Question: When Copsi was made earl of Northumbria he went back to reside in a town at the confluence of which two rivers?

Copsi (or Copsig; Old English: "Cōpsige" ) [died 1067] was a Northumbrian magnate in late Anglo-Saxon England.  He was a supporter of Tostig, and was exiled along with him in 1065.  Copsi soon fled to Orkney (then a part of Norway).  The next year (1066), he joined Tostig at Sandwich, in Kent, with 17 ships.  Copsi survived Tostig's defeat at Stamford Bridge, and when William the Conqueror prevailed at Hastings he travelled, in March 1067, to pay William homage at Barking (where William was staying while his tower was being constructed in London).  Copsi's rule lasted a mere five weeks, at which time he was murdered by Osulf, son of Eadulf III of the ancient Bernician family which had historically governed the area from Bamburgh, at Newburn-upon-Tyne.  Osulf, however, only ruled as earl until that autumn, when he was killed by an outlaw he was tracking.  In return, William made Copsi earl of Northumbria and sent him back to York. <SEP>  The municipality is the traditional county town of the historic county of Yorkshire to which it gives its name.  The city has a rich heritage and has provided the backdrop to major political events in England throughout much of its two millennia of existence. York ( ) is a historic walled city at the confluence of the rivers Ouse and Foss in North Yorkshire, England.  The city offers a wealth of historic attractions, of which York Minster is the most prominent, and a variety of cultural and sporting activities making it a popular tourist destination for millions. <SEP> Duke of Bedford (named after Bedford, England) is a title that has been created six times (for five distinct people) in the Peerage of England.  The first and second creations came in 1414 in favour of Henry IV's third son, John, who later served as regent of France.  He was made Earl of Kendal at the same time and was made Earl of Richmond later the same year.  The titles became extinct on his death in 1435.  The third creation came in 1470 in favour of George Neville, nephew of Warwick the Kingmaker.  He was deprived of the title by Act of Parliament in 1478.  The fourth creation came 1478 in favour of George, the third son of Edward IV.  He died the following year at the age of two.  The fifth creation came in 1485 in favour of Jasper Tudor, half-brother of Henry VI and uncle of Henry VII.  He had already been created Earl of Pembroke in 1452.  However, as he was a Lancastrian, his title was forfeited between 1461 and 1485 during the predominance of the House of York.  He regained the earldom in 1485 when his nephew Henry VII came to the throne and was elevated to the dukedom the same year.  He had no legitimate children and the titles became extinct on his death in 1495. <SEP> Karad is a city in Satara district in the southern part of Indian state of Maharashtra.  It lies at the confluence of Koyna River and the Krishna River.  The two rivers originate at Mahabaleshwar, which is around 100 km from Karad.  They diverge at their origin, and travel for about the same distance to meet again in Karad.  The rivers meet exactly head on, thus forming letter "T" which is the only head on confluence in the world.  Hence Krishna and koyna river's confluence is called Preeti Sangam, meaning Confluence of Love.  Karad is well known for sugar production and is known as the sugar bowl of Maharashtra owing to the presence of many sugar factories in and around Karad.  It is considered as an important educational hub in Western Maharashtra due to the presence of many prestigious educational institutes.
