The largest single clash came in June, when British troops used artillery to dislodge an IRA unit from the village of Pettigo, killing seven, wounding six and taking four prisoners. This was the last major confrontation between the IRA and British forces in the period 1919–1922.
The cycle of sectarian atrocities against civilians however continued into June 1922. May saw 75 people killed in Belfast and another 30 died there in June. Several thousand Catholics fled the violence and sought refuge in Glasgow and Dublin.
On 17 June, in revenge for the killing of two Catholics by the B-Specials, Frank Aiken's IRA unit shot ten Protestant civilians, killing six in and around Altnaveigh, south Armagh. Three Special Constables were also killed in the shootings.
In June 1922, Garvey met with Edward Young Clarke, the Imperial Wizard pro tempore of the Ku Klux Klan (KKK) at the Klan's offices in Atlanta. Garvey made a number of incendiary speeches in the months leading up to that meeting; in some, he thanked the whites for Jim Crow. Garvey once stated: I regard the Klan, the Anglo-Saxon clubs and White American societies, as far as the Negro is concerned, as better friends of the race than all other groups of hypocritical whites put together. I like honesty and fair play. You may call me a Klansman if you will, but, potentially, every white man is a Klansman as far as the Negro in competition with whites socially, economically and politically is concerned, and there is no use lying. News of Garvey's meeting with the KKK soon spread and it was covered on the front page of many African-American newspapers, causing widespread upset.
