The Battle of Mount Harriet was an engagement of the Falklands War, which took place on the night of 11/12 June 1982 between British and Argentine forces. It was one of three battles in a brigade-size operation on the same night.
The British force consisted of 42 Commando (42 CDO), Royal Marines under the command of Lieutenant Colonel Nick Vaux's Royal Marines (he later became a general) with artillery support from a battery of 29 Commando Regiment, Royal Artillery. The 1st Battalion, Welsh Guards (1WG) and two companies from 40 Commando (40 CDO) were in reserve. HMS Yarmouth provided naval-gunfire support for the British forces. The Argentine defenders consisted of ex-Army Green Beret Captain Carlos Alberto Arroyo's B Company from Lieutenant Colonel Diego Alejandro Soria's 4th Monte Caseros Infantry Regiment (RI 4).
On the night of 30 May, K Company of 42 CDO boarded three Sea King helicopters and moved forward of San Carlos to secure the commanding heights of Mount Kent—at 1,504 feet, the tallest of the peaks surrounding Stanley—where the D Squadron SAS Troops had already established a strong presence. However, when they arrived at their landing zone, some 3 kilometres (2 miles) behind the ridge of the mountain, the Marines were surprised to see the flashes and lines of tracer ammunition lighting up the night.
After a second clash with the 15 SAS men from 17 Boat Troop, the Argentine patrol (under Captain Tomas Fernandez' 2nd Assault Section, 602 Commando Company) abandoned their hideouts among the boulders and caves on Mount Kent. By the end of May, D Squadron under Major Cedric Delves had gained Mount Kent at the cost of two wounded in Air Troop, and Boat Troop with Tactical HQ commenced patrolling Bluff Cove Peak, Mount Challenger and Estancia House, which they took with the loss of another two SAS wounded, including one Spanish-speaking warrant officer attached from 23rd Special Air Service Regiment (Reserve) that had joined Delves to properly interrogate the captured Argentine Army Special Forces. At the same time Captain Matthew Selfridge's D Company scouting ahead of 3 PARA took Teal Inlet Settlement, at the cost of one wounded through an accidental discharge.
The rest of 42 Commando made a desperate march across the hills north of Mount Simon to reinforce Mounts Kent and Challenger overlooking Port Stanley. The weather conditions were atrocious, with the Marines marching through steep slippery hillocks and stone-runs to their objectives. Lou Armour was a corporal in J Company under Major Mike Norman:
Because of the weather and lack of equipment, we just had to carry all our heavy equipment back to Mount Kent, instead of being flown there. That was psychologically the toughest thing I'd ever done. You're walking and falling, walking and falling—some of the lads carrying up to a hundred pounds—and if you fell over, it took two guys to lift you back up. Then there was the lack of sleep, the wet, the cold, the diarrhea.
The final attack was preceded by many days of observation and nights of patrolling. Some night-fighting patrols were part of a deception plan to convince the Argentinians that the attack would come from a westerly direction. Other, more covert, patrols were to find a route through a minefield around the south of Mount Harriet. Sniping and naval artillery were used to harass the defenders and deny them sleep.
On 3 June, Lieutenant Chris Marwood's Reconnaissance Troop of 42 CDO on Mount Wall, accompanying the 3 Commando Brigade Forward Air Control team commanded by Flight Lieutenant Dennis Marshall-Hasdell, encountered an RI 4 fighting patrol (Second Lieutenant Lautaro Jiménez Corbalán's 3rd Platoon of B Company from Mount Harriet). The Recce Troop opened fire and two conscripts (Privates Celso Paez and Roberto Ledesma) were instantly killed, and an NCO (Corporal Nicolas Odorcic) went down, concussed when shot in the helmet by one of the Marine snipers.
