THE Lord Mayor of Bradford has invited people to remember the sacrifice made by the Bradford Pals.
A service is planned for Tuesday at 11am at the Bradford Pals' Memorial Stone, next to the city's war memorial.
There will be prayers by the Lord Mayor's Chaplain, Father Philip Gray, and reflections by the Dean of Bradford, The Very Reverend Jerry Lepine.
There will be contributions from the Bradford World War I Group and The Great War Society.
The Lord Mayor of Bradford Councillor Mike Gibbons said: "This service is always very important for the people of Bradford to remember the sacrifice that was made and the heavy losses sustained on that day and remember all local men who lost their lives serving in their country during the whole of the First World War."
The Bradford Pals formed part of the West Yorkshire Regiment and on July 1, 1916 they took part in an attack around the village of Serre in Northern France.
By the end of the first hour of the battle, more than 1,700 men from Bradford had been killed or injured.
