Question: Passage: From 1805 onwards, Ruty took part to the campaigns of the Grande Armée during the War of the Third Coalition and War of the Fourth Coalition, serving as artillery park director for the Army Corps of Marshal Michel Ney, then Marshal Joachim Murat. A brigadier general from 1807, he served with distinction at the battle of Friedland. In 1808 he was created a baron of the Empire, serving as commander of the artillery school in Toulouse, before being sent to serve in Spain, towards the end of that year. He contributed significantly to the successful sieges of Ciudad Rodrigo and Almeida, before taking command of Marshal Jean-de-Dieu Soult's artillery in the armies of the South and of Andalusia. During this campaign he invented a type of howitzer that bears his name. In 1813, Ruty was recalled to France, and promoted to general of division, before being named commander of Marshal Nicolas Oudinot's Corps artillery during the Saxon campaign of the War of the Sixth Coalition. In November 1813, Ruty was created a count of the Empire. After Napoleon's abdication in 1814, Ruty served the Bourbon Restoration, but during the Hundred Days he joined the Emperor, who named him commander of the artillery of the Army of the North, with Ruty playing a significant role at the battle of Waterloo. General count de Ruty finished his military career as general inspector for artillery during the Second Restoration, subsequently serving as general director for gunpowders and saltpeter (1817), state counsellor (1818) and Peer of France from 1819.

Question: Passage: In 1809, Walter Coffin sunk the first coal pit in the Rhondda, further up the valley in Dinas, but a lack of a transportation network greatly affected the profitability of coal mining as an industry in the region. Coffin tackled this problem by constructing a one-mile tramline which connected his mines in Dinas to a tramline built by Dr. Richard Griffiths at Denia (Pontypridd), which linked to a private canal that joined onto the Glamorganshire Canal at Treforest. Coffins tramline followed the southern bank of the River Rhondda and ran through Porth. The existence of the tramline made the development of the Porth and Cymmer region far more attractive, and by the middle of the 19th century there was an impetus to expand coal mining in the area. In 1841 Richard Lewis joined Coffin in trying to exploit the region with his level built at Cymmer. This resulted in the construction of around fifty miners' cottages, several of which were located in Porth. In 1844 Lewis Edwards of Newport and George Gethin of Penygraig opened a small level at Nyth-bran on the eastern borders of Porth, the villages' first coal mine. This was followed in 1845 by the sinking of the Porth Colliery by David James of Merthyr, the success of which saw him build the Llwyncelyn Colliery in 1951, also in Porth. By 1850 the Taff Vale Railway had been extended to Cymmer replacing the tramline, allowing direct access between the lower Rhondda and the ports of Cardiff.
 Link Information: It was opened in stages in 1840 and 1841. Answer: 10

Answer: How long had the Taff Vale Railway been in existence the year it was extended to Cymmer?


Question: Passage: His plea was approved by the Shella Presbytery on 15 February. He left Shella on 18 February (Wednesday) and spent the following Sunday at Sylhet. He met Benjamin Aitken, an elder of Free Church of Scotland and sub-editor of Calcutta-based newspaper The Englishman, who volunteered to join him in his expedition. His frequent companion Kasinath, a young Assamese Christian who was preaching that afternoon, and one Khasi Christian U Khanai also joined him. On Monday 23 February the four set sail on a boat on Surma River, preaching to people along their journey. They spent Sunday 1 March at Silchar and moved the next day. On the third day they arrived at Jhalnacherra and spent a night at Alexandrapur tea garden where Mary Winchester was kidnapped by Mizo Warriors in 1871, the origin of British encounter with Mizos. On Thursday they continued their journey and after a week on Tlawng River, they reach Guturmukh (Kutbûl Kai in Mizo), a British telegraph station at the Tut River junction, on 11 March. Here they stayed for four days and saw the first thatched huts of Mizos at a distant hill top, including stockades used during the British military expedition. On Sunday 15 March afternoon they met roaming native Mizos for the first time in their boat ride. They were friendly boys between 10 and 15 years old from neighbouring village, Liankunga chiefdom. They exchanged salt and tobacco for the boys' yams and bananas. They gave them some boxes of matches, and Bible pictures. They also sang several songs to them which they "listened with their mouths open." On Monday afternoon they arrived at Changsil, where they camped among the military escort commanded by Captain Williamson. With the army they moved on Thursday to Sairang where they spent the night. Army horses arrived in the next morning and they headed for Aizawl ("Fort Aijal" as it was called). They reached Aizawl at noon on 20 March. They stayed there for four weeks, learning about Mizo lifestyle, distributing Bible pictures and preaching among non-Mizo such as Khasi, Manipuri, and Naga workers stationed there. Full of hope to return and start formal education and evangelism, they left Aizawl on 17 April. He published his appeal to open mission field in Lushai Hills in June and July 1891 issue of Y Goleuad. Welsh General Assembly at Machynlleth in June 1892 decided to adopt Lushai Hills as an extension of the Khasi Hills mission field. By then Williams had died of typhoid on 21 April 1892 at Mawphlang, some 25 km from Shillong city.
