William Redmond ( 1886 – 1932 ) William Archer Redmond DSO ( 1886 – 17 April 1932 ) was an Irish nationalist politician . He served as an MP in the House of Commons of the United Kingdom of Great Britain and Ireland as well as a Teachta Dála ( TD ) of Dáil Éireann . He was one of the few people to have served in both the House of Commons and in the Oireachtas . During World War I served as officer with an Irish regiment on the Western Front . He was the son of John Redmond the leader of the Irish Parliamentary Party from 1900 to 1918 , and was one of a dynasty of Liberal and Irish Nationalist politicians who are commemorated in Redmond Square in Wexford town . Early career . Redmond was educated at Clongowes Wood College and Trinity College , Dublin . He was elected as MP for Tyrone East at the December 1910 general election and supported the passing of the 1914 Home Rule Act . When his father called for support for the British and Allied war effort in World War I , Redmond joined with the National Volunteers in the New British Army and served on the Western Front for the duration of the war , first in the Royal Dublin Fusiliers and then in the Irish Guards , rose to the rank of captain and was awarded the DSO . His fellow MP and uncle Willie Redmond , John ' s brother , also joined up and was killed in 1917 . Three other Irish MPs also served , J . L . Esmonde , Stephen Gwynn , D . D . Sheehan and former MP Tom Kettle . When his father died in March 1918 , William Archer Redmond resigned his Tyrone seat and successfully defended his father ' s seat of Waterford . Famously he campaigned in his army uniform and wearing a black armband . His victory ended a run of Sinn Féin victories at by - elections and gave a big , albeit temporary , boost to the morale of supporters of the Irish Parliamentary Party . He did not take part in the First Dáil . In the general election of December 1918 , he was re - elected for Waterford City , becoming one of only two Irish Parliamentary Party MPs outside the six counties of Northern Ireland , and he spoke out strongly in the House of Commons against British military policy in Ireland during the Irish War of Independence . Into the Dáil . Following independence , Redmond was elected as an Independent Nationalist deputy and member of the 4th Dáil for Waterford at the 1923 Irish general election . In 1926 , he co - founded the National League Party , appealing to former supporters of the Irish Parliamentary Party , ex - servicemen , and others , including Unionists , alienated by the policies of the Cumann na nGaedheal government . The new party did quite well , winning eight seats at the June 1927 general election . However Redmond alarmed his supporters by entering into a voting pact with the Labour Party and Fianna Fáil to bring down the Cumann na nGaedheal government , and replace it with a minority Labour Party – National League administration supported from outside by Fianna Fáil . The attempt failed and in the ensuing general election in September 1927 , the party won only one seat in addition to Redmond ' s own . The following year the National League was dissolved and in 1931 Redmond joined Cumann na nGaedheal . He died in 1932 and was succeeded as Cumann na nGaedheal deputy for Waterford by his wife , Bridget Redmond .
