At about three in the morning of 26 June 1830 at Windsor Castle, George awoke and passed a bowel movement – "a large evacuation mix'd with blood". He then sent for Halford, allegedly calling to his servants "Sir Henry! Sir Henry! Fetch him; this is death!" Accounts of George's final moments and last words vary. According to Halford, following his arrival and that of Sir William Knighton, the King's "lips grew livid, and he dropped his head on the page's shoulder ... I was up the stairs in five minutes, and he died but eight minutes afterwards." Other accounts state the King placed his hands on his stomach and said "Surely, this must be death", or that he called out "Good God, what is this?", clasped his page's hand, said "my boy, this is death", and died. George died at 3:15 a.m. An autopsy conducted by his physicians revealed George had died from upper gastrointestinal bleeding resulting from the rupture of a blood vessel in his stomach. A large tumour "the size of an orange" was found attached to his bladder; his heart was enlarged, had heavily calcified valves and was surrounded by a large fat deposit.
