Ismael Pacha (1813–65), also known as György Kmety, fought against the Russians in the 1848 Hungarian Revolution. After its failure and the harsh Russian reprisals, he joined the Ottoman army. Fenton took a series of photographs of Ismael Pacha receiving a pipe from his servants. Both Ismael Pacha and his Nubian servant (seen in a photograph nearby) appear in Barker's painting The Allied Generals.
