While the fighting in the south was largely ended by the Truce on 11 July 1921, in the north killings continued and actually escalated until the summer of 1922. In Belfast, 16 people were killed in the two days after the truce alone. The violence in the city took place in bursts, as attacks on both Catholics and Protestants were rapidly followed by reprisals on the other community. In this way, 20 people died in street fighting and assassinations in north and west Belfast over 29 August to 1 September 1921 and another 30 from 21 to 25 November. Loyalists had by this time taken to firing and throwing bombs randomly into Catholic areas and the IRA responded by bombing trams which took Protestant workers to their places of employment.
