　　In World War I, on July 31, 1917, German soldiers sniped every single French soldier that attacked them. The Germans hid in shell holes, waiting and sniping at the French infantrymen who were coming in orderly columns.On the battlefield, where the battle scars remain, we can see another inhuman and horrifying murder of a battle of positions. French troops attacked German dugouts. François Paul Antoine, commander of the French First Army, was defending the northern flank of the British Army across the Ypres Canal during the Third Battle of Ypres. The French attack began on July 31, 1917. The French were stopped by the German Fifth Army led by Max von Gulwitz.

　　Against German positions almost completely leveled by French barrage, the assault of the French First Army, led by General François Paul Antoine, failed at the Third Battle of Flanders. The Third Battle of Ypres (also known as Passchendaele), fought between July and November 1917, was disastrous, with heavy casualties on both sides, and in 1917, British General Douglas Haig planned a major offensive to break through the Ypres Gorge, which the Allies had occupied since 1914. He planned to occupy the highlands around Ypres and an important railroad junction to the east, and to advance on a German-occupied port on the Belgian coast that was crucial to the U-boat campaign. The battle lasted more than 100 days, during which time the Allied forces advanced about 8 kilometers, inflicting more than 250,000 casualties and missing persons.

　　　The Western Front of World War I became a stalemate of trench warfare. Trench warfare on the Western Front was an endless battle of mud and shells against the enemy. Trenches were constructed by digging holes to avoid bullets and shells in plain battle, reinforcing them with sandbags and timber, and laying planks underfoot. New weapons such as poison gas and tanks were introduced to break up the stalemate of trench warfare. Trenches are trenches dug by human or mechanical power to protect against enemy bullet fire in battles fought on relatively level ground. The battle lines were at a stalemate, and each advance cost the lives of soldiers on the scale of thousands.
