Sharpe's Fortress (Richard Sharpe's Adventure Series #3)

Promoted for his gallantry in the war against India's rebellious Mahratta confederacy, Richard Sharpe is uncomfortable with his newfound authority -- and embroiled in his own private campaign. The unmistakable scent of treason is leading him to Gawilghur, an impenetrable fortress in the sky and the last refuge of desperate enemies of all dark stripes. And as the army of Sir Arthur Wellesley, the future Duke of Wellington, prepares to lay siege to the stronghold high above the Deccan Plain, Sharpe will risk his honor, reputation, and fortune on a battle that will test him as never before.
