Observations on the Diseases of Seamen

The monthly returns of the surgeons were very full and complete; but as it would be tedious to insert at length those of every particular ship, and as the number of ships fluctuated in different months, I shall do no more hereafter than set down the general results from calculation, so as to shew the proportional prevalence of disease and mortality in each month.

Table, shewing the proportional Sickness and Mortality in March

Transcriber’s Keys:

A Proportion of those taken ill in the Course of this Month.

B Proportion of those who died, in relation to the Numbers of the Sick.

The first column is formed by dividing the whole number on board by the number taken ill. The second column is formed by first adding the number ill on board on the first of the month to the number taken ill during the month, subtracting from this sum the number sent to the hospital, and dividing the remainder by the number of deaths.

The number on the sick list of twenty-eight ships of the line, and two frigates, on the first of this month, was eight hundred and forty-five; the number put on the lists in the course of the month was one thousand eight hundred and eighty-four; and the number sent to the hospital in the same time was three hundred and seventy-three; and there died on board thirty-one.

The total mortality this month, in relation to the whole number of men on board, was one in six hundred and seven.

It almost always happens, that ships of war are more or less short of complement, and allowance is made for this in all the calculations; for having had an opportunity of inspecting the weekly accounts delivered to the Admiral, it was always in my power to be informed how many there were short of the legal complement of men in each ship.

It appears, from comparing the Tables of this month with those of the preceding, that there had been a great increase of fevers and fluxes, particularly of the latter. The fevers prevailed chiefly in the ships lately from England, especially the Fame and Conqueror. In the Duke there were a great number ill of fevers; but this ship not having arrived from England till after the first of the month, is not included in the calculation. The fluxes were most prevalent in the ships we found on the station, particularly the Canada, Resolution, and Nymph frigate. The scurvy had increased very little, but prevailed most in the ships we found here. The only ships of the new squadron that had this disease to a considerable degree, were the Conqueror and Nonsuch. The former had indeed a good many ill of it; but the return having been made in an imperfect manner, this ship is not included in the calculation.

But the ships that were by far the most healthy were those that had been the longest from England, the Ajax, Russel, Montague, Royal Oak, and Prudent. There had been formerly a great mortality in all these ships; and it would appear that this uncommon degree of health was owing, in some measure at least, to this circumstance, that the most weakly had been swept off by the different distempers to which they were exposed; so that only the more hardy and robust had survived.

Under the head of “Other Complaints,” a much smaller number were put on the list, and still fewer died, in this than the preceding month. This difference is owing to the number that died of wounds last month.

There died on board, in the course of this month, thirteen of fevers, seven of fluxes, and seven of other complaints, of whom five died of small pox, one of asthma, and one of wounds he received at St. Christopher’s.

In order to show more fully and minutely what are the complaints incident to fleets in this climate, I shall set down a list of the numbers taken ill of the different diseases and accidents during this month, extracted from the returns of twenty-eight ships of the line, and two frigates.

The number of ulcers bears here a smaller proportion to the whole than it does in general to the sum total of the sick list; for being the most tedious of all complaints, they consequently accumulate more than any other. Thus many of the cases now set down as slight accidents, will, in the ensuing month, be in the state of obstinate ulcers.

Most of the diseases of one hot climate resemble those of another, so far as I know; but there is one disease which we hear of as being extremely prevalent all over the East Indies, which is hardly ever met with in the tropical regions of the West. This is the inflammation of the liver, of which I remember to have seen only one well-marked case, and it was that of a gentleman who had been in the East Indies, and had been subject to it there: nor do I recollect more than one, or at most two, cases of this sort out of several thousand cases of various diseases that were reported to me. This is either owing to the greater heat and dryness of the air in the East Indies, or some other peculiarity with which we are not acquainted12.

Every other inflammatory complaint exists more or less, though they are much rarer than in cold and temperate climates. The phthisis pulmonalis is not so common as in cold climates, but proves sooner fatal to most constitutions. There are certain pulmonic complaints, particularly those of the asthmatic kind, to which the climate of the West Indies is remarkably favourable; but those in which there are tubercles and ulceration seem to be hurried faster to a fatal termination. The climates, from the thirtieth to the fortieth degree of latitude, seem to be best suited to consumptive complaints. The rheumatisms that occur in hot climates are mostly of the chronic kind.

CHAP. III

State of Health of the Fleet in April 1782 – Battles on the 9th and 12th – The Fleet very healthy – from the Quality of Provisions – from the Effects of Victory – Advantages of close Action – What Diseases most prevalent – Extraordinary Degree of Health in the Formidable.

