Ex Input:
With the defeat of Marshal Bazaine's Army of the Rhine at Gravelotte, the French were forced to retire to Metz, where they were besieged by over 150,000 Prussian troops of the First and Second Armies. Napoleon III and MacMahon formed the new French Army of Chalons, to march on to Metz to rescue Bazaine. Napoleon III personally led the army with Marshal MacMahon in attendance. The Army of Chalons marched northeast towards the Belgian border to avoid the Prussians before striking south to link up with Bazaine. The Prussians, under the command of Field Marshal Count Helmuth von Moltke, took advantage of this maneuver to catch the French in a pincer grip. He left the Prussian First and Second Armies besieging Metz, except three corps detached to form the Army of the Meuse under the Crown Prince of Saxony. With this army and the Prussian Third Army, Moltke marched northward and caught up with the French at Beaumont on 30 August. After a sharp fight in which they lost 5,000 men and 40 cannons, the French withdrew toward Sedan. Having reformed in the town, the Army of Chalons was immediately isolated by the converging Prussian armies. Napoleon III ordered the army to break out of the encirclement immediately. With MacMahon wounded on the previous day, General Auguste Ducrot took command of the French troops in the field.

Ex Output:

The geographical regions in which Iranian languages were spoken were pushed back in several areas by newly neighbouring languages. Arabic spread into some parts of Western Iran (Khuzestan), and Turkic languages spread through much of Central Asia, displacing various Iranian languages such as Sogdian and Bactrian in parts of what is today Turkmenistan, Uzbekistan and Tajikistan. In Eastern Europe, mostly comprising the territory of modern-day Ukraine, southern European Russia, and parts of the Balkans, the core region of the native Scythians, Sarmatians, and Alans had been decisively been taken over as a result of absorption and assimilation (e.g. Slavicisation) by the various Proto-Slavic population of the region, by the 6th century AD. This resulted in the displacement and extinction of the once predominant Scythian languages of the region. Sogdian's close relative Yaghnobi barely survives in a small area of the Zarafshan valley east of Samarkand, and Saka as Ossetic in the Caucasus, which is the sole remnant of the once predominant Scythian languages in Eastern Europe proper and large parts of the North Caucasus. Various small Iranian languages in the Pamirs survive that are derived from Eastern Iranian.

The men's basketball team has over 1,600 wins, one of only 12 schools who have reached that mark, and have appeared in 28 NCAA tournaments. Former player Austin Carr holds the record for most points scored in a single game of the tournament with 61. Although the team has never won the NCAA Tournament, they were named by the Helms Athletic Foundation as national champions twice. The team has orchestrated a number of upsets of number one ranked teams, the most notable of which was ending UCLA's record 88-game winning streak in 1974. The team has beaten an additional eight number-one teams, and those nine wins rank second, to UCLA's 10, all-time in wins against the top team. The team plays in newly renovated Purcell Pavilion (within the Edmund P. Joyce Center), which reopened for the beginning of the 20092010 season. The team is coached by Mike Brey, who, as of the 201415 season, his fifteenth at Notre Dame, has achieved a 332-165 record. In 2009 they were invited to the NIT, where they advanced to the semifinals but were beaten by Penn State who went on and beat Baylor in the championship. The 201011 team concluded its regular season ranked number seven in the country, with a record of 255, Brey's fifth straight 20-win season, and a second-place finish in the Big East. During the 2014-15 season, the team went 32-6 and won the ACC conference tournament, later advancing to the Elite 8, where the Fighting Irish lost on a missed buzzer-beater against then undefeated Kentucky. Led by NBA draft picks Jerian Grant and Pat Connaughton, the Fighting Irish beat the eventual national champion Duke Blue Devils twice during the season. The 32 wins were the most by the Fighting Irish team since 1908-09.
