Terror and lamentation were in his train ; before him nations bowed down in the dust . He advanced victoriously , made himself master of Aleppo , and marched on to storm the sacred El-Kahera , which they now call Cairo . The Mamelukes defended themselves long and desperately , until they at last succumbed to superior numbers . `` But tranquillity was not yet restored to Egypt ; the Mameluke prince , Tournan Bey , stole into the city at midnight , and with his Mamelukes murdered the entire Turkish garrison . Filled with wrath the great Selim returned and laid siege to the city . It held out for thirteen days and nights , but after fierce struggles was at last compelled to yield . Selim punished them terribly ; they were all made prisoners , and Tournan was hanged in the midst of the city .
