Schlieffen Plan

Helmuth Karl Bernhard Graf von Moltke (26 October 1800, Parchim, Mecklenburg-Schwerin – 24 April 1891, Berlin) was a German Field Marshal.
 The chief of staff of the Prussian Army for thirty years, he is regarded as the creator of a new, more modern method of directing armies in the field.
 He is often referred to as Moltke the Elder to distinguish him from his nephew Helmuth Johann Ludwig von Moltke, who commanded the German Army at the outbreak of World War I.
The Kreisau Circle (German: "Kreisauer Kreis") (1940–1944) was a group of about twenty-five German dissidents led by Helmuth James Graf von Moltke, who met at his estate in the rural town of Kreisau, Silesia.
 The circle was composed of men and a few women from a variety of backgrounds, including those of noble descent, devout Protestants and Catholics, professionals, socialists, and conservatives.
 Despite their differences, the members of the Kreisau Circle found common interest in their opposition to Hitler's Nazi regime on both moral and religious grounds.
 At their meetings, the circle discussed how they would reorganize the German government after the end of the Third Reich.
 Although the circle did not promote violent overthrow of the regime, their planning was considered by the Nazis to be treasonous as it rested on the assumption that Germany would lose the war.
 The group began to falter after Helmuth von Moltke was arrested by the Gestapo in January 1944 and eventually came to an end when most of its members were arrested following Claus von Stauffenberg's attempt on Hitler's life on July 20, 1944.
SMS "Moltke"  was the lead ship of the "Moltke"-class battlecruiser s of the German Imperial Navy, named after the 19th-century German Field Marshal Helmuth von Moltke.
 Commissioned on 30 September 1911, the ship was the second battlecruiser commissioned into the Imperial Navy.
Moltke Bridge is a bridge over the Spree River in Berlin, Germany.
 Completed in 1891, it connects Alt-Moabit near the main railway station on the north bank to Willy-Brandt-Straße and the Chancellery on the south bank.
 The bridge is named after Field Marshal Helmuth von Moltke the Elder (1800–1891), chief of staff of the Prussian Army for thirty years.
 Moltke died just before the bridge's completion and it was inaugurated by his funeral cortege.
 The bridge has three crossed arches spanning the Spree made from red Main sandstone, decorated with statues of Johannes Boesen, Carl Piper and Carl Begas.
Alfred Graf von Schlieffen, mostly called Count Schlieffen (] ; 28 February 1833 – 4 January 1913) was a German field marshal and strategist who served as Chief of the Imperial German General Staff from 1891 to 1906.
 His name lived on in the 1905–06 'Schlieffen Plan', then "Aufmarsch I", a deployment plan and operational guide for a decisive initial offensive operation/campaign in a one-front war against the French Third Republic.
Helmuth Johann Ludwig von Moltke (] ; 23 May 1848 – 18 June 1916), also known as Moltke the Younger, was a nephew of "Generalfeldmarschall" (Field Marshal) Helmuth Karl Bernhard von Moltke and served as the Chief of the German General Staff from 1906 to 1914.
 The two are often differentiated as "Moltke the Elder" and "Moltke the Younger".
The Battle of the Frontiers was a series of battles fought along the eastern frontier of France and in southern Belgium shortly after the outbreak of World War I.
 The battles resolved the military strategies of the French Chief of Staff General Joseph Joffre with Plan XVII and an offensive interpretation of the German "Aufmarsch II" deployment plan by Helmuth von Moltke the Younger.
 The German concentration on the right (northern) flank, to wheel through Belgium and attack the French in the rear, was delayed by the movement of General Charles Lanrezac's Fifth Army towards the north-west to intercept them and the presence of the British Expeditionary Force (BEF) on his left flank.
 The Franco-British were driven back by the Germans, who were able to invade northern France.
 French and British rearguard actions delayed the German advance, allowing the French time to transfer their forces to the west to defend Paris, resulting in the First Battle of the Marne.
The Moltke Nunataks ( ) are a chain of north–south trending nunataks close to the northeastern end of the Filchner Ice Shelf, Antarctica.
 One nunatak was first roughly mapped and named "Moltke Nunatak" by the Second German Antarctic Expedition of 1911–12 under Wilhelm Filchner.
 He named it for General Helmuth von Moltke, Chief of the German General Staff and Secretary of State for Home Affairs.
 Surveys during the mid-1950s by British, Argentine and United States expeditions indicate that a group of four or five nunataks exist in the area.
SMS "Moltke" was a "Bismarck"-class corvette built for the German Imperial Navy ("Kaiserliche Marine") in the late 1870s.
 The ship was named after Prussian Field Marshal Helmuth von Moltke the Elder and served as training vessel for cadets and midshipmen and made numerous voyages abroad.
The Schlieffen Plan (German: "Schlieffen-Plan" , ] ) was the name given after World War I to the thinking behind the German invasion of France and Belgium on 4 August 1914.
 Field Marshal Alfred von Schlieffen, the Chief of the Imperial Army German General Staff from 1891 to 1906, devised a deployment plan for a war-winning offensive, in a one-front war against the French Third Republic from 1905–06.
 After the war, the German official historians of the "Reichsarchiv" and other writers, described the plan as a blueprint for victory.
 German historians claimed that the plan had been ruined by "Generaloberst" (Colonel-General) Helmuth von Moltke the Younger, the Commander-in-Chief of the German army after Schlieffen retired in 1906, who was dismissed after the First Battle of the Marne (5–12 September 1914).
