- Gascon contingent (c. 1251 – February 1311)
February 1311), Baron of Pontefract, Lord of Bowland, Baron of Halton and hereditary Constable of Chester, was an English nobleman and confidant of King Edward I. He served Edward in Wales, France, and Scotland, both as a soldier and a diplomat. Through his mother he was a great grandson of Amadeus IV, Count of Savoy. He is the addressee, or joint composer, of a poem (a tenson) by Walter of Bibbesworth about crusading, La pleinte par entre missire Henry de Lacy et sire Wauter de Bybelesworthe pur la croiserie en la terre seinte.
He became Chief Councillor to King Edward I, son and successor of Henry III. While the king was engaged in military conflicts with the Scots, Henry was appointed Protector of the Realm. Having taken part in the Conquest of Wales in 1282, Henry was granted the Lordship of Denbigh and built Denbigh Castle. In 1296 he went to France with Edmund, Earl of Lancaster (“Edmund Crouchback”), the king’s younger brother, on whose death in that year he succeeded as commander of the English forces in Gascony; he returned to England early in 1298. He was at the Battle of Falkirk in 1298 and at the Siege of Carlaverock Castle in 1300, both in Scotland. The Roll of Carlaverock records his coat of arms in verse as: Or, a lion rampant purpure. In November 1300 he was sent on a mission to Rome to complain to the Pope about injury done by the Scots. He was present at King Edward’s death in July
