It was only after some hesitation that the Ulster Unionist Council decided not to hold aloof from the Convention, as the Sinn Feiners did. Carson accompanied Sir John Lonsdale to Belfast and explained the explicit pledges by Ministers that participation would not commit them to anything, that they would not be bound by any majority vote, and that without their concurrence no legislation was to be founded on any agreement between the other groups in the Convention; he also urged that Ulster could not refuse to do what the Government held would be helpful in the prosecution of the war.
The invitation to nominate five delegates was therefore accepted; and when the membership of the Convention was complete there were nineteen out of ninety-five who could be reckoned as supporters in general of the Ulster point of view. Among them were the Primate, the Moderator of the General Assembly, the Duke of Abercorn, the Marquis of Londonderry, Mr. H.M. Pollock, Chairman of the Belfast Chamber of Commerce, one Labour representative, Mr J. Hanna, and the Lord Mayors of Belfast and Derry. It was agreed that Mr. H.T. Barrie, member for North Derry, should act as chairman and leader of the Ulster group, and he discharged this difficult duty with unfailing tact and ability.
There was some difficulty in finding a suitable Chairman, for no party was willing to accept any strong man opposed to their own views, while an impartial man was not to be found in Ireland. Eventually the choice fell on Sir Horace Plunkett as a gentleman who, if eagerly supported by none, was accepted by each group as preferable to a more formidable opponent. Sir Horace made no pretence of impartiality. Whatever influence he possessed was used as a partisan of the Nationalists. He was not, like the Speaker of the House of Commons, a silent guardian of order; he often harangued the assembly, which, on one occasion at least, he addressed for over an hour; and he issued manifestos, questionnaires, and letters to members, one of which was sharply censured as misleading both by Mr. Barrie and the Bishop of Raphoe.
The procedure adopted was described by the Chairman himself as “unprecedented.” It was not only that, but was unsuitable in the last degree for the purpose in view. When it is borne in mind what that purpose was, it is clear that the only business-like method would have been to invite the Ulster delegates at the outset to formulate their objections to coming under the Home Rule Act of 1914, and then to see whether Mr. Redmond could make any concessions which would persuade Ulster to accept something less than the permanent exclusion of six counties, which had been their minimum hitherto.
