In return for the concessions that were made Irish troops would be sent to England to fight for the royalists in the English Civil War. However, the terms agreed were not acceptable to either the Catholic clergy, the Irish military commanders – notably Owen Roe O'Neill and Thomas Preston – or the majority of the General Assembly. Nor was the papal nuncio Rinuccini party to the treaty, which left untouched the objects of his mission; he had induced nine of the Irish bishops to sign a protest against any arrangement with Ormonde or the king that would not guarantee the maintenance of the Catholic religion.
