Battles of Mount Harriet and Two Sisters Mountain

Following Operation Rosario (Falklands/Malvinas War), the Argentinian occupation of the Falkland/Malvinas Islands, 42 Commando and 45 Commando (40 and 45 CDO) of the British Royal Marines were deployed as part of Brigadier Julian Thompson's 3 Commando Brigade to retake the islands in Operation Corporate.

British advance

Following Kilo Company's helicopter flight forward on the night of May 31st to reinforce D Squadron 22nd Special Air Service (SAS) Regiment defending Mount Kent from Argentinian Special Forces attacks, the rest of 42 Commando arrived in helicopters, and were eventually ordered to secure Mount Challenger.

45 Commando's march to Bluff Cove Peak from San Carlos Water via Teal Inlet ended on June 4th, and the next week was spent patrolling No-Man's-Land, leading to a number of bloody clashes with the Argentinians. On their second patrol, Lieutenant Chris Fox's Recce Troop reached the western end of Two Sisters, and when discovered, were counterattacked but killed five of the Argentinians. Later, Lieutenant David Stewart 3 Troop of X-Ray Company, 45 Commando retreated in a similar action, abandoning much equipment, and Lieutenant Mark Townsends's 1 Troop from Kilo Company, 42 Commando had raided the forward Argentinian positions on Mount Harriet from Goat Ridge. Also, Sergeant Ian Allum's Recce Platoon from the 2nd Scots Guards Battalion completed their mapping out of the Argentinian positions from their cover in Port Harriet House. Sadly these successes did not come without loss. On the night of June 9th a fighting patrol from Yankee Company was caught between the machinegun fire of Argentinian Special Forces and supporting mortarmen near Murrell River, resulting in the deaths of four Royal Marines.

45 Commando's night attack would also be silent without any preliminary artillery fire. Lieutenant-Colonel Whitehead's plan was for X-Ray Company to leave their start line at 9.00 pm, and having taken the south western peak (Long Toenail) around two hours later, to set up a fire support base that included 40 Commando's Milan Troop. Zulu Company would then assault the northern peak (Summer Days), and Yankee Company the eastern end of Two Sisters.

On June 11th, 45 Commando less X-Ray Company left their positions behind Mount Kent and moving around the north side, reached the main start line (Pub Garden) as planned. Meanwhile, X-Ray Company, marching down between Mount's Kent and Challenger and heavily weighed down, especially by the Milans, arrived at the start line over two hours late. After a short rest, they began their move towards Long Toenail at 11.00 pm local time.

Two Sisters

X-Ray Company headed across the open ground towards Long Toenail led by Lieutenant James Kelly's 1 Troop, and less than a mile short of the peak, Lieutenant David Stewart's 3 Troop took over the lead, but halfway up was stopped by heavy machine gun fire and forced back. The enemy positions were hit by Milans and some mortar fire, and now Lieutenant Chris Caroe's 2 Troop pushed on to the summit under naval artillery fire. Reaching there, they were forced back by Argentinian shellfire, but shortly returned driving off the Argentinian 3rd Platoon. Soon after midnight as X Company continued its fight for Long Toenail, Zulu Company followed by Yankee Company to their right, moved off from Pub Garden on their silent uphill approach. As the Argentinian 1st and 2nd Platoons were still distracted by X-Ray Company's attack, the other two companies went to ground until a flare near Zulu Company led to the right hand 8 Troop opening fire. The return enemy fire including mortars and artillery was so heavy, killing four men, that Lieutenant Clive Dytor led his men of 8 Troop forward in a bayonet charge towards the summit, followed by 7 Troop in a firefight that still left them short of their objective.

On their right, Yankee Company swung further right to come up alongside them, managing to knock out some of Major Cordon's machine guns holding up Zulu Company. 8 Troop was then able to advance towards the top covered by 7 Troop, and went on to clear enemy positions on the southern side of their objective, while 7 Troop went on to do the same on the northern side. Two and a half hours after crossing the start line, Zulu Company had taken the enemy strongpoint of 'Summer Days'. During this time, 9 Troop stayed back in reserve after suffering casualties from Major Jaimet's mortars. Yankee Company now moved between the Two Sisters peaks and below Zulu Company's 8 Troop, and headed for the eastern part of Two Sisters under heavy fire. Pushing on, and again using anti-armour weapons against enemy positions, all of Two Sisters was in 45 Cdo's hands before dawn. As they reorganized and dug in, heavy Argentine shelling started. Lieutenant-Colonel Whitehead prepared to move ahead towards Tumbledown Mountain, but was stopped by Brigadier Thompson. 45 Commando had now taken one of the main Argentine defenses for the loss of seven Marines and a Sapper of the Royal Engineers killed by small-arms and mortars.

Sergeant-Major George Meachin of Yankee Company, later praised the fighting abilities and spirit of the Argentinian defenders:

“

We came under lots of effective fire from 0.50 calibre machine guns …At the same time, mortars were coming down all over us, but the main threat was from those machine-gunners who could see us in the open because of the moonlight. There were three machine-guns and we brought down constant and effective salvoes of our own artillery fire on to them directly, 15 rounds at a time. There would be a pause, and they’d come back at us again. So we had to do it a second time, all over their positions. There’d be a pause, then ‘boom, boom, boom,’ they’d come back at us again. Conscripts don’t do this, babies don’t do this, men who are badly led and of low morale don’t do this. They were good steadfast troops. I rate them.

”

Harriet

While Kilo Company was fighting on the eastern end of the summit and coming under artillery fire, Lima Company was making its way up the southern slopes of Mount Harriet under heavy machine gun fire from Second Lieutenant Pablo Oliva's platoon of conscripts which opened fire soon after Captain Wheen's men crossed their start-line. British artillery fire and MILAN anti-tank missiles were successful in knocking out these and other enemy machine-gun sangars, but it took a number of hours and 14 wounded from Argentinian artillery and automatic fire, before Lima Company's half of the summit was taken, still in the dark. Lieutenant Jerry Burnell's 5 Troop of Lima Company was then sent forward to the next objective just to the north of the summit, but was initially held up until the defenders in Second Lieutenant Lautaro Jiménez Corbalán 3rd Rifle Platoon crumbled under heavy nachine-gun, mortar and artillery fire.

With dawn and Lima Company still fighting forward, Juliet Company was ordered on to Goat Ridge, by which time Kilo Company had captured the summit. In successfully taking its objective, 42 Commando had lost two killed and thirty wounded.

Aftermath

The battles proved good planning and deception was effective even against a resolute enemy in good defensive positions. Ten Marines were killed and fifty wounded. Forty Argentinians were killed defending Mount Harriet and Two Sisters Mountain. The Royal Marine platoon and company commanders were much impressed with the conduct and fighting spirit of the Argentine conscripts and regulars and were forced to correct critics who were under the impression that the conscripts caved in after the first shots had been fired.

Lieutenant Chris Caroe, a 21-year-old platoon commander in the action, in an interview with the Chester Chronicle in 2012, reported that Despite being a conscript army... the Argentinians were a force to be reckoned with because they were led by skilled regulars. For Lieutenant Cliver Dytor, who had joined the Royal Marines in 1980, the Argentinian heavy machine-gunners and stay-behind snipers on Two Sisters had fought to the death, The Argentine marines all fought to the end and were killed with bullets and bayonets. We had to fight through lots of positions, clearing the enemy.
