The film goes straight in to show women using heavy engineering machinery such as belt driven lathes. We see women on the production line assembling shells, which is clearly a complex and quite skilled process. The worker takes great care with the detonator just before weighing the shell.
Context
When the Great War started most people thought it would be a short war. It was soon clear that this was not the case. It would be a long industrial war. The ability to make guns, shells, ships and aircraft would be just as important as the tactics on the battlefield. Britain was soon in need of more workers to fill the gap. By the end of the war around 2 million women workers stepped in to carry out much needed work. They served as clerks, drivers and also worked in engineering and munitions.
Interesting or important points about the film
This clip shows the skill and efficiency of the women workers in the munitions factory. Perhaps the purpose is to boost morale.
