Following Kilo Company's helicopter flight forward on the night of 31 May/1 June 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 4 June, 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 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, and Lieutenant Mark Townsends's 1 Troop from Kilo Company, 42 Commando had raided the main Argentine positions on Mount Harriet from Goat Ridge. Also, Sergeant Ian Allum's Recce Platoon and other men of the 2nd Scots Guards Battalion completed the mapping out of the Argentinian positions by patrolling from their hide in Port Harriet House. Sadly these successes did not come without loss. On the night of 9-10 June a fighting patrol from Yankee Company stumbled upon a forward mortar camp killing four of the sleeping 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 Y Company the eastern end of Two Sisters.

On 11 June, 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.

==Two Sisters==

X 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 half way 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.
