Falklands War – History, Causes, Battles, and Casualties

The Falklands War of 1982 was a brief but intense ten-week conflict between Argentina and the United Kingdom over the sovereignty of the Falkland Islands, South Georgia, and the South Sandwich Islands in the South Atlantic. It ended with a British military victory and the surrender of Argentine forces on 14 June 1982, but the underlying dispute over who owns the islands remains unresolved to this day.

The war is widely understood by historians not as a random act of aggression, but as the result of a long-standing sovereignty dispute, domestic political pressures within Argentina, a breakdown in diplomatic negotiations, and British policy decisions that the military junta in Buenos Aires interpreted as a sign of reduced British resolve to defend the remote territory.

For the United Kingdom, the conflict was about recovering the islands, protecting the British population that lived there, and upholding national and international credibility. For Argentina, the invasion was framed as the recovery of territory it considered its own, a cause rooted in deep national sentiment.

Key Facts About the Falklands War

Fact	Details
Invasion Date	Argentina invaded on 2 April 1982, claiming sovereignty over the islands (Las Malvinas).

Political Impact	The war led to the fall of the Argentine military junta and boosted UK Prime Minister Margaret Thatcher’s popularity.

A Deep-Rooted Sovereignty Dispute

The core issue was sovereignty. Argentina claims it inherited the islands, known to them as Las Malvinas, from Spain and argues that Britain’s 1833 takeover was an act of imperial seizure. Britain, meanwhile, argues it has maintained continuous administration and emphasizes the right to self-determination of the island’s population.

Why Did Argentina Invade?

By early 1982, Argentina was ruled by a military junta facing severe economic problems and widespread criticism over human rights abuses. The junta saw the Falklands as a way to rally nationalist public support and divert attention away from domestic failures. Many historians also point to a diplomatic deadlock: years of negotiations had produced no breakthrough, and Argentine leaders became convinced that the British government was unwilling or unable to defend such a distant territory.

What Were the Main Battles and Timeline of the Falklands War?

The war lasted just 74 days but involved significant naval, air, and ground combat. The British task force, which sailed from Portsmouth in early April, had to project power over an 8,000-mile supply line to retake the islands.

Major Military Actions

The British amphibious landing at San Carlos Water on 21 May 1982 established a vital foothold, though the landing force came under heavy attack from Argentine aircraft. The ensuing ground campaign featured several hard-fought battles, including the Battle of Goose Green and the final engagements on the mountains surrounding Port Stanley, such as Mount Longdon, Two Sisters, Tumbledown, and Wireless Ridge.

Ships Sunk and Naval Losses

The war saw notable losses at sea. On 2 May, the British submarine HMS Conqueror sank the Argentine cruiser ARA General Belgrano, an event that became one of the war’s most controversial actions. Just two days later, an Argentine Exocet missile struck the British destroyer HMS Sheffield, which later sank. Argentina’s air attacks proved especially dangerous to British naval vessels.

Falklands War Death Toll: How Many Died on Both Sides?

The human cost of the conflict is one of its most frequently searched aspects, though casualty figures vary slightly depending on the source.

One encyclopedia source provides a broader accounting of the campaign’s end-state, giving Argentine losses as 746 killed, 1,336 wounded, and 11,400 taken prisoner. These different figures reflect the complex nature of counting battlefield deaths versus total losses during the campaign.

The sinking of the ARA General Belgrano was the single deadliest event, accounting for nearly half of the Argentine fatalities. This action remains a subject of historical and legal debate.

Who Won the Falklands War and What Was the Outcome?

Britain won the military conflict, regaining control of the islands on 14 June 1982 when Argentine forces surrendered. The victory was a significant political turning point in both countries. In the UK, it boosted the popularity of Prime Minister Margaret Thatcher’s government and revived a sense of national military capability. In Argentina, the defeat discredited the military junta and paved the way for a return to democratic, civilian rule shortly afterward.

Does Argentina Still Claim the Falkland Islands?

Yes. The war did not settle the sovereignty dispute. Argentina continues to press its claim to the islands. Britain maintains that the islands are a British Overseas Territory and points to the 2013 referendum, in which 99.8% of islanders voted to remain British. The dispute remains a flashpoint in Argentina-UK relations, with recent tensions involving fishing rights and offshore oil exploration.
