Many of the County Kildare rebels returned to their homes while many of the Meath men were dissuaded from joining the rebellion by the defeat and due to much of their existing stocks of ammunition being wasted in the battle.

After the rebel defeat at the battle of White Heaps/Ballygullen, the last major engagement in County Wexford,[5] the surviving rebel forces moved into County Kildare on the 9th of July and sought to spread the rebellion on their way north to Ulster under the command of Anthony Perry, Garret and William Byrne, Edward Fitzgerald, and a local priest named Kearns they reinforced the army formerly under the command of Michael Reynolds who died at the Battle of Naas in late June.

Clonard was chosen as it was believed there was a store of arms at the garrison and to also to avoid the thousands of British troops who were combing Kildare for them.

On the morning of Wednesday 11 July, Richard Allen nephew to Lt. Thomas Tyrrell and a member of Clonard Cavalry rode into the courtyard of Tyrrell House around 11 o'clock and reported that he had been pursued by a piquet guard of rebels he managed to evade the force and reported that he was sure a considerable force was approaching.

As the approaching force was expected along the Dublin road six members of the corps including Richard, Thomas jnr and George took position in an old turret at the very edge of the garden by the road to the bridge, some other outposts were established around the property and ammunition provided, the bulk of the force including Lt. Tyrrell setting up in the main house.

[10] Richard Allen, Thomas Tyrrell Jnr and 2 others jumped 20 feet from one of the upper windows into the hay yard and made their way to the main house safely avoiding the rebels.

The battle had raged for nearly 6 hours now and the rebels continued their attack with no sign of abating when in west was seen loyalist reinforcements approaching.

In the end the loyalists won the hill and the day with the remaining rebels outside the walls still under constant fire from the house and the reinforcements retreating in defeat.
