The Chinese were convinced that it would be impossible for the Europeans to capture their city, held as it was by a greatly superior force of regular Chinese troops, and protected by a very large number of guns.

The bombardment was to be greatly deplored, for the enormous injury inflicted upon Tientsin could not but cripple the trade there for many years, and probably divert it to other channels. Still, the necessity could not be denied, grievous though its effects might be.

The Russians had already started from their camp, which was on the opposite side of the river, in the foreign settlements, and marched against the Peiyang arsenal, which is on the same side, about a mile and a half up. It was defended by several thousand Chinese, with six nine–pounder Krupps. The attack had to be made across an open plain, and this was swept by an incessant rifle fire, while the Chinese artillery made excellent practice. The casualties mounted up quickly, and before long a halt was called, and messengers were sent to Tientsin to ask for reinforcements.

When the messengers arrived, the bugle sounded and the troops hastily assembled. The whole of the Naval Brigade, under Captain Bourke of the Orlando, was called out, including a battalion of marines under Major Johnston, and with them went a twelve–pounder gun from the Terrible. The American Marine Artillery also went out, together with a detachment of Tientsin volunteers. When they got to the scene of action, they found the Russians shelling the arsenal under cover of the railway embankment.

No movement was made till eleven oʼclock, when a Russian shell exploded in the principal Chinese magazine, which contained no less than eighty tons of powder. The explosion was terrific, and for some minutes a great cloud of smoke hung over the arsenal. The shock was so severe that soldiers who were standing up at the time were thrown off their feet by it, and the sound was heard distinctly at Taku, thirty miles away. The British had increased their fire, and shortly afterwards a Terrible twelve–pounder put a shell into the smaller magazine, which also blew up. Each explosion was hailed by the troops with tremendous cheers, which a few minutes later were redoubled when the Chinese were seen leaving the fort. The British and Americans, who were nearer than the Russians, at once advanced at the double. Some Chinese, composed of sterner stuff than their comrades, still kept up their fire, causing some casualties, but they also retreated in good time to secure their own safety.

When the storming party was close to the arsenal, what seemed to be a tremendous musketry fire broke out from the building, and, supposing that there was still a very large force there, the troops halted. Presently, however, the fire ceased altogether, and they again advanced. When they entered the place they discovered that the fire that had checked them was not musketry, but long strings of crackers which the Chinese had prepared to check any storming party, and thus secure their own retreat. Angry as the troops were at being deceived, they laughed heartily at the trick that had been played upon them.

After the arsenal was occupied, a large mixed force of Chinese regulars and Boxers came out from Tientsin city, at the back of the railway–station, and placed themselves between the arsenal and the river, on the very ground the British and Americans had occupied, and their first act was to massacre all the wounded who had been left there. One poor fellow alone was saved, for although he had been very seriously wounded in both legs he managed to run, and the British–Chinese regiment coming up at the moment, he was able to reach the arsenal in safety.

The murder of the wounded exasperated the troops to the last degree, and palliated, if it did not excuse, the general refusal of quarter to the Chinese during the campaign. In Tientsin a document was found showing that rewards had been paid to several Chinese who had brought in the heads of British and American soldiers.

The capture of the arsenal enabled all the women and children to be sent away within the next few days, which was a fortunate occurrence, for large reinforcements of Chinese troops entered the city the day after, and the settlements were again exposed to a vigorous fire.
