On August 17 Buckingham went down to Portsmouth to consult the King concerning certain proposals to bring about peace between England and France which he had just received from the Venetian Ambassador, Contarini. Both he and Charles had now begun to realise their folly in engaging in a war with France while they had so many troubles at home, and while their hapless allies in Germany and Denmark, to whom they were powerless to render any effective aid, were justly imputing to them their misfortunes. They appear to have thought less of fighting, for they could not disguise from themselves that the difficulty of relieving La Rochelle must by this time be almost insuperable, than of obtaining for the Rochellois, by a great display of force, tolerable terms. Buckingham, however, was never again to see the shores of France, as on the morning of August 23 he was assassinated by Felton.

The duke’s death did not alter the situation, but it, of course, delayed the departure of the fleet, and it was not until more than a fortnight later that it at last sailed, under the command of the Earl of Lindsey, who had succeeded to Buckingham’s office of Lord High Admiral. It was an infinitely more powerful fleet than that which Denbigh had commanded, and consisted of some 120 vessels of various sizes, including fire-ships and vessels loaded with bombs to blow up the stockades.

In the afternoon of the 28th the sentinel in the belfry of Saint-Martin-de-Ré signalled to Bassompierre the approach of the English, and towards night the advance-guard cast anchor in a bay off the Île de Loix.

On the following morning the English ships got under way and approached the canal, but the wind changed and they returned to their stations. The Cardinal, who had come to Chef de Baie, offered to take Bassompierre back to the marshal’s quarters in his coach. On the way they both had a narrow escape, a cannon-shot from the town ploughing up the ground close to the coach and filling it with earth.

In the afternoon Louis XIII sent to inform Bassompierre that he proposed to do him the honour of taking up his quarters with him at Laleu, adding that he was to make what arrangements for his reception he thought fit and was to put himself to as little inconvenience as possible. His Majesty arrived, accompanied by his whole entourage, and more than twelve hundred gentlemen, to say nothing of his Household troops: Musketeers, Light Horse, Gensdarmes and Gardes du Corps, for all of whom Bassompierre had to find accommodation. However, he rose to the occasion and “received and entertained the company in such fashion that everyone marvelled.” The King remained five weeks at Laleu, and as he was graciously pleased to regard himself as the guest of the marshal, the latter had, of course, to defray the expenses of his stay, which amounted to 800 crowns a day.

Another squadron of the English fleet arrived that evening, and two more, including sixteen powerful ships-of-war, on the following day. During the afternoon some of the King’s ships stood in towards Chef de Baie and exchanged shots with Bassompierre’s batteries, after which they all came to anchor in the Straits of Antioche.

On October 1 the remainder of the English fleet came in, but contrary winds prevented any forward movement during that and the following day. But towards morning on the 3rd the wind changed, and Bassompierre judged, from the boats passing continually to and fro between the vessels, that an attack was preparing. He was right, for, so soon as morning broke, the English ships got under way and stood in towards the canal.

The marshal at once ordered the drums to beat to quarters and sent to warn the King and the Cardinal. They both hastened to Chef de Baie, where Louis announced his intention of remaining, while the Cardinal went to take up his station on the mole.

Favoured by wind and tide, the English fleet approached in three divisions. It was an imposing spectacle. The French fleet, under the orders of Valençay, filled the canal. The mole, which since the departure of Denbigh’s expedition had been completed and strengthened by the erection of a double row of gigantic chevaux de frise, the two floating stockades, the forts, the cliffs, the banks of the canal, bristled with guns and soldiers. Thousands of volunteers from all parts of France had flocked to La Rochelle to take part in the long-expected combat and filled the ships and the boats. Standing on the mole, in the centre of the great scene, the Cardinal calmly contemplated the coming of the enemy; while on the ramparts of the beleaguered town the famished citizens awaited in silence the issue of the battle which was to decide their fate.

Alas for the unhappy Rochellois! The sufferings which they had endured with such heroic fortitude were all in vain. The officers and crews of Lindsey’s fleet were no more ready to follow him into danger than those of Denbigh’s had been to follow their commander in the spring. The masters of the armed merchantmen, which formed the advance-guard, complained that they were being deliberately sacrificed to save the King’s ships, which had been ordered to follow in support. The King’s ships drew too much water to come to close quarters, and the admiral could only order them to stand in as far as possible without running aground. They took good care that there should be no possibility of that.
