But, at the same time, he felt what renown and importance a devotion like that of the six burghers of Calais could not fail to confer upon such men, and not only did he trouble himself to get them back to their own hearths, but on the 8th of October, 1347, two months after the surrender of Calais, he gave Eustace de St.Pierre a considerable pension "on account of the good services he was to render in the town by maintaining good order there," and he re-instated him, him and his heirs, in possession of the properties that had belonged to him.

Eustace, more concerned for the interests of his own town than for those of France, and being more of a Calaisian burgher than a national patriot, showed no hesitation, for all that appears, in accepting this new fashion of serving his native city, for which he had shown himself so ready to die.

He lived four years as a subject of the King of England.

At his death, which happened in 1351, his heirs declared themselves faithful subjects of the King of France, and Edward confiscated away from them the possessions he had restored to their predecessor.

Eustace de St.Pierre's cousin and comrade in devotion to their native town, John d'Aire, would not enter Calais again; his property was confiscated, and his house, the finest, it is said, in the town, was given by King Edward to Queen Philippa, who showed no more hesitation in accepting it than Eustace in serving his new king.
Long-lived delicacy of sentiment and conduct was rarer in those rough and rude times than heroic bursts of courage and devotion.
Philip of Valois tried to afford some consolation and supply some remedy for the misfortune of the Calaisians banished from their town.
