Question: Where was the initial German offensive on the conflict Henry Ralph Lumley fought in stopped in September 1914?

full_context: Document 1: William Lumley: General Sir William Lumley, (28 August 1769 – 15 December 1850) was a British Army officer and courtier during the late eighteenth and early nineteenth centuries. The son of the Earl of Scarborough, Lumley enjoyed a rapid rise through the ranks aided by a reputation for bravery and professionalism established on campaign in Ireland, Egypt, South Africa, South America, Italy, Portugal and Spain. Following his retirement from the army due to ill health in 1811, Lumley served as Governor of Bermuda and later gained a position as a courtier to the Royal Household. Lumley is especially noted for his actions at the Battle of Antrim where he saved the lives of several magistrates and was seriously wounded fighting hand-to-hand with United Irish rebels in the Irish Rebellion of 1798.
Document 2: Hubert Latham: Arthur Charles Hubert Latham (10 January 1883 – 25 June 1912) was a French aviation pioneer. He was the first person to attempt to cross the English Channel in an aeroplane. Due to engine failure during his first of two attempts to cross the Channel, he became the first person to land an aeroplane on a body of water.
Document 3: Modern history: Much of the fighting in World War I took place along the Western Front, within a system of opposing manned trenches and fortifications (separated by a "No man's land") running from the North Sea to the border of Switzerland. On the Eastern Front, the vast eastern plains and limited rail network prevented a trench warfare stalemate from developing, although the scale of the conflict was just as large. Hostilities also occurred on and under the sea and—for the first time—from the air. More than 9 million soldiers died on the various battlefields, and nearly that many more in the participating countries' home fronts on account of food shortages and genocide committed under the cover of various civil wars and internal conflicts. Notably, more people died of the worldwide influenza outbreak at the end of the war and shortly after than died in the hostilities. The unsanitary conditions engendered by the war, severe overcrowding in barracks, wartime propaganda interfering with public health warnings, and migration of so many soldiers around the world helped the outbreak become a pandemic.
Document 4: Hans Imelmann: Leutnant Hans Imelmann IC was a World War I flying ace credited with six aerial victories. As a founding member of one of Germany's original fighter squadrons, he was shot down and killed before he reached his twentieth birthday.
Document 5: Western Front (World War I): The German Army came within 70 km (43 mi) of Paris but at the First Battle of the Marne (6 -- 12 September), French and British troops were able to force a German retreat by exploiting a gap which appeared between the 1st and 2nd Armies, ending the German advance into France. The German Army retreated north of the Aisne River and dug in there, establishing the beginnings of a static western front that was to last for the next three years. Following this German retirement, the opposing forces made reciprocal outflanking manoeuvres, known as the Race for the Sea and quickly extended their trench systems from the Swiss frontier to the North Sea. The territory occupied by Germany held 64 percent of French pig - iron production, 24 percent of its steel manufacturing and 40 percent of the coal industry -- dealing a serious blow to French industry.
Document 6: British Expeditionary Force (World War II): The BEF (General Lord Gort) began moving to France in September 1939. The British assembled along the Belgian -- French border on the left of the French First Army as part of the French 1er groupe d'armées (1st Army Group) of the Front du Nord - est (North - Eastern Front). Most of the BEF spent the Phoney War digging field defences on the French -- Belgian border, before the Battle of France (Fall Gelb) began on 10 May 1940. The BEF constituted 10 percent of the Allied forces on the Western Front. The BEF participated in the Dyle Plan, a rapid advance into Belgium to the line of the river Dyle but had to retreat through Belgium and north - western France with the rest of the 1er groupe d'armées, after the German breakthrough further south at the Battle of Sedan. The BEF, French and Belgian forces cut off north of the Somme river were evacuated from the French North Sea coast through port and beaches of Dunkirk in Operation Dynamo.
