This is a full transcription of a patriotic and civic prayer service offered on 29 October 1795 at the German Jews’ Synagogue in London, composed by chief Rabbi Moses Myers and translated into English by David Levi. The prayers on behalf of King George Ⅲ came in the aftermath of the unraveling of the “Popgun Plot,” an alleged 1794 conspiracy by three members of the London Corresponding Society to assassinate the kning by means of a poison dart fired from an airgun. Three members, Paul Thomas LeMaitre, John Smith, and George Higgins, were arrested in late 1794, and Robert Thomas Crossfield in December 1795. Ultimately, all four were acquitted of treason in May 1796, on the grounds that the chief witness against them was dead.
