4 June 1920
Cappawhite RIC Barracks in Co. Tipperary was attacked by the IRA. The roof of the adjoining Courthouse was also set on fire during the attack which lasted for three hours before the Volunteers withdrew. They didn't capture any arms or ammunition the only casualty was one RIC constable wounded.
Winston Churchill, answering a question in the House of Commons, confirmed there were 40 tanks and 28 RAF planes in Ireland to deal with Sinn Féin. The British press were reporting that senior Cabinet members were keen to get the IRA on the streets in open warfare where the tanks and machine guns would get their chance to mow them down. Which rather nicely echoes @Mike Barton 's comment a few days back.
