[1] In order to break the siege of Acropolis, the British officers Admiral Lord Cochrane and General Richard Church, who were nominally commanding the Greeks, decided to make an assault against the Turkish camp under the command of Mehmed Reshid Pasha.

[3] 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.

All Souliotes and Cretans fell, 22 Philhellenes, 270 regular soldiers, hundreds of irregulars and the Greek chieftains Ioannis Notaras, Lampros Veikos, Georgios Drakos, Georgios Tzavelas and Tousias Botsaris were killed by the cavalry attack.

This defeat destroyed Greek morale and the only places on mainland Greece that persevered after the battle were Mani and Nafplio, seat of the government.
