Broken in health, Jastrow, with his family, spent the spring and summer of 1862 in Breslau, Berlin, and Dresden; in the autumn he accepted a call from the Jewish community in Mannheim. A few weeks later, Nov., 1862, the order for his expulsion was revoked, and gave occasion for a controversy between the congregation at Warsaw (which had continued his salary until he went to Mannheim) and that of Mannheim; at Jastrow's request the latter released him. A few months after his return to Warsaw (Jan. 1863) the revolution broke out. During its progress, and while Jastrow was traveling, his Prussian passport was canceled, and he was not permitted to return to Warsaw.
