In 1914, Achiet-le-grand had a population of about 500 people.

The village was a bustling hub thanks to its active train station and the weekly veal market, held every Saturday, where up to 300 calves were put up for sale. However, on the 2nd of August 1914, the rhythm of daily life was abruptly shattered as the residents of Achiet heard the ominous declaration of war.

As men journeyed by train to enlist, they frequently stopped at Achiet, where villagers offered vital comfort and supplies to boost their morale. British troops arrived during the opening fortnight of August before pressing onward. By August 27th, Achiet-le-Grand found itself caught directly between rival German and French patrols.

On September 18th, a large force of German troops arrived, and their colonel established his headquarters at the Château de Tourtois in Bihucourt. Meanwhile, French soldiers withdrew to set up camp in Logeast Wood, holding their position until fighting finally erupted on October 3rd.

The staggering casualties between Achiet and Courcelles forced local citizens to bury the dead. Meanwhile, males aged 14 to 50 were deported to forced labor camps in Germany, leaving the women behind to manage all daily responsibilities.

Each year, on the Sunday closest to October 3rd, a solemn remembrance day is held at Courcelles-le-Comte.
