defeated by six votes to five. After the death of Lynch in a Free State attack on 10 April, the anti-treaty campaign was halted on 30 April, then called off when Frank Aiken issued an order on 24 May to "dump arms". One author claims that Barry tried to act as intermediary with the pro-Treaty Irish Republican Brotherhood to end the war and for a time had a letter from the Free State authorities granting him 'immunity from arrest'. This caused him to fall out with other members of the IRA Army Council. For his part, Barry stated that rumours, some spread by Republicans, about his negotiating for peace or compromise with the Free State were "absolutely false". Nevertheless, the Free State government never formally acknowledged the end of the civil war marked by the republicans' ceasefire and dump arms order. Barry had to remain on the run until a general amnesty was declared in November 1924. The Third Cork IRA Brigade, of which Barry commanded the Active Service Unit or flying column, lost 34 men killed in the war against the British and another 21 anti-Treatyites killed in the civil war. This made a total of 55, excluding pro-Treaty volunteers who died in the civil war but whom Barry did not record in his memoir. Subsequent IRA career According to historian Brian Hanley, Tom Barry left the IRA shortly after the Executive had narrowly defeated his proposal (of March 1923) to hand over its arms to prevent further bloodshed between nationalists. In his letter of 11 July 1923 to the Army Executive, Barry resigned as a member of that body, the Army Council and an IRA officer. He offered his services if, at some future date, arms should be taken up again in the struggle to make Ireland an independent country. Barry's biographer Meda Ryan disputes this evidence, claiming that Barry only resigned from the IRA leadership in 1923, but remained a rank and file member before reassuming a leadership role in 1932. He served as general superintendent of Cork Harbour Commission from 1927 to 1965. He initially proposed cooperation of the IRA and Fianna Fáil, the party led by erstwhile republican leader Éamon de Valera, especially against the Blueshirts, a militant movement born out of Pro-treaty civil war veterans. However, De Valera banned both the IRA and the Blueshirts, and Barry was imprisoned from May to December 1934
