After Llywelyn the Great died in 1240, his son Dafydd ap Llywelyn faced a determined English campaign by Henry III aimed at clawing back Welsh gains. Henry advanced to north Wales in 1241 and Dafydd was forced to submit, surrendering his half-brother Gruffudd as a hostage. Gruffudd died attempting to escape from the Tower of London in 1244 — falling when his makeshift rope of sheets broke. His death made his son Llywelyn ap Gruffudd more determined to resist English pressure.
