 In the Summer of 1415, during the Hundred Years' War, the army of Henry V of England camped on Agincourt Field on the Bossington estate on its way to embark for northern France and the campaign which ended with the Battle of Agincourt.John of Gaunt, 1st Duke of Lancaster, a son of Edward III from whom the Plantagenet House of Lancaster was descended, had a palace or hunting lodge in the neighbouring village of King's Somborne and a medieval deer park in the valley here in the fourteenth century.Some of the remains of the deer park's boundary embankments (or pale) can still be seen near Black Lake Farm as you cross the valley on foot on the Clarendon Way.
