Habsburg Sons describes Jewish participation in the Habsburg Army, 1788-1918, concentrating on their role in World War I. Approximately 300,000-350,000 Jews fought in the Austro-Hungarian Armies on all fronts. Of these, 30,000–40,000 died of wounds or illness, approximately 25,000 were officers. At least 17% were taken prisoner in camps all over Russia and Central Asia. Many soldiers were Orthodox Ostjuden, and soldiers came into regular contact with Jewish civilians. Over 130 Feldrabbiner (chaplains) served mainly on Eastern and Italian Fronts. Antisemitism was present but generally not overt. The book uses personal diaries and newspaper articles (most available in English for the first time) to describe their experiences. The comparative experiences of Jews in German, Russian, Italian Armies is also summarized.
