Despite efforts to appear masculine, witness reports comment on Barry's effeminacy and on a somewhat contradictory reputation – Barry had a reputation for being tactless, impatient, argumentative and opinionated, but was also considered to have had a good bedside manner and famous professional skill. Barry's temper and bravado led to a famous pistol duel with Captain Josias Cloete of the 21st Light Dragoons. Barry's aim was better, the bullet striking Cloete's shako military cap and removing its peak, which dissipated its force.
