No sooner were the forts in possession of the allies than measures were taken to disable the guns and dismantle the works. The sappers only were employed in carrying out the mining operations under the direction of their officers. In this duty they worked with so much energy, that their exertions were scarcely checked by the fatigues to which they were necessarily subjected. Forts Prasto, Nottich, and Bomarsund all fell in turn—blown up by mines skilfully laid and fired. The magazines also were exploded, the shot and shell removed, and stores of timber, prepared for use in the contemplated fortifications, were burnt. The work of destruction extended even to the garrison chapel; it was sacked and then destroyed, and all the unfinished forts and buildings, rising from foundations which marked the extent of a stupendous engineering design, were torn up by mines and thrown down. The stone landing-pier was likewise demolished, and not a slab of granite which promised to be of service in future works was left unbroken. But a few weeks, and what a change! This proud maritime position—this formidable outport of the yet impregnable Cronstadt, studded with forts and bristling with ordnance, was one widespread area of ruin and desolation! Brigadier-General Jones and the officers of the corps were well pleased with the military bearing and exertions of the company, and commended the “cheerful and willing manner in which they performed the laborious duties” assigned to them. Besides the non-commissioned officers and men named above, there were others noted for their services. Privates John Williams,[138] John Veitch,[139] and Francis Enright, for their boldness, resolution, and zeal. Corporal George Luke,[140] for his ability and usefulness as a miner in the demolition of Bomarsund. Sergeant John Jones,[141] for his assistance as a draughtsman; and sergeant Richard P. Jones,[142] for his general diligence and intelligence, as well in the general operations as in the special one of diving. The ‘Penelope’ having run ashore on an unknown rock off Bomarsund, was compelled to throw fifteen of her guns overboard to float and save her. Several naval divers attached to the fleet were afterwards employed to bring them up; but as some submarine difficulties prevented as speedy an accomplishment of the undertaking as was desired, the co-operation of sergeant Richard Jones was found to be an acquisition, inasmuch as he recovered five 8-inch guns and one 10-inch. There was much sickness among the sappers during the brief campaign, and on one day no less than forty-seven men out of a company not a hundred strong, were on the sick-list with choleraic symptoms; but owing to the attention of the naval surgeons, only two died. Quitting the Baltic Sea in the ‘Cumberland,’ the company rejoined the corps at Woolwich on the 16th October, and before two months had intervened, was despatched in all haste to Turkey.
