The immediate objects of Orchan’s ambition, on his accession, were the Greek cities of Nicæa and Nicomedia, with their surrounding districts, the last important possessions of the Byzantine Empire in Asia. Nicæa was then a great city. It had attained greater importance during the sixty years when the Latins were in occupation of Constantinople and the Greek Emperors were relegated to Asia and made it their capital. It was well fortified. It could only be captured, as Brusa had been, by cutting off its communications with Constantinople, and depriving its people of the means of subsistence. The Greek Emperor, Andronicus III, made an effort to relieve it. He hastily raised an army of mercenaries, in 1326, and led them across the Bosphorus. He fought a battle against Orchan at Pelecanon, on the north shore of the Gulf of Nicomedia. According to the Greek historians, the Ottomans had much the worst of it, losing a great number of men, while the losses of the Greeks were trivial. However that may have been, Andronicus decided on a retreat. But a scrimmage occurred in the night between his bodyguard and the enemy, in which the Emperor himself was slightly wounded. He thereupon fled precipitately, and was conveyed in a litter to the Bosphorus and thence to Constantinople. His army, dispirited by this abandonment by their Emperor, was defeated and dispersed. As a result, Nicæa surrendered in the following year, 1327, on favourable terms. The majority of its garrison and citizens followed the example of those of Brusa and adopted Islam. Very few availed themselves of the offer to transfer themselves to Europe. This ill-starred campaign and cowardly flight of Andronicus was the last effort of the Byzantine Emperors to save their possessions in Asia. What remained of them, chiefly the city of Nicomedia, were left to their own resources, without further aid from Europe. Nicomedia was well fortified and was apparently a tough job for the Ottomans, for it held out till 1337, or possibly 1338, and eventually surrendered in the same way, and on the same terms, as Brusa and Nicæa.
