How much of the ultimate success of the Crusade of 1239 (the most successful since the First in territorial terms) is attributable to Theobald's intentions and how much was just fortuitous is debatable.

Theobald returns from Palestine late in 1240, before Richard of Cornwall arrives, because he had not wished to be present during any more debating over the leadership and direction of the enterprise.

Souvenirs that he brings back to Europe include the rose called "Provins" (Latin name rosa gallica 'officinalis', the Apothecary's Rose) from Damascus, transporting it "in his helmet"; a piece of the true cross; and perhaps the Chardonnay grape, which in modern times is an important component of champagne and many still white wines.

Richard fights no battles but manages to negotiate for the release of prisoners and the burials of Crusaders killed at a battle in Gaza in 1239.

He also refortifies Ascalon, which had been demolished by Saladin.
