Fun fact: Bovril was created by a British company, at the request of the French Emperor Napoleon III, during the Franco-Prussian war.
It was known as "Fluid Beef" and was for distribution to French troops.
Unsurprisingly, they rebranded it pretty fast.
World War One advert for Bovril, in which a patriotic cow offers to be boiled down and sent down to France.
The beef-extract was consistently marketed as a drink for soldiers. Members of the public were encouraged to send Bovril to the front line to support the forces.
Seems only fair to remind everyone of this, too.
