Hart took part in the bank robberies at Euroa and Jerilderie. At Euroa he met an old school friend of his, Francis 'Fanny' Shaw (sometimes known as Maggie Shaw) and through her, the police found out his name. Hart also stole a watch from Robert Scott, the bank manager. When a bank worker, Bob Booth, asked him for something to remember the visit by, Hart gave him a lead bullet carved with the letter 'H'.
