Question: Question: How long is the river that Jordanne flows into? Passage:Aurillac is at above sea level and located at the foot of the Cantal mountains in a small Sedimentary basin. The city is built on the banks of the Jordanne, a tributary of the Cère. It is south of Paris and north of Toulouse. Aurillac was part of a former Auvergne province called Haute-Auvergne and is only away from the heart of the Auvergne Volcano Park. Access to the commune is by numerous roads including the D922 from Naucelles in the north, the D17 from Saint-Simon in the north-east, Route nationale N122 from Polminhac in the east which continues to Sansac-de-Marmiesse in the south-west, the D920 to Arpajon-sur-Cère in the south-east, and the D18 to Ytrac in the west. The Figeac-Arvant railway passes through the commune with a station in the centre of town but there is no TGV service. About 50% of the commune is urbanised with farmland to the east and west of the urban area.

Question: Question: Who won the battle where Hugh Mercer was killed? Passage:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey.

Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.
