Being very close to the front line during much of World War I 1914–1918, the town was all but destroyed. Every building, as well as the cemetery, suffered a great deal of damage. The German attack of 21 March 1918 on the front line from Saint-Quentin to La Fère had succeeded in creating a pocket 80 kilometres (50 mi) deep into the combined British and French lines. General Seely set up his headquarters at Berteaucourt-lès-Thennes in March, 1918. On 8 August 1918 the French troops left Thennes and Berteaucourt-lès-Thennes, counter-attacking towards Villers-aux-Érables.
