Marking the fortieth anniversary of the Falklands War, this special issue brings together new research, and opens avenues for further investigation, on the armed conflict between the United Kingdom and Argentina over sovereignty of the Falkland Islands that stretched between April and June 1982. Across four articles, it explores the broad themes of combatant experience, conflict memory, international relations and policy, from an interdisciplinary investigation of the conflict landscape to an examination of cinematic portrayals of Falklands veterans, and from the application of the lens of the global Cold War to an appraisal of the impact of the conflict on UK defence policy. The special issue also includes a previously unpublished naval memoir of the war, highlighting the continued emergence of new sources that makes the Falklands War a potentially highly productive area of study.
