Alfred De Dreux's Guerrier Ottoman a Cheval will lead Christie's 19th Century European Art Sale on November 26 in London.
The painting, one of just a handful of orientalist paintings by De Dreux, carries an estimate of £300,000-500,000 ($480,300-800,500) and depicts a mounted Ottoman soldier firing a pistol.
De Dreux (1810-1860) painted historical scenes and portraits, which were immensely popular during his lifetime.

He was best known for his equestrian paintings, and as a result of his success he received commissions from aristocratic families across Europe, where he travelled widely.
He was a favoured painter of both Louis-Phillipe and Napoleon III.
A work titled "African groom holding a stallion, with a dog" holds De Dreux's record, achieving £848,000 ($1.6m) at Christie's London in May 2006.
Bedroom, Strandgade 30, a painting by Danish artist Vilhelm Hammershoi (1864-1916), carries an estimate of £250,000-350,000 ($400,250-560,350).
A deceptively complex composition, featuring a corner of the artist's bedroom in Copenhagen, the painting displays a masterly handling of light and composition.
Best known for his melancholy, mysterious paintings, Hammershoi projects a sense of unease and dissonance into his work - giving them an unearthly feel.
In 2012, his Ida Laeser et Brev (Ida Reading a Letter) realised £1.7m ($2.7m) at Sotheby's in London, a record price for the artist's work.
We have this letter signed by Hammershoi's contemporary, Claude Monet.
