This took place at the end of 1641 and the beginning of 1642, and the other forces of the country were organized about the same time. The lines of difference between the Anglican and Catholic parties were at this time very lightly drawn, and the Norman lords found themselves able to co-operate with the Catholic bishops in forming a General Assembly at Kells, which straightway set itself to frame a Constitution for the country.
The Norman lords had meanwhile assembled and organized their retainers, so that there were now three armies in Ireland: the garrison of the Scottish settlers under Monroe, strongly in sympathy with the Puritans; the tribal army under Owen Roe O'Neill; and the army of the Norman lords. The General Assembly outlined a system of parliamentary representation in which the Lords and Commons were to form a single House, the latter, two hundred and twenty-six in number, representing all the important cities and towns. A supreme Cabinet was to be formed, composed of six members for each of the four provinces, twenty-four in all, who might be lords spiritual or temporal, or commoners, according to the choice of the Parliament. This Cabinet, thus selected from the whole Parliament, was the responsible executive of the country; and under the Supreme Council a series of Provincial Councils and County Councils were to be formed along the same lines.
This plan was adopted at a general meeting of all the influential forces of the country, which assembled in May at Kilkenny, where many Parliaments had sat during the fourteenth and fifteenth centuries. Writs were issued for elections under the new Constitution, and the date of the first assembly of the new Parliament was fixed for October. The new national body enjoyed abundant revenues, and no small state marked its deliberations in Kilkenny. We read of an endless series of illuminations, receptions, banquets and balls,--the whole of the Norman nobility of Leinster lavishing their great wealth in magnificent display. The Supreme Council journeyed in state from Kilkenny to Wexford, from Wexford to Waterford, from Waterford to Limerick and Galway, surrounded by hundreds of horsemen with drawn swords, and accompanied by an army of officials. We hear of "civil and military representations of comedies and stage plays, feasts and banquets, and palate-enticing dishes."
The General Assembly, duly elected, finally met on October 23, 1642, at Kilkenny. On the same day was fought the battle of Edgehill, between the king of England and the forces of the English Parliament. This battle was the signal for division of counsels in the new Assembly. The Norman lords of Leinster, who stood on the ground of feudalism, and lived under the shadow of royal authority, were strongly drawn to take the side of the king against the English Parliament, and overtures of negotiation were made, which came near gaining a recognition and legalization of the General Assembly by the English Crown.
While the leaders at Kilkenny were being drawn towards the royalists of England, Owen Roe O'Neill was successfully holding Ulster against the Puritan forces under Monroe and Leslie, with their headquarters at Carrickfergus. Thus matters went on till the autumn of 1643, when we find him inflicting a serious defeat on the English army under Monk and Moore at Portlester in Meath, in which Moore was killed and his forces driven back within the walls of Drogheda.
The General Assembly continued to exercise sovreign authority at Kilkenny, collecting revenues, maintaining courts of justice in the provinces, and keeping several armies in the field, most effective of which was undoubtedly that of Owen Roe O'Neill. We find matters still in this condition three years later, in May, 1646, when Monroe and the Scottish forces prepared to inaugurate an offensive campaign from their base at Carrickfergus. General Robert Monroe had about seven thousand men at Carrickfergus; his brother George had five hundred at Coleraine; while there was a Scottish army at Derry, numbering about two thousand men. It was decided to converge these three forces on Clones, in Monaghan, and thence to proceed southwards against the government of the General Assembly, then centered at Limerick. Clones was sixty miles from Derry, and rather more from Coleraine and Carrickfergus, the two other points of departure.
Owen Roe O'Neill was then at Cavan, fourteen miles south of Clones, with five thousand foot and five hundred horse, all "good, hopeful men," to use his own words. General Robert Monroe, starting from Carrickfergus, and marching by Lisburn and Armagh, expected to reach Glasslough, some sixteen miles from Clones, on June 5th. By a forced march from Cavan, Owen Roe O'Neill reached Glasslough a day earlier, and marching along the northern Blackwater, pitched his camp on the north bank of the river. Here he was directly in the line between the two Monroes, who could only join their forces after dislodging him; and Robert Monroe, who by that time had reached Armagh, saw that it would be necessary to give battle without delay if the much smaller forces from the north were not to be cut off.
Robert Monroe began a movement northwards towards Owen Roe's position at dawn on June 5th, and presently reached the Blackwater, to find himself face to face with Owen Roe's army across the river. The two forces kept parallel with each other for some time, till Robert Monroe finally forded the Blackwater at Caledon, Owen Roe then retiring in the direction of the current, which here flows north. Owen Roe, in his movement of withdrawal, brought his army through a narrow pass, which he left in charge of one of his best infantry regiments, with orders to hold it only so long as the enemy could be safely harassed, meanwhile carrying his main body back to the hill of Knocknacloy, the position he had chosen from the first for the battle, and to gain which he had up to this time been manoeuvering.
