A sunken road is a road or track which is deeper than the land on either side. The sunken roads were heavily usedfor agricultural and it could have been the farmer who constantly dug and cleared the roads that pushed up the soil banks around the roads. Other theories for how the roads were formed include erosion by water and the digging of double banks to mark the boundaries of estates.
These roads become crucial for the troops of all sides during the warfare of the First World War. They provided cover for the men and allowed for shelter on long marches. They became the scenes for many battles and the roads were witness to large numbers of causalities.
The Craters near La Boisselle and Beaumont-Hamel are well documented but only two remain in evidence today. The large crater called Y-Sap was filled in when farmers wanted to reclaim the field. The bigest crater at La Boisselle is now called the Lochnagar Crater. On the 1st July 1978 Richard Dunning was handed the 'deeds' to the Lochnagar Crater in an informal ceremony at the site. Interestingly, in 1972 Mr Dunning was reading John Masefield’s, The Old Front line when he must have had an epiphany and decided he wanted to own a bit of the Somme Battlefield.
The crater gets its name because in 1915, when the British troops took over the trenches from the French Army at La Boisselle, there was a battalion called the 7th Gordon’s, formed mainly from Deeside. An officer went round naming all the trenches after familiar landmarks and towns. Lochnagar was the name of the mountain not far from Balmoral.
