Many members of this organization who played particular roles in the Armenian Genocide also participated in the Turkish national movement. The Special Organisation, which was made of especially fanatical Unionist cadres, was expanded from August 1914 onwards. Talaat Pasha, as the Interior Minister, gave orders that all of the prisoners convicted of the worse crimes, such as murder, rape and robbery, could have their freedom if they agreed to join the Special Organisation to kill Armenians and loot their property. Besides the hardened career criminals who joined in large numbers to have their freedom, the rank and file of Special Organisation killing units included Kurdish tribesmen attracted by the prospect of plunder and refugees from Rumelia, who were thirsting for the prospect of revenge against Christians after having been forced to flee from the Balkans in 1912. The recruitment of thuggish career criminals straight from the prison system into the Special Organisation explains the very high incidence of rape during the Armenian Genocide.
