SaarbrückenSaarbrücken (zaːɐ̯ˈbʁʏkn̩; Sarrebruck saʁbʁyk; Rhine Franconian: Saarbrigge zaːˈbʁɪɡə; Saarbrécken zaːˈbʀekən; Saravipons) is the capital and largest city of the state of Saarland, Germany. Saarbrücken is Saarland's administrative, commercial and cultural centre and is next to the French border. The modern city of Saarbrücken was created in 1909 by the merger of three towns, Saarbrücken, St. Johann, and Malstatt-Burbach. It was the industrial and transport centre of the Saar coal basin.
BlockhouseA blockhouse is a small fortification, usually consisting of one or more rooms with loopholes, allowing its defenders to fire in various directions. It is usually an isolated fort in the form of a single building, serving as a defensive strong point against any enemy that does not possess siege equipment or, in modern times, artillery, air force and cruise missiles. A fortification intended to resist these weapons is more likely to qualify as a fortress or a redoubt, or in modern times, be an underground bunker.
Trench railwaysTrench railways represented military adaptation of early 20th-century railway technology to the problem of keeping soldiers supplied during the static trench warfare phase of World War I. The large concentrations of soldiers and artillery at the front lines required delivery of enormous quantities of food, ammunition and fortification construction materials where transport facilities had been destroyed. Reconstruction of conventional roads (at that time rarely surfaced) and railways was too slow, and fixed facilities were attractive targets for enemy artillery.
