Input: Consider Input: Question: How many years did the war last where the castle was strengthened in the middle of it? Passage:In 1575, in the middle of the Wars of Religion, the castle was strengthened. It was nevertheless besieged and taken by the Geuzen, locally known as the Hurlus in 1579, before being taken back three months later. In 1627, Philip IV of Spain promoted the seigneury to the rank of county. The Franco-Dutch War under Louis XIV devastated this mostly agricultural region. Mouscron and the surrounding area became French after the Treaty of Aix-la-Chapelle (1668). Part of it rejoined the Southern Netherlands after the Treaty of Nijmegen (1678), which drew the frontier right through its territory. It was finally completely ceded to the Southern Netherlands under the terms of the Treaty of Utrecht in 1713. The textile industry started in Mouscron in the 1760s thanks to the imposition by Lille of a ban on the fabrication of molletons, a mixture of flax and wool, in Roubaix and Tourcoing. With the Battle of Fleurus (1794), Mouscron went back to France.

Input: Consider Input: Question: What is the area of the land Greaves owned in Sussex? Passage:Charles I is supposed to have created him a baronet 4 May 1645. Of this creation, the first of a physician to that rank, no record exists, but the accurate Le Neve did not doubt the fact, and explained the absence of enrolment. He claimed to have been Physician-General to the army of Charles I. With his friend Walter Charleton, Greaves became travelling physician to Charles II, but settled in London in 1653, and was admitted a fellow of the College of Physicians 18 October 1657. He delivered the Harveian oration at the College of Physicians 25 July 1661 (London, 1667, 4to), of which the original manuscript is in the British Museum (Sloane 302). He says that before Harvey the source of the circulation was as unknown as that of the Nile, and compares England to a heart, whence the knowledge of the circulation was driven forth to other lands. He became physician in ordinary to Charles II, and owned the lands of St Leonard's Forest in Sussex, including that part which became Leonardslee. He married Alicia Nevett (16241684), widow of Peter Calf (d. 1668). Greaves lived in Covent Garden, died there 11 Nov. 1680, and was buried in the church of St. Paul's, Covent Garden.
