When Russian forces invaded Ukraine in February, one of their first targets was the city of Mariupol. The battle that followed is an epic story of resistance in which a very small number of Ukrainian fighters defended the city for over eighty days against a Russian force five to eight times their size, preventing the Russians from diverting to other parts of Ukraine. In this episode, John Spencer is joined by Aiden Aslin, a British citizen who took part in that battle and was captured by Russian forces there in April 2022. His experiences offers a unique view of how the Battle of Mariupol unfolded, and the details of his captivity as a Russian prison of war for over five months offer a glimpse into an often unseen aspect of the war.
