Macartney was expected to lead an embassy to Japan after he completed his mission to China, but his hopes of being able to proceed to Japan were ended by the confirmation when he returned to Canton of news of the outbreak of war with France and consequently of the vulnerability of his ships to attack by French cruisers operating from Batavia. On 23 December, Macartney recorded in his journal: "I have given up my projected visit to Japan, which (though now less alluring in prospect) has always been with me a favourite adventure as a possible opening of a new mine for the exercise of our industry and the purchase of our manufactures".
