A week of street fighting in Dublin ignited the brutal Irish Civil War
In June 1922, the Irish Provisional Government turned artillery on its own former comrades occupying the Four Courts. This week-long urban siege not only claimed dozens of lives and destroyed centuries of irreplaceable state records but also shattered the fragile peace following the Irish War of Independence.
The Battle of Dublin, spanning from 28 June to 5 July 1922, was the opening act of the Irish Civil War. It pitted the new Provisional Government against anti-Treaty IRA militants who had occupied the Four Courts in April, hoping to provoke a renewed conflict with the British to force an all-Ireland Republic. Under intense pressure from Winston Churchill, who viewed the occupation as a breach of the Anglo-Irish Treaty, Michael Collins finally ordered a military response.
The siege was marked by the use of heavy artillery in a dense urban environment, leading to significant civilian casualties. A defining moment occurred on 30 June when a massive explosion destroyed the Irish Public Record Office, obliterating centuries of historical documents. While contemporary propaganda blamed the anti-Treaty forces for booby-trapping the building, modern research suggests the blast was likely an accidental result of fires caused by the shelling reaching stored explosives. The loss was so profound that a modern consortium is now attempting a virtual recreation of the destroyed archives.
By 5 July, the Provisional Government had secured a decisive victory, though the conflict spread across the country. The fighting in Dublin resulted in at least 80 deaths and over 280 injuries. Among the final casualties was Cathal Brugha, who died after a lone stand at the Hammam Hotel. The battle left the Free State in control of the capital, forcing the remaining anti-Treaty forces to retreat toward the Munster region, setting the stage for the wider civil war that would follow throughout the summer of 1922.
