The Sultan could count on bringing much larger and better-armed forces into the field

The Greeks were a minority of the population of the Ottoman Empire, comprising perhaps 3 million out of its 23 or 24 million people; only in a few areas - the Morea, the islands of the Aegean and some places north of the Gulf of Corinth - did they predominate. Yet even these figures ail to give a full sense of the imbalance, for whereas the Greeks had no cavalry and found it hard to raise and arm even 15,000-20,000 fighters, the Sultan could count on bringing much larger and better-armed forces into the field.
