The Spanish name calentura, by which the fever in the fleet is described, was probably used generically for various kinds of fever in the tropics. But of this fever in particular, we have some details not without diagnostic value. It was doubtless contracted at St Jago in the Cape de Verde islands; it broke out suddenly in mid ocean after some seven or eight days sailing before the wind, in a delightful climate, which points to the regular incubation of an infective virus, received by hundreds of men when they were last ashore; the mortality was enormous; the symptoms were those of a burning fever; and in some cases there were small spots or petechiae like those often seen in the plague. It was clearly a febrile form of pestilential infection, and, as few recovered, it must be considered to have had a death-rate such as typhus has rarely had, and such as yellow fever has commonly had. Nothing is said of the black vomit, the haemorrhages, and the saffron colour of skin and eyes, which are distinctive of yellow fever[1132]. On the other hand there is a remarkable after-effect mentioned in both the passages quoted, the loss of memory, impairment of wits, and appearance of foolishness, which made “the calenture” a bye-word in the fleet. I shall not venture to say what the infection was; but it seems tolerably certain that it was contracted by the English during their occupation of the capital town of St Jago. More recent visitors to the Cape de Verde islands have remarked upon their towns and villages as fever-traps, and have pointed to the source of the fever; it is not malaria, or the mere climatic influence, but a pestilential emanation from spots of soil long inhabited by mankind, both black and white, and so situated in cups of the hills as to retain and multiply the filth-ferment in them. According to all analogy, the emanations from such a soil would be felt most by strangers not inured to them, and most of all by men of another stock and from other latitudes[1133].
Sicknesses of Voyages, continued: Management of Scurvy.
The expedition to Virginia which returned in 1586 with Drake’s ships homeward bound from the Spanish Main, was the first sent out by Raleigh with the intention of settling, an earlier voyage in 1584 having been made to explore the country. It is in connexion with Raleigh’s second colony (and fourth expedition) in 1587 that we hear of disastrous sickness[1134]. Having left 118 people to inhabit the country, the two larger ships sailed for home on August 27 of the same year. On board the “fly-boat,” the provisions fell short, the water turned stinking, officers and men died, and the vessel was navigated with difficulty to the west coast of Ireland. When they reached Portsmouth, they found the admiral arrived there three weeks before them, but with an equally disastrous experience: “Ferdinando the master, with all his company were not only come home without any purchase, but also in such weakness by sickness of their chiefest men that they were scarce able to bring their ship into harbour, but were forced to let fall anchor without.”
The following year, 1588, was made memorable in the English annals of the sea by the defeat of the Spanish Armada. There was much sickness in both fleets. As regards the English ships, a writer who has had special access to original documents says[1135]:
“We little think, when we peruse the melancholy tale of disease, starvation and shame, so needlessly undergone by the heroic champions of England’s liberty against the invading might of Spain, from what obscure and insignificant causes the difficulties and hardships of the Island seamen may have chiefly arisen”—namely the peculation of officials, the mouldering rations, empty magazines, and the like. In the ships of the Spanish fleet the infection was like that of the plague itself; the main body of the expedition, fifty sail, reached Corunna, Santander and St Sebastian with such infection among the ten thousand men on board, that the inhabitants shut their houses against them.
Two of the heroes of that fight, Drake and Hawkins, met their death by sickness off the Spanish Main in 1595-6. The expedition, consisting of 2500 men in six Queen’s ships and twenty-one others, left Plymouth on August 28, 1595[1136]. Only the deaths of officers are mentioned in the narrative, but of these there seem to have been a good many, when the ships were in the Caribbean Sea. Hawkins died off Porto Rico on November 12. On December 7, Mr Yorke, captain of the ‘Hope,’ died of sickness, on January 15, captain Plat died of sickness, and then Sir Francis Drake began to keep his cabin and to complain of a scouring or flux: he died on January 28, off Porto Bello. On the 27th died captain Jonas of the ‘Delight,’ captain Egerton, and James Wood, chief surgeon of the fleet, out of the ‘Garland.’ On the 28th died Abraham Kendall out of the ‘Saker.’ Several of the ships were sunk so that their men might go to the Queen’s ships, which were short of hands. A muster on February 6 showed in the whole fleet “two thousand sick and whole,” or five hundred fewer than had sailed. There was some loss of life in encounters with the enemy, but much more from disease.
Of the filibustering cruises or expeditions to the East by the South American route, there remain to be mentioned two by Thomas Cavendish, and one at some length by Richard Hawkins, before we come to the establishment of regular English trade to the East Indies by the Portuguese route round the Cape of Good Hope. Cavendish’s first voyage[1137] by the Straits of Magellan was from Plymouth, 25 July, 1586, with three ships (240 tons in all) carrying 125 men.
Touching on the west coast of Africa, they went ashore and took lemons from the trees. Off the coast of Brazil in November and December two men died “of the disease called scorbuto, which is an infection of the blood and the liver.” Arrived at the Straits of Magellan they found twenty-three Spaniards living on shell-fish, “which were all that remained of four hundred which were left there [to found a colony] in these Straits of Magellan, three years before, all the rest being dead with famine.” They were only too glad to hasten from this place, Port Famine, “for the noysome stench and vile savour wherewith it was infected through the contagon of the Spaniards’ pined and dead carkeises.” In one of Cavendish’s own ships, on February 21, 1588, when among the East Indian islands, Captain Havers died of “a most severe and pestilent ague, which held him furiously some seven or eight days. Moreover presently after his death, myself [Pretty, the narrator] with divers others in the ship fell marvellously sick, and so continued in very great pain for the space of three weeks or a month, by reason of the extreme heat and intemperature of the climate.”
One might guess that these were cases of ship-fever (or calenture); but in Cavendish’s last voyage we meet with a strange sickness which will perhaps baffle all nosological conjecture. This voyage, like the first, was intended for the East Indies by way of the Straits of Magellan[1138]. The three tall ships and two barks, having sailed from Plymouth on August 26, 1591, never got through the Straits; they were still within their recesses in April, 1592, many men having “died with cursed famine and miserable cold,” and sick men having been put ashore into the woods in the snow. The narrative (by John Lane), then follows the fortunes of one of the ships, the ‘Desire.’ Landing at Port Desire, in Patagonia, they found scurvy-grass growing, which they ate with oil: “This herb did so purge the blood that it took away all kind of swellings, of which many [had] died, and restored us to perfect health of body, so that we were in as good case as when we came first out of England.” There also they took on board 14,000 penguins, which they had dried on the rocks, mostly without salt; and sailed northwards on December 22. With only 27 men surviving out of 76, they left the coast of Brazil at Cape Frio (near Rio de Janeiro), and then began their more singular experience of disease.
