When the French had captured Fort Tzee the Brigadier-General gave an order for sergeant John Jones to make a plan of it. He had a note to the officer commanding the garrison requesting the service to be permitted. Taking with him privates John S. Rowley and George Peters to assist, he started on the morning of the 15th, but contrary to expectation found the French had abandoned the work and taken shelter in an advanced trench. Presenting the request to the French Commandant, the sergeant awaited authority to proceed. The fort was on fire, having been shelled by the Russians the previous evening. The Commandant and several French officers advised Jones not to venture into the place, but with soldier-like firmness he persevered in urging the performance of the duty; and permission being granted, he and his assistants went on. Going through one of the embrasures, which was on fire, and the gun-carriage burning, they pushed into the tower. Loose powder, broken cartridges, and five shells were lying about; the flames had nearly spread to the principal magazine, the remainder of the building had more or less fire in every casemate, and the smoke in thick columns was streaming from the crackling apertures. With difficulty they gained the first floor, and then, finding the stairs, penetrated to the roof, not without being almost suffocated, and losing, for a time, private Rowley in the smoke. From floor to floor and embrasure to embrasure they moved, in hopes of stealing the barest chance of taking even a few measurements, but their efforts were unavailing; and so, compelled to quit the tower, they had scarcely reached their own camp, about 1,200 yards away, when the flames having communicated with the magazine, it exploded, and the fort blew up. Without attempting to chronicle the different incidents of the campaign, in which the fleet and the French troops so gallantly participated, it will be sufficient to note that Bomarsund, the principal fort of the Aland Islands, capitulated without material opposition, and the Russians were marched out prisoners of war. The sappers and miners and royal marines formed in line, faced by a force of the French infantry; and through their divided ranks, the Russians moved pensively away to the point arranged for their departure.
