Indeed, the events of 1857 led to a spurt in the European population of Mussoorie-Landour, with many families leaving the 'exposed' towns of the Gangetic Plain. Among the Britons who thus moved to Landour were the parents of Jim Corbett. Both had lost their spouses, and would meet and remarry in Landour (see below). His mother had moved from Meerut, where her first husband had been killed in action in 1857. Thousands of Europeans, mostly Britons, are buried in the twin towns. The Cantonment has adjacent Protestant and Catholic cemeteries, though due to overcrowding in the former, the latter has of late become non-denominational – they are managed by the same committee. In 1901, the town had a population of 1720, which climbed up to 3700 in the summers, when the heat of the Indian plains became unbearable.
