Here's it's August 1914, just after war began. Passengers and crew of German liners in Falmouth harbour at that time were rounded up by the army, and initially interned in Cornish workhouses.
Under armed guard, the foreign civilians - by no means all German nationals - are being marched up Redruth's Station Hill. They've been detained in nearby Barncoose workhouse, but are about to be sent by train to Devonport. From there, some will be allowed to travel home; others, defined as enemy aliens, will enter long-term internment.
