Question: Question: How long did the war that the North Irish Horse unit was raised in the aftermath of last? Passage:The North Irish Horse is a yeomanry unit of the British Territorial Army raised in the northern counties of Ireland in the aftermath of the Second Boer War. Raised and patronized by the nobility from its inception to the present day, it was one of the first non-regular units to be deployed to France and the Low Counties with the British Expeditionary Force in 1914 during World War I and fought with distinction both as mounted troops and later as a Cyclist Regiment, achieving 18 battle honours. The regiment was reduced to a single man in the inter war years and re-raised for World War II, when it achieved its greatest distinctions in the North African and Italian campaigns. Reduced again after the Cold War, the regiment's name still exists in B (North Irish Horse) Squadron, the Scottish and North Irish Yeomanry and 40 (North Irish Horse) Signal Squadron, part of 32 Signal Regiment.

Question: Question: What year was the monument that commemorated French victory at the Battle of Grand Port completed? Passage:During the Napoleonic wars, Ile de France became a base from which the French navy, including squadrons under Rear Admiral Linois or Commodore Jacques Hamelin, and corsairs such as Robert Surcouf, organised raids on British merchant ships. The raids (see Battle of Pulo Aura and Mauritius campaign of 18091811) continued until 1810 when the British sent a strong expedition to capture the island. The first British attempt, in August 1810, to attack Grand Port resulted in a French victory, one celebrated on the Arc de Triomphe in Paris. A subsequent and much larger attack launched in December of the same year from Rodrigues, which had been captured a year earlier, was successful. The British landed in large numbers in the north of the island and rapidly overpowered the French, who capitulated (see Invasion of Isle de France). In the Treaty of Paris (1814), the French ceded Ile de France together with its territories including Rodrigues and Seychelles to Great Britain. The island then reverted to its former name, 'Mauritius'.

Question: Question: How long did the Metropolitan of All Rus' hold that title? Passage:Stephen was probably from the town of Ustiug. According to a church tradition, his mother was a Komi woman and his father was a Russian man. Stephen took his monastic vows in Rostov, where he learned Greek and learned his trade as a copyist. In 1376, he voyaged to lands along the Vychegda and Vym rivers, and it was then that he engaged in the conversion of the Zyriane (Komi peoples). Rather than imposing the Latin or Church Slavonic on the indigenous pagan populace, as all the contemporary missionaries did, Stephen learnt their language and traditions and worked out a distinct writing system for their use, creating the second oldest writing system for a Uralic language. Although his destruction of pagan idols (e.g., holy birches) earned him the wrath of some Permians, Pimen, the Metropolitan of All Rus', created him as the first bishop of Perm'.
