The plan was, as 2 PARA attacked Wireless Ridge, four Rigid Raider fast landing crafts (steered by Sergeant Buckle, Lance-Corporal Gilbert and Marines Kavanagh and Nordic) and carrying some 30 SAS soldiers from D Squadron and six SBS reinforcements from 3 section, would travel across the harbour and destroy the oil storage facilities on Cortley Ridge.

Nevertheless, most of the raiders landed, but heavy fire by a platoon of riflemen under Lieutenant Héctor Gazzolo from the 3rd Marine Infantry Battalion[3] prevented exploitation from the narrow beach,[4] causing the SAS/SBS force to withdraw.

[3] According to John Parker's book SBS: The Inside Story of The Special Boat Service (Hachette, 2013), the four Rigid Raiders were sunk or damaged beyond repair and three British Special Forces were wounded in the attack: A six-man team from 3 SBS ... with D and G Squadrons, SAS, with the object of creating a diversionary assault from the sea ... were to move across the Murrell River by four fast power-boats ...

The RRCs were riddled with holes and had to be destroyed.The wisdom of this attack was later questioned in British circles as it was seen by some as a reckless operation with little strategic benefit.

The Argentine Army Special Forces in Stanley, that were preparing with the Gendarmerie commandos for a major insertion behind British lines on Beagle Ridge, were instead sent aboard the armed transport ship ARA Forrest to help Major Jorge Alberto Monge on Cortley Ridge and the National Gendarmerie Commandos on nearby Navy Point to defend the anti-aircraft guns and round-up any SAS stragglers.
