On investigating the matter on the spot, they discovered the machinations of the over-zealous officials and apostasized informers who had represented a street quarrel as an organized uprising.

The new commission of inquiry, of which one of the St.Petersburg commissioners, Count Trubetzkoy, was member, disclosed the fact that the Jewish community as such had had nothing whatsoever to do with what had occurred.

The findings of the commission resulted in an "Imperial Act of Grace": the imprisoned Jews were set at liberty, the penal conscripts were returned from service, several local officials were put on trial, and the governor of Moghilev was severely censured.
This took place in November, 1844, after the Mstislavl community had for nine long months tasted the horrors of a state of siege.

The synagogues were filled with Jews praising God for the relief granted to them.

The community decreed to commemorate annually the day before Purim, on which the ukase inflicting severe punishment on the Jews of Mstislavl was promulgated, as a day of fasting and to celebrate the third day of the month of Kislev, on which the cruel ukase was revoked, as a day of rejoicing.
