Input: Question: When did the leader of the troops that took 700 prisoners die? Passage:Close to the West Pennine Moors, Bolton is northwest of Manchester. It is surrounded by several smaller towns and villages that together form the Metropolitan Borough of Bolton, of which Bolton is the administrative centre. The town of Bolton has a population of 139,403, whilst the wider metropolitan borough has a population of 262,400. Historically part of Lancashire, Bolton originated as a small settlement in the moorland known as Bolton le Moors. In the English Civil War, the town was a Parliamentarian outpost in a staunchly Royalist region, and as a result was stormed by 3,000 Royalist troops led by Prince Rupert of the Rhine in 1644. In what became known as the Bolton Massacre, 1,600 residents were killed and 700 were taken prisoner.
