John's illness grew worse and by the time he reached Newark Castle he was unable to travel any farther; John died on the night of 18 October. Numerous – probably fictitious – accounts circulated soon after his death that he had been killed by poisoned ale, poisoned plums or a "surfeit of peaches". His body was escorted south by a company of mercenaries and he was buried in Worcester Cathedral in front of the altar of St Wulfstan. A new sarcophagus with an effigy was made for him in 1232, in which his remains now rest.

When did John die?
