Extracts from The Life of Edward Earl of Clarendon (published 1759)
Part 1 Pages 78-80

He (Hyde) was in charge of many committees made upon private complaints. Insomuch as he was seldom in the Afternoon free from that service in the Committees as he was never absent in Mornings from the House and he was often heard to mention one private Committee (in which he was accidentally put in the chair) upon an inclosure which had been made of great wastes belonging to the Queens manors (principally Somersham)without the consent of the tenants, the benefit whereof had been given by the Queen to a servant of near Trust who forthwith sold the lands inclosed to the Earl of Manchester, Lord Privy Seal, who together with his son Mandevil, were now most concerned to maintain the inclosure, against which as well as the inhabitants of other manors who claimed Common on those wastes, as the Queens tenants of the same, made loud complaints as a great Oppression carried upon them with a very high hand and supported by power.
The committee sat in the Queen’s Court and Oliver Cromwell being one of them appeared much concerned to countenance the Petitioners, who were numerous, together with their witnesses, the Lord Mandevil being likewise present as a Party and by the direction of the Committee sitting covered. Cromwell (who had never before been heard to speak in the House of Commons) ordered the witnesses and Petitioners in the Method of Proceeding and seconded and enlarged upon what they said with great passion; and as these witnesses and persons concerned who were a very rude kind of people, interrupted the council and witnesses of the other side with great clamour when they said any thing that did not please them, to that Mr Hyde (whose office it was to oblige men of all sorts to keep order) was compelled to use some sharp Reproofs and some threats to reduce them to such a Temper that the business may be quietly heard.
Cromwell in great fury reproached the Chairman for being partial and that he discountenanced the witnesses by threatening them, the Other (ie Hyde) appealed to the Committee which justified him and declared that he behaved himself as he ought to do; which more inflamed him (ie Cromwell) who was already much too angry. When upon any mention of matters of fact, or the proceeding before and at the inclosure, the Lord Mandevil desired to be heard, and with great modesty related what had been done or explained what had been said, Mr Cromwell did answer and reply upon him with so much Indecency and Rudeness and in language so contrary and offensive that every man would have thought that as their natures and their manners were as opposite as it is possible, so their interests could never have been the same (in fact Manchester, Mandevil and Cromwell would within two years be fighting together against the King). In the end his whole carriage was so tempestuous and his behaviour so insolent that the Chairman found himself obliged to reprehend him and to tell him if he proceeded in the same manner he would presently adjourn the Committee and the next morning complain to the House of him; which he never forgave and took all occasions afterwards to pursue him with the utmost malice and revenge to his death.
