The trial took place between 18 and 21 June 1945 with foreign press and observers from the United Kingdom and United States present. The date was chosen carefully to be at the same time as a conference on the creation of the Soviet-backed Polish puppet government was organized. The verdict was issued on 21 June, with most of the defendants coerced into pleading guilty by the NKVD. General Okulicki's witnesses for the defense were declared unreachable "owing to bad atmospheric conditions", and no evidence was offered during the trial. Of the sixteen defendants, twelve were sentenced to prison terms ranging from four months to ten years, while charges against the four others were dropped by the prosecution.
