The day before the English commander perceived that he was in face of a strong force Mr. Parkes and some other officers and civilians had been sent ahead with an escort of Sikh cavalry to arrange the final preliminaries with the imperial commissioners at Tungchow, both as to where the camp was to be pitched and also as to the interview between the respective plenipotentiaries of the opposing powers. This party proceeded to Tungchow without encountering any opposition or perceiving any exceptional military precautions. Troops were indeed observed at several points, and officers in command of pickets demanded the nature of their business and where they were going, but the reply "To the Commissioners" at once satisfied all inquiries and opened every barrier. The one incident that happened was of happy augury for a satisfactory issue if the result went to prove the fallaciousness of human expectations. A change had in the meanwhile come over the minds of the imperial commissioners, whether in accordance with the working of a deep and long-arranged policy, or from the confidence created by the sight of the numerous warriors drawn from the cradle of the Manchu race for the defense of the capital and dynasty, can never be ascertained with any degree of certainty, Their tone suddenly assumed greater boldness and arrogance. To some of the Englishmen it appeared "almost offensive," and it was only after five hours' discussion between Mr. Parkes and the commissioners at Tungchow that some sign was given of a more yielding disposition. The final arrangements were hastily concluded in the evening of September 17 for the arrival of the troops at the proposed camping ground on the morrow, and for the interview that was to follow as soon after as possible. While Mr. Parkes and some of his companions were to ride forward in the morning to apprise Sir Hope Grant of what had been agreed upon, and to point out the site for his camp, the others were to remain in Tungchow with the greater part of the Sikh escort.
