During the Battle of the Somme on the Western Front of World War I, the bodies of many German soldiers were scattered in the shell holes between Carnoy and Montauban, the southernmost point of the British 4th Army's assault front.

　　On the Western Front of World War I, during the Battle of the Somme, the British 4th Army's assault front caused many German soldiers to be scattered dead in the shell holes between the southernmost Carnoy and Montauban. On July 1st 1916, the first day of the Battle of the Somme, the British army's assault on Montauban broke out.When shells hit the trenches, more than ten soldiers were killed or wounded instantly. The bodies were left unburied, and even if they were buried, they were dug up again in later battles. The soldiers spent weeks at a time near the bodies. During the Battle of the Somme, the soldiers were repeatedly confronted with scenes of mass killing.

　The British army was equipped with a huge amount of artillery shells to destroy the German positions. They lined up heavy artillery and mortars at intervals of less than 60 meters over a distance of 24 kilometers, and also prepared field artillery to destroy the barbed wire. In battles at the time, infantry would advance after artillery bombardment to mop up the enemy. The width of the attacking front was made wider than before so that the advancing troops in the center of the breakthrough would not be fired on from the flanks. However, the British army did not have the artillery and shells that could overwhelm the enemy's defensive forces on the front of the attack. It was difficult to create gaps through which the infantry could pass by simply scattering the barbed wire with artillery shells. The gaps between the barbed wire were too narrow, and the British attack units themselves had to clear the barbed wire, which became a serious obstacle to their advance.

　　The British attack infantry units were required to advance as quickly as possible while repeatedly firing and moving. The troops would advance a short distance, then lie down on the ground or hide behind cover to fire their weapons and provide cover for other troops advancing behind them. During the Battle of the Somme, British troops advanced in single file, shoulder to shoulder, at a slow walking pace. The Germans, who had occupied the high ground across the entire front line, were in a favorable position and strengthened their defensive posture against the Allied offensive. When the shelling stopped, the Germans crawled out of the underground shelters they had dug to a depth of 9 meters, set up their machine guns in position and opened fire, and the British attack troops, who were advancing at a slow pace, were stuck in place.
