Parliament was not again called together till the month of October, 1781; the interval being busily occupied on both sides with endeavours to create and sustain a party. Soon after the meeting, Mr. Grattan, seconded by Mr. Flood, moved for a limitation of the Mutiny Bill, which was lost; a little later, Mr. Flood himself introduced a somewhat similar motion, which was also outvoted two to one; and again, during the session, Mr. Yelverton, having abandoned his promised motion against Poyning's law, on news of Lord Cornwallis's surrender reaching Dublin, Flood took it up, moved it, and was defeated. A further measure of relief for Roman Catholics, introduced by Mr. Gardiner, author of the act of 1778, and warmly supported by Grattan, was resisted by Flood in the one House, and Lord Charlemont in the other. It miscarried, and left another deposit of disagreement between the actual and the former leader of the Patriot party.
Still no open rupture had taken place between the two Patriot orators. When the convention of the volunteers was called at Dungannon for the 15th of February, 1782, they consulted at Charlemont House as to the resolutions to be passed. They were agreed on the constitutional question; Grattan, of his own generous free will, added the resolution in favour of emancipation. Two hundred and forty-two delegates, representing 143 corps, unanimously adopted the resolutions so drafted, as their own, and, from the old head-quarters of Hugh O'Neil, sent forth anew an unequivocal demand for civil and religious liberty. The example of Ulster soon spread through Ireland. A meeting of the Leinster volunteers, Mr. Flood in the chair, echoed it from Dublin; the Munster corps endorsed it unanimously at Cork; Lord Clanrickarde summoned together those of the western counties at Portumna—an historic spot, suggestive of striking associations. Strengthened by these demonstrations of public opinion, Mr. Grattan brought forward, on the 22nd of February, his motion declaratory of the rights of Ireland. An amendment in favour of a six months' postponement of the question was carried; but on the 16th of April, just two years from his first effort on the subject (the administration of Lord North having fallen in the meantime), the orator had the satisfaction of carrying his address declaratory of Irish legislative independence. It was on this occasion that he exclaimed: "I found Ireland on her knees; I watched over her with a paternal solicitude; I have traced her progress from injury to arms, and from arms to liberty. Spirit of Swift! Spirit of Molyneux! your genius has prevailed! Ireland is now a nation! in that new character I hail her! and bowing to her august presence, I say, _Esto perpetua!_"
