John Holland, 2nd Duke of Exeter

John Holland, 2nd Duke of Exeter, 2nd Earl of Huntingdon was an English nobleman and military commander during the Hundred Years' War. His father, the 1st Duke of Exeter, was a maternal half-brother to Richard II of England, and was executed after King Richard's deposition. The Holland family estates and titles were forfeited, but John was able to recover them by dedicating his career to royal service. Holland rendered great assistance to his cousin Henry V in his conquest of France, fighting both on land and on the sea. He was marshal and admiral of England and governor of Aquitaine under Henry VI.
