two of the ring-leaders were shot in Broken Hayes. In May 1651 Ingoldsby's regiment left Oxford and joined the army which fought at the Battle of Worcester the last battle of the English Civil War. Parliamentary career Ingoldsby was chosen as one of the Council of State in November 1652. He was elected MP for Buckinghamshire in 1654 for the First Protectorate Parliament and 1656 for the Second Protectorate Parliament. He sat in the second house of Parliament commonly known as Cromwell's Other House in 1657–1659. When Oliver Cromwell died in 1659, Ingoldsby supported Richard Cromwell as Lord Protector when the officers of the army began to agitate against Richard Cromwell.

On 22 April Ingoldsby met Lambert's forces near Daventry, arrested him as he tried to flee, and brought him in triumph to London. Ingoldsby was thanked by the House of Commons on 26 April 1660. He was elected Member of Parliament for the constituency of Aylesbury in early 1660 in the Convention Parliament. After the Restoration Ingoldsby was pardoned for his regicide, firstly for his activities in support of General Monck, and secondly because he pleaded that he had been forced to sign the death warrant by his cousin Oliver Cromwell, in that "he refused but Cromwell and the others held him by violence; and Cromwell, with a loud laugh, taking his hand in his, and putting the pen between his fingers, with his own hand wrote Richard Ingoldsby".
