On the 29th of June, Lieutenant Tyrrell having received information that a large body of Rebels had stationed themselves upon a hill near his dwelling-house at Kilreiny, and had committed various robberies in the course of the preceding night, he went to Kinnegad to solicit a reinforcement and sent an express to Edendery for a force to co-operate with him. The Kinnegad Yeomen Cavalry, under Lieutenant Houghton, and a small party of the Northumberland Fencibles immediately marched with Lieutenant Tyrrell to Clonard, and from thence being joined by his own Corps, he proceeded to _Fox's hill_, where the Rebels were posted to the amount of 600.--The attack was began by the Clonard Supplementaries, who displayed great steadiness upon this occasion; the Kinnegad Corps and the Northumberlands supported the attack with great zeal, and the Edenderry force consisting of a detatchment of the Limerick, Lieutenant Colonel Gough, the Coolestown Cavalry, Captain Wakely and the Canal Legion, Lieutenant Williams, having fallen upon the Rebels from the opposite side, they were routed with considerable slaughter. Their commander, one _Casey_, his brother and another Leader were killed in this action, and their bodies brought to Edenderry, where they were exposed for several days. _JUNCTION OF THE WEXFORD AND KILDARE REBELS._ It might have been hoped, that these successes would have established tranquility in this neighbourhood, and probably such effects would have followed the military exertions, were it not for the irruption of a large column of Wexford Rebels into Kildare, under the command of Colonel _Perry_ who being immediately joined by Colonel _Aylmer_, commanding the Rebel Camp at Prosperous, was prevailed upon to abandon his intention of penetrating into the North, and to adopt a plan suggested by _Aylmer_, of attacking Clonard, pushing on from thence by Kilbeggan to the Shannon and surprising Athlone. In pursuance of this plan, the Rebel Forces amounting to 4000 men made a movement towards Clonard. _BATTLE OF CLONARD._
