The Jews of Warsaw participated in all street manifestations and political processions which took place during the year 1860-1861. Among those pierced by Cossack bullets during the manifestation of February 27, 1861, were several Jews. The indignation which this shooting down of defenceless people aroused in Warsaw is generally regarded as the immediate cause of the mutiny. Rabbi Meisels was a member of the deputation which went to Viceroy Gorchakov to demand satisfaction for the blood that had been spilled. In the demonstrative funeral procession which followed the coffins of the victims the Jewish clergy, headed by Meisels, marched alongside of the Catholic priesthood. Many Jews attended the memorial services in the Catholic churches at which fiery patriotic speeches were delivered. Similar demonstrations of mourning were held in the synagogues. An appeal sent out broadcast by the circle of patriotic Jewish Poles reminded the Jews of the anti-Jewish hatred of the Russian bureaucracy, and called upon them "to clasp joyfully the brotherly hand held forth by them (the Poles), to place themselves under the banner of the nation whose ministers of religion have in all churches spoken of us in words of love and brotherhood." The whole year 1861 stood, at least as far as the Polish capital was concerned, under the sign of Polish-Jewish "brotherhood." At the synagogue service held in memory of the historian Lelevel Jastrow preached a patriotic sermon. On the day of the Jewish New Year prayers were offered up in the synagogues for the success of the Polish cause, accompanied by the singing of the national Polish hymn _Boze cos Polske_. [1] When, as a protest against the invasion of the churches by the Russian soldiery, the Catholic clergy closed all churches in Warsaw, the rabbis and communal elders followed suit, and ordered the closing of the synagogues. This action aroused the ire of Lieders, the new viceroy. Rabbi Meisels, the preachers Jastrow and Kramshtyk as well as the president of the "Congregational Board" were placed under arrest. The prisoners were kept in the citadel of Warsaw for three months, but were then released.
