Stanislas Saint Clair
Stanislas Graham Bower Saint Clair (24 January 1835 in Wieprze – 24 January 1887 in Ligneuville), nom de guerre Hidayet Pasha was a British officer, Polish-Lithuanian rebel, and later an Ottoman military officer of mixed Scottish and Polish-Lithuanian background.
He is most notable for an 1878 Muslim insurgence he organized in the Rhodope mountains in Principality of Bulgaria. The insurgence planned to attack Bulgarian civilians and forces of the Russian Empire in order to claim back to the Ottoman Empire the territories ceded to Principality of Bulgaria under the Treaty of San Stefano. The insurgence was defeated by the Imperial Russian Army and Captain Petko Voyvoda's detachment.