Document 7: Franco-Prussian War: On 10 October, hostilities began between German and French republican forces near Orléans. At first, the Germans were victorious but the French drew reinforcements and defeated the Germans at the Battle of Coulmiers on 9 November. After the surrender of Metz, more than 100,000 well-trained and experienced German troops joined the German 'Southern Army'. The French were forced to abandon Orléans on 4 December, and were finally defeated at the Battle of Le Mans (10–12 January). A second French army which operated north of Paris was turned back at the Battle of Amiens (27 November), the Battle of Bapaume (3 January 1871) and the Battle of St. Quentin (13 January).
Document 8: Maginot Line: The Maginot Line was impervious to most forms of attack, including aerial bombings and tank fire, and had underground railways as a backup; it also had state - of - the - art living conditions for garrisoned troops, supplying air conditioning and eating areas for their comfort. Instead of attacking directly, the Germans invaded through the Low Countries, bypassing the Line to the north. French and British officers had anticipated this: when Germany invaded the Netherlands and Belgium, they carried out plans to form an aggressive front that cut across Belgium and connected to the Maginot Line. However, the French line was weak near the Ardennes forest. The French believed this region, with its rough terrain, would be an unlikely invasion route of German forces; if it was traversed, it would be done at a slow rate that would allow the French time to bring up reserves and counterattack. The German Army, having reformulated their plans from a repeat of the First World War - era plan, became aware of and exploited this weak point in the French defensive front. A rapid advance through the forest and across the River Meuse encircled much of the Allied forces, resulting in a sizeable force being evacuated at Dunkirk leaving the forces to the south unable to mount an effective resistance to the German invasion of France.
Document 9: First Battle of the Marne: The Battle of the Marne (French: Première bataille de la Marne, also known as the Miracle of the Marne, Le Miracle de la Marne) was a World War I battle fought from 6 -- 10 September 1914. It resulted in an Allied victory against the German armies in the west. The battle was the culmination of the German advance into France and pursuit of the Allied armies which followed the Battle of the Frontiers in August and had reached the eastern outskirts of Paris. A counter-attack by six French armies and the British Expeditionary Force (BEF) along the Marne River forced the Imperial German Army to retreat north - west, leading to the First Battle of the Aisne and the Race to the Sea. The battle was a victory for the Allied Powers but led to four years of trench warfare stalemate on the Western Front.

Document 11: Western Front (World War I): The Western Front was the main theatre of war during the First World War. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. The tide of the advance was dramatically turned with the Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918.
Document 12: Franco-Prussian War: While the republican government was amenable to war reparations or ceding colonial territories in Africa or in South East Asia to Prussia, Favre on behalf of the Government of National Defense, declared on 6 September that France would not "yield an inch of its territory nor a stone of its fortresses." The republic then renewed the declaration of war, called for recruits in all parts of the country and pledged to drive the German troops out of France by a guerre à outrance. Under these circumstances, the Germans had to continue the war, yet could not pin down any proper military opposition in their vicinity. As the bulk of the remaining French armies were digging-in near Paris, the German leaders decided to put pressure upon the enemy by attacking Paris. By September 15, German troops reached the outskirts of the fortified city. On September 19, the Germans surrounded it and erected a blockade, as already established at Metz.
Document 13: Miller Field (Staten Island): It was named after Captain James Ely Miller (1883–1918), commanding officer of the 95th Aero Squadron in the Air Service of the AEF, who died in combat on March 9, 1918 over Rheims in World War I. He was the first United States aviator killed in action while serving with an American military aviation unit. Before World War I Miller had been vice president of the Columbia Trust Company of New York and manager of its Fifth Avenue office who trained at his own expense to earn his pilot's license and Reserve Military Aviator rating with the Governors Island Training Corps in 1916. He was also an organizer, along with Major Raynal Bolling, of the 1st Reserve Aero Squadron, the first unit of what would eventually become the Air Force Reserve Command.
Document 14: John Herbert Hedley: Captain John Herbert Hedley (19 July 1887 – 1 April 1977) was a World War I British flying ace credited with eleven aerial victories. The observer ace claimed to have survived a bizarre flying mishap which earned him the moniker "The Luckiest Man Alive." Hedley also survived uninjured after his plane was shot down in 1918, and he became a prisoner of war. After his immigration to the United States in 1920, he became a regular on the lecture circuit, enthralling American audiences with the stories of his military service.
