 The motion was defeated, but the IRA split into two factions opposed to the government, one conciliatory, led by Liam Lynch, Sean Moylan, and Liam Deasy, and the other less moderate, led by Tom Barry and Joe McKelvey.On 22 June 1922 Sir Henry Wilson was assassinated in London by two IRA men, both former British soldiers, Reginald Dunne and Joseph O'Sullivan.It is now considered by some that this was done on the orders of Michael Collins, who had been a close friend of Dunne in the London IRB.
