The Greek Army burned and destroyed every single town, village, building and farm they could find while retreating. Not just burning, the Greek Army also directly killed thousands of Turkish (including Greek) civillians along with raping and torturing well over thousands.
Middle East historian, Sydney Nettleton Fisher wrote that: "The Greek army in retreat pursued a burned-earth policy and committed every known outrage against defenceless Turkish villagers in its path."
The overall casualty caused by the scorched-earth alone is estimated to be around 50.000 civillians, some dying during the event and some dying due to the poverty in the aftermath. Also, over 3 million animals were killed.
• The scale of the arson and destruction was so severe that over 35.000 buildings got destroyed.
• Over 300 towns and villages were either completely destroyed or burned.
• Over 3 million animals were killed.
İsmet Pasha's referendum about Greek devastations in Anatolia stated that 134,040 Horses, 63,926 Donkeys and Mules were killed or removed and the total amount of all animals including sheep, goats, cows, camels, oxen and buffaloes killed or removed were 3,291,335. Venizelos' reply on the same day did not include a contrary statement to the destruction of animals.
General Frangou wrote: "Greek soldiers escaping from Anatolia were able to escape as far as Çeşme with the horses they gathered from the villages. Their horses were also injured, bruised and skinny, some of them were scattered in the sea from hunger and thirst, and some of them were lying on the sand. Some of them were licking the damp stones on the dried fountain heads. Some of the poor animals were dead and some were about to die."
Ernest Hemmingway who witnessed the Greek withdrawal fron Edirne, states that "The Greeks were nice chaps too. When they evacuated they had all their baggage animals they couldn't take off with them so they just broke their forelegs and dumped them into the shallow water. All those mules with their forelegs broken pushed over into the shallow water. It was all a pleasant business. My word yes a most pleasant business."
—Out of approximately 18,000 buildings in the province of Manisa, fewer than 500 survived. Over 850 people were executed.
Colonel Stylianos Gonatas states that Manisa was burned by the retreating Greeks while keeping the Turkish inhabitants inside the city, not letting them leave the burning houses and mosques. He also adds that the destruction of properties by the Greek Army included even the houses of the Greek soldiers from Turgutlu.
—Turgutlu (Cassaba) lost roughtly 90% of the structures.
—Ataşehir lost over 4000 buldings, meaning that 80% of the town was destroyed.
Colonel Stylianos Gonatas states that *Every village in the plain east of Alaşehir was burned and that his troops could not find any living person nor anyone to take with them as a guide.*
—Uşak lost roughly 3,000 buildings, while Salihli lost 65% of its entire structural footprint.
Kinross wrote, "Already, most of the towns in its path were in ruins. One third of Ushak no longer existed. Alashehir was no more than a dark scorched cavity, defacing the hillside. Village after village had been reduced to an ash-heap. Out of the eighteen thousand buildings in the historic holy city of Manisa, only five hundred remained."
An officer of the Greek Army, Panagiotis Demestichas, who in his memoirs he writes the following: "The destruction in the cities and villages through which we passed, the arsons and other ugliness, I am not able to describe, and I prefer that the world remains oblivious to this destruction."
