While in Pentridge prison's H division in the late 70's, Read launched a prison war. His gang, dubbed 'The Overcoat Gang', because they wore long coats all year round to conceal their weapons, were involved in several hundred acts of violence against a larger opposing gang during this period. Around this time, Read had a fellow inmate cut both of his ears off in order to be able to leave H division temporarily. Whilst in his early biographies Read claimed this was to avoid an ambush by other inmates, his later works state that he did so to "Win a bet". Several other members of Read's gang also cut off their own ears in a similar fashion after this incident
