1649, a version of the "Agreement of the People" that had been drawn up in October 1647 for the Army Council and subsequently modified was presented to the House of Commons. At the end of January 1649, Charles I of England was tried and executed for treason against the people. In February, the Grandees banned petitions to Parliament by soldiers. In March, eight Leveller troopers went to the commander-in-chief of the New Model Army, Thomas Fairfax, and demanded the restoration of the right to petition. Five of them were cashiered out of the army. In April, 300 infantrymen of Colonel John Hewson's regiment, who declared that they would not serve in Ireland until the Levellers' programme had been realised, were cashiered without arrears of pay. This was the threat that had been used to quell the mutiny at the Corkbush Field rendezvous. Later that month, in the Bishopsgate mutiny, soldiers of the regiment of Colonel Edward Whalley stationed in Bishopsgate London made demands similar to those of Hewson's regiment; they were ordered out of London. When they refused to go, 15 soldiers were arrested and court martialed. Six of their number were sentenced to death. Of these, five were later pardoned, while Robert Lockyer (or Lockier), a former Levellers agitator, was hanged on 27 April 1649. "At his burial a thousand men, in files, preceded the corpse, which was adorned with bunches of rosemary dipped in blood; on each side rode three trumpeters, and behind was led the trooper’s horse, covered with mourning; some thousands of men and women followed with black and green ribbons on their heads and breasts, and were received at the grave by a numerous crowd of the inhabitants of London and Westminster." In 1649, Lieutenant-Colonel John Lilburne, William Walwyn, Thomas Prince, and Richard Overton were imprisoned in the Tower of London by the Council of State (see above). It was while the leaders of the Levellers were being held in the Tower that they wrote an outline of the reforms the Levellers wanted, in a pamphlet entitled "An Agreement Of The Free People Of England" (written on 1 May 1649). It includes reforms that have since been made law in England, such as the right to silence, and others that have not been, such as an elected judiciary. Shortly afterwards, Cromwell attacked the "Banbury mutineers", 400 troopers who supported the Levellers and who were commanded
