Some historians of World War One have stated that any tour of the Battle of the Somme area should start with the Lochnagar Crater. It is a massive crater one hundred metres (328 feet) in diameter and 30 metres (98 feet) deep. Why on earth was it made or rather, how on earth was it made? The Lochnagar Crater was created by the British, when two batches of explosive, 16 metres deep and 20 metres apart, went up at 7.28 am on July 1st. It was hoped that loads of the enemy near La Boiselle, would be killed and others would be stunned and not know what was going on. This, along with another eighteen mines, was the signal for men to “go over the top”, ie get out of their trench, make their way through the already cut barbed wire protection and then run at the enemy.
