The new Swedish coalition destroyed French hopes for a quick negotiated settlement. Koryciński complained to de Lumbres that he had been deceived, since Charles X had shown himself little inclined to peace: the more Poland conceded, the more hardline Sweden's position became. He dwelt on the efforts he had made to persuade the Poles to settle and stressed the reproaches he had suffered for delaying the Muscovite talks: ‘This gives good sport to his enemies and to those who wish to criticise his conduct. He reproaches himself for the credulity which he has shown towards the Swedish proposals.’ Despite de Lumbres's attempts to console him with news of les civilités which Mazarin was offering him, the chancellor continued to show much resentment. French hopes of mediating peace in the short term were dead: Charles merely temporised, demanding that John Casimir call a diet to approve the powers of the Polish commissioners. John Casimir told de Lumbres that if no reply were forthcoming by the end of January, he would leave Danzig to put Wilno into effect. When the reply finally came in March, after the meeting of Charles and Frederick William at Preussisch-Holland, it offered new talks, but although Charles hinted that he might be prepared to evacuate Poland for the right price, there was no indication of a major change of heart.
