Malvinas: The Actions of BIM 5 Obra Company



Account of a Naval Infantry Petty Officer – OBRA Company – BIM 5 Ec (Part 2)

Change of Mission

On 5 June, the company received orders from the Commander of BIM 5 Ec to occupy a Forward Combat Post in the Pony's Pass area. Commander Robacio had long requested that the High Command cover the approach to Port Stanley via the only road connecting Fitz Roy to the town. Without a response from his superiors, he ultimately decided to assign OBRA Company to this mission. This decision impacted the battalion during the Tumbledown engagement, as it lacked a reserve force for a swift counterattack.

We were to position ourselves in the Pony's Pass area. Initially, a reconnaissance was conducted, and the findings were reported to Commander Robacio. He realised that Pony's Pass was not ideal for a Forward Combat Post due to its small hillock surrounded by lagoons and semi-permanent watercourses, all easily fordable by foot troops. Consequently, Lieutenant Miño (of the Amphibious Engineers) was ordered to install a minefield ahead of the future positions, and Sub-Lieutenant Quiroga was instructed to move after reconnaissance and to bring the troops as late as possible, as we were certain the enemy was observing us, and the position needed to remain concealed.

During the night of 11 to 12 June, from OBRA Company's positions, we observed the battles for Mount Harriet. The marines watching the combat could do little, as the British attacks occurred beyond the range of their weapons, 2000 to 3000 metres away, except for an enemy unit attempting a rear assault on Harriet, which came within 800 to 1000 metres of OBRA's weapons.

Petty Officer Tejerina recounts: "On the night of 11 June, after intense naval and land artillery fire, between approximately 2200 and 2300 hours, the enemy launched an assault on the positions at Harriet with machine guns, rocket launchers, and artillery. British artillery fell immediately in front of the first assault line. We saw this clearly from our position, as the tracer rounds from the machine guns indicated the attackers' positions, and occasional flares lit up the area. It was a cold, clear night with a full moon that rose before the attack (21:25). The Company Commander continuously reported the situation to BIM 5 Ec Command. We were ordered to prepare for a potential counterattack. At 0100, combat intensified at the top of Harriet. By 0145, the fighting subsided, with only sporadic machine-gun fire heard. At that time, we recovered two conscripts from the RI 4 Service Section (Conscripts Ibañez and Vallejos), provided them with dry clothing, weapons, ammunition, and Charlie rations; they joined the Company and remained with us until the end of the fighting. Our artillery targeted the attackers; the fire was directed by TCIM Quiroga and GUIM Bianchi of the 1st Section of BIM 5 Ec stationed at William, even firing upon RI 4's own positions east of the mountain. Our commander continuously reported enemy troop movements in the Port Harriet area and their manoeuvre northward towards Mount Harriet. He was particularly concerned about an enemy unit moving northwest."

Petty Officer Tejerina continues: "At dawn on 12 June, enemy troops were seen assembling prisoners on the southern slope of Harriet, then marching them westward. Helicopters were also observed evacuating the wounded. For the rest of the day, we had to remain in our positions to avoid detection. At 1400, enemy artillery shelled our positions with timed ammunition for 30 minutes. (Note: Timed ammunition explodes before hitting the ground, causing a shower of shrapnel.) In this bombardment, a fragment slightly wounded Dragoneante Orlando Garcia, the Rifle Platoon Leader, in the back; he was treated by Second Corporal Medic Angelossi. Dragoneante Garcia refused to leave his position and be evacuated. At 1830, enemy artillery again shelled our area for 30 minutes. I was caught inspecting positions and had to make several dashes to reach the rocket launcher position. Accompanying me was Dragoneante Ariel Bustamante (rocket launcher loader); during one of the bursts, I was hit by the blast wave of a grenade and fell stunned into a water-filled hole, from which Dragoneante Bustamante rescued me instead of seeking cover; he had a habit of accompanying me on my rounds, even under fire."

On 13 June, we detected movements ahead of us, approximately a company of Welsh troops approaching. Artillery fire was requested but fell short; Lieutenant Quiroga made corrections, and then it hit the Welsh troops. We heard screams as they tried to retreat, but the artillery continued to inflict casualties. After a while, they were subjected to heavy fire until Lieutenant Quiroga suspended the fire due to the lack of standing enemy soldiers. I was impressed by the efficiency of the British medical personnel. They wore a type of short white poncho with a red cross on the back, tied at the waist. Some wounded had inflatable splints applied to their limbs, possibly to stop bleeding or fractures. The medics marked the location of the wounded, and then helicopters evacuated them.

