The Chinese position was unusually strong, and had been selected with considerable judgment. An island named after the hyacinth lies in midstream two miles from the entrance to the Fatshan Channel, which joins the main course of the Sikiang a few miles above the town of that name. The island is flat and presents no special advantages for defense, but it enabled the Chinese to draw up a line of junks across the two channels of the river, and to place on it a battery of six guns, thus connecting their two squadrons. The seventy-two junks were drawn up with their sterns facing down stream, and their largest gun bearing on any assailant proceeding up it. On the left bank of the river an elevated and precipitous hill had been occupied in force and crowned with a battery of nineteen guns, and other batteries had been erected at different points along the river. There seems no reason to question the accuracy of the estimate that more than 300 pieces of artillery and 10,000 men were holding this position, which had been admirably chosen and carefully strengthened. The force which Sir Michael Seymour had available to attack this formidable position slightly exceeded 2,000 men, conveyed to the attack in six gunboats and a large flotilla of boats. The English advance was soon known to the Chinese, who began firing from their junks and batteries as soon as they came within range. Three hundred marines were landed to attack the battery on the hill, which was found not to be so strong as it appeared; for on the most precipitous side the Chinese, believing it to be unscalable, had placed no guns, and those in position could not be moved to bear on the assailants in that quarter. The marines gained the top with scarcely any loss, and as they charged over the side the Chinese retired with little loss, owing to the ill-directed fire of the marines.
