It is July 1809. During the Talavera Campaign, Sir Arthur Wellesley's army has entered Spain to confront Marshal Victor. Richard Sharpe and his small group of thirty riflemen, separated from their regiment during the retreat from Corunna, are attached to the newly arrived South Essex Regiment. Commanded by the cowardly and bullying Lieutenant Colonel Sir Henry Simmerson, the South Essex is a raw, inexperienced unit that has been drilled mercilessly with frequent use of the lash.
