of captured European settlers, including perspectives of literate women captured by the indigenous peoples of North America, exist in some number. The writings of Mary Rowlandson, captured in the chaotic fighting of King Philip's War, are an example. Such narratives enjoyed some popularity, spawning a genre of the captivity narrative, and had lasting influence on the body of early American literature, most notably through the legacy of James Fenimore Cooper's The Last of the Mohicans. Some Native Americans continued to capture Europeans and use them both as labourers and bargaining chips into the 19th century; see for example John R. Jewitt, a sailor who wrote a memoir about his years as a captive of the Nootka people on the Pacific Northwest coast from 1802 to 1805. French Revolutionary wars and Napoleonic wars The earliest known purpose-built prisoner-of-war camp was established at Norman Cross in Huntingdonshire, England in 1797 to house the increasing number of prisoners from the French Revolutionary Wars and the Napoleonic Wars. The average prison population was about 5,500 men. The lowest number recorded was 3,300 in October 1804 and 6,272 on 10 April 1810 was the highest number of prisoners recorded in any official document. Norman Cross Prison was intended to be a model depot providing the most humane treatment of prisoners of war. The British government went to great lengths to provide food of a quality at least equal to that available to locals. The senior officer from each quadrangle was permitted to inspect the food as it was delivered to the prison to ensure it was of sufficient quality. Despite the generous supply and quality of food, some prisoners died of starvation after gambling away their rations. Most of the men held in the prison were low-ranking soldiers and sailors, including midshipmen and junior officers, with a small number of privateers. About 100 senior officers and some civilians "of good social standing", mainly passengers on captured ships and the wives of some officers, were given parole outside the prison, mainly in Peterborough although some further afield. They were afforded the courtesy of their rank within English society. During the Battle of Leipzig both sides used the city's cemetery as a lazaret and prisoner camp for around 6,000 POWs who lived in the burial vaults and used the coffins for firewood. Food was scarce and prisoners resorted to eating horses, cats, dogs or even human flesh.
