A HUGE HOLE IN MY LIFE. The story of the Lochnagar Crater on the Somme a talk by the owner, Richard Dunning MBERichard has owned the Lochnagar Crater since 1978.This vast wound on the battlefield is now preserved as a memorial. To those men and women of all nations who fell in the Great War and is dedicated to peace, forgiveness and reconciliation.It is a place of pilgrimage for over 200,000 visitors each year. The Lochnagar mine was an underground explosive charge, secretly planted by the British during the First World War and ready for 1 July 1916, the first day of the Somme, the bloodiest day in British military history. The mine was dug by the Tunneling Companies of the Royal Engineers under a German field fortification known as Schwabenhöhe (Swabian Height) in the front line. The mine was named after Lochnagar Street, the British trench from which the gallery was driven. It was one of 19 mines that were placed beneath the German lines on the British section of the Somme front to assist the infantry advance at the start of the battle. The Lochnagar mine was sprung at 7:28 a.m. on 1 July 1916 and left a crater 98 feet (30 m) deep and 330 feet (100 m) wide, which was captured and held by British troops. The crater is the largest one made in hate by man.
