The incident occurs in Book X of Clarendon's History of the Rebellion, where it is dated 3 June 1647; on the engraving, by Dupuis in reverse, the date is given as 4 June. The caption to the engraving gives the story of the incident, which happened after the falling out of Parliament and the Army, now dominated by 'Fanaticks' such as Fairfax and Ireton and Harrison. The King had been placed in one of his own houses, Holmby House, but it was situated in a Parliamentary part of Northamptonshire. 'Cornet Joyce came with a detachment of fifty Horse from the Army about break of day, & without any interruption from the Guards which were upon duty there, went up with two or three Troopers & Knock'd at the Kings Chamber door, whereupon his Majesty rose out of Bed, and half undress'd order'd the door to be open'd and Cornet Joyce with his Troopers enter'd the Room with their hats off and pistols in their hands, and Joyce told the King he must go with him to the Army; His Majesty demanded by what Authority they came, Joyce answer'd By this and and shew'd Him his Pistol ...'. Cornet George Joyce was originally a tailor in London. He died sometime after 1670, probably in Holland, where he took refuge after the Restoration.
