Here we see lunch being prepared in a World War II Field Kitchen.
The first cooker adopted by the British Army after demonstrations of the prototypes by Alex Soyer to the British Army in Crimea. They have been used continually until the 1980's when the vast majority of the British Army stock was lost in the sinking of the Atlantic Conveyor during the Falklands War.
Capable of boiling 12 gallons of liquid using any available solid fuel they are simple and efficient. The original specification was that two, together with wood for fuel could be carried by a mule.
The Soyer was adopted as standard by the Civil Defence organisation during World War II and examples staffed by the Woman’s Voluntary Service were used to provide emergency food in the bombed areas during the Blitz. After World War II large numbers were put into storage in the event of a nuclear attack.
