 Collins, although less diplomatic than Griffith or de Valera, had no less penetrating comprehension of political issues.He complained that he was being manipulated into "doing Churchill's dirty work", in a potential civil war with his own former troops.Negotiations to prevent civil war resulted in, among others, "The Army Document" published in May 1922 which was signed by an equal number of pro- and anti-Treaty IRA officers including Collins, Dan Breen, and Gearóid O'Sullivan.
