Open conflict erupted on Roches Street in April 1920 between the Royal Welch Fusiliers and the general population, involving bayonets on the one side and stones and bottles on the other. The troops fired indiscriminately, killing a publican and an usherette from the Coliseum Cinema. The British Government organised a new force to quell the population. The Black and Tans, known as "the sweepings of English jails", were formed of ex-servicemen. On the night of 6 March 1921, Limerick's Mayor, George Clancy, and his wife were shot in their home by three Tans.

In Limerick, the first signs of trouble came when the British forces withdrew early in the New Year.

In the event the Brigade split into pro- and anti-Treaty factions, the latter led by Forde. William St. became a battle zone by 7 p.m. on 11 July 1922, when the Free State troops opened fire on the Republican garrison holding the Ordnance Barracks. In the
