While these events were in progress in the Taeping capital, some events that must be briefly referred to happened on a different scene. The Triads, aided by the mob, rose in Shanghai, overcame the Emperor's officers and garrison, and on 7th September 1853 obtained complete mastery of the native city. The foreign settlement was placed in a state of siege, the men-of-war covered the approaches to the factories, and a volunteer corps was carefully organised and constantly employed. Then an Imperial army re-appeared on the scene, and laid siege to Shanghai, but it was conducted with no skill, and the situation remained unchanged. After twelve months' delay the French Admiral, Laguerre, decided to help the Imperialists, and he began to bombard the walls in December 1854. He combined with them in an assault, and 400 French sailors and the Imperialists attacked the walls which had been breached. The assault ended disastrously, for the rebels defended the houses, and at last drove back the assailants with much loss. The pressure of famine compelled the besieged some months later to make a _sortie_, when the Imperialists recovered the town. A similar rising, with a similar result, occurred at Amoy. The insurgents caused a great loss of life and property, but in the end the authorities gained the upper hand. These events compelled the foreign consuls and their Governments to reconsider their policy, which had been one of sympathy towards the Taepings, and gradually the conviction became universal that it would be well for civilization and trade if a speedy end were put to the Taeping rebellion. But for our own quarrel and war with the central Government these views would have borne fruit in acts at an earlier date than they did.
