Analysis of information sources in references of the Wikipedia article "Siege of Tripolitsa" in English language version.
The fall of the Turkish fortress of Tripolitsa in the central Morea on October 5, 1821, brought the single worst massacre of the war. ... At least 8,000 Muslims and Jews died at Tripolitsa alone.
One of the worst atrocities, in terms of ferocity and number of victims, took place after the fall of Tripolitsa in September 1821. In the words of Alison Phillips: "the other atrocities of the Greeks paled before the awful scenes which followed the storming of Tripolitsa." In the heart of Morea, home to the Ottoman pasha (governor) of the region, Tripolitsa was estimated to have a population of 15,000 people before the Greek revolution that included 7,000 Muslims and 1,000 Greek-speaking (Romaniote) Jews. With the start of the revolution most of the Orthodox Christians fled the town, and the Muslims of the surrounding regions of Mistras, Bardounia, Leondari and Fanari, along with 9,000 Muslim troops, sought protection inside the walls of the citadel. It is estimated that approximately 25,000 souls were inside the citadel in the summer of 1821. Famine, disease, and fighting had thinned the population, yet it is believed that approximately 8,000 Muslims of every age and sex, but mostly women and children, perished when the Greeks sacked the citadel.