This month being interesting, on account of the memorable engagements that happened in it, the remarks shall, for this reason, be somewhat more full and particular.

Three ships of the line having been sent to protect convoys to Jamaica, and one having been sent to protect a convoy to Barbadoes, there remained thirty-six at St. Lucia in the beginning of this month. By the end of the first week their damages were repaired, their water and provisions complete, and the sick in a great measure recovered.

An equal force of the enemy lay over against us at Martinico, the two powers of Britain and France being to make this distant quarter of the world the theatre for trying their strength, and deciding the sovereignty of the seas. In the view of this great event, our commander forwarded the necessary duties of the fleet with such zeal and diligence, and watched the motions of the enemy with such vigilance, that he overtook their grand squadron a few hours after they left their own port, and engaged them two several days, with a success, glorious and complete.

Nothing had been wanting to equip this fleet for the great and decisive exertion it was to make. Every ship, except two, might be said to be healthy, most of them were complete in men, well appointed with officers, and well found in stores and provisions. – Conformable to this was the eagerness, the confidence, and resolution, which led them to success and victory.

After this battle, the whole fleet, with the prizes, bore away for Jamaica, where part of it arrived on the last days of April, but the greater part of it kept the sea, till after the middle of May.

As this month is more than usually interesting, the tables are given at full length, and a column is added for the wounded.

The sum total, of the numbers of the men on board of the thirty-six ships that composed the line of battle on the 12th of April, was 21,608, and the mortality during the month, exclusive of those who were killed or died of wounds, was one in 862.

There was less sickness, and less death, from disease in this month, than any of the former twenty-three months, in which I kept records of the fleet, and less than in any subsequent month, till the fleet got to the coast of America.

To account for this, it is to be observed, that the men had not been exposed to the noxious air of the shore in watering, as in the preceding month: they had received from England a fresh supply of provisions, among which was sour krout, melasses, and essence of malt, all in addition to the ordinary articles of victualling: many of the ships were supplied with wine, in place of rum, and as the weather was all along dry and fine, the men suffered the less from the exposure and want of sleep, which are the necessary consequences of keeping ships clear for battle for several days and nights together.

In the Spaces marked thus, §, no Return was made.

Might not this extraordinary degree of health have also been owing, in part, to the effects of success upon the spirits of the men? It is related13, that, when the fleet under Admiral Matthews was off Toulon, in daily expectation for some time of engaging the combined fleet of France and Spain, there was a general stop put to the progress of disease, particularly of the scurvy, from the influence of that generous flow of spirits, with which the prospect of battle inspires British seamen. But if the mere expectation and ardour of a battle, without any happy event, could have such a sensible effect, what must have been the effect of the exultation of VICTORY, a victory in which the naval glory of our country was revived and retrieved, after a series of misfortunes and disgraces, which had well nigh extinguished the national pride in every department of service! The plain and honest, though unthinking seaman, is not less affected by this than the more enlightened lover of his country. Even the invalids at the hospital demonstrated their joy, upon hearing of this victory, by hoisting shreds of coloured cloth on their crutches.

It would appear, that there is something in situations of exertion and danger, which infuses a sort of preternatural vigour. When the mind is interested and agitated by active and generous affections, the body forgets its wants and feelings, and is capable of a degree of labour and exertion, which it could not undergo in cold blood. The quantity of muscular action employed in fighting at a great gun for a few hours, is perhaps more that what is commonly employed in a week in the ordinary course of life, and though performed in the midst of heat and smoke, and generally with the want of food and drink, yet the powers of nature are not exhausted nor overstrained; even the smart of wounds is not felt; and the future health of those who survive unhurt by external violence is so far from being injured, that it is sometimes mended by this violent, but salutary agitation.

The loss in action, and the number of mortal wounds, were not so great as might have been expected in a battle continued for a whole day. This advantage was owing to the superiority of our fire, as well as to the closeness of the fight, of which the Commander in Chief set the illustrious example, by penetrating the enemy’s line with his own ship; a bold and singular effort which first decided the event of the day. When ships in action are opposed to each other at a small distance, the velocity of cannon balls is so great, that in penetrating a ship’s side, few or no splinters are torn off; and by these more men are commonly killed and wounded, than by the ball itself. For the same reason, a close shot does less damage also to the ship itself, than a distant one; for a quick-flying ball makes an aperture less than its own diameter, whereas a spent one produces innumerable deadly splinters, at the same time shivering the object it strikes, and making wide and extensive rents in it. The proportion of the wounded to the killed, is also greater in distant, than in close fight, on account of the great number of small splinters; and we have an experimental proof of this, in comparing the action in Fort Royal Bay in April 1781, with this near Dominica in April 1782. In the former, the enemy having kept far to windward, and engaged at a great distance, the proportion of the wounded to the killed was considerably more than four to one14; whereas in the latter, where the greater part of the battle was close, the proportion of the wounded to the killed, was little more than three to one15.

