During the Anglo-Irish War, units of the Irish Republican Army operated in England, conducting propaganda, fund-raising, gun-running, and sabotage campaigns. In Tyneside and elsewhere, they worked closely with the Irish Self-Determination League, a constitutional organization dedicated to advocating for Irish independence. These efforts got underway on Tyneside in early 1920 and are well narrated by Gilbert Barrington in the testimony he submitted to Ireland’s Bureau of Military history. The sabotage campaign, mainly conducted through arson and wire-cutting, was nominally directed from Ireland by Rory O’Connor. It opened in November 1920 with the “Liverpool spectacular,” a series of fires along the Liverpool docks. Arrests slowed the campaign, but it regained momentum in February 1921. In the Newcastle area, IRA members were involved in numerous incidents of arson, including farm fires and attacks on warehouses. Gosforth Aerodrome was burned on April 8, 1921. Some 250 specific instances of damage from this campaign in England and Wales were ultimately itemized when the Irish Free State government and the British government negotiated the payment of damages after the end of the war. Although the campaign failed in its effort to terrorize the English people, it demonstrates that the Anglo-Irish War effectively crossed the Irish Sea.
