The Post Office in the First World War

The British Post Office in the First World War.  They have a museum with a section on their role.

The breakout of war across the world posed a massive challenge for the postal system that not only had to maintain a service at home but was now also having to provide a service to ever changing theatres of war around the world and at sea. The British Post Office not only had to rise to this massive challenge, but had to do so with reduced numbers of staff. The organisation sent thousands of men off to fight in the war and also to help run the postal service at the front lines. Many of these men were to never return home. Women were employed in huge numbers to fill the gaps left by men. The Post Office were to lead the way in providing employment for women that was to go on after the war to help in the cause of women’s suffrage.
