Operation Algeciras was a foiled Argentine plan to sabotage a Royal Navy warship in Gibraltar during the Falklands War. The Argentine reasoning was that if the British military felt vulnerable in Europe, they would decide to keep some vessels in European waters rather than send them to the Falklands. A commando team observed British naval traffic in the area from Spain during 1982, waiting to attack a target of opportunity when ordered, using frogmen and Italian limpet mines.
