After four years of futile efforts to stamp out the Greek revolution, it became clear to Sultan Mahmoud that his army, as then constituted, was unequal to the task. He was much impressed by the success of Mehemet Ali in Egypt in creating an army armed and drilled in the manner of European armies. In 1824, he called on this great vassal to aid in the reconquest of Greece by sending his new army and fleet there. Mehemet consented to do so, but only on the promise of the Sultan that Syria, Damascus, and Crete, would be added to his Pashalic. He sent his fleet to co-operate with that of the Sultan on the coast of the Morea. It sailed from Alexandria on July 25, 1824, with an army of ten thousand infantry and a thousand cavalry, under command of Ibrahim Pasha, the son of Mehemet Ali. They were landed at Modon and marched thence to Navarino. That fortress was garrisoned by sixteen hundred Greeks. The flower of the Greek army of seven thousand men advanced to relieve the fortress. Ibrahim with three thousand men attacked and utterly defeated them. The Greeks fled in wild confusion. This battle was proof that the best Greek troops were unable to encounter the well-disciplined Egyptians in a pitched battle. After the capture of Navarino, Ibrahim continued his reconquest of Greece with uniform success. The Greeks were exhausted by their long struggle against the Turks. They could offer but a very feeble resistance to this new and far more effective enemy. In April, 1826, the Egyptian army captured Missolonghi, causing a loss to the Greeks of four thousand men. Thence he gradually subdued the whole of the Morea. Later the cities of Corinth and Athens fell into the hands of the Turks, and on May 6, 1827, at a battle at Phalerum, in the neighbourhood of this last city, Reschid Pasha, in command of an Albanian army, defeated and dispersed the last army of the Greeks then in the field. The Greek Government was forced to remove from the mainland to the island of Poros. The whole of Greece then fell into anarchy. Though the Greek fleet continued to make a gallant stand against the combined Turkish and Egyptian fleets, it was not strong enough to maintain a mastery at sea and to cut off the communication between Ibrahim’s army and its base in Egypt. It is certain that if the Great Powers of Europe had not intervened, Greece would have been completely subdued, and Turkish rule would have been reinstated there. Ibrahim threatened to remove the whole Greek population and sell them into slavery, and to replace them by Egyptians and Arabs.
