By 1918, Great Britain was pushed to enact compulsory rationing, after nearly a year on voluntary rationing (since February 1917). To combat misuse and the breaching of ration orders, stiff punishments were also introduced.
As Germany’s unrestricted submarine warfare continued late into the war, the threat to Great Britain’s food supply had continued to mount. In April 1917, the nation’s wheat supply had fallen to just six weeks’ worth (Morrow, The Great War: An Imperial History, p. 202). In the spring of 1918, the British would launch an audacious raid to combat the German submarine threat.
