Question: What factions were involved in the war? Passage 1:Taylor was a pupil at Moorside High School in Swinton, Greater Manchester and was associated with Manchester United as a schoolboy until he was not offered a scholarship at Old Trafford at the age of 16. In July 2015 he began a two-year apprenticeship at Nottingham Forest's youth-team. On 30 August 2019, he joined EFL League Two side Port Vale on loan after impressing manager John Askey in training games during a trial spell. Taylro said that "Port Vale have strong links with Forest, as you have seen with Adam Crookes and also Toby Edser came in. Phil Sproson is good friends with the academy manager Gary Brazil so the link is there. They have shown an interest and I have jumped at it." He made his debut the following day, coming on as a 67th-minute substitute for Cristian Montaño in a 1–0 win over Cambridge United at Vale Park. He later said that "I knew it would be physical but I think I have dealt with that quite well. Probably the speed of the game has surprised me." On 24 September, he scored his first goal in senior football in a 3–2 victory at Macclesfield Town in the EFL Trophy. He scored his first league goal four days later, bending the ball into the top corner from the edge of the penalty area in a 3–3 draw at Leyton Orient. On 2 November, he scored the only goal of the game at local rivals Crewe Alexandra.
 Passage 2:In 1873, the Hoylake and Birkenhead Railway was authorised to construct two extensions to its lines. One was a short connecting section near to Birkenhead docks, and the other was the extension from Hoylake to West Kirby. The station and the extension were opened on 1 April 1878 as the terminus of the Wirral Railway's route from Birkenhead Park station. The station's original signal box was built in 1886, to a London and North Western Railway (LNWR) design. This signal box was removed and replaced in 1932. After the opening of the Mersey Railway Tunnel in 1886, carriages were operated through Birkenhead Park, every half-hour, all the way to James Street station in Liverpool. As traffic increased, the line into West Kirby was doubled, from a single track, in 1896. After a board meeting on 28 October 1895, it was decided to extend the line from Hooton, into West Kirby. The station was relocated on the western side of the original station, with an enlarged island platform and rebuilt, in 1898-9, in red brick, with a turreted clock tower and mock Tudor frontage. A further platform was constructed for the Hooton line, on the eastern side of the original station. The site of the original station was used for goods sidings. In the present day, this is the site of The Concourse, a community building operated by Wirral Metropolitan Borough Council.
 Passage 3:The regiment was raised by the Honourable East India Company as the Madras Europeans from independent companies in 1742 – "European" indicating it was composed of white soldiers, not Indian sepoys. It saw action at the Siege of Arcot in autumn 1751 during the Second Carnatic War and went on to fight at the Battle of Plassey in June 1757, the Battle of Condore in December 1758 and the Battle of Wandiwash in January 1760 during the Seven Years' War. It also fought at the Siege of Pondicherry in September 1760 during the Third Carnatic War. It became the 1st Madras Europeans, on formation of the 2nd and 3rd Madras Europeans, in 1766. It went on to become the 1st Madras European Regiment in 1774. After that it took part in the Siege of Nundydroog in October 1791 and the Siege of Seringapatam in February 1792 during the Third Anglo-Mysore War.
