It has been confirmed that 70No. Self-Igniting Phosphorus (SIP) grenades were found during recent improvement works at Tongland Dam in Dumfries & Galloway.
The devices, a favoured weapon of the Home Guard during WWII, are glass bottles filled with a crude mixture of white phosphorus and benzene, a filling extremely sensitive when exposed to air. They were designed to be deployed as an emergency anti-tank device when the threat of a German invasion loomed large early in the war.
After a 100m exclusion zone was put in place and three homes evacuated, an Explosive Ordnance Disposal (EOD) team arrived to carry out a controlled explosion.
