Grenville of course sent no answer to the last missive of Maret; but to Lebrun he replied, on 18th January, that his explanations were wholly unsatisfactory, as they maintained the right of the Executive Council to annul treaties at will. Until satisfaction were granted for the aggressions on His Majesty's ally, he would continue to take all measures needful for their common safety. The terms of this reply were doubtless due to the last news received from Paris. On 12th January the arch-intriguer, Brissot, had fired off at the Convention a warlike harangue in which he depicted the British Ministry as helpless in the midst of a discontented populace and without a friend in the world. France could therefore easily arouse Ireland and Scotland to revolt, besides carrying liberty to India.[179] On the following day the Convention ordered the equipment of 30 sail-of-the-line and 20 frigates, and the construction of 25 sail-of-the-line and 20 frigates.
On his side Chauvelin saw the rupture to be imminent. In forwarding Grenville's despatch to Lebrun on the 19th he described his situation in London as intolerable, and added that no alternative but war was left. His assistant, Reinhard, ended a letter of that day to Miles with the words "_M. Chauvelin leaves_." That resolve must have been strengthened by Grenville's haughty note of the 20th, stating that no special means could be taken to protect his couriers and that he must rank "among the general mass of foreigners resident in England." On the same day Grenville informed Sir James Murray, who had gone on a special mission to the Prussian headquarters, that war was likely to break out, as France "insists on terms entirely inconsistent with the Government of this country and His Majesty's dignity and honour." His Majesty is strenuously making preparations and hopes to concert plans with Prussia and Austria.[180]
Such was the state of affairs on 21st January, when Louis XVI laid his head on the block in the Place de la Révolution. The news of this tragedy reached London late in the afternoon of the 23rd; and the horror which it aroused led to a demand at the Haymarket that the farce should be put off. On the advice of the Cabinet George III now intervened. At a Court held on the morrow at the Queen's House (on the site of Buckingham Palace) an order was issued that Chauvelin, as the envoy deputed by Louis XVI, should leave the country on or before 1st February. But on or before 25th January, that is, before the news of this mandate can have reached Paris, Lebrun had decided to recall the French mission from London. On 25th January he wrote to Monsieur Greenville [_sic_] stating that, as his plenipotentiary, Chauvelin, had orders to return to Paris, Maret would proceed to London to look after the papers at the French Embassy. This statement merits attention; for it shows that Chauvelin's departure was hastened only a day or two by the King's command;[181] and further it refutes the oft-repeated assertion that Maret came charged with offers of peace to which Pitt and Grenville paid no heed.