This action drew attention to their exposed forward position, and Argentine reinforcements in the form of Second Lieutenant Marcelo Llambías Pravaz's 3rd Platoon from Two Sisters joined the action with a counterattack firing rifle-grenades. The Primary Forward Air Controller, commando-trained Flight Lieutenant Dennis Marshal-Hasdell, remembers:
We were separated from our heavy bergens with the radios and all our gear. The patrol was spread over quite a large area, with lots of shouting, noise and firing going on. The Marines abandoned all their equipment, and although no one told us, it became clear that we were to withdraw. With no information, and the likelihood of having to fight our way out, Dave Greedus and I decided to abandon our equipment, destroying as much as we could. The two radio sets (HF and UHF) were tough enough, but the HAZE unit of the laser target marker was designed to withstand the weight of a tank!
The laser target designator retrieved in the contact showed that the Royal Marines were seeking to destroy the Argentine bunkers on Mount Harriet with 1,000-pound GBU-16 Paveway II dropped by RAF Harriers. The next day, Lieutenant Tony Hornby's 10 (Defence) Troop re-occupied the Mount Wall observation post against no opposition.However, on the night of 5-6 June, Captain Andrés Ferrero's 3rd Assault Section attacked Lieutenant Hornby's men on Mount Wall. After a sharp fight the Royal Marines were forced to withdraw.
On 8 June crack reinforcements in the form of machine-gunners and mortarmen from the 1st 'Patricios' Infantry Regiment, Regiment of Mounted Grenadiersand 17th Airborne Infantry Regimentarrived from Comodoro Rivadavia to support the 4th Infantry Regiment. On the night of 8–9 June, action on the outer defence zone flared when Lieutenant Mark Townsend's 1 Troop (K Company, 42 CDO) probed Mount Harriet, killing two Argentines (Corporal Hipolito Gonzalez and Private Martiniano Gomez) from Second Lieutenant Jiménez Corbalán's 3rd Platoon. At the same time, two platoon-size fighting patrols from 45 Commando attempted the same on Two Sisters Mountain, but the Argentine RASIT ground surveillance radar on Mount Longdon was able to detect the 45 Commando platoons, and artillery fire dispersed the force. According to the British, Lieutenant Townsend's men killed six Argentines in the 3rd Platoon positions that night, with Y Troop reportedly intercepting Argentine signals from the 4th Regiment that confirmed the loss of six Argentines in the forward positions at the hands of the Royal Marines. In all, Second Lieutenant Lautaro Jiménez Corbalán would report the loss of 6 killed and 14 wounded fighting Lieutenant Marwood's Recce Troop on Mount Wall, Lieutenant Towsend's 1 Troop on the night of 8-9 June and the final assault carried out by L Company on Mount Harriet.
Around dusk on 9 June, Lieutenant-Colonel Soria's men detected the presence of British troops that had taken up positions in a house on the southern approaches to Mount Harriet. The 4th Regiment's Reconnaissance Platoon under Sub-Lieutenant Jorge Pasolli received instructions to move forward and clear the British from Port Harriet House and the Scots Guards Reconnaissance Platoon that had moved into the area was forced to vacate the building when the Argentines radioed in mortar fire support from the 120-mm Mortar Platoon on Mount Harriet and Pasolli's men attacked. The Scots Guards fired back at the Reconnaissance Platoon with two Bren machine guns but were forced to abandon their rucksacksand radiosand retreated to North Basin under heavy small arms and mortar fire that wounded three men including Sergeant Ian Allum.
Over a period of a week, the 4th Regiment defended the Harriet-Two Sisters sector from five Royal Marine platoon-sized attacks. Every time the Royal Marine Commandos got into the forward platoon positions, the officers, NCOs and conscripts, in general, counterattacked with rifles and cleared them out.
On the morning of 11 June, the orders for the attack were given to 42 CDO by Vaux; K Company was ordered to attack the eastern end of the mountain, while L Company would attack the southern side an hour later, where it—if the mountain was secured—would then move north of Mount Harriet to Goat Ridge. J Company would launch a diversionary attack (code named Vesuvius) on the western end of Mount Harriet.
In the closing hours of 11 June, K and L Companies moved from their assembly area on Mount Challenger (which lay to the west of Mount Harriet) and made their way south, around their objective, across the minefield, to their respective start lines. As they moved around the feature in the dark, J Company and supporting Welsh Guards launched their very loud diversionary "attack" from the west.
