1822–1824 Greek civil wars of 1824–1825 Egyptian intervention (1825–1826) Great powers intervention (1827–1829) The Battle of Peta or Battle of Petta was fought between the Greeks (with Philhellenes) led by Alexandros Mavrokordatos with Markos Botsaris and the Ottomans led by Omer Vrioni on 16 July 1822 (4 July Julian calendar).

[3] After the Souliotes defeated the forces of Khourshid Pasha in May and June 1822, they joined Prince Alexander Mavrocordatos who landed at Missolonghi with a contingent of Greek regulars.

At the same time, however, Khourshid Pasha surrendered command of the Ottoman forces in Epirus to the Albanian general Omer Vrioni.

[4] Joining the Greeks were one battalion of German, Polish, Swiss, French and Italian philhellene volunteers with Karl von Normann-Ehrenfels, formerly of the Württemberg army, serving as Mavrokordatos's chief of staff.

[8] Mavrokordhatos placed his men on two ridges to the west and east of the village of Peta, which stands on a low hill at the beginning of a coastal plain.

[15] Attacked from both sides, the forces on the lower ridge were overwhelmed with most of the philhellenes and Greek regulars, who were now disorganized and out of formation making a desperate last stand against the Ottoman cavalry who cut them down without mercy.
