Input: Question: What is the population of the city USS Corry went to in October of 1942? Passage 1:The general outline of the Roman conquest of Britain during the 1st century AD is recorded by historical sources; for the involvement of specific forts historians depend on archaeological excavations. This part of Britain was occupied by a tribe known as the Cornovii. In AD 46–47 the Roman Army led by governor Aulus Plautius had probably occupied the lands to the south of the River Trent. Late in 47 the new governor of Britain, Ostorius Scapula, began a campaign against the tribes of the western mountains (modern Wales). Caratacus, their leader, was defeated in battle in AD 50 and fled to the Brigantes who occupied the Pennines. Their queen, Cartimandua, came to terms with the Romans and handed Caratacus over to them. Ostorius died and was replaced by Aulus Gallus who brought the Welsh borders under control but did not move further north or west. It was at about this time that the fort at Strutt's Park was built. It probably lay not far south of the border between Roman territory and that held by the Brigantes, who were now an allied or subject kingdom.
 Passage 2:Corry cleared Bermuda on 25 October 1942 for Casablanca to participate in the Moroccan landings, in the screen of the aircraft carrier . She left Casablanca 16 November for Norfolk and Boston, and after overhaul resumed her coastal and Caribbean operations until 13 February 1943, when she sailed on escort duty from Norfolk for north Africa, returning 6 March for operations in the western Atlantic. On 11 August she sailed for Scotland and operated with the British Home Fleet, cruising once to Norway as providing escort for Ranger in the successful Allied air raid on Bodø, Norway in October 1943 (Operation Leader). Corry sailed twice to Iceland to cover the movement of Russia-bound convoys. Returning to Boston on 3 December, Corry sailed on 24 December for escort duty to New Orleans and Panama.
 Passage 3:In 1854 Klindworth went to London, where he remained for fourteen years, studying, teaching and occasionally appearing in public. From London Klindworth went to Moscow in 1868, following Nikolai Rubinstein's invitation to take up the position of professor of pianoforte at the Moscow Conservatory, where he first met Pyotr Ilyich Tchaikovsky as professor of harmony. While in Russia he completed his pianoforte arrangements for Wagner's Der Ring des Nibelungen, which he had commenced during Wagner's visit to England in 1855, Beethoven's sonatas and also his critical edition of Frédéric Chopin's works. He then became conductor of the Berlin Philharmonic in 1882, in association with Joseph Joachim and Franz Wüllner, being also the conductor of the Berlin Wagner Society. At this time, he established the Klindworths Musikschule, which later became the Klindworth-Scharwenka Conservatory.
