The Emperor had no intention of carrying out any such agreement--on the contrary he issued a mandate for the extermination of the British. As a result of this flagrant breach of faith, an expedition was sent to the Island of Amoy, and appeared before the city of Amoy on August 25th. Two hours' bombardment sufficed to demoralise the garrison, despite their 500 pieces of cannon, and a force of troops was landed. Chusan was retaken, the military depot of Chinghai stormed, and the fortified and important city of Ningpo captured. A determined effort was made on March 10th, 1842, to retake it, but despite the surprise the enemy was beaten off. Later the British left Ningpo and again proceeded up-river, attacking Tsekee on March 15th, capturing the heights of Segon and forcing the Chankee pass ere returning to Ningpo on March 17th. In May Ningpo was evacuated, and the fortified city of Chapoo at the mouth of the Shanghai River attacked and a landing effected. In June Woosung and Poonshau, and the city of Shangee, were captured, and with the aid of the 98th Regiment under Lieutenant-Colonel Campbell (afterwards Lord Clyde), which now reinforced the expedition, the city of Chin-Kiang was attacked, and after a severe struggle taken on July 21st, 1842. Lieutenant-Colonel Sir Hugh (afterwards Viscount) Gough, whose decoration from Dr. Payne's collection is used to illustrate the medal awarded for this campaign, led his army to the ancient capital Nankin, which was reached on August 9th, 1842. The demonstration sufficed to bring the enemy to reason, and a treaty of peace was signed, the indemnity paid, the ports of Amoy, Ningpo, Foo-choo-foo, and Shanghai opened to British commerce, and Hong Kong ceded to us. The army of about 3,000 men was composed of the 18th Royal Irish, 26th Cameronians (which lost nearly 600 men out of 900, by disease, before Canton fell), 49th, 55th (which particularly distinguished itself at the assault on the city of Chin-Kiang), 98th, 37th Madras Infantry, Royal and Indian Artillery, and a Naval Brigade, including marines, also took a prominent part.
