Colonel Edward Sexby (or Saxby; 1616 – 13 January 1658) was an English Puritan soldier and Leveller in the army of Oliver Cromwell. Later he turned against Cromwell and plotted his assassination. Biography Sexby was born in Suffolk in 1616, but little else is known about his life before the English Civil War. Reportedly he was a son of a gentleman, had been apprenticed as a grocer in London, and may have had family connections to Cromwell. In 1643 he was a trooper in Cromwell's Roundhead cavalry regiment (nicknamed the Ironsides). In 1647, being still a private in the same regiment, which was then commanded by Sir Thomas Fairfax, he took a leading part in the movement against disbanding the army, and was one of the three soldiers charged with the letter from the army to their generals which Skippon brought before the House of Commons on 30 April 1647.

But it seems now, except a man hath a fixed estate in this kingdom, he hath no right in this kingdom. I wonder we were so much deceived ... I shall tell you in a word my resolution. I am resolved to give my birthright to none. His contributions irritated Cromwell, who complained: "I confess I was most dissatisfied with that I heard Mr Sexby speak, of any man here, because it did savor so much of will." His speeches were vigorous and effective, opposing all compromise with King Charles I and demanding the immediate establishment of manhood suffrage. He may have been involved in the capture of the king at Holdenby House in 1647. Sexby appears to have left the army about the close of 1647, but happening to be present at the Battle of Preston, with a letter from the Levellers leader John Lilburne to Cromwell, he
