The Four Courts On Fire, Civil War. (1922).

Republican forces opposed to the Anglo-Irish Treaty of 1921 had taken over The Four Courts on Inns Quay in central Dublin. The newly formed Irish Free State was put under pressure by the British government to act as they threatened to act themselves and suspend the evacuation of British troops from Ireland if the rebels were not rounded up. Reluctantly in the early hours of the 28th June 1922, as head of the Irish Free State Army, Michael Collins had The Four Courts surrounded and attacked the building with heavy artillery. This would signal the start of the Civil War.
