Despite the Free State force's success in taking the Four Courts, fighting continued in Dublin until 5 July. On the 29th anti-Treaty IRA units from the Dublin Brigade led by Oscar Traynor had occupied O'Connell Street, part of Parnell Square, York Street and some of other locations to try to distract Free State attention from their attack on the Four Courts. Not all the IRA units in the capital were prepared to fight against the new Irish government, however, and their numbers were probably about 500 throughout the city. Their numbers were supplemented by about 150 Citizen Army men and women who brought with them arms and ammunition dumped since the insurrection of Easter 1916.
