In this episode we travel from the Yorkshire Moors to the Somme battlefield at Serre to discover the story of the Leeds Pals. Who were these men? Why is their training ground now a special place for them? We look at the extraordinary bravery of their young Officers and Other Ranks on the first day of this infamous battle, and read a letter written by the sister of a 16 year old Boy Soldier, begging him to return home. In amongst the Officers who fell that die, we tell the story of 2 successful sportsmen. And we discover what happened when the Pals returned to Serre in 1935.
