With 60 others, he was arrested at a religious meeting in London in January 1641 at the house of Richard Sturges. He was a prisoner of war in 1642 in Oxford Castle, and wrote a pamphlet on the terrible conditions of his confinement, against William Smith.
He was an officer in the parliamentary New Model Army, in 1646 a Lieutenant and intelligence officer in Whalley's Regiment. He was on the army's General Council in 1647, and a supporter of the Levellers.
Jason Peacey writes of
|“||…informal networks of Puritan activists on the radical Protestant fringe … who were particularly involved in the advancement and propagation of particular religious visions, and explicitly concerned with spreading their message through the medium of print and through ‘conspiratorial’ publications. This circle included John Lilburne, Samuel Richardson, Edmund Chillingworth, and John Vicars.||”|
