A 1381 court record names a woman as “chief perpetrator and leader” of the mob that killed the Archbishop of Canterbury. She was acquitted.
On 13–14 June 1381, during the Peasants’ Revolt, a mob burned down the Savoy Palace, the London residence of John of Gaunt, the most powerful man in England. They stole a fortune, burned a second building at Clerkenwell, then dragged the Archbishop of Canterbury and the royal Treasurer out of the Tower of London and had them beheaded.
The jury indictment for this survives today at the National Archives (KB 27/482), and it doesn’t name a mob leader you’d expect. It names Joanna Ferrour, a woman from Rochester, Kent, as the “chief perpetrator and leader” of the whole sequence. Her husband is only mentioned as an identifier (“wife of John Ferrour”). He’s not even listed as an accused participant in this particular roll.
She was arrested and tried. The jury found her not guilty. She walked free on the surety of four men who vouched for her.
A second, separate indictment (KB 27/485) does name her husband John as a co-accused in the same events. Why two different juries produced two different versions of who led what is genuinely unresolved. It could be different stages of process, or overlapping local accusations. Nobody currently knows.
There’s one more thread that never quite resolves. In 1400, a “John Ferrour of Southwark” was pardoned by King Henry IV specifically for saving Henry’s life during that same attack on the Tower in 1381, when Henry was a teenager sheltering inside. Whether that’s the same John Ferrour from Rochester is impossible to prove from the surviving record, but the coincidences (the alias, the Southwark connection, the unusually long delay before Rochester-John was finally cleared) are hard to ignore.
