Hales was stroke oar on the Jolly boat during the cutting out of Papillon and was left behind as he was left in the jolly boat when Hornblower's crew boarded as he said he was feeling 'queer'. Hales was having a 'fit' as Hornblower's crew was approaching the Papillon, requiring Hornblower to render him unconscious. Seaman Wells was to be the boatkeeper during boarding, but, had to take Hales place. Hales was left behind when Papillon was cut out.
