Teesdale's annual Belgium and France World War One battlefields tour took place from the 1-5 July.
Year 9 students visited historic sites across the Western Front including the Tyne Cot memorial, Langemark cemeteries and preserved trenches at Sanctuary Wood, just outside Ypres.
This year, the trip also included a visit to Wellington Quarry under Arras, where soldiers from Britain and New Zealand created a network of tunnels and an underground hospital close to the frontline.
Students travelled deep underground in glass lifts for a guided tour of the tunnels which were marked with messages left by the soldiers one hundred years ago.
The underground hospital that students visited is specifically mentioned in their GCSE specification, focussing on injuries and treatments on the Western Front. Walking through the actual tunnels where casualties were transported to operating theatre really brought this aspect of their course to life.
This was the first time the trip has taken place in July, which allowed the students to see the vibrant flowers at the sites of commemoration and see the poppies that were referenced in John McRae's famous poem 'In Flanders Fields'.
