The Battle of the Somme took place 1 July-November 18, 1916, on both sides of the upper reaches of the River Somme in France.
More than a million men were wounded or killed, making it one of the bloodiest battles history.
The first day was one of the blackest in British military history, with 60,000 casualties. Some 20,000 men died.
The Bailiff Bridge service will take place Friday July 1 at 11am.
Organisers have suggested anyone who wishes to attend to arrive by 10.45am.
