of the army in Lilburne's draft of the Agreement of the People. Second imprisonment On 28 March 1649, he was arrested, with Lilburne and two other leaders of the Levellers, as one of the authors of England's new Chains Discovered. A refusal to acknowledge the authority of the Council of State or to answer their questions, caused his committal to the Tower. In conjunction with three fellow-prisoners he issued, on 1 May 1649, the Agreement of the Free People of England, followed on 14 April by a pamphlet denying the charge that they sought to overthrow property and social order. Release On his own account he published on 2 July 1649 a Defiance to the government, in the form of a letter addressed to the citizens usually meeting at the Whalebone in Lothbury, behind the Royal Exchange, a place which was the headquarters of the London Levellers. The failure of the government to obtain a verdict against Lilburne involved the release of his associates, and on 8 November Overton's liberation was arranged. The only condition was that he should take the engagement to be faithful to the Commonwealth, which he probably had no hesitation in doing. In September 1654 Overton proposed to turn spy, and so offered his services to Thurloe for the discovery of plots against the Lord Protector's government. In the following spring he was implicated in the projected rising of the Levellers, and fled to Flanders in company with Lieutenant-colonel Sexby. There, through the agency of Sir Marmaduke Langdale (afterwards Lord Langdale), he applied to Charles II, and received a royal commission. Some months later he returned to England, supplied with Spanish money by Sexby, and charged to bring about an insurrection. Later life Overton's later history is obscure. He was again in prison during December 1659, and his arrest was ordered on 22 October 1663, for apparently printing something against the government of Charles II. Works It is difficult to give a complete list of Overton's works, as many are anonymous. The chief are the following: Monopolists as Frogs and Vermin, 1641. New Lambeth Fair newly Consecrated, wherein all Rome's Relics are set at sale (a satire in verse), 1642. Articles of High Treason exhibited against Cheapside Cross, with the last Will and Testament of the said Cross (a satire in verse), 1642. Man's Mortality, Amsterdam, 1643; a second and enlarged edition was published in 1655,
