Leyla Neyzi has published a study of the diary of Yaşar Paker, a member of the Jewish community of early 20th century Ankara who was drafted to the Labour Battalions twice, first during the Greco-Turkish War (1919-1922) and then again during World War II, a war in which Turkey did not take part. Neyzi's paper on the basis of Paker's diary published by Jewish Social Studies presents an overall picture for the conditions in these battalions, which were composed entirely of non-Muslims.[7]
