HM Factory, Gretna facts for kids
H. M. Factory, Gretna was Britain's largest cordite factory in World War I. The government-owned facility was adjacent to the Solway Firth, near Gretna, Dumfries and Galloway. It was built by the Ministry of Munitions in response to the Shell Crisis of 1915. The capital cost was £9,184,000 (£445,800,000 in 2024) and it covered 9,000 acres (3,600 ha). The cost of working it from September 1916 to September 1918 was £12,769,000, during which time it produced cordite valued at £15,000,000, though it was claimed that without it the cordite would have had to be imported from the USA at a cost of £23,600,000.
The Devil's Porridge Museum in Eastriggs, Dumfriesshire, commemorates the efforts of these workers during the World War I.
Layout
H. M. Factory, Gretna stretched 9 miles (14 km) from Mossband near Longtown in the east, to Dornock / Eastriggs in the west straddling the Scottish-English border. The facility consisted of four large production sites and two purpose-built townships. The facility had its own independent transport network, power source, and water supply system.
- Site 1, Smalmstown was to the north of Longtown (at 55°00′43″N 2°59′32″W / 55.011953°N 2.992146°W).
- Site 2, Mossband was bounded on the west by the Caledonian Railway (now the West Coast Main Line), and the River Esk on the south and the east (at 54°59′02″N 3°01′26″W / 54.984°N 3.0240°W).
- Site 3, Eastriggs was bounded to the north by the B721 and the Glasgow and South Western Railway, and south by the Solway Firth and the River Sark (at 54°58′35″N 3°10′03″W / 54.976469°N 3.167419°W).
- Site 4, Gretna was contained like Site 3 but it was adjacent to the Gretna township to the east (at 54°59′12″N 3°05′16″W / 54.986675°N 3.087844°W).
A military, 2 ft (610 mm) narrow gauge railway was used to move materials and supplies around the sites. The network, which had 125 miles (201 km) of track, employed 34 engines. Electricity for the munitions manufacture and the townships was provided by a purpose-built coal-fired power station. The telephone exchange was handling up to 2.5 million calls in 1918. The townships had their own bakeries, laundry and a police force. The laundry could clean 6,000 items daily and the bakeries made 14,000 meals a day.
Water was taken from the River Esk, north of Longtown, through a 42 inches (110 cm) diameter pipe to a pump house. From there it was pumped through a 33 inches (84 cm) main to a reservoir. A filtration/treatment works could handle up to ten million gallons (45,000 m3) a day.
History
Construction work on H. M. Factory, Gretna started in November 1915 under the general supervision of S P Pearson & Sons. Up to 10,000 Irish navvies worked on the site as well as concurrently building the two wooden townships to house the workers at Gretna and Eastriggs. To prevent problems with the influx of construction and munition workers, authorities implemented the State Management Scheme which curtailed alcohol sales through the nationalisation of pubs and breweries in the vicinity. Medical issues at the facility were overseen by Thomas Goodall Nasmyth.
Munitions production started in April 1916. Engineers and chemists from nations throughout the British Empire were employed to establish the production of RDB Cordite. By 1917 the largest proportion of the workforce were women: 11,576 women to 5,066 men. The women munitions workers were known collectively as The Gretna Girls.
At its peak, the factories produced 1,400 tonnes of Cordite RDB per week, more than all the other munitions plants in Britain combined. Cordite was colloquially known as the "Devil's Porridge"; the name comes from the writings of Sir Arthur Conan Doyle, who visited H. M. Factory as a war correspondent in 1916. He later wrote "The nitroglycerin on the one side and the gun-cotton on the other are kneaded into a sort of a devil's porridge; which is the next stage of manufacture...those smiling khaki-clad girls who are swirling the stuff round in their hands would be blown to atoms in an instant if certain small changes occurred". In 1917, when production reached 800 tons per week, King George V and Queen Mary visited the factory.
Cordite production ceased shortly after the end of World War I in November 1918. The first 25% redundancies were announced in December 1918, and the final closure notice was issued in August 1919, by which time the workforce had been reduced to 3000 to 4000. In September 1919 the special Andrew Barclay 'fireless' locos used to shunt the explosives were sold off (both 2 foot gauge and standard-gauge) along with 40 standard gauge, covered, bogie 'paste' wagons (made by Magor Car Co. of New York, and Pickering Bros of Wishaw), and a further 86 open 4-wheel contractors wagons. In 1919-20 the manufacturing plants were demolished. Although the entire factory site was retained until the early 1920s, eventually all of Site 4 and other parts of the former munition plant were auctioned off for private and agricultural land. The combined sale consisted of more than 700 lots. The two townships of Eastriggs and Gretna and their bakeries were also sold off.
On its closure, Waltham Abbey Royal Gunpowder Mills near London became the sole government-owned cordite factory until an expansion programme started at the outbreak of World War II.

Later use
Although Site 4 was sold and returned to agricultural use, large parts of the other three sites were retained for ammunition storage by the War Department and later the Ministry of Defence.
Beginning in the 1930s, up to 2,500 acres (1,000 ha) of Site 2, at Mossband, became the Central Ammunition Depot, CAD Longtown. After World War II it became known as Base Ammunition Depot, BAD Longtown. The remaining parts of Site 1, at Smalmstown, were also designated a sub-depot of CAD Longtown.
The Ministry of Supply began using Site 3, to the southeast of Eastriggs, in the 1930s for ammunition storage. The 1,250 acres (506 ha) site was known as CAD Eastriggs. Ammunition was transported from the storage bunkers within CAD Eastriggs using a narrow gauge railway system. Two of the petrol locomotives were used on the Duchal Moor grouse railway near Kilmacolm in Renfrewshire. The site was connected to the Glasgow and South Western Railway at a junction at Eastriggs. In the 1960s, CAD Eastriggs became a sub-depot of CAD Longtown.
The Smalmstown portion of the site closed in 2005, with Eastriggs and Longtown remaining open.
Eastriggs Depot was closed in around 2010, with proposals as of 2021 to repurpose the site as a stabling and maintenance facility for HS2 (High Speed 2) to store up to 28 high speed trains and would be used for cleaning, light maintenance and storage of equipment.