The battle for Mount Harriet began on the evening of 11 June with a blistering naval bombardment that killed two Argentinians and wounded twenty-five. John Witheroe, one of the British war correspondents, later recalled the softening up fire:
We were involved with one night attack on Mount Harriet, when the Welsh Guards were coming up as a back-up. This involved marching for several hours on a very dark night, through a minefield. Sporadic shellfire slowed our progress tremendously. Eventually we made the base of Mount Harriet, which was coming under incredible fire from a frigate off shore. The whole mountain seemed to erupt in flame. It seemed impossible that anybody could survive an attack like that. This went on for well over an hour, shell after shell whistling over our heads and hitting the mountain. Eventually this was lifted and the Marines went in. To our amazement, there seemed to be an incredible amount of fighting going on. There was a lot of tracer fire. The whole night was being lit up by flares, which cast a dead, unrealistic, pall over the whole scene.
The Argentines retaliated and the Artillery Observation Officer on Mount Kent, Captain Tomás Fox, directed 155mm artillery rounds that fell among the men of 'B' Company, 7th Duke of Edinburgh's Own Gurkha Rifles in the area of Bluff Cove, seriously wounding three Gurkhas, including Lance Corporal Gyanendra Rai who nearly bled to death. Describing the moment he was injured, Rai, who was awarded the South Atlantic Medal, said: "I was absolutely convinced I would die. I was in severe pain. It was like someone had driven a four-pound sledge hammer through the side of my back."
Captain Peter Babbington's K Company crossed their start line first and proceeded up the mountain undetected, knifing two sentries on the way. They remained undetected until they approached Sub-Lieutenant Mario Juarez' 120-mm Mortar Platoon positions and decided to engage them. They were assisted in the advance by HMS Yarmouth, artillery, and mortars. During the engagement, Second Lieutenant Juarez was wounded and Corporal Laurence G Watts from K Company was killed. The supporting British artillery batteries and mortar crews fired over 1,000 rounds to keep the Argentines pinned down, and helped stop the defenders getting a proper aim at the Royal Marines.
About 150 metres from Soria's HQ, Corporal Steve Newland circled behind a group of Argentines (under First Lieutenant Jorge Alejandro Echeverria, the 4th Regiment's intelligence officer) who were setting up an ambush. Although half a platoon of Argentine riflemen and a MAG were placed to engage anyone who broke cover, Newland darted out from under cover to charge the enemy machine gun. He grenaded two of the crew, but reaching the rear of the machine gun position, he was shot through both legs.
With the enemy machine gun out of action, Corporals Steve Newland, Mick Eccles and Chrystie 'Sharky' Ward were able to clear the position with some help from Marine Barnett. The three corporals were awarded the Military Medal and Barnett the MID. Increasing numbers of Argentine soldiers, mainly shocked and dazed conscripts from RI 4's Recce Platoon, Reserve Platoon and 120-mm Mortar Platoon began to surrender, but several experienced officers (First Lieutenants Francisco Pablo D'Aloia, Esteban Guillermo Carlucci and Luis Oscar García) and several senior NCOs still fought on, according to their orders. The RI 4 Commanding Officer and First Lieutenant Rubén Cichiara, despite heavy British fire, linked up with B Company and ordered Arroyo's men to counterattack. The heavy machine gun teams, in general, stood in their positions continuing the fight.
Captain David Wheen's L Company crossed their start line shortly after K Company and were almost immediately engaged by effective machine gun fire from Sub-Lieutenant Pablo Oliva's platoon defending the lower southern slopes. Kim Sabido, the IRN reporter with L Company, reported the action:
For a couple of hours it seemed as if it might all go wrong. Pinned down on the slopes by heavy machine gun and sniper fire, progress was painfully slow. I saw several men fall with bullet wounds, others were hit by flying fragments from the constant barrage of long-distance high-explosive shelling. The men in front of us were not giving up without a bitter fight.