Though it is a remark not belonging to a medical work, yet it may be observed, that the greatest advantage that arose to us from close action was, that the fire of the enemy was thereby silenced; for the advantages would be mutual and equal, on the supposition, that the French, in such a situation, were to keep the deck, and stand to their guns equally well with the British seamen.

It appears, by examining the table, that the ships in which the fevers chiefly prevailed this month, were those that came last from England, and that those in which the fluxes prevailed most were chiefly of the squadron we found on the station, namely, the Canada, Resolution, and Prince William. The latter however recovered greatly in the course of this month. Some of the Ships that arrived last from England, namely, the Arrogant, Prothée, and Anson, were also considerably afflicted with fluxes, but they were of an extremely mild kind; and the small number of deaths from this disease in comparison with those from fevers, is a proof of a former observation, that this is the safest form in which an acute disease can shew itself. This small degree of mortality was also owing to the judicious method of treating it which was in general practised throughout the fleet; and it is but justice to the medical gentlemen to say, that they shewed on this, as well as every other occasion, great skill and attention in the treatment of the sick and wounded.

The sum total of fevers and fluxes that have been put on the list this month, is much the same as that of the preceding month; but the proportion of fluxes in April is much greater.

The proportion of scurvy is somewhat increased; which is not to be wondered at, when it is considered, that though the fleet had not been so long at sea as is necessary to produce it, especially in this climate, yet the men having had no refreshments when last in port, may be considered as having been all that time at sea.

The superior degree of health in this month will appear in a still stronger light, if we cast our eye on the column expressing the number sent to the hospital, the proportion of which is, comparatively, very small.

The ships that had been the longest from England, were still among the most healthy. But of all the fleet, none was so free from sickness and mortality as the Formidable. No man belonging to this ship died of disease for the first four months after sailing from Plymouth, though there were at times 900 men on board, and never less than the established complement, which is 750; and so few were taken sick in that time, that only thirteen were sent to hospitals, and their complaints were small-pox and ulcers.

This ship left England provided with every thing that could be supposed to conduce to the health of men, and may be considered as an experiment to prove what degree of health may be attained by proper management and attention. She was furnished not only with abundance of sour krout, melasses, and essence of malt, in common with the other ships; but what was peculiar to her, was an entire supply of excellent wine, in place of spirits, of which none was used during the period mentioned.

CHAP. IV

Account of the Health of the Fleet while it lay at Jamaica during May, June, and Part of July, 1782. – French Prizes Causes of Sickness – Their Difference from the English in point of Cleanliness and Discipline – Bad Effects of Land Wind and Watering Duty – Situation of Port Royal – Season uncommonly dry and windy – Fluxes more prevalent at Sea than in Harbour – Comparison of the Sickness at this Time with that of the Army and with that of the Squadron under Admiral Vernon forty-one Years before – Effects of Contagion and foul Air – Officers more affected than the common Men.

All the squadron that was left to windward of Jamaica, consisting of twenty-four ships of the line, kept the sea during great part of May, the last division of it not having come to Port Royal till the 25th of that month.

The whole fleet remained in harbour during the remainder of the month, and the whole of the next, except the Warrior, Prothée, and Russell; the two former were sent on a cruise, in which the Warrior continued quite healthy, as she had been ever since her arrival from England; and in the Prothée a great check was given to the fevers and fluxes which had begun to prevail at Port Royal. The Russell was sent to England with a convoy.

Table, shewing the proportional Prevalence of Sickness and Mortality in May

Transcriber’s Keys:

A Proportion of those taken ill or wounded in the Course of the Month.

B Proportion of those that died in relation to the Numbers of Sick or wounded.

The whole number of sick on board on the first of this month, in thirty-six ships of the line and two frigates, upon which the preceding calculation is formed, was one thousand four hundred and eighteen. The whole number taken ill in the course of the month was two thousand eight hundred and twenty-eight; the number sent to the hospital was one hundred and seventy-three; and there died on board ninety-four.

The proportion of those who died this month, in relation to the whole number on board, was one in two hundred and eighty-seven.

