The Easter Rebellion or Easter Rising of 1916 was a violent confrontation between British forces and Irish Fenian rebels seeking an independent Irish republic. Although the Fenians were brutally defeated, many dying during the battle and several others executed by firing squads afterwards, the method of suppression helped sway public sympathy toward the rebels.
Indiana Jones and Remy Baudouin, during a stopover on the way to London, witnessed the event from the O'Connell Bar where they were holed up. Jones had befriended Fenian Sean Lemass and, with his sister Maggie Lemass, he went to look for him afterwards, learning that he had survived but been arrested.
