It was a silent approach until Corporal Brian Milne stepped on a land mine, which alerted 2nd Lieutenant Juan Baldini's 1st Rifle Platoon (B Company 7th Regiment ''La Plata'') to the attack. At this point the Argentinian sentries opened fire and fierce fighting ensued. Lieutenant Ian Bickerdicke's No. 4 Platoon took the brunt of the enemy machine-gun fire, with several killed and wounded, including the Platoon Commander and Platoon Sergeant. Sergeant Des Fuller, therefore, took command of the remnants of 4 Platoon and moved forward to attack a Marine heavy machine gun position up a steep slope. It was whilst engaging this position that Sergeant McKay was killed in action. He would later receive a posthumous [[Victoria Cross]] for his actions.

Meanwhile, A Company was attacking from the northern side of Mount Longdon. They were coming under heavy, sustained and accurate fire from Staff Sergeant Raúl González's 2nd Rifle Platoon and so the decision was made by Pike to withdraw them from that position. Instead they were to move through B Company and take ‘Full Back’. With Major Argue having finally taken the western peak, Major Collett's A Company moved eastwards, under heavy from Argentinian reinforcements in the form of First Lieutenant Raúl Fernando Castañeda's 1st Rifle Platoon (C Company 7th Regiment).

The Argentinians continued to defend ''Full Back'' but Milan missiles and artillery support systematically destroyed their remaining bunkers. Second Lieutenants John Kearton and Ian Moore mustered their platoons near the western summit and had briefed them on how to deal with the enemy reinforcements. They then attacked First Lieutenant Raúl Fernando Castañeda's 1st Rifle Platoon (C Company 7th Regiment), clearing it of the eastern peak with rifle, grenade and bayonet in close quarters combat.

As A Company was clearing the final positions, Corporal Stewart McLaughlin was wounded by a Czekalski recoilless rifle round fired from the 7th Regiment's Reconnaissance Platoon, he was subsequently killed by a mortar bomb fired from Wireless Ridge as he made his way to the aid post.

Mount Longdon was secure by 09.30 am on June 12. By this time, 3 PARA had been fighting for 12 hours and they would remain under heavy fire for a further 48 hours from Marine Artillery Observation Officers and Mortar Fire Controllers (MFCs) on Mount Tumbledown. During this period an additional four British Paratroopers were killed in action and several more wounded or injured.
