He sailed from Newcastle to Leith, and got home to Edinburgh. Here he dined with Sir James Stewart, and was extremely cheerful and hearty, but said, ‘there was never a schoolboy more desirous to have the play than I am to have leave of this world.’ He made his will on 17 August, and died on 19 August 1646. In the beginning of 1645 he was appointed to assist the commissioners of the parliaments of England and Scotland in conducting the treaty between them and the king at Uxbridge. On the breaking off of the treaty he returned to London. In the spring of 1646, when the king had thrown himself into the hands of the Scottish army, he sent for Mr. Henderson, who was considered the most competent person to deal with his majesty in his then circumstances. He arrived at Newcastle about the middle of May, and received a welcome reception from the king, but soon perceived that Charles was as unwilling as ever to consent to the establishment of presbyterianism. It was agreed that the scruples which the king entertained should be discussed in a series of papers between his majesty and Mr. Henderson. These continued from 29 May to 15 July. They are eight in number, five by the king, who was assisted by Sir Robert Murray, and three by his reverend opponent. Mr. Henderson's health being much impaired, he was obliged to remove by sea to Edinburgh, where he died, 19 August 1646, in the 63d year of his age. His body was interred in the Greyfriars churchyard, where a monument was erected by his nephew to his memory.