Lieutenant Quiroga's Injury

Between 1815 and 1900 hours, while moving between positions, the Company Commander stepped into a hole approximately 20 centimetres in diameter and 50 centimetres deep while taking cover from a nearby grenade explosion, dislocating his ankle. The intense pain immobilised Lieutenant Quiroga, who was quickly attended to by SSIM Orosco and CSEN Angelossi. The latter bandaged Lieutenant Quiroga but suspected a fracture due to rapid swelling and advised him to seek further medical attention at the BIM 5 Ec Aid Post for proper treatment.

After evacuating Lieutenant Quiroga, command was assumed by Lieutenant Calmels. Fog began to form gradually. During twilight, via radio, Petty Officer Tejerina repeatedly instructed his men on the retreat procedure, which theoretically consisted of:

  1. Movement: Withdrawal of Corporal Agüero's group (the most forward) through the bunker, then past the Company CP to a rear assembly point. There, the two groups would occupy positions to cover the retreat of the rest.

  2. Movement: Withdrawal of the 1st Group.

  3. Movement: Withdrawal of the 2nd Group.

Final Movement: Machine guns and 60 mm mortars.

Lieutenant Calmels assumed command around 2200 hours, about fifteen minutes before the attack began. The attack caught him by surprise; he was unaware of the exact situation of his Company. The night, the fog that had begun to lift, enemy fire, and conflicting reports from Group Leaders painted a grave picture; he knew the British were numerous, everywhere, and advancing almost openly, shouting. In reality, the enemy unexpectedly encountered OBRA positions, not anticipating resistance there due to the marines' effective concealment. However, for the Argentinians, the British appeared suddenly, as the fog and artillery noise prevented detection. Combat began when the enemy engaged Corporal Agüero's group, which, as mentioned, was slightly forward, practically on the road, 150 metres from the CP. It's evident that the enemy vanguard was moving along the road, as the group was attacked from the front and right flank (north), threatening its rear. From that moment, combat became generalised. The machine gun left by Corporal Alvarez to Corporal Agüero, previously moved to the northern flank, opened fire. Even from the Company CP, Lieutenant Calmels, Petty Officer Tejerina, Corporal Carrasco, and the Company Platoon Conscripts fired their rifles at the enemy to the north of the position. Grenade explosions were heard. The other two Rifle Groups (1 and 2) prepared for combat, but the British attack did not press on them, receiving only sporadic fire. At that time, it was snowing. The British advanced, supported by a high rate of machine-gun fire—about six or seven—clearly located by their tracer rounds. The enemy gained ground, nearly two companies against a reinforced section.

The Retreat

The retreat could not be executed as planned. In reality, Groups 1 and 2, along with Petty Officer Tejerina, moved towards the Quarry. When the retreat was ordered, the Group Leaders began the movement, but Agüero, who was to initiate it, reported he couldn't move. At that point, the Company Commander ordered his 60 mm mortars to fire on the White Points ahead of the 3rd Group. Some conscripts from this group were seen retreating, but Agüero no longer responded on the radio. By 2300 hours, with the movement underway, Groups 1 and 2 fought their way past the immediate depression behind them and then marched towards the Quarry. Subsequently, the Company Commander withdrew with the Company Platoon and mortar personnel. Petty Officer Orosco remained at the rear, covering the retreat with a machine gun. Briefly illuminated by three flares (two and one), they were forced to "hit the deck." In reality, the illumination was over William. The rest of the Company's retreat occurred in darkness. At 0100 hours, they reached the Quarry, where the Company regrouped. The Company Commander had a mission to fulfil as the Battalion Reserve and immediately marched north towards the Subunit's previous position near the BIM 5 Ec CP. Due to poor terrain information, Lieutenant Calmels expected to find Company RI 3 immediately east of the Quarry, but Captain EA Varela's Company was actually further northeast of William, leaving a gap between Sapper Hill and William.

