Nearly five days were employed in collecting the tools and stores, cutting roads, effecting preliminary reconnaissances, preparing an hospital, and in providing domiciles for the temporary accommodation of the company, by making huts of the branches of fir trees; while a strong party, about 400 yards from the hill, worked with unflagging industry in making fascines and filling sand-bags, which, when finished, were carried by the seamen and marines to the depôt near the site of the intended battery. Meanwhile two or three attempts had been made by some officers of the corps, attended by a few intrepid sappers, to trace the battery; but the enemy opened so heavy a fire upon the parties, that a suspension of their exertions necessarily followed. Determination and tact, however, got over the difficulty. No trace was used, but a simple alignment struck, from which, on the 13th August, under shade of the evening, sergeant John Jones and twenty-four rank and file, began to construct the battery, under the orders of Captain Ord. Without the chance of digging a shovel-full of earth to give solidity and strength to the cover, the battery was built on the bare rock entirely of fascines and sand-bags. The sappers reared it unassisted, except that the royal marines carried the material from the engineer’s park to the hill. Sergeant John Jones had the honour of laying the first sand-bag. In ten hours, the detachment, unrelieved, nearly completed the battery, which would soon have opened upon Fort Tzee; but the French having forestalled the arrangement by obtaining the surrender of its commandant, the battery was free for other employment, and its direction was consequently changed against Fort Nottich. Speedily the epaulement which flanked the battery was prolonged, the platforms promptly laid, and three 32-pounders having been placed in position, the embrasures were unmasked by some daring sappers, and the firing, which lasted about nine hours, ended at the fall of the day in the capture of the garrison. It was surrendered to Captain Ord, R.E., who had with him to receive the formal capitulation, a force of 100 of the royal marines and five rank and file of the sappers.
