Bombardier Ronald and Private Ernest Cavalier

S1, E3: Gallipoli is Australia's most commemorated battleground, etched deeply into the national psyche. It's also woven deeply into Josh Cavalier's family story: both his grandfather and great grandfather fought among those unforgiving beaches and cliffs. Incredibly, father and son survived the First World War but for generations, combat has left a lasting legacy on the Cavalier men. And it lingers to this day. Now, as Josh, a 30-year-old IT technician, embarks on this journey, he quickly discovers it will be full of surprises. This is a tender story about the relationship between a father and a son - and the need to understand the past in order to look to the future.
