World War I was the biggest conflict in Irish history. More men served and more men died than in all the wars before or since that the Irish fought in. Often forgotten at home and written out of Irish history, the Irish soldiers and their regiments found themselves more honored in foreign fields. From the first shot monument in Mons to the plaque to the Royal Irish Lancers who liberated the town on Armistice Day 1918, Ronan McGreevy takes a tour of the Western Front. He visits those places where the Irish made their mark and left their mark in the monuments, cemeteries, and landscapes of France and Flanders.
