Hessayon speculates that he may have been captured by the Royalists as there is no record of him until May 1647 when an ensign by the name of William Everard signed a petition voicing the grievances of the army under the command of Sir Thomas Fairfax.
In 1648 he was briefly imprisoned in Kingston, Surrey, for causing a disturbance, and Gerrard Winstanley wrote Truth Lifting up its Head above Scandals in his defence.
They appeared before him on 20 April and famously refused to remove their hats in his presence (an act that, at that time, was seen as showing a lack of respect for his authority).
They justified their commune's actions to him using the same arguments as they presented in the Diggers first manifesto, The True Levellers Standard Advanced,[7] which was published around the same date.
He was not the only one so detained and the end of December it was reported "many of Ranting Everard's party are lunatick, and exceedingly distracted; they talk very high against the Parliament, and this present Government; for which some of them have received the lash".
