The Sultan had thrown his whole land force into the Greek mainland. Khurshid, after his defeat of Ali Pasha, marched to Larissa, in Thessaly. Thence two armies, 50,000 strong, under Bramali and Homer Brionis converged upon the Morea. In the face of so formidable an invasion, Maurokordatos took the field himself. He mismanaged things badly. At Arta he sacrificed his choicest regiment, the famous corps of Philhellenes, composed of foreign officers and commanded by men who had won distinction in Napoleon's campaigns. They were cut down almost to a man. Maurokordatos fell back to Missolonghi. In the meanwhile Dramalis with 25,000 foot and 6,000 horse penetrated into the Morea. The Greek Government at Argos dispersed. All would have been lost for the Greeks had Dramalis not neglected to cover the mountain passes behind him. While he marched on to Nauplia, the Greek mountaineers rose behind him. Demetrios Ypsilanti, the acting-president of Greece, with a few hundred followers threw himself into Argos. There he held the Acropolis against the Turkish rearguard. Kolokotrones, calling out the last men from Tripolitza, relieved Ypsilanti at Argos. The mountain passage was seized. Dramalis had to give up his conquest of the Morea, and fight his way back to the Isthmus of Corinth. Without supplies and harassed by hostile peasant forces the Turkish army became badly demoralized. Thousands were lost on the way. Dramalis himself died from over-exposure. The remainder of his army melted away at Corinth under the combined effects of sickness and drought.
A decisive turn in the Greek war for independence was reached. Europe realized that the revolt had grown to the proportions of a national war. Popular sympathy in Russia became more clamorous. Capodistrias, the Russian Prime Minister, rightly measured the force of this long pent-up feeling. Unable to move the Czar, who still floundered in the toils of the Holy Alliance, Capodistrias withdrew from public affairs and retired to Geneva.
