Topal Osman
Hacı Topal Osman Ağa (1883 – 2 April 1923) also known as Osman the Lame, was a Turkish officer, a militia leader of the National Forces, a volunteer regiment commander of the Turkish army during the Turkish War of Independence who eventually rose to the rank of lieutenant colonel, and was a perpetrator of the Armenian and Pontic genocides. Except the Greeks and Armenians, he also terrorised local Muslim population who opposed him. He was the commander of Mustafa Kemal's special Bodyguard Regiment. He showed usefulness in the War of Independence, but in 1923, when it was decided that he was the instigator of Trabzon Deputy Ali Şükrü Bey's murder, he was detained. He was captured and injured during clashes with military police, but he was killed by İsmail Hakkı Tekçe.
