The deputy governor, whom Warwick had left at Calais, was one Vaucler, a Gascon, who, seeing the earl return in this miserable condition, refused him admittance; and would not so much as permit the duchess of Clarence to land, though, a few days before, she had been delivered on shipboard of a son, and was at that time extremely disordered by sickness.

With difficulty he would allow a few flagons of wine to be carried to the ship for the use of the ladies: but as he was a man of sagacity, and well acquainted with the revolutions to which England was subject, he secretly apologized to Warwick for this appearance of infidelity, and represented it as proceeding entirely from zeal for his service.

He said that the fortress was ill supplied with provisions; that he could not depend on the attachment of the garrison; that the inhabitants, who lived by the English commerce, would certainly declare for the established government; that the place was at present unable to resist the power of England on the one hand, and that of the duke of Burgundy on the other; and that, by seeming to declare for Edward, he would acquire the confidence of that prince, and still keep it in his power, when it should become safe and prudent, to restore Calais to its ancient master.[*] It is uncertain whether Warwick was satisfied with this apology, or suspected a double infidelity in Vaucler; but he feigned to be entirely convinced by him; and having seized some Flemish vessels which he found lying off Calais, he immediately made sail towards France.
The king of France, uneasy at the close conjunction between Edward and the duke of Burgundy, received with the greatest demonstrations of regard the unfortunate Warwick,[**] with whom he had formerly maintained a secret correspondence, and whom he hoped still to make his instrument in overturning the government of England, and reestablishing the house of Lancaster.
