The battle that changed Ireland

1st July, 1916 is still one of the bloodiest days in the history of war. Nearly 20,000 men from the British Army died on the first day of the Battle of the Somme. One of the first examples of industrial warfare, the offensive would go on for over four months and cause over a million casualties on both sides. The documentary uncovers how the battle still affects people and communities; and discovers new insights about Jordan's own family history.
