Many believed the Supreme Council were unreliable, since many of them were related to Ormonde or otherwise bound to him. Besides, it was pointed out that the English Civil War had already been decided in the English Parliament's favour and that sending Irish troops to the royalists would be a futile sacrifice. On the other hand, many felt after O'Neill's Ulster army defeated the Scots at the battle of Benburb in June 1646 that the Confederates were in a position to re-conquer all of Ireland. Furthermore, those who opposed the peace were backed, both spiritually and financially, by Rinuccini, who threatened to excommunicate the "peace party". The Supreme Council were arrested and the General Assembly voted to reject the deal.
