What was the Western Front battle of World War I combat

The fronts of World War I were divided into the Eastern Front (Russia against Germany and Austria), the Western Front (Britain and France against Germany) and the Southern Front (also known as the Balkan Front, Serbia against Austria-Hungary).

The Western Front of the First World War began as a war of movement and then turned into a war of position, and in September 1914, on the French northeastern border of the Marne River, the Germans were met with a large-scale counterattack by the French in the area, known as the "Battle of the Marne in 1914", and the Germans retreated to the line of the River Ene. The Germans retreated to the Ene River. At this point, positional warfare began to take shape along most of the Western Front. By November, the entire Western Front had shifted from a war of movement to a war of position.

The Eastern Front of the First World War, in 1915, the center of gravity of the war shifted to the Eastern Front, and the Eastern Front also shifted from a war of movement to a war of position. The strategic initiative was still in the hands of the Allies, but the war potential of the Allies was mobilizing. Britain and France basically shifted to strategic defense on the Western Front in order to build up their strength; at the same time, Russia was asked to intensify her offensive on the Eastern Front. Germany changed its strategic direction, trying to defeat Russia, the weak link of the Allies, as soon as possible, and then defeat Britain and France, so it also basically shifted to strategic defense on the Western Front, while attacking aggressively on the Eastern Front. in May, Italy, a former member of the Allies, declared war on Austria-Hungary, and opened a new theater of war to the south-east of Austria-Hungary. in September-October, the entire Eastern Front also shifted from movement warfare to positional warfare.

The southern front battlefield of the First World War (i.e., the Balkan Front), where the Austrian army fought with the Serbian army, also became the outbreak of the First World War. In the Balkan Wars, the increase in the range and speed of artillery, the increase in the number of machine guns, the use of aircraft for bombing in addition to aerial reconnaissance, and the extensive use of military technology such as armored vehicles and radios prompted the army to switch to sparse battle formations, using ground folds and trenches for concealment, while also having to protect troops from air attack; the army spread out over hundreds of kilometers of the front line. The increased intensity of defenses, in turn, made maneuver warfare more difficult. The tendency to transition to positional warfare as a style of combat became more pronounced. These have had a significant impact on subsequent wars.
