The 3rd Company of the 4th Infantry Regiment suffered violent attacks, rejecting again and again the enemy's attacks. Argentine machine guns and mortars kept the British at bay, who, protected by darkness, tried to climb the slopes. After hours of fighting, the ammunition began to become scarce and the "6th Infantry" retreated fighting, while the British seized Mount "Two Sisters" north. From there, the "4th Infantry" was attacked, which, faced with the risk of being surrounded, retreated in an orderly battle towards Tumbledown, joining the forces of the 5th Marine Infantry Battalion that controlled those heights. The 5th Marine Infantry Battalion was the one that withstood the British attacks in the combats by the Tumbledown mount. The British advanced with three columns and climbed the mountain to the north, launching an assault on the 5th Section of the Battalion. Later, a company of Scots Guards attacked the 4th Section of the "Nacar" Company. The day before, the British had entered a minefield, leaving several of their personnel wounded. When the 5th Section of the battalion could not withstand the British attacks, it had to retreat leaving an unprotected platoon of the 4th Infantry Regiment, which fought side by side with the Marines. Under the crossfire of the British machine guns, the squad leader, second lieutenant Oscar Augusto Silva and five of his soldiers lost their lives. By 9:00 a.m., the Scots Guards had gained the high ground east of Tumbledown Mountain and the Gurkhas commenced deploying across the heavily shelled saddle from Tumbledown south to Mount William, which they took with the loss of 8 wounded. The 2nd Battalion Scots Guards had lost eight dead and 43 wounded. The Welsh Guards had lost one dead, the Royal Engineers had also lost one dead, and the Gurkhas had sustained altogether 13 wounded, including the artillery observation officer, Captain Keith Swinton. The Scots Guards took 30 prisoners, several of them RI 6 soldiers from Bravo Company. The bodies of 30 Argentine Army and Marine soldiers were found in and around the 5th Marine Battalion perimeter. Reaching the rear positions of N Marine Company, Second Lieutenant Franco took the time to set free several German Shepherds left behind in the Argentine retreat from Tumbledown. The troops of the 4th Infantry Regiment under the command of Lieutenant Colonel Soria, prepared to face the troops of 42 British Commandos, which, after breaking through a minefield, unleashed a violent attack from the West on the 1st Company of the 4th Infantry Regiment and then from the North, on the 2nd Company also of the "4 Infantry" which was reinforced by the 1st "B" section of the 12th Infantry Regiment.
