This week we return to the Somme battlefields to discover what happened to the Northumberland Fusiliers on 1st July 1916 on their first day in battle. We tell the story with help from Martin Talbot, who has researched their story, and through the eyes of Captain James Bibby who led his men into action on that day. We also hear from Bibby's Great, Great Grandsons who walked the battlefields with me last month. They are just 9 and 11 years old and give a different prospective to the battle. What did they find on their tour and how has it affected them.
