Milner Gibson wrote that "even though Lyons should come away, I think the dispute may after all be settled without war[452]." Cornewall Lewis thought the "last mail from America is decidedly threatening, not encouraging[453]." But on December 19, Adams was at last able to give Russell official assurance that Wilkes had acted without authorization.

Russell at once informed Lyons of this communication and that he had now told Adams the exact terms of his two instructions to Lyons of November 30.

He instructed Lyons to accept in place of an apology an explanation that Wilkes' action was unauthorized--a very important further British modification, but one which did not reach Lyons until after the conclusion of the affair at Washington[454].

Meanwhile a notable change had taken place in American public expressions.

It now regarded "the Wilkes affair unfavourably, and would much prefer it had not occurred at all[455]," a reaction without question almost wholly caused by the knowledge of the British demand and the unanimous support given it by the British public[456].
