The most direct and definite expression of Philhellenism during the Greek War of Independence (1821–9) was military action by European volunteers, generally officers, on the side of the revolutionaries. This article discusses the Philhellenes’ military action at the Battle of Peta in 1822, as recorded in the diary of one of the few survivors, the physician Johann-Daniel Elster. Elster's information is compared with other Greek and European sources about the battle and the conditions of the campaign in Epirus and the circumstances that led to the Philhellenes’ defeat re-evaluated.
