On 29 July 1848, O'Brien and other Young Irelanders led landlords and tenants in a rising in three counties, with an almost bloodless battle against police at Ballingarry, County Tipperary. In O'Brien's subsequent trial, the jury found him guilty of high treason. He was sentenced to be hanged, drawn, and quartered. Petitions for clemency were signed by 70,000 people in Ireland and 10,000 people in England.