Thee weapons in Oliva's platoon would not be silenced until being hit by several MILAN anti-tank missiles and six 105mm artillery guns from Mount Challenger, killing 3-4 of Oliva's men. The L Company Marines took 5 hours to advance 600 metres in the face of reinforcements in the form of Sub-Lieutenant Eugenio César Bruny's RI 4 Platoon and contend they took fire from at least seven machine guns that wounded five men, including the company's second-in-command and a signaller. British military historian Hugh Bicheno reports that the 4th Regiment's passive night goggles were all with Arroyo's B Company. Another 11 Marines in Wheen's Company were wounded by Argentine shellfire that Lieutenant-Colonel Soria personally brought down attempting to halt the British advance.
Before first light, Lieutenant Jerry Burnell's 5 Troop of L Company proceeded to an outcrop of rocks towards Goat Ridge. As they advanced, the Royal Marine platoon came under heavy fire from Second Lieutenant Jiménez Corbalán 3rd Platoon, covering the Argentine retreat and were forced to withdraw under cover of machine guns pre-positioned behind them and further up the hill. The Troop took one casualty in this action. L Company requested mortar fire onto the Argentines; a mixture of HE and WP; then 5 Troop moved forward again, this time supported by 15 machine-guns. They took 3 prisoners although most of Jiménez-Corbalán men had withdrawn after losing two killed in the night fighting (Privates Juan José Acuña and Carlos Epifanio Casco). The platoon of Oscar Augusto Silva continued to resist from Goat Ridge throughout the morning of 12 June, and a determined conscript (Orlando Aylan), in a position just below the summit of Mount Harriet held up L Company with accurate shooting until killed by an 84mm anti-tank rocket fired at short range. At some time in the early morning darkness, as Second Lieutenant Jiménez Corbalán's 3rd platoon was making its way to new positions on Mount William, the officer was concussed and temporarily blinded when he set off a booby-trap while leading his men through a minefield. At great risk to themselves, Privates Teodoro Flores and Carlos Salvatierra rescued their platoon commander and were later decorated for their bravery.
The battle was a textbook example of good planning and use of deception and surprise, and a further step towards the main objective of Stanley. Two Royal Marines: Corporal Laurence G Watts and Acting Corporal Jeremy Smith were killed, and thirty were wounded, including fourteen wounded in L Company. Another six Scots Guards and Gurkhas were wounded by Argentine artillery and mortar fire controllers on Mount Harriet. Eighteen Argentines were killed defending Mount Harriet, including those killed in the earlier patrol battles and softening up bombardments. Lance Corporal Tony Koleszar had the surprising experience of finding that two 'dead' Argentine soldiers, whose boots he was trying to remove, were very much alive and jumped up to surrender. Some British reporters were thus misled into depicting the Argentineans as hapless teenage conscripts who caved in after the first shots were fired, but Royal Marine Warrant Officer 2 John Cartledge, who served with L Company during the battle, corrected them, saying the Argentines were good soldiers who had fought properly:
They used the tactics which they had been taught along the way very well, they were quite prepared for an attack. They put up a strong fight from start to finish. They were also better equipped than we were. We had first generation night sights, which were large cumbersome pieces of equipment, while the Argentines had second-generation American night sights that were compact and so much better than what we had. The one deficiency which we exposed was that they had planned for a western end of the mountain attack and therefore had not bothered to extend their defensive positions to the eastern end, where we ultimately attacked.
One British general put their success down to his Marines' skill and professionalism:
What was needed was speed but not being bloody stupid. The Israelis would have done it much faster, but with many more casualties.
42 Commando captured 300 prisoners on Mount Harriet, and for the bravery shown in the attack, the unit was awarded one DSO, one Military Cross, four Military Medals, and eight men were mentioned in dispatches.
In 2017, David Wheen traveled to Argentina to meet Lautaro Jiménez-Corbalán. In an act of reconciliation, Wheen presented Jiménez-Corbalán with a British military essay and painting of the battle while receiving a copy of his book Malvinas en Primera Línea, that recounted the experiences of the 4th Regiment in the Falklands.