We returned to our old positions south of the BIM 5 Ec CP. Around 0900 hours, Lieutenant Calmels received orders to retreat to Sapper Hill, where the Battalion was to concentrate for continued combat from that area. Once the Battalion regrouped at Sapper Hill, at 1115 hours, it received orders to retreat to the town. From that moment, the Company joined the rest of the Unit, packed their equipment, and entered Port Stanley. By 1430 hours, the Battalion was already assembled near the Naval Station, and at 1900 hours, OBRA Company, with the bulk of the Battalion, settled in the Naval Station's Carpentry, remaining there until the morning of 16 June when they received orders to move to the Concentration Camp being set up on the airport peninsula. Before entering the area, they had to pass through British control posts, where their weapons were finally confiscated.

Malvinas: A Tribute to the Heroes of BIM 5

Commander Carlos Robacio leads the 5th Marine Batallion 5 in Tumbledown



The 5th Marine Infantry Battalion from Río Grande stood alone against the onslaught of the Scots Guards at Mount Tumbledown, writing a glorious page in history
.


 


During the 74 days of the Malvinas War, British forces were taken aback by the professionalism and fighting spirit of the Argentine troops. There is extensive British literature on the conflict, and all of it acknowledges the courage and resilience of our forces. One particular unit earned, from the British themselves, the nickname “Battalion from Hell” due to its valour and combat effectiveness. These men were the Marines of the 5th Marine Infantry Battalion (BIM 5).

On 7 April 1982, the personnel of BIM 5, based in Río Grande, arrived in the Malvinas under the command of Commander Carlos Robacio. The troops were deployed in the defensive system around Puerto Argentino, together with the Infantry Regiments RI 25 and RI 8. To reinforce the naval forces, Company C of RI 3 and Company B of RI 6 were also added. This integration of Army and Navy units was unprecedented and proved highly effective thanks to the professionalism and commitment of their officers.

From 1 May, the enemy began an aerial and naval bombardment campaign that severely affected the daily life of the Argentine soldiers. During the day, Harrier jets attacked the nearby airstrip and trench lines; at night, the Royal Navy carried out shelling. Despite this, the Marines maintained strong morale and continued to improve their defensive positions, preparing for the ground battle they knew was drawing near.

They endured 44 days of relentless siege. When fighting around Puerto Argentino began on 12 June, the marines of BIM 5 were ready to enter history. The British attack started at dusk and continued through the night. The first unpleasant surprise for the attackers was the presence of heavy machine gun nests equipped with infrared sights, which stalled their advance. Artillery exchanges followed, with the British enjoying an advantage thanks to their longer-range guns and greater mobility. Nevertheless, Argentine artillerymen fought with bravery and professionalism, firing until their last rounds, with barrels glowing red-hot.



On 13 June, the British launched their final offensive. They concentrated all their forces—paratroopers and Royal Marines—achieving a 3-to-1 numerical superiority over our Marines at the main breach. The artillery fire was intense, and naval artillery joined the barrage. Our own artillery, undeterred, responded at a rate of 1,000 rounds per hour, choosing to die on their feet rather than abandon their comrades.

In the late afternoon, the British attempted a flanking manoeuvre via Mount Harriet to distract the Argentine command. Robacio did not take the bait and instead set a deadly trap: he ambushed the enemy, pinning them between a minefield and artillery fire, while positioning Marines at their rear to block retreat. The outcome was heroic. The British were crushed by our artillery and infantry fire. Two hours later, the British company commander requested a ceasefire, citing the harrowing cries of the wounded as demoralising his troops. This ceasefire allowed the arrival of helicopters to evacuate the injured. No shots were fired at the helicopters, which were unarmed and clearly only conducting medical evacuation.

In the early hours of 14 June, the Scots Guards moved to the centre of the assault on Puerto Argentino. The firefight was intense. So many tracer rounds filled the sky that it seemed like daylight. In the final moments of the assault, the fighting became hand-to-hand. Argentine forces repelled the attack with fixed bayonets and requested artillery and mortar fire directly on their own positions, as the enemy had reached them. Second Lieutenant Silva and NCO Castillo called for a counterattack after being overrun. They left their positions and launched a bayonet charge until they were killed.

