The Battle of Phaleron or Battle of Analatos took place on 6 May (O.S.: 24 April ) 1827, during the Greek War of Independence. The Greek rebel forces were being besieged inside the Acropolis of Athens by Ottoman forces under the command of Mehmed Reshid Pasha. Greek forces outside the city were desperately trying to break the siege.
Two days before the battle, on 22 April 1827, Georgios Karaiskakis, the general of Central Greece, was fatally wounded in a minor clash with the Ottomans. He perished one day later, and his sudden death seriously damaged Greek morale and emboldened the Turks.
In total, the Greeks lost either 1,500 or 2,000 men, which was a devastating setback. The Battle of Phaleron was seen as the greatest Greek defeat in the Greek War of Independence. The men in the Acropolis surrendered on 5 June
