He was educated at CBS Tralee and Blackrock College, Dublin, where he began a lifelong friendship with Éamon de Valera.
He was involved in the attempt to land arms from the Aud in April 1916, he was arrested after the Easter Rising and interned at various prisons until the general release of December 1916.

During the Irish Civil War, he was a member of anti-treaty forces, and took part in the defence of Tralee and later assumed command of a Dingle column.
