Many Jews throughout the country joined the army to fight for their fatherland; among them, Adolf Hübsch, subsequently rabbi at New York City; Solomon Marcus Schiller-Szinessy, afterward lecturer at the University of Cambridge; and Ignatz Einhorn, who, under the name of "Eduard Horn," subsequently became state secretary of the Hungarian Ministry of Commerce. The rebellious Serbians slew the Jews at Zenta who sympathized with Hungary; among them, Rabbi Israel Ullmann and Jacob Münz, son of Moses Münz of Óbuda The conduct of the Jewish soldiers in the Hungarian army was highly commended by Generals Klapka and Görgey. Einhorn estimated the number of Jewish soldiers who took part in the Hungarian Revolution to be 20,000; but this is most likely exaggerated, as Béla Bernstein enumerates only 755 combatants by name in his work, "Az 1848-49-iki Magyar Szabadságharcz és a Zsidók" (Budapest, 1898).
