Sir Henry Percy (20 May 1364 – 21 July 1403), nicknamed Hotspur, was an English knight who fought in several campaigns against the Scots in the northern border and against the French during the Hundred Years' War. The nickname "Hotspur" was given to him by the Scots as a tribute to his speed in advance and readiness to attack. The heir to a leading noble family in northern England, Hotspur was one of the earliest and prime movers behind the deposition of King Richard II in favour of Henry Bolingbroke in 1399. He later fell out with the new regime and rebelled, and was slain at the Battle of Shrewsbury in 1403 at the height of his fame. Career Henry Percy was born 20 May 1364 at either Alnwick Castle or Warkworth Castle in Northumberland, the eldest son of Henry Percy, 1st Earl of Northumberland, and Margaret Neville, daughter of Ralph de Neville, 2nd Lord Neville of Raby, and Alice de Audley. He was knighted by King Edward III in April 1377, together with the future Kings Richard II and Henry IV. In 1380, he was in Ireland with the Earl of March, and in 1383, he travelled in Prussia. He was appointed warden of the east march either on 30 July 1384 or in May 1385, and in 1385 accompanied Richard II on an expedition into Scotland. "As a tribute to his speed in advance and readiness to attack" on the Scottish borders, the Scots bestowed on him the name 'Haatspore'. In April 1386, he was sent to France to reinforce the garrison at Calais and led raids into Picardy. Between August and October 1387, he was in command of a naval force in an attempt to relieve the siege of Brest. In appreciation of these military endeavours, at the age of 24 he was made a Knight of the Garter in 1388. Reappointed as warden of the east march, he commanded the English forces against James Douglas, 2nd Earl of Douglas, at the Battle of Otterburn on 10 August 1388, where he was captured, but soon ransomed for a fee of 7000 marks. During the next few years Percy's reputation continued to grow. Although not 30, he was sent on a diplomatic mission to Cyprus in June 1393 and appointed Lieutenant of the Duchy of Aquitaine (1394–98) on behalf of John of Gaunt, Duke of Aquitaine. He returned
