Battle of Mount Longdon

Battle of Mount Longdon was a pivotal night assault during the Falklands War, fought between the British 3rd Battalion, Parachute Regiment and entrenched Argentine forces on 11–12 June 1982. The intense close-quarters combat for the strategic high ground was one of the bloodiest engagements of the conflict, directly enabling the subsequent Battle of Wireless Ridge and the final push towards Port Stanley. Its ferocity and high casualty rate left a profound mark on the memories of both British and Argentine veterans.

Background

The conflict originated in the longstanding dispute over sovereignty of the Falkland Islands, known as the Islas Malvinas in Argentina, which culminated in the 1982 invasion of the Falkland Islands by forces loyal to the Argentine junta under Leopoldo Galtieri. In response, the United Kingdom dispatched a naval task force, leading to a series of battles including the Battle of San Carlos and the Battle of Goose Green. Following the British victory at Goose Green, the focus shifted to breaking the defensive ring of mountains and hills surrounding the Argentine garrison in the capital, Port Stanley. The capture of these key positions, part of a coordinated offensive, was essential for the final assault on the capital.

Prelude

In early June, the British 5th Infantry Brigade and 3 Commando Brigade began advancing from the San Carlos Water bridgehead towards the outer defenses of Port Stanley. Mount Longdon, a rugged, rocky outcrop approximately five miles west of the capital, was a critical component of the Argentine defensive perimeter, codenamed the "Ring of Steel". It was defended by elements of the B Company, 7th Infantry Regiment, reinforced by a detachment from the elite Argentine Marines, under the overall command of Lieutenant Colonel Carlos H. Carrizo-Salvadores. The British plan, formulated by commanders including Brigadier Tony Wilson, involved a silent night attack by the 3rd Battalion, Parachute Regiment (3 Para), commanded by Lieutenant Colonel H. Jones until his death at Goose Green, with the battalion now led on the ground by officers like Major Mike Argue.

Battle

The assault began in freezing conditions after midnight on 11 June. The lead company's approach was compromised when a paratrooper triggered an anti-personnel mine, alerting the Argentine defenders and turning the planned silent attack into a furious, direct firefight. The British faced intense machine-gun and sniper fire from well-prepared positions, including heavy FN MAG and Browning M2 fire, and were subjected to artillery and mortar bombardment from Argentine batteries firing from Mount Tumbledown and Wireless Ridge. Fierce close-quarter combat ensued among the rocks, with notable acts of bravery including the actions of Sergeant Ian McKay, who was posthumously awarded the Victoria Cross for storming an enemy machine-gun post. After several hours of brutal fighting, and with support from Naval Gunfire Support from ships like HMS Avenger, 3 Para secured the summit by dawn on 12 June.

Aftermath

The victory came at a high cost, with 3 Para suffering 23 killed, including Lieutenant Colonel H. Jones's successor as CO, and 47 wounded, making it one of the single most costly battles for the British during the Falklands War. Argentine casualties were also severe, with estimates of 31 to 50 killed, approximately 120 wounded, and 50 taken prisoner. The fall of Mount Longdon, along with simultaneous British victories at the Battle of Two Sisters and the Battle of Mount Harriet, shattered the western sector of the Argentine defensive ring. This directly enabled the subsequent assaults on the final outer defenses, Mount Tumbledown and Wireless Ridge, leading to the general Argentine surrender in Port Stanley just days later.

Legacy

The battle is remembered as a testament to the extreme hardship and ferocity of infantry combat in the Falklands. It is commemorated annually by the 3rd Battalion, Parachute Regiment and is a focal point for veterans' associations from both nations. The heroism displayed, particularly that of Sergeant Ian McKay VC, is enshrined in British military history. In Argentina, the defense of Mount Longdon is honored as part of the national narrative of the war. The conflict's outcome solidified British control over the Falkland Islands but left a deep and enduring legacy of loss and remembrance for the soldiers and families involved on both sides.
