So on Thursday we found some suspected unexploded ordnance in the tunnel, a phone call to Stuart (Ordinance Disposal Officer) at police hq and he popped down to assess. What we had found were plugs or caps that are put in to the end of drill holes, the holes would have been filled with nitroglycerin. Our suspicion became increased when we noticed small wires coming out the side. Luckily for us the holes were dry and not packed. Stuart told us he was responsible for clearing a similar setup in Ho8 (Jersey War Tunnels) and many of the holes there were still packed with nitroglycerin! All plugs were safely removed from Ho19 that night with Kimberley and I learning an awful lot while helping Stuart do his thing.
A massive thanks goes out to the Explosive Ordinance Disposal Officer Stuart Elliot of the States of Jersey Police. WWII Sites in Jersey always have the risk of unexploded ordinance being found, if you find or see anything suspicious please contact the police on 01534 612612. They have a page on what to do here.
