The Silver Tassie is a four-act Expressionist play about the First World War, written between 1927 and 1928 by the Irish playwright Seán O'Casey.
"[2] An antiwar play in four acts, focusing on Harry Heegan, a soldier who goes to war as if going to a football match.
The play's study of Harry’s loss of many of his life’s hopes during and after the war marks it as unusual.
Its Irish première was on 12 August 1935 at the Abbey Theatre, directed by Arthur Shields, though it ran for only five performances.
[4] The first major production in England was by the RSC at the Aldwych Theatre, London, directed by David Jones, which opened on 10 September 1969 with Richard Moore as Harry Heegan.
