God's Fury, England's Fire_ A New History of the English Civil Wars - Michael J. Braddick [336]
Moves towards the trial of the King went in tandem with attempts at negotiation, which probably reflected the desire to avoid this third war as much as anything else. Those who promoted the purge had been united by a desire to prevent the progress of the Treaty of Newport, probably in the face of this menacing international situation, rather than to execute the King and abolish monarchy. In the face of the growing naval threat, the allegiance of the navy was crucial. The experience of 1648 had been that the navy was not four square behind the most radical army programmes, and the arrival of the Earl of Warwick back in London seems also to have had a restraining influence on the course of political action: it is plausible that he wanted prominent royalists tried, not the King, and it is unlikely that he supported regicide at this point. Those opposing the treaty at Newport feared that this treaty would give too much ground to the King, and that delay was simply offering him the opportunity to re-gather his strength. On the other hand, killing the King was not a particularly attractive alternative. With peace on the cards in Ireland, and Scotland divided but hardly supportive of the army programme, it could plausibly be said that the best way to start a third war would be for the English to execute Charles, who was after all the King of Ireland and Scotland too. With the legitimate claimant beyond the seas and out of reach, there was more than enough reason to think that regicide would precipitate further armed conflict. And this line of thinking was vindicated after the fact too – following the King’s execution the army was indeed forced into battle again, in both Scotland and Ireland, against armed supporters of the Prince of Wales.38
This is the context for another attempt to engage the King, the ‘Denbigh mission’ of late December. The details of the offer are unclear, but seem to have been that the King should accept the alienation of the bishops” lands (and hence, by implication, the perpetual abolition of episcopacy), abandon his Negative Voice and renounce any role for the Scots in the settlement of English affairs. Denbigh was also keen in these months to secure a disavowal of Ormond from the King. Such a deal would have allowed Charles to keep his life and throne.39 Charles met the approach with a rebuff – Denbigh was not admitted to the presence. Another approach made by the Earl of Richmond, on 11 January, is even more obscure in its details, but it too bears testimony to the continuing desire to negotiate a settlement. Even during the trial there were apparently attempts to get the King to abdicate in favour of the Duke of Gloucester.40
Purge, and even trial, did not lead directly to regicide. Throughout the period from the purge on 6 and 7 December 1648 until the eve of the King’s execution there were hesitations and delays. The best explanation
