 Passage 3:He was a member of the Irish Volunteers and on the outbreak of the 1916 Easter Rising he walked the 26 kilometres to Dublin to fight in the Rising. He was imprisoned in the mass arrests and deportations that followed, and released in 1917. Like many Rising survivors, he joined Sinn Féin, a small separatist party that was wrongly blamed by the British government for the Easter Rising. In the aftermath of the Rising, survivors led by Éamon de Valera took over the party in the struggle for the establishment of an Irish republic. Ua Buachalla was elected as a Sinn Féin MP for Kildare North at the 1918 general election. He served in the First Dáil (1918–1921), and was re-elected to the Second Dáil in 1921 as a Teachta Dála (TD) for Kildare–Wicklow. He sided with de Valera and opposed the Anglo-Irish Treaty. He fought in the Four Courts in the Civil War. Imprisoned in Dundalk jail, he was released by the Anti-Treaty troops in August 1922. He lost his seat at the 1922 general election, and was an unsuccessful candidate at the 1923 general election.
