On 12 March 1868, the Prince attended the Sailor's Picnic at
Clontarf, Sydney. O'Farrell came up behind the Prince and fired a revolver into his back. The assassin was immediately tackled by William Vial, a local coach-maker and O'Farrell was severely beaten and nearly lynched by the mob before police arrested him. The wound was serious, but not fatal.
