The trial lasted 45 days, and saw one hundred witnesses testify on behalf of the prosecution and defence. On 14 August 1975, the jury retired to consider their verdicts. These deliberations continued until the following day. On the afternoon of 15 August, having deliberated for over six-and-a-half hours, the jury returned unanimous guilty verdicts in relation to the 21 murder charges against the Birmingham Six. Upon passing sentence, Judge Nigel Bridge informed the defendants: "You stand convicted of each of 21 counts, on the clearest and most overwhelming evidence I have ever heard, of the crime of murder." All six men were sentenced to life imprisonment. None of the Birmingham Six displayed any emotion upon hearing the verdict, although William Power saluted the judge.
