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.
