Most were still unfinished in 1870 when the Franco-Prussian War burst out. During it was held by Germany, the German garrison at Metz oscillated between 15,000 and 20,000 men at the beginning of the period.{{Cite book|author = René Bour|title = Histoire de Metz|year = 1950|page = 227}} and exceeded 25,000 men just before the First World War,{{Citation|periodical = L'Express|number = 2937|date = 18 October 2007|title = Metz en 1900|author = Philippe Martin}}. It gradually became the premier stronghold of the German Reich.François Roth, Metz annexée à l’Empire allemand, in François-Yves Le Moigne, Histoire de Metz Toulouse, Privat, 1986 p.350

The Feste Schwerin is designed in the spirit of the "detached forts" concept developed by Hans Alexis von Biehler in Germany. The goal was to form a discontinuous enclosure around Metz with strong artillery batteries spaced with a range of guns. The fort was built by German engineers between 1878 and 1880.

From 1890 the garrison manned by the Corps XVI, stationed at Metz and Thionville. When it was taken over by the French army in 1919, the fort was renamed Fort Decaen. It was taken in 1940 by the Germans, who occupied it 1940–1944. Fort Decaen is no longer in use.

In early September 1944, at beginning of the Battle of Metz, and the German command integrated the defensive system set up around Metz. On September 2, 1944, Metz was declared one of the "Hitler fortresses", that must be defended to the last by German troops.{{Cite book|author=René Caboz|title = La bataille de Metz|editor = Éditions Pierron|location = Sarreguemines|year = 1984|page = 132}} The next day, September 3, 1944, the troops of General Walther Krause took position on a line from Pagny-sur-Moselle to Mondelange, passing west of Metz by Chambley-Bussières, Mars-la-Tour, Jarny and Briey. After an initial withdrawal on 6 September 1944, German lines rested firmly on the Forts of Metz. On November 9, 1944, as a prelude to the Allied assault on Metz, as many as 1,299 heavy bombers, B-17s and B-24s, dumped hundreds of bombs on fortifications and strategic points in the combat zone of the United States IIIrd army.{{Cite book|author = Général Jean Colin|title = Contribution à l'histoire de la libération de la ville de Metz: Les combats du fort Driant (septembre-décembre 1944)|editor = Académie nationale de Metz|year = 1963|page = 13}} Most bombers dropped their bombs without visibility from over 20,000 feet, so the military targets were often missed. At Metz the 689 loads of bombs destined to strike the seven forts, designated as priority targets, did nothing but collateral damage.{{Harvard citation|Cole|1950|id = cole1950|p = 424}}.

The Fort Jeanne d'Arc was the last of the forts of Metz to surrender. Determined German resistance, bad weather and floods, inopportunity, and a general tendency to underestimate the firepower of the fortifications of Metz, helped slow the US offensive, giving the opportunity to the German Army to withdraw in good order to the Saarland.{{Harvard citation|Cole|1950|id = cole1950|p = 448}} The objective of the German staff, which was to stall US troops for the longest possible time at Metz before they could reach the Siegfried Line, was largely achieved.
