All the early promise evaporated. His vow to be merciful was falsified almost immediately when he (probably) gave the order to ensure that Richard was killed in imprisonment (possibly starving him to death). Two harvest failures and an inability to be good with money meant that his manifesto commitment not to impose peacetime taxes plunged him into debt. Scotland, Wales and France all fought against him. There were many rebellions at home (including eight assassination attempts) culminating in the Battle of Shrewsbury when Henry decisively defeated and killed Harry Hotspur. Even peace left him at the mercy of a hostile and penny-pinching parliament. Finally some dreadful skin disease left him crippled and dying, dead before he reached fifty.
Mostly uncommemorated (Mortimer claims that his only statue is in Shrewsbury's Battlefield church) Henry started the tradition of giving to the poor on Maundy Thursday (his birthday) an amount proportional to his age. He owned an early (perhaps the first) portable clock (p93). In exile he stayed at Sangatte, outside Paris and in 'Newenham' Priory (I presume this is Newnham Priory which around this time was involved with Mowbray who was the Earl of Norfolk involved in a dispute about a rebellion with Henry which led to his and Henry's exile; Newnham Priory received a grant from Henry IV on 15th February 1409) in Bedfordshire on 7th July 1403 (p265).
Fabulous history of a fascinating king.
