30 May 1920
A demonstration took place in what was then known as Queenstown, now Cobh, in County Cork, where Sinn Fein supporters destroyed a gangway to prevent 1,000 troops from disembarking. The gangway, weighing three tonnes, was lost in the harbour and employees later refused to assist in the unloading of munitions.
There was an attack on the police barracks, petty sessions court and attached buildings in Louth, in Ireland, with twenty men raiding the village. The police barracks had been unused for several months, but the villagers were forced to give the raiders access to their petrol supplies in order for the fires to be started.
