On the 31st of October 1479, the Duke of Clarence, who was the younger brother of Edward IV, was buried at Tewkesbury Abbey. He was said to have met a unfortunate end by drowning in a vat of Malmsey wine when he was 28.
If you look further into his death, the Duke of Clarence was said to have been a paranoid alcoholic, who was said to have been a participant in a plot against the king. He was privately executed at the Tower of London for treason. He was said to have to asked to be killed by drowning in a vat of his favourite tipple but this has never been verified.
