In addition, the area had been heavily mined. British sappers later counted 1,500 frozen anti-personnel mines on the western lower slopes of Mount Longdon. Miraculously all but two mines failed to detonate.<ref>[https://www.sunderlandecho.com/news/feature-sunderland-falklands-veterans-remember-the-battle-of-mount-longdon-1-4623600 Sunderland Falklands veterans remember the Battle of Mount Longdon]</ref> | On June 10, Lieutenant Colonel Hew Pike gave his orders in the Regimental Headquarters at Estancia House for the attack on Mount Longdon and Wireless Ridge.
