Napoleon died at St. Helena on the 5th May, and his remains were deposited with quiet solemnity in an unpretending tomb, shadowed by a willow, in Slane’s valley. The company of sappers at the station took part in the funereal arrangements. The stone vault was built by privates John Warren and James Andrews. The body was lowered into its resting-place by two privates of the company, and other privates, appointed for the duty, refilled the grave, and secured all with plain Yorkshire slabs. Thus, without epitaph or memorial, were entombed the ashes of the most extraordinary man of modern times. As the necessity for retaining the company, now reduced, by deaths and the withdrawal of a detachment in 1819, to twenty-five of all ranks, no longer existed, it quitted the island and arrived at Woolwich on the 14th September. Private John Bennett was detained for three months after the removal of the company, and during that period he was employed with the Clerk of Works, in giving over the stores of the engineer department to the island storekeeper.[243] ----- Footnote 243: Was an excellent clerk, and became in time a quartermaster-sergeant. After his discharge from the corps in 1843, he filled, for about ten years, important offices under the Surveyor-General of Prisons, and died while steward of Dartmoor Prison, in February, 1853, from a cold caught in that bleak quarter. The season was a peculiarly bitter and stormy one, during which three soldiers of the line, on escort duty, in crossing Dartmoor Heath, perished in the snow. ----- The company in Upper Canada changed its head-quarters in June, from Kingston to Isle aux Noix, and afforded parties for service at Quebec and Fort George, both of which were recalled to Isle aux Noix in August. In November, 1822, the greater part of the company was removed to Quebec, and the remainder were retained for the works at Isle aux Noix. From July to November, a sergeant and nine men, chiefly carpenters and smiths, were employed by the Board of Longitude under Major Colby and Captain Kater, in the operations for determining the difference of longitude between the observatories at Paris and Greenwich; and visited ten of the principal trigonometrical stations in England. Besides attending to the laborious requirements of the camp, the party erected poles, and constructed stages or platforms wherever needed, on commanding sites and towers, for purposes of observation; and were also intrusted with the care of the philosophical instruments. In the professional operations of the season they took no part.[244] ----- Footnote 244: Captain Kater, in his account of the operations published in the ‘Philosophical Transactions,’ 1828, p. 153, notices, by mistake, this party as belonging to the royal artillery. There were, it is true, two gunners of the regiment present, but they were employed as servants to the officers. -----
