Seven Republican fighters, all from County Kildare, are executed in the Glasshouse in the Curragh Camp on December 19, 1922. The Glasshouse is a small stone and brick military prison where the military usually houses their own prisoners. It consists of two floors enclosed within a twelve foot high walled enclosure with cells for 64 prisoners. During the Irish Civil War, and afterwards, it is used as a punishment block for Republican prisoners.

The seven, Patrick Bagnall, Patrick Mangan, Joseph Johnston, Bryan Moore, Patrick Nolan, Stephen White and James O’ Connor, are all veteran Irish Republican Army (IRA) men and belong to a column of ten which operates against railways, goods trains and some shops in the vicinity of Kildare. Five of them are involved in the derailment of engines at Cherryville on December 11 when they make a serious attempt to dislocate the whole railway service on the Great Southern and Western Railway. Two engines are taken out of a shed at Kildare and sent down the line by Cherryville. One engine runs out of steam and does no harm, while the other overturns and blocks the line for a considerable time.

The column is also responsible for an ambush on National troops at the Curragh Siding on November 23 when a large party of troops are returning to Dublin after escorting prisoners to the Curragh Camp. On their return journey the troops are fired on at the Curragh Siding and two are wounded. In the confusion a policeman is accidentally shot by a National soldier.

The seven, along with Commandant Thomas Behan, are found in a dug-out at Mooresbridge, on the edge of the Curragh, on the night of December 13. They are under the command of Commandant Bryan Moore, a veteran IRA officer, and comprise a section of the 6th Battalion Column. They are armed with rifles bought from a soldier stationed in Naas Barracks.

When they surrender, Behan is struck with a rifle butt, breaking his arm. When the captives are ordered into the back of a truck he cannot climb aboard because of his arm. He is struck again on the head with a rifle butt and dies at the scene.

The remaining seven men are charged before a Military Committee with being in possession, without proper authority, of ten rifles, 200 rounds of ammunition, four bomb detonators and one exploder. They are found guilty and sentenced to death. Father Donnelly, chaplain to the troops, administers to the seven volunteers before their executions. They are executed one by one by firing squad on the morning of December 19 and are buried in the yard adjacent to the Glasshouse.
