With troops like these, you can ask them to do the impossible… which is just what the War Office did with Major Alec Barber and his unit, when they sent them behind enemy lines to recover part of a secret formula for an amazing weapon, that could end the war in a day.

And that formula was inside the crater of Mount Etna —the biggest volcano in Europe.
