Salient (military)A salient, also known as a bulge, is a battlefield feature that projects into enemy territory. The salient is surrounded by the enemy on multiple sides, making the troops occupying the salient vulnerable. The opponent's front line that borders a salient is referred to as a re-entrant – that is, an angle pointing inwards. A deep salient is vulnerable to being "pinched off" through the base, and this will result in a pocket in which the forces in the salient become isolated and without a supply line.
German spring offensiveThe German spring offensive, or Kaiserschlacht ("Kaiser's Battle"), also known as the Ludendorff offensive, was a series of German attacks along the Western Front during the First World War, beginning on 21 March 1918. Following American entry into the war in April 1917, the Germans decided that their only remaining chance of victory was to defeat the Allies before the United States could ship soldiers across the Atlantic and fully deploy its resources.
Battle of PasschendaeleThe Third Battle of Ypres (Dritte Flandernschlacht; Troisième Bataille des Flandres; Derde Slag om Ieper), also known as the Battle of Passchendaele (ˈpæʃəndeɪl), was a campaign of the First World War, fought by the Allies against the German Empire. The battle took place on the Western Front, from July to November 1917, for control of the ridges south and east of the Belgian city of Ypres in West Flanders, as part of a strategy decided by the Allies at conferences in November 1916 and May 1917.
Battle of Mont SorrelThe Battle of Mont Sorrel (Battle of Mount Sorrel, Battle of Hill 62) was a local operation in World War I by three divisions of the German 4th Army and three divisions of the British Second Army in the Ypres Salient, near Ypres in Belgium, from 2 to 13 June 1916. To divert British resources from the build-up being observed on the Somme, the XIII (Royal Württemberg) Corps and the 117th Infantry Division attacked an arc of high ground defended by the Canadian Corps in Flanders.
Trench warfareTrench warfare is the type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. It became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914. Trench warfare proliferated when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage.
Hundred Years' WarThe Hundred Years' War (La guerre de Cent Ans; Dgère d'Un Chint An; 1337–1453) was a series of armed conflicts fought between the kingdoms of England and France during the Late Middle Ages. It originated from English claims to the French throne. The war grew into a broader power struggle involving factions from across Western Europe, fueled by emerging nationalism on both sides. The Hundred Years' War was a significant conflict in the Middle Ages.
Battle of FranceThe Battle of France (bataille de France; 10 May – 25 June 1940), also known as the Western Campaign (German: Westfeldzug), the French Campaign (Frankreichfeldzug, campagne de France) and the Fall of France, was the German invasion of France during the Second World War. France and the Low Countries were conquered, ending land operations on the Western Front until the Normandy landings on 6 June 1944. On 3 September 1939, France declared war on Germany following the German invasion of Poland.
Race to the SeaThe Race to the Sea (Course à la mer; Wettlauf zum Meer, Race naar de Zee) took place from about 1914 during the First World War, after the Battle of the Frontiers () and the German advance into France. The invasion had been stopped at the First Battle of the Marne (5–12 September) and was followed by the First Battle of the Aisne (13–28 September), a Franco-British counter-offensive. The term describes reciprocal attempts by the Franco-British and German armies to envelop the northern flank of the opposing army through the provinces of Picardy, Artois and Flanders, rather than an attempt to advance northwards to the sea.
