Problem:Question: How long had Mehmed been a Sultan when his forces conquered Constantinople? Passage 1:The British eventually recaptured Grappler from the French in September 1809 in the daring raid on Saint-Paul on the Île de Bourbon (now Réunion) from the nearby British-held island of Rodrigues. The British force consisted of a naval squadron under Commodore Josias Rowley and an Army force under Lieutenant Colonel Henry Sheehy Keating. The Army contingent, which consisted of 368 soldiers from the 1st Battalion of the 56th Regiment of Foot under the command Keating, embarked on HMS Nereide under Captain Robert Corbett, Otter under Captain Nesbit Willoughby and the East India Company schooner Wasp under Lieutenant Watkins. The rest of Rowley's squadron, the flagship , and the frigates under Captain Samuel Pym and HMS Boadicea under Captain John Hatley joined off St. Paul. These ships contributed an additional 236 seaman volunteers and Royal Marines to the assault. The entire invasion force then embarked on Nereide, as Corbett had experience with coastline of the Île Bonaparte coastline. On the early morning of 21 September the force seized the port of St. Paul. There they destroyed its defences and recovered a number of British vessels. Nereide and the landing party captured the 44-gun French frigate Caroline, and recovered Grappler as well as the East Indiamen (850 tons (bm) and pierced for 30 guns) and (820 tons (bm) and pierced for 26 guns). The expedition also captured three small merchant vessels (Fanny of 150 tons, and Tres Amis and Creole of 60 tons each), destroyed three others, and burnt one ship that was building on the stocks. The British did not sustain any loss on board the squadron or to their vessels. The British completed the demolition of the different gun and mortar batteries and of the magazines by evening and the whole of the troops, marines, and seamen returned on board their ships.
 Passage 2:This is a list of campaigns personally led by Mehmed II or Sultan Mehmed the Conqueror (30 March 1432 – 3 May 1481) (Ottoman Turkish: محمد ثانى, Meḥmed-i s̠ānī; Turkish: II. Mehmet; also known as el-Fātiḥ, الفاتح, "the Conqueror" in Ottoman Turkish; in modern Turkish, Fatih Sultan Mehmet; also called Mahomet II in early modern Europe) was Sultan of the Ottoman Empire twice, first for a short time from 1444 to September 1446, and later from February 1451 to 1481. At the age of 21, he conquered Constantinople and brought an end to the Byzantine Empire, transforming the Ottoman state into an empire. Mehmed continued his conquests in Asia, with the Anatolian reunification, and in Europe, as far as Bosnia and Croatia. Mehmed II is regarded as a national hero in Turkey, and Istanbul's Fatih Sultan Mehmet Bridge is named after him.
 Passage 3:From the beginning of the city's history as the western bank of Springfield, Irish families have resided in and contributed to the development of the civics and culture of Holyoke, Massachusetts. Among the first appellations given to the city were the handles "Ireland", "Ireland Parish", or "Ireland Depot", after the village was designated the 3rd Parish of West Springfield in 1786. Initially occupied by a mixture of Yankee English and Irish Protestant families, many of whom belonged to the Baptist community of Elmwood, from 1840 through 1870 the area saw a large influx of Irish Catholic workers, immigrants to the United States, initially from the exodus of the Great Famine. During that period Irish immigrants and their descendants comprised the largest demographic in Holyoke and built much of the early city's infrastructure, including the dams, canals, and factories. Facing early hardships from Anti-Irish sentiment, Holyoke's Irish would largely build the early labor movement of the city's textile and paper mills, and remained active in the national Irish nationalist and Gaelic revival movements of the United States, with the Holyoke Philo-Celtic Society being one of 13 signatory organizations creating the Gaelic League of America, an early 20th century American counterpart of Conradh na Gaeilge.
