White Slaves. — In Egypt there are white slaves and slaves of colour. […] There are also some Greeks who were taken in the War of Independence. […] In like manner in Egypt, the officers of rank are for the most part enfranchised slaves. I have seen in the bazars of Cairo Greek slaves who had been torn from their country, at the time it was about to obtain its liberty; I have seen them afterwards holding nearly all the most important civil and military grades; and one might be almost tempted to think that their servitude was not a misfortune, if one could forget the grief of their parents on seeing them carried off, at a time when they hoped to bequeath to them a religion free from persecution, and a regenerated country.
At the request of Sultan Mahmud II (1803-39), Muhammed Ali sent the Egyptian army to subdue a Greek revolt. In 1823 the re-attachment of Crete to the pashlik of Crete created a base from which to attack the Greeks. Egyptian troops led by Ibrahim Pasha, the adopted son of Muhammad Ali, proceeded to devastate the island completely; villages were burned down, plantations uprooted, populations driven out or led away as slaves, and vast numbers of Greek slaves were deported to Egypt. This policy was pursued in the Morea where Ibrahim organized systematic devastation, with massive Islamization of Greek children. He sent sacks of heads and ears to the sultan in Constantinople and cargoes of Greek slaves to Egypt.
