Charles I of England fled from
Hampton Court on 11 November 1647, apparently with the intention of crossing to the Isle of Wight and Hammond, for safety and as a staging post to leaving the country. Hammond had been introduced to the King earlier, at an audience where he made such protestations of loyalty that Charles came to believe him sympathetic. According to
Anthony Wood, it was
Henry Hammond, Robert Hammond's uncle, who brought him to the king. The actual circumstances of the escape are known largely through the later accounts of the royalist proponents of the plan.
John Ashburnham (on his own account) met Hammond as he was going down to his new post, and heard that he went there "because he found the army was going to break all promises with the king, and that he would have nothing to do with such perfidious actions". On 13 November 1647 Hammond learnt from
Sir John Berkeley and Ashburnham that the king had fled from Hampton Court to save his life from the
Levellers, and intended to put himself under Hammond's protection. Hammond said that he was undone, and between his duty to the king and his obligations to the army would be confounded. Finally, he gave a vague promise to act with honour. Ashburnham took Hammond to the king on the mainland, and the king came to the Isle of Wight. Hammond at once wrote to the parliament announcing what had happened; and called the gentlemen of the island together, requiring their co-operation for the defence of his majesty's person. Parliament then drew up a series of instructions to Hammond, ordering him to set a guard over Charles and keep him on the island; a second set of instructions came, on the occasion of the
Treaty of Newport, dated 17 August 1648. He was also ordered by the commons to send up Ashburnham, Berkeley, and
William Legge as prisoners, and, under protest, obeyed. Thus instead of becoming the king's protector, Hammond found himself his gaoler. His relations with the king were at first pleasant, but after the king's rejection of the 'Four Bills' tendered him by parliament at the end of December 1647, he was more closely confined, and the position of the governor became difficult. Rumours spread of angry scenes;
Thomas Herbert complained that Hammond searched the king's cabinet for papers. In the king's secret correspondence in the summer of 1648, he wrote of Hammond's incivility. In May 1648 two of the gentlemen attending the king, Osborne and Dowcett, were accused of a plot to abet his escape, and were arrested. Osborne asserted that Hammond's second in command, Major Rolph, had plotted against the king's life, and that the governor was cognizant of it. He had begged to be relieved from his task. In November 1648 the breach between the army and the parliament involved Hammond. Cromwell, Ireton, and other representatives of the
Council of Officers wrote, arguing that his obedience was owed to the army rather than to the parliament, and that he should take their side in the struggle. On 21 November he received a letter from Fairfax, ordering him to come to
St. Albans, and informing him that Colonel Ewer had been sent to guard the king during his absence. This was followed by the appearance of Ewer himself, with instructions to secure the person of the king in
Carisbrooke Castle till it should be seen what answer the parliament would make to the army's remonstrance. Hammond felt bound to obey the commander-in-chief, and set out for St. Albans; but he announced his intention of opposing Ewer by force, if necessary, and left the king in charge of Major Rolph and two other officers, with injunctions to resist any attempt to remove Charles from the island. The House of Lords commanded Hammond not to leave his post, but he had already started, and when he tried to return he was detained and put under guard until the king had been seized and carried to
Hurst Castle. Hammond's custody of the king had lasted from 13 November 1647 to 29 November 1648, and parliament voted him a pension. ==Later life==
