The first task which imposed itself upon Orkhan was the subjection of Nicaea and Nicomedia. Just as the walls of Brusa had defied him to the end, those of Nicomedia and Nicaea were equally impregnable to the kind of army he could assemble. Whether it was that neither Byzantine nor Turk nor Slav nor Bulgarian were of the stock who would spend themselves scaling walls and battering down gates, or that the weapons of those days were more favourable for the purpose of defence than of assault, cannot be determined. But the curious fact remains that during this century there are few instances of cities taken by storm. Captures were effected for the most part by capitulation or by treachery.
Complete investment and consequent threatened starvation did not occur in the case of Brusa. Nor did Nicaea and Nicomedia surrender from starvation. This is the place, rather than at the end of the last chapter, to give two of the long list of reasons for surrender which Neshri puts into the mouth of the commandant and the leading citizens of Brusa.[94] For they state equally plainly and convincingly the case of Nicaea and Nicomedia.
The economic reason was that the inhabitants saw the Osmanlis settling themselves in all the country round about the three cities, and undisturbed in their permanent occupation of these regions by any aggressive movement from Constantinople. Nicomedia, although advantageously located for commerce, was not a port of call on the great trade route. It depended for its well-being upon an unrestricted communication with the interior. Brusa and Nicaea were manufacturing cities, whose prosperity was due to the use of raw materials produced in the vicinity, and to the ability to market the manufactured products. While food was still procurable, trade and business languished. When the Greeks saw that the Osmanlis had come in their midst to remain, and were not mere raiders like the Seljuk Turks, they realized that the alternative to submission was ruin.
The moral reason I have already touched upon in relation to Brusa. If there had been any hope of relief from the intolerable economic conditions under which they were living, the Nicaeans and Nicomedians might have resisted indefinitely, and maintained a gallant struggle for love of God and country. Their successful resistance, continued through many weary years, is a remarkable testimony to their religious zeal and to their patriotism. It was not until they felt themselves deserted by their brothers of blood and religion that they finally yielded. The Osmanlis did not prevail over them in battle. Their walls were not stormed. Their gates held fast. They were not starved out. They were abandoned by the Byzantines. So they became Osmanlis.
