Question: How many people lived in Nancy the year the Second Armistice at Compiègne was signed? Passage 1:Originally from the small city of Minden in Webster Parish in northwestern Louisiana, Spiva was the son of Hubert Spiva, Sr. (1899-1939), a former foreign correspondent, and the former Lilla Ellenor Stewart (1906–1959), who married in 1929. They operated the Webster Printing Company and the former The Minden Herald and The Webster Review newspapers, forerunners of the Minden Press-Herald. Lilla Spiva, a scion of a prominent Webster Parish family, was a daughter of Minden attorney Daniel Webster Stewart, Sr. (1857-1935), and his wife, the former Alice Leona Reagan (1871-1954). She was a niece of William Green Stewart, a farmer and a former president of the Webster Parish School Board, for whom the since defunct William G. Stewart Elementary School in Minden is named. Another uncle, E. L. Stewart, was a member of the Louisiana House of Representatives at the time of her birth. Known as "Babe", Lilla Spiva managed the papers after her husband's death at the age of forty and was herself publisher and society editor of the Minden Herald and a member of the Louisiana Press Association. On January 23, 1960, the press association posthumously honored her for her journalistic accomplishments. Hubert Spiva is interred at Mount Hope Cemetery in Webb City in Jasper County in southwestern Missouri. Lilla is interred with other Stewart relatives at the historic Minden Cemetery. Spiva's aunt, Lilla's sister, was Mary Amanda Stewart (1903–1994), whom he visited in the Stewart home, later the Farley home, when he returned to his hometown.
 Passage 2:Six units of the French Foreign Legion participated in the Battle of France: the 11th Foreign Infantry Regiment, the 12th Foreign Infantry Regiment, the Reconnaissance Group of the 97th Infantry Division, the 21st Marching Regiment of Foreign Volunteers (21st RMVE), the 22nd Marching Regiment of Foreign Volunteers, and the 23rd Marching Regiment of Foreign Volunteers. The 11th REI defended the northern Inor Wood near Verdun from the German offensive early on in the battle until June 11, 1940 when the regiment began a fighting retreat to the south. By June 18, the 11th REI had lost three-fourths of its strength and the regiment withdrew to the south near Toul. The 12th REI was redeployed from its training center in Valbonne on May 11 to defend the Soissons where it arrived on May 24 and eventually began to fortify their positions. The 12 REI first experienced a form of combat for which they were unprepared when on June 5, the town of Soissons was the subject of German strafing from Stukas. By June 8, the 12th REI, in danger of being encircled, received orders to retreat to the south, however the orders did not come soon enough and parts of the 12th REI were surrounded at Soissons; the rest of the 12th REI made their way to Limoges by the signing of Second Armistice at Compiègne on June 25, 1940. By the surrender of France the 12th REI had lost 2,500 of its number. The 21st Marching Regiment of Foreign Volunteers was deployed to the Maginot Line when the German offensive began, but was shifted to the north of Verdun by the end of May. The 21st RMVE took heavy losses during an engagement with the Germans on June 8 and 9; the 21st RMVE joined the rest of the French Army in that sector in retreat when the order to retreat was given. At the time of the armistice the 21st RMVE was at Nancy where it was disarmed by German forces. The 22nd Marching Regiment of the Foreign Volunteers left its training depot at Bacarès on May 6 when it was deployed around Alsace. The German offensive forced the 22nd RMVE to be quickly redeployed on the Somme near the village of Marchélepot where it fought a defensive action from May 22 to May 26. On June 5, the 22nd RMVE was preparing to counterattack the Germans at Villers-Carbonnel alongside the 112th Infantry Division when it came under a heavy preemptive attack launched by German forces in the area. The French Forces were able to initially repulse the attack, but later succumbed to the German onslaught; the force of the Foreign Legion acquitted themselves admirably in that engagement.
 Passage 3:On 6 September that year, Pope Urban VI declared that as James of Baux's successors had forfeited their rights to the Holy See, the principality belonged to him and he devolved its government on Paul Foscari, the archbishop of Patras, who in turn made Pedro vicar general. Pedro was constantly at war with the Despotate of Morea, against whom he even used Ottoman pirates, and the Duchy of Athens under Nerio I Acciaioli. The latter was captured near Vostitsa on 10 September 1389 while trying to sit to talks with Pedro concerning Argos and Nauplia. He had to buy his freedom with concessions to the Navarrese ally, Venice. Late in 1394 or early in 1395, the Turkish general Evrenos Beg invaded the despotate and met Pedro's forces at Leontari. Together the two besieged and took Akova (28 February). After Evrenos returned to Thessaly, Pedro was defeated by the Greeks and taken captive with the grand constable Andronico Asano Zaccaria, his brother-in-law. In December, Venice paid 50,000 hyperpers for the release of her allies.
