The existance of Eastriggs is very much related to World War I. The Township of Eastriggs was created as a result of the shell and ammunition crisis of June 1915 which prompted the newly-founded Ministry of Munitions to create a new cordite-manufacturing facility. Like gunpowder, cordite is a low explosive. After the failure of the Battle of Neuve Chapelle in March 1915, the British Commander-in-Chief Field Marshal Sir John French mentioned to The Times war correspondent, Colonel Charles à Court Repington, that it failed due to a lack of shells. The Shell Scandal was reported back to the Home. So a facttory was created.
The factory was spread over a 14.4 km site stretching from Dornock through Gretna to Longtown, Cumbria. This required a huge influx of labour, and 30,000 men and women came from all over the British Commonwealth to serve as construction and factory workers. Wooden housing for the workers was created in both Eastriggs and Gretna.
