This compact, into which the King of Naples was also to enter, guaranteed their mutual possessions by the whole power of both kingdoms.

This in itself was a weighty undertaking; but the secret clause further stipulated that Spain should declare war against England on the 1st of May, 1762, if peace with France had not then been made.

Negotiations of this character could not be kept wholly secret, and Pitt learned enough to convince him that Spain was becoming hostile in intention.

With his usual haughty resolve, he determined to forestall her by declaring war; but the influence against him in the councils of the new king was too strong.

Failing to carry the ministry with him, he resigned on the 5th of October, 1761.
His prevision was quickly justified; Spain had been eager in professing good-will until the treasure-ships from America should arrive laden with the specie so needed for carrying on war.
