Question: How long had Prussia been a country for the year the French withdrew from the Rhine? Passage 1:In the course of the French occupation of the lands on the Rhine’s left bank in the wake of the Treaty of Lunéville, Rhaunen was grouped into the Department of Sarre, the arrondissement of Birkenfeld and the canton of Rhaunen. After the French withdrew in 1814, Rhaunen found itself in Prussia’s new Rhine Province, also becoming the seat of a Bürgermeisterei (“mayoralty”) in the Bernkastel-Kues district. Parts of the old high court district, however – Bundenbach, for instance – now belonged to the Principality of Birkenfeld, an exclave of the Grand Duchy of Oldenburg, most of whose territory was in what is now northwest Germany, with a coastline on the North Sea. Even after the First World War, through the Weimar Republic and on through the time of the Third Reich, Rhaunen was the administrative seat for the surrounding villages. In the course of administrative restructuring in the 1960s, the Amt of Rhaunen became the Verbandsgemeinde of Rhaunen in the Birkenfeld district. This arrangement still stands.
 Passage 2:Laskov joined the Haganah as a teenager, and served in various units, including Orde Wingate's Special Night Squads. He also served as a personal messenger for Yaakov Dori, who would later become the first Chief of Staff. In 1940, Laskov joined the British Army so that he could participate in World War II. He served in various capacities, and was a commander of the Jewish Brigade which saw action on the Italian front, eventually reaching the rank of major. After the war, he remained in Europe to participate in the Aliyah Bet illegal immigration effort to bring refugee Jews to Palestine. He also took part in various illicit acts of vengeance against the Nazis and their collaborators. Upon eventually returning to Palestine, he rejoined the Haganah, while also working as chief of security for the electric company.
 Passage 3:He was arrested on 3 August 1944 at the Gare Montparnasse, and questioned harshly by the Gestapo at the Rue des Saussaies. He lost consciousness under the beatings but did not divulge any names; he was subsequently held at Fresnes Prison. Debeaumarché was one of the so-called "77,000" (named for the prisoners' numbers, between 76,000 and 78,000), Fresnes prisoners who were transported by train from Pantin to Buchenwald on 15 August 1944. He was moved to the underground factory of Mittelbau-Dora which produced V-1 flying bombs and V-2 rockets, and posing as an electrical engineer was put to work in the manufacture of the V-1. Maurice Naegelé, a Kapo in the tunnel assembly section, gained the trust of Debeaumarché by relating details of the resistance movement in France. In fact Naegelé had been an agent of the Gestapo, before his deportation. Naegelé denounced Debeaumarché to SS-Oberscharführer Sander, head of surveillance at Mittelbau-Dora. Debeaumarché was arrested with others (including Naegelé) on the night of 3–4 November 1944. They were taken to the Niedersachswerfen SD headquarters, where Naegelé attempted to beat confessions out of the other prisoners. Debeaumarché was sentenced to death on 11 November 1944, but the sentence was not carried out. Instead Debeaumarché was held in solitary confinement, accused of anti-Nazi plotting. In April 1945 he was moved to Bergen-Belsen, where he was liberated during the advance of Allied troops on 15 April 1945 and repatriated to France. On 1 May 1945 he marched down the Champs-Élysées alongside fellow Buchenwald-captive Pierre Dejussieu-Pontcarral.
