413 he translated and dedicated to the Prince of Wales the " Livre de Chasse " of Gaston III , Count of Foix , one of the most famous of the hunting treatises of the Middle Ages , to which he added five chapters of his own , the English version being known as " The Master of Game " . Arms . As a grandson of the sovereign in the male line Edward of Langley bore the arms of the kingdom , differenced by a " label argent 3 - point , per pale Castile and Leon " . In 1402 he inherited his father ' s arms , which were those of the kingdom differentiated by a " label argent of three points , each bearing three torteaux gules " . Shakespeare and Edward of Langley , 2nd Duke of York . As Duke of Aumerle , Edward of Langley is a major character in William Shakespeare ' s " Richard II " . His death at Agincourt ( as Duke of York ) is portrayed in Shakespeare ' s " Henry V " .
