German Army (German Empire) in the context of "British Army during the First World War"

The Schlieffen Plan (German: Schlieffen-Plan, pronounced [ʃliːfən plaːn]) is a name given after the First World War to German war plans, due to the influence of Field Marshal Alfred von Schlieffen and his thinking on an invasion of France and Belgium, which began on 4 August 1914. Schlieffen was Chief of the General Staff of the German Army from 1891 to 1906. In 1905 and 1906, Schlieffen devised an army deployment plan for a decisive (war-winning) offensive against France. German forces were to invade France through the Netherlands, Luxembourg and Belgium rather than across the common border.

After losing the First World War, the German official historians of the Reichsarchiv and other writers, described the plan as a blueprint for victory. Generaloberst (Colonel-General) Helmuth von Moltke the Younger had succeeded Schlieffen as Chief of the German General Staff in 1906 and was dismissed after the First Battle of the Marne (5–12 September 1914). German historians claimed that Moltke had ruined the plan by tampering with it, out of timidity. They managed to establish a narrative that Moltke failed to follow the blueprint devised by Schlieffen, condemning the belligerents to four years of attrition warfare.

The First Battle of the Marne or known in France as the Miracle on the Marne (French: miracle de la Marne) was a battle of the First World War fought from 5 to 12 September 1914. The German army invaded France with a plan for winning the war in 40 days by occupying Paris and destroying the French and British armies. The Germans had initial successes in August. They were victorious in the Battles of Mons and the Frontiers and overran a large area of northern France and Belgium. In what is called the Great Retreat the Germans pursued the retreating French and British forces more than 250 km (160 mi) southwards. The French and British halted their retreat in the Marne River valley, while the Germans advanced to 40 km (25 miles) from Paris.

With the battlefield reverses of August, Field Marshal John French, commander of the British Expeditionary Force (BEF), lost faith in the French and began to plan for a British retreat to port cities on the English Channel for an evacuation to Britain. Joseph Joffre, the French commander, maintained good order in his retreating army and was able to reinforce it with troops from his eastern flank and by integrating military reserve units into the regular army. By early September, the Franco–British forces outnumbered the Germans, who were exhausted after a month-long campaign, had outrun their supply lines and were suffering shortages. On 3 September, the military governor of Paris, Joseph Gallieni, perceived that the German right flank was vulnerable and positioned his forces to attack.

The 5th Army (German: 5. Armee / Armeeoberkommando 5 / A.O.K. 5) was a field army of the Imperial German Army during World War I. It was formed on mobilization in August 1914 seemingly from the VII Army Inspection. The army was disbanded in 1919 during demobilization after the war.

The Second Battle of Champagne (French: Bataille de Champagne, German: Herbstschlacht, [Autumn Battle]) in the First World War was a French offensive against the German army in Champagne that coincided with the Third Battle of Artois in the north and ended in a German victory.

The Supreme Commander of All German Forces in the East (German: Oberbefehlshaber der gesamten Deutschen Streitkräfte im Osten), also known by its German abbreviation as Ober Ost, was both a high-ranking position in the armed forces of the German Empire as well as the name given to the occupied territories on the German section of the Eastern Front of World War I, with the exception of Poland. It encompassed the former Russian governorates of Courland, Grodno, Vilna, Kovno and Suwałki. It was governed in succession by Paul von Hindenburg and Prince Leopold of Bavaria. It was abandoned after the end of World War I.

Rudolf Walter Richard Hess (Heß in German; 26 April 1894 – 17 August 1987) was a German politician, convicted war criminal and a leading member of the Nazi Party in Germany. Appointed Deputy Führer (Stellvertreter des Führers) to Adolf Hitler in 1933, Hess held that position until 1941, when he flew solo to Scotland in an attempt to negotiate the United Kingdom's exit from the Second World War. He was taken prisoner and eventually convicted of crimes against peace. He was still serving his life sentence at the time of his suicide in 1987.

Hess enlisted as an infantryman in the Imperial German Army at the outbreak of World War I. He was wounded several times during the war and was awarded the Iron Cross, 2nd Class, in 1915. Shortly before the war ended, he enrolled to train as an aviator, but he saw no action in that role. He left the armed forces in December 1918 with the rank of Leutnant der Reserve. In 1919, he enrolled in the University of Munich, where he studied geopolitics under Karl Haushofer, a proponent of the concept of Lebensraum ('living space'), which became one of the pillars of Nazi ideology. He joined the Nazi Party on 1 July 1920 and was at Hitler's side on 8 November 1923 for the Beer Hall Putsch, a failed Nazi attempt to seize control of the government of Bavaria. While serving a prison sentence for this attempted coup, he assisted Hitler with Mein Kampf, which became a foundation of the political platform of the Nazi Party.

The Finnish Civil War was a civil war in Finland in 1918 fought for the leadership and control of the country between White Finland and the Finnish Socialist Workers' Republic (Red Finland) during the country's transition from a grand duchy ruled by the Russian Empire to a fully independent state. The clashes took place in the context of the national, political, and social turmoil caused by World War I (Eastern Front) in Europe. The war was fought between the paramilitary Red Guards, led by a section of the Social Democratic Party with backup of the Russian bolsheviks and the paramilitary White Guards of the senate. General C. G. E. Mannerheim led the White Guards with major assistance by both the Finnish Jäger Battalion trained in Germany and the German Imperial Army, along the German goal to control Fennoscandia and Petrograd of Russia. The Reds composed of industrial and agrarian working class people controlled the cities and industrial centres of southern Finland. The Whites composed of land owners and the middle and upper class people controlled the rural central and northern Finland.

In the years before the conflict, Finland had experienced rapid population growth, industrialisation, gradually increasing urbanisation and the rise of a comprehensive labour movement. The country's political and governmental systems were in an unstable phase of democratisation and modernisation. The socio-economic condition and education of the population had gradually improved, and national awareness and culture had progressed. World War I led to the collapse of the Russian Empire, causing a power vacuum in Finland, and the subsequent struggle for dominance led to militarisation and an escalating crisis between the left-leaning labour movement and the conservatives.

The Imperial German General Government of Belgium (German: Kaiserliches Deutsches Generalgouvernement Belgien) was a German Army occupation administration which administered one of the three separate occupation zones established in German-occupied Belgium during the First World War.

The Battle of Belleau Wood (1–26 June 1918) was a major battle that occurred during the German spring offensive in World War I, near the Marne River in France. The battle was fought by the U.S. 2nd (under the command of Major General Omar Bundy) and 3rd Divisions along with French and British forces against an assortment of German units including elements from the 237th, 10th, 197th, 87th, and 28th Divisions.

In United States Marines Corps lore dating back to the battle, the nickname Teufel Hunden (Devil Dogs) was given to the Marines by German troops. The battle has become a key component of Marine Corps history.
