The 1918 influenza pandemic was a deadly influenza pandemic that infected 500 million people around the world.
Some 3 to 5% of the Earth's entire population at the time died.
The German March Offensive in 1918 took place in the middle of the pandemic and the loss of soldiers to flu weakened the German attack.
On the British side it weakened the defence.
Jane Orr will explain the epidemiology of the pandemic and discuss its effect on the progress of the war effort in 1918, especially from the German point of view.
