German U-Boat attacks on convoys supplying Britain resulted in a shortage of food. By April 1916 Britain was said to have only enough wheat left to last how long?

The First World War had a huge impact on British society.  Millions of men left their ordinary lives to fight for king and country.  But life changed too for those they left behind.  A shortage of manpower meant that women had to replace the absent men.  Many parts of British life were put on hold for the duration of the war and others were gone forever.
