My thanks to Tim Pat Coogan, for clarifying certain historical aspects relating to the siege of the Four Courts, Dublin.
Authors, Tim Pat Coogan and George Morrison, co-wrote the best selling book - "The Irish Civil War"
On the morning of the 30th June, 1922, Free State Troops, manning the 18-pounder field gun at the intersection of Winetavern St. and Merchants' Quay, observe the massive explosion of the main munitions dump in the cellars beneath the Public Records Office in the Four Courts, Dublin.
I was given invaluable assistance with my research on this painting from the Military Archives Division of the Irish Army; I thank Comdt. Victor Laing in particular.
