The captains of the crusade were asked to answer allegations of receiving bribes totalling 18,000 gold francs. The leaders did not deny the allegations, but argued that because they had been forced to leave behind valuable horses the money was compensation. The treasurer, Foulmere, and five of the captains  were imprisoned and fined 14,600 gold francs. On 9 January 1384, the Exchequer recorded the receipt of £287 9s. 4d. of money captured during the Flemish expedition, paid by one Henry Bowet on Foulmere's behalf, and the further receipt of £770 16s. 8d. for 5,000 francs "illicitly received" overseas.
