On February 21st, 1642, Colonel Monk landed in Dublin at the head of the Lord-General's regiment of foot. It was a splendid body of men, two thousand strong and officered by the flower of the disbanded army of the north. And with him was Sir Richard Grenville, commanding four hundred of Leicester's new regiment of horse. Over the scenes which followed there is no need to linger. In fire and blood the wretched Irish had to do penance for the outburst of savagery to which they had been goaded by Strafford's imperious rule. The most important operation of the campaign of 1642 was the expedition for the relief of the English settlements in Kildare and Queen's County. With two thousand five hundred foot under Monk, five hundred horse under Lucas, Coote, and Grenville, and six guns, Ormonde left Dublin on April 2nd, and by the 9th had successfully relieved Athy, Maryborough, and some smaller settlements. The work was accomplished with all the horrible accompaniments which characterised Irish warfare. "In our march thither," wrote an officer in Monk's regiment, "we fired above two hundred villages. The horse that marched on our flanks fired all within five or six miles of the body of the army; and those places that we marched through, they that had the rear of the army always burned. Hitherto we met not with any enemy to oppose, yet not a mile nor a place that we marched by, that the dead bodies of the rebels did not witness our passage." But the most difficult part of the enterprise yet remained. Some thirty miles beyond the river Nore, in a country swarming with rebels, lay several garrisons yet unrelieved. Ormonde's provisions were running so short that to reach them by a regular operation was impossible; but sooner than abandon them Grenville, Lucas, and Coote undertook to make a dash to their aid with the cavalry, while Monk covered the retreat. On the morning of Saturday the 10th, in the dead of night, the horse sallied from Maryborough, and succeeded in passing the river unobserved. The Irish at once took the alarm, and seized the only two fords by which they could return. That at Portnahinch they barred by an intrenchment, and leaving the other open they laid a strong ambush along the dangerous causeway by which it was approached. There, certain of their prey, they quietly waited to wreak a terrible vengeance on Grenville's ruthless troopers. On Monk rested the only chance of escape. Early on Monday morning, with a party of six hundred musketeers, he attacked a neighbouring castle, which belonged to one of the rebel leaders, hoping to draw to its relief the forces which held the fords; but not a man would they stir. In desperation he determined to force the pass at Portnahinch, but on reaching it he found the river so swollen that it was impassable for foot. The last hope seemed gone, but Monk was not to be beaten. Seizing every point of vantage on his own bank, he placed his musketeers with
