It is likely that this funeral was for the fourteen British secret agents who were assassinated by the IRA. In retaliation 'Black and Tans' opened fire on the crowd at a Gaelic football match at Croke Park, killing 12 people. The event became known as Bloody Sunday. Since this film is dated 1/11/1921 it is not a fresh report on Bloody Sunday (which was on 21 November 1920).