Commander Robacio personally led the counterattack, retaking lost positions and pushing the Scots Guards back to their original lines. By 3 a.m., amid a heavy snowfall, the Marines prepared another counteroffensive against the British paratroopers and requested authorisation as their forward units engaged the enemy. The order from Puerto Argentino was to withdraw, as it had become impossible to resupply 105 mm howitzers and mortars. Despite this setback, morale remained high, and it was difficult to convince the Marines to abandon their positions. With iron discipline, they withdrew from Mount Tumbledown and fell back.

A well-executed withdrawal under enemy pressure is one of the most difficult manoeuvres in military doctrine. History offers many examples of such withdrawals turning into deadly routs. But with pride, the Marines of BIM 5 took up new positions on the outskirts of Puerto Argentino, still determined to fight. Gurkha troops were dispatched to pursue the Argentines to make up for the Scots' poor performance, but they were halted and counterattacked—even though our men had run out of ammunition.

At dawn on Monday, 14 June 1982, BIM 5 had no ammunition left. In 36 hours, they had fired 17,000 artillery shells and all their mortar rounds. At 10 a.m., the ceasefire order came from Puerto Argentino. The battalion was still in combat formation. Commander Robacio requested confirmation of the order. His unit entered the capital of the islands in full marching formation, carrying all their personal weapons. Tragically, a section of the Navy Company that had been separated did not receive the order and at 12:30 engaged a landing of six British helicopters, shooting down two and suffering the loss of the last three Argentine soldiers in combat.

In military history, few units have endured 44 hours of bombardment without relief and then faced the enemy with such courage and determination. The Argentine forces at Tumbledown included 700 Marines and 200 soldiers, who confronted 3,000 of the best-trained troops of the British Armed Forces. Seventy-five per cent of our heroes were conscripts. BIM 5 suffered 30 killed and 105 wounded, inflicting an estimated 360 casualties on the enemy (a figure never officially recognised, though many British officers have acknowledged it privately).

How did they endure such hardship and fight with such determination? BIM 5 and RI 25 were the only units acclimatised to the Malvinas. They were well equipped, and their officers were professional and competent. They also shared a remarkable esprit de corps. As an example: on 14 June at 10:30, during the retreat to Sapper Hill, Commander Daniel Ponce collapsed from exhaustion. Amid gunfire, two conscripts rushed to carry him. Ponce ordered them to leave him and flee. Their reply: “Captain, if we die, we die together.” They lifted him and withdrew. That was the spirit of the marines of BIM 5, who gave everything for their country.

Malvinas: Tumbledown Night

Tumbledown: Blood and Courage





The Battle of Mount Tumbledown: A Nocturnal Clash in the Malvinas War

The Battle of Mount Tumbledown took place on the night of June 13–14, 1982, as part of the British campaign to recapture Puerto Argentino, the capital of the Malvinas Islands. It was a brutal, close-quarters fight in freezing, rugged terrain, pitting the Argentine 5th Marine Infantry Battalion (BIM 5) against a British force comprising the 2nd Battalion Scots Guards, the 1st Battalion 7th Gurkha Rifles, elements of 42 Commando Royal Marines, and supporting units like the Welsh Guards and Blues and Royals. The battle’s savagery stemmed from its nocturnal setting, the rocky landscape, and the desperate stakes for both sides.


The Setting: A Dark, Hostile Landscape

Imagine a moonless night, the Malvinas’ winter wind slicing through the air, temperatures hovering near freezing. Mount Tumbledown, a jagged, 750-foot-high ridge of crags and boulders, looms west of Stanley. Its slopes are slick with wet peat and frost, littered with rocks perfect for defensive positions. The Argentine 5th Marines, under Commander Carlos Robacio, are dug into trenches and sangars (stone shelters), their positions fortified with machine guns, mortars, and snipers. They’re cold-weather trained, hardened, and determined to hold this key height overlooking the capital. On the British side, soldiers huddle in the darkness near Goat Ridge, their breath visible as they prepare for a silent advance, weighed down by packs, rifles, and anti-tank weapons.

The Opening Moves: Diversion and Stealth

Picture the battle starting at 8:30 p.m. local time. A diversionary attack kicks off south of Tumbledown—four light tanks from the Blues and Royals (two Scorpions, two Scimitars) rumble forward, their engines roaring, accompanied by a small Scots Guards detachment. Their muzzle flashes light up the night, drawing Argentine fire. Meanwhile, the main assault begins from the west: three companies of Scots Guards—Left Flank, Right Flank, and G Company—move silently in phases, bayonets fixed, under cover of darkness. Mortar teams from 42 Commando set up behind, ready to rain shells, while naval gunfire from HMS Active’s 4.5-inch gun booms offshore, its explosions illuminating the horizon in brief, eerie flashes.


