Chris and Sam Ogrizovic are embarking on the 1,500 mile journey without using a map and with just £20 in their pocket - the same as their grandfather Nicola did in 1942. Brave Nicola Ogrizovic grew up in the small village called Brlog in Croatia with his parents and two sisters. But he was forced to flee the Nazis in 1942 aged just 14 when German soldiers brutally murdered his father in front of him.
