the third time. He presented a draft of the famous Solemn League and Covenant, which was received with great enthusiasm. Unlike the National Covenant of 1638, which applied to Scotland only, this document was common to the two kingdoms. Henderson, Baillie, Rutherford and others were sent up to London to represent Scotland in the Assembly at Westminster. The Solemn League and Covenant, which pledged both countries to the extirpation of prelacy, leaving further decision as to church government to be decided by the example of the best reformed churches, after undergoing some slight alterations passed both parliaments, the Parliament of Scotland and the Parliament of England, and thus became law for the two kingdoms. By means of it Henderson has had considerable influence on the history of Great Britain. As Scottish commissioner to the Westminster Assembly he was in England from August 1643 till August 1646 and his principal work was the drafting of the Directory for Public Worship. Last days Early in 1645 Henderson was sent to the Treaty of Uxbridge to aid the commissioners of the two parliaments in negotiating with the king but nothing came of the conference. In 1646 the king joined the Scottish Army; and, after retiring with them to Newcastle-upon-Tyne, he sent for Henderson, and discussed with him the two systems of church government in a number of papers. Meanwhile, Henderson was failing in health. He sailed to Scotland, and eight days after his arrival died, on 19 August 1646. He was buried in Greyfriars Kirkyard, Edinburgh; the grave lies in the south-west section near the Adam mausoleum. His death was an occasion of national mourning in Scotland. On 7 August Baillie had written that he had heard that Henderson was dying of heartbreak. A document was published in London purporting to be a declaration of Mr Alexander Henderson made upon his death-bed and, although this paper was disowned, denounced and shown to be false in the General Assembly of August 1648, the document was used by Clarendon as giving the impression that Henderson had recanted. Its foundation was probably certain expressions lamenting Scottish interference in English affairs. The failure of this last enterprise was fatal to Henderson's already broken health. In June 1645 he had suffered from gravel, and tried the Epsom waters; he now showed symptoms of decline. Baillie, on 7 August, wrote that he heard he was ‘dying most of heartbreak.’
