Lindsey was not far wrong on this occasion, for the withdrawal of the French ships from the narrow seas on the approach of the English fleet was due to the sagacious plan of Richelieu. He appears to have been well aware of the pretext and design of Charles, and endeavoured to outwit him. At war with Spain, he desired to avert an open rupture with England. At the same time, it was not fitting that he should break the tradition of France, or check the maritime ambitions which aimed at rivalling England on the seas, by lowering the French flag to the English Admiral. While the Earl was still at the Isle of Wight, Richelieu ordered the French Admiral to retire with three of his smallest vessels round Cape Finisterre to Belle Isle, off the coast of Brittany and well out of the Channel, and to put the rest of the French squadron under the command of the Dutch Admiral. The French ships left in the narrow seas were to carry no flags at all, and therefore could not strike them; and if the combined fleet met the English, the Admiral of the States would, in his accustomed manner, strike, without the dignity of France being compromised or Charles being given the rebuff for which he was seeking.[487] When on the following day Richelieu learned that the Spanish transports for the relief of Dunkirk had entered that port, he ordered the combined fleet to withdraw altogether from the Channel, as their further presence there was useless and might give occasion for a conflict.[488] Thus it was that Lindsey could not find them. While Richelieu’s strategy succeeded, the course adopted was somewhat pusillanimous and not calculated to add to the laurels of France. He therefore took advantage of an incident to raise the question of the flag diplomatically with England, in the hope of having the respective rights of the two nations settled, and no doubt for other reasons. He complained to Charles that the Earl of Lindsey--who denied the story--told a Dutch captain of whom he inquired the whereabouts of the French fleet, that he was “going to make them lower their colours”;[489] he inquired as to the intentions of the king, and he proposed that in future the French should salute the English on the coast of England, and, reciprocally, that the English should salute the French on the coast of France; while if the fleets were in the middle of the sea they should either pass one another without saluting, or the weaker fleet should first salute the stronger. If Charles did not like these proposals, he was invited to suggest others.[490] It appears indeed that instructions of a similar tenour had been actually given to the French Admiral, except that they might strike to the English when out of sight of the French coast.[491]
