However, France, Russia, and England had now resolved to interfere on behalf of the Greeks, and when the Sultan refused to attend to them, a fleet, consisting of ships belonging to the three nations, was sent into the Mediterranean.  They meant to treat with the Turks, but the Turks and Greeks thought they meant to fight, and in the bay of Navarino a battle began, which ended in the utter destruction of the Turkish fleet.  Out of 120 ships, only 20 or 30 were left, and 6000 men were slain.  This was on the 20th of October, 1827, and the terrible loss convinced Ibrahim Pasha that no further attempt to keep the Morea was of any use, so he sailed away to Egypt, of which his father was then Viceroy for the Sultan, but which he and his son have since made into a separate kingdom.  It was in October, 1828, that the Peloponnesus thus shook off the Turkish yoke.
