The attack by the Scots Guards soon bogged down when Left Flank hit a virtual wall of lead as they moved off their start positions and attempted to storm the crags. Pinned down by snipers it took hours for the battalion to eventually get enough mortars and artillery registered on the more obstinate positions.
Once the company started to go forward it developed into a 2 pronged attack.
In this video clip Ian Davidson is describing how the left hand of the prong advanced across the North Face of Tumbledown. It was the clearing of these positions that unhinged the defence on Tumbledown and perpetrated the collapse of the defence line.
Most of the Argentine positions were on the South slope facing the Stanley road leaving a platoon of engineers to cover the North slope which faced Mount Longdon. It was these positions that were cleared leaving the Scots Guards free to climb up into the crags and fire onto the back and flank of the main Argentine defences the other side.
Scaling these crags in the dark, during a snow storm, under fire, heavily laden with ammunition and carrying ammunition was quite a feat in itself. Upon reaching the top the 66 rocket was used to great effect as a "bunker buster" and the effects on morale of defenders as they slammed into positions was very disconcerting. The 66 was single use weapon and once used the empty tube was tossed away. These have laid on the ground where they landed eversince.
