The 1923 FAI Cup Final was contested by League of Ireland side Shelbourne of Dublin and Alton United of Belfast's Fall's League on 17 March at Dalymount Park, Dublin.[1]
Given the turbulent political situation in Dublin at the time, Alton United were given an armed escort from Amiens Street Station by the IRA. The Dubliners who were red hot favourites to lift the trophy in only its second year, played well below par and the visitors won it through the only goal.
Alton's players were presented with their medals after the game, but the Football Association of Ireland refused them permission to take the trophy back to Belfast with them due to the tense political situation there. Shortly after Alton affiliated to the Irish Football Association and therefore never defended the trophy the following season.
