What is "gawilghur"

Gawilghur (also Gawilgarh or Gawilgad) was a well-fortified mountain stronghold of the Maratha Empire north of the Deccan Plateau, in the vicinity of Melghat Tiger Reserve, Amravati District, Maharashtra. It was successfully assaulted by an Anglo-Indian force commanded by Arthur Wellesley on the 15 December 1803 during the Second Anglo-Maratha War. In popular culture, the campaign to take Gawilghur forms the background of the novel Sharpe's Fortress by Bernard Cornwell, the third in a series of books covering the eponymous hero's time in the British army in India during the Napoleonic era.
