The Irish Citizen Army existed from 1913–1947 and one of its creators was Jack White from Ulster, son of General George White. On Easter Monday, 24 April 1916, 220 of the group (including 28 women) took part in the Easter Rising. Most of the rifles and ammunition used in the Rising had been imported from Germany in July 1914 by Erskine Childers on his yacht "Asgard" along with Conor O'Brien, Alice Stopford Green, Mary Spring Rice, Darrell Figgis and the former Quaker Bulmer Hobson. The rest of the rifles were shipped by Sir Thomas Myles, at the suggestion of the barrister James Meredith, and were landed at Kilcoole. In 1913 Hobson had sworn Patrick Pearse into the IRB; Pearse was one of leaders of the Rising. A prominent signatory to the Anglo-Irish Treaty in late 1921 that followed the Anglo-Irish war was Robert Barton, a cousin of Childers.
