An Impeachment of High Treason against _Oliver Cromwel_, and his son-in-law _Henry Ireton_, Esquires, late Members of the late forcibly dissolved House of Commons, presented to publique view; by _Lieutenant Colonel John Lilburn_, close prisoner in the Tower of London, for his real, true, and zealous affections to the Liberties of his Native Country. In which following Discourse or Impeachment, he engageth upon his life, either upon the principles of Law (_by way of indictment, the only and alone legall way of all tryals in England_) or upon the principles of Parliaments ancient proceedings, or upon the principles of reason (_by pretence of which alone they lately took away the King's life_) before a legal Magistracy, when there shall be one again in _England_ (_which now in the least there is not_) to prove the said _Oliver Cromwel_ guilty of the highest Treason that ever was acted in England, and more deserving punishment and death then the 44 Judges hanged for injustice by _King Alfred_ before the Conquest; or then the Lord _Chief Justice Wayland_ and his associates tormented by Edw. I. Or, then Judge _Thorpe_, condemned to dye for Bribery in Edw. 3. time; Or, then the _two dis-throned Kings_ Edw. 2. _and_ Rich. 2. Or, then the Lord Chief Justice _Tresillian_, (_who had his throat cut at Tyburn as a Traitor in Rich. 2. time, for subverting the Law_) and all his associates; Or, then those two grand Traytorly subverters of the Laws and Liberties of England, _Empson_ and _Dudley_, who therefore as Traytors lost their heads upon Tower-hill, in the beginning of Henr. 8 raign; Or, then trayterous Cardinal _Wolsey_, who after he was arrested of Treason, poysoned himself; Or, then the late trayterous _Ship-Money Judges_, who with one Verdict or Judgment destroyed all our propertie; Or, then the late trayterous Bishop of _Canterbury_, Earl of _Strafford_, Lord-Keeper _Finch_, Secretary _Windebanck_, or then Sir _George Ratcliff_, or all his Associates; Or, then the two _Hothams_, who lost their heads for corresponding with the Queen, &c.; Or, then the late King _Charls_ whom themselves have beheaded for a _Tyrant_ and _Traytor_. In which are also some Hints of Cautions to the Lord Fairfax, for absolutely _breaking his solemn Engagement with his souldiers_, _&c._, to take head and to regain his lost Credit in acting honestly in time to come; in helping to settle the Peace and Liberties of the Nation, which truly, really, and lastingly can never be done, but _by establishing the principles of the Agreement of the Free People_; that being really the peoples interest, and all the rest that went before, but particular and selvish. In which is also the Authors late Proposition sent to Mr. Holland, June 26. 1649, to justifie and make good at his utmost hazard (upon the principles of _Scripture, Law, Reason, and the Parliaments and Armies ancient Declarations_) his late actions or writings in any or all his Books.