The Clash: Savage Close-Quarters Fighting

Visualize the moment the Scots Guards hit the Argentine lines. Left Flank Company, leading the assault, creeps undetected to the western slopes—then a Guardsman spots an Argentine sniper. A single shot rings out, followed by a volley of 66mm anti-tank rockets streaking through the dark, their fiery trails briefly exposing the enemy. The Guards charge, machine-gunners and riflemen firing from the hip, a chaotic line of muzzle flashes advancing over open ground. Argentine marines of N Company, entrenched with FAL rifles and MAG machine guns, return fire—tracers arc across the night, ricocheting off rocks. Grenades explode, showering shale and dirt; bayonets clash in brutal hand-to-hand combat. The air fills with shouts, screams, and the metallic clatter of weapons.

Halfway up, Left Flank’s 15 Platoon, under Lieutenant Alasdair Mitchell, takes heavy casualties—two men fall dead, others wounded, their blood staining the rocks. Right Flank Company, under Major John Kiszely, pushes east, meeting fierce resistance from Marine Sub-Lieutenant Carlos Vázquez’s 4th Platoon. Phosphorous grenades burst, casting a ghastly white glow, revealing Argentine defenders fighting from crag to crag. The Scots Guards lose eight dead and 43 wounded in this relentless grind, their red tunics (in spirit, if not literal uniform) soaked in sweat and blood.


The Gurkhas and Mount William: A Parallel Struggle

Now shift your gaze south to Mount William, a sub-hill held by the Argentine O Company. The 1st Battalion 7th Gurkha Rifles, held in reserve initially, moves in after Tumbledown’s summit is secured. Picture Gurkhas in camouflage, kukris gleaming faintly, advancing across a shell-pocked saddle under Argentine mortar fire from Sapper Hill. Eight are wounded as shells burst in the soft peat, muffling some blasts but not the chaos. They take Mount William by 9:00 a.m., their disciplined advance a stark contrast to the earlier melee, yet no less determined. Robacio would say "We're not afraid of them, they fell like flies". They were humans after all.

 

The Welsh Guards and Sapper Hill: Delayed but Deadly

Imagine the Welsh Guards, paired with Royal Marines, stuck in a minefield en route to Sapper Hill. Their frustration mounts as Argentine mortars pound them from above, one man killed earlier on a motorbike dispatch. They’re meant to follow the Gurkhas but are bogged down, their silhouettes barely visible in the pre-dawn murk, cursing the delay as shells whistle overhead.

 

The Argentine Retreat: A Final Stand

See the Argentine 5th Marines’ resolve crack as dawn nears. A sniper—perhaps Private Luis Bordón—fires at a British Scout helicopter evacuating wounded, injuring two Guardsmen before being cut down in a hail of Scots Guards gunfire. By 9:00 a.m., the Scots Guards hold Tumbledown’s eastern high ground, and the Gurkhas secure Mount William. Commander Robacio plans a counterattack from Sapper Hill, but his men—16 dead, 64 wounded—begin a disciplined retreat toward Puerto Argentino, marching in parade order, colors high, defiant even in defeat. Thirty Argentine bodies lie scattered across the battlefield, a testament to the fight’s ferocity. As soon as Robacio arrives, ask the Militar Governor Menéndez to send all of his men to the front. He was disregarded.



The Aftermath: A Hard-Won Victory

Envision the scene at sunrise: British troops, exhausted, consolidate their positions. The Scots Guards’ Pipe Major James Riddell stands atop Tumbledown, his bagpipes wailing “The Crags of Tumbledown Mountain,” a haunting tribute to the fallen. A Volvo BV-202 lies wrecked by a mine, its crew dazed. The British tally: 10 dead (8 Scots Guards, 1 Welsh Guard, 1 Royal Engineer), over 60 wounded. Medals—DSOs, Military Crosses, Distinguished Conduct Medals—will follow, but for now, the survivors catch their breath, the road to Puerto Argentino open at last.
