The exposure of men, whose systems were impregnated with the seeds of disease imbibed in this unhealthy locality, to the risks of unrestricted liberty on shore, in the atmosphere of Sierra Leone, during the rainy season; one consequence of which freedom being their “inordinate indulgence in ardent spirits of the worst description.”
And subsequently, at Boa Vista, the confinement of the crew, the sick as well as the uninfected, in a place still more crowded, filthy, and unventilated than their quarters on board, instead of their dispersion in a pure atmosphere.
Some conception may be formed of the unfavourable circumstances under which the crew were placed at the Fort, from the account which, on personal inspection, Dr King gives of its sanitary condition, who states that from the absence of all means of cleansing, from the actual accumulation of filth, and from the impossibility under any circumstances of obtaining a free circulation of pure air, owing to the plan of the building, the atmosphere which the sick, the convalescent, and the healthy were compelled to breathe, day and night, must have been polluted and deleterious in the extreme; and that into a space incapable of affording sufficient accommodation for 50 men, upwards of 100, including the sick, were huddled together under a most oppressive heat, the thermometer ranging from 81° to 86°. This description is confirmed by the testimony of Dr Almeida, who states that having been requested by the Governor-General to go to the Fort and see the sick, “he found them so extremely crowded that he could hardly pass between them.”
The influence of such conditions in conducing to the virulence and spread of the disease has been already exemplified in what has been stated under the head “Localizing Causes;” but it must be added, that the crew had here also access to ardent spirits, in which both the sick and the uninfected indulged to still greater excess even than at Sierra Leone.
“It is with great regret,” says Sir William Burnett, “I have now to state on the best information, that while in this situation means were found to supply the sick as well as others with enormous quantities of ardent spirits, which were drunk with avidity and produced the most deleterious effects; indeed, I have reason to believe that some were absolutely killed by it as if by poison. Had there not been a fever already in existence, the intense heat (86° of Fahrenheit), the nature of the soil, and this dreadful intoxication together, would have been fully sufficient to have produced it, and one of the worst kind too, in which irritability of the stomach and dark-coloured vomiting would have been conspicuous symptoms.”
The actual result, as stated by Dr McWilliam, was that the accession to the sick-list and the mortality became much greater at this time than they had been at any previous period, and that from an endemic remittent of the African coast, the disease became exalted into a concentrated remittent or Yellow Fever.
Indubitable evidence further shows that, in addition to all these causes of disease, the crew when on board were constantly inhaling a poison generated in the ship itself. On a superficial examination the ship may have appeared clean, and Sir William Pym positively asserts that she was so; but there is conclusive evidence that this appearance was fallacious.
From the records of the Medical Department of the Navy have been extracted the following decisive statement with reference to this point, by Captain Simpson, late of the “Rolla:”—
“In June, 1845, being then in command of the ‘Rolla,’ I went on board the ‘Eclair’ off Shebar River. Commander Estcourt reported to me that he had sent a boat up the Sherborough River, and that the crew, during night, were exposed to heavy rain and much lightning, and were sick: some deaths had occurred on board. In the early part of July I went to Sierra Leone for supplies; the ‘Eclair’ was there; the vessel was anchored close to the shore; and I advised her Commander to move her further out, which he did. There seemed much excitement amongst the crew; some liberty had been given them, and drunkenness and sickness were the consequence. Wood was received on board for fuel in lieu of coals. This wood was green, as I understood at Sierra Leone, and very unhealthy to burn.”
This fact is substantiated by the log of the “Eclair,” which shows that from July 16th to the 19th inclusive, the crew were employed at Sierra Leone in wooding.