There was a considerable increase of sickness and mortality this month in all the common diseases, and chiefly in that part of the squadron which was in port. There was less increase in the number of fevers than either of the other two epidemics; but such was their increased malignancy, that more died of them than of both the others. The number of fluxes was more than double of what it was the preceding month, and the mortality from them was also in a much greater proportion, as may be seen from the Tables.

The fevers prevailed chiefly in port, and the fluxes at sea. A good many of the latter, indeed, arose in the Alcide, though constantly in port; but this seemed to be owing to contagion conveyed by some British soldiers, who were sent on board of this ship after being retaken in one of the French men of war, several of whom were ill of this disease. But there were few fluxes in those ships at Jamaica in which the most malignant fevers appeared. There were a few in those in which the fevers arose from the air of the marshes on the watering duty; but there were none on board of the French prizes, nor in those ships in which that sort of fever was which proceeded from a similar cause, that is, filth and animal effluvia. Upon the whole, in those ships in which the fever was most malignant, there the fewest fluxes were found.

Several circumstances contributed to the increase of sickness and mortality this month.

1st. The infection, or rather the foul air, of the French prizes, in most of which a very bad fever broke out among the officers and men that were sent from the ships of our fleet to take charge of them.

The discipline and internal œconomy of the French ships of war are greatly inferior to those of the British. Their decks are never washed, and there is a great defect in every point of cleanliness and order. The free course of the air is obstructed by lumber of every kind, and by bulkheads, which are not taken down even in the time of battle; and the gratings are covered night and day with tarpaulins, even in a hot climate. There are not even scuppers opened on the lower deck as outlets to the water and filth, which necessarily accumulate there, and for which the only vent is a pipe contrived on purpose, passing from that deck along the ship’s side into the hold, which becomes thereby a common sink, inconceivably putrid and offensive. And in addition to the ordinary causes of corruption, there was one peculiar to the occasion; for the blood, the mangled limbs, and even whole bodies of men, were cast into the orlop, or hold, and lay there putrifying for some time. The common sailors among the French have a superstitious aversion to the throwing of bodies overboard immediately after they are killed, the friends of the deceased wishing to reserve their remains, in order to perform a religious ceremony over them when the hurry and danger of the day shall be over. When, therefore, the ballast, or other contents of the holds of these ships, came to be stirred, and the putrid effluvia thereby let loose, there was then a visible increase of sickness. For the first three weeks after the capture, the stench proceeding from the numbers of wounded men contributed also to taint the air.

The Ville de Paris was much more sickly than the other prizes, not only from her being larger, and thereby containing a greater mass of foul air, but by receiving the surviving part of the crew of the Santa Monica, one of our frigates, which had been cast away on the Virgin Islands, and whose men were so reduced by hardship and intemperance, that most of them were taken ill as soon as they came to breathe the unwholesome air of the French prize. To whatever cause it was owing, the fever was much more violent here than in the other prizes, and it generally carried men off on the third or fourth day; and what is remarkable, the officers were affected by it in a greater proportion than the common men. One lieutenant, and every warrant officer, except the boatswain, died of it. This was a proof that the sickliness was owing to the bad air, and not to the intemperance and irregularity so usual on board of prizes, which only the common men give into; and the probable cause of the officers being most affected is, that they were accustomed in common to a purer air, by living in the most clean and airy parts of the ship.

It is also remarkable, that the Ville de Paris was healthy when taken, and had been so ever since leaving France in March, 1781; nor had any other of the captured ships of the line been sickly for some time before, except the Ardent, when she arrived at Martinico four months before, at which time the greater part of the crew were sent to the hospital with fevers. This, as well as other facts of the same kind, tends to prove, that when men come to be much habituated to bad air, their health is not affected by it.

The French ships were purified by washing and scraping, by fumigating daily with gunpowder and vinegar, and by the use of wind sails; but nothing seemed to contribute so much to sweeten the air in them as burning fires in the hold; for this tended both to make the putrid matter exhale, and to carry it off, by producing a perpetual change of air. Captain Curgenven, who at this time commanded the Ville de Paris, had great merit from his very assiduous and successful endeavours in so difficult a duty as the management and equipment of this great ship. In consequence of the judicious measures taken, and the men becoming more used to the bad air, the sickness ceased in the course of a few weeks.

In the accounts given in the tables, the French prizes are not included, for the disorderly state in which they were at this time prevented my receiving regular returns: but having made inquiry concerning the mortality in the Ville de Paris, I found, that of a crew of three hundred and twelve men, there died ten in the month of May, and there were thirty sent to the hospital, whose cases were so unfavourable, that about one half died. The only diseases were fevers. The surgeon of the Ardent told me about the same time, that one third of the crew of that ship was ill of fevers.
