Medicine at Sea

Medicine Disease Amputation
The Medicine Chest
In 1720 Bartholomew Roberts and the pirates who sailed with him found themselves in a heated battle with pirate hunters. His only option was to “cut and run,” so the pirates dumped their guns and cargo overboard. They eventually escaped, but not without severe damage to the Fortune and her crew. Half were dead or wounded, and many more would die, for their surgeon Archibald Murray had left the ship and no one else knew how to amputate limbs or prevent gangrene. Having no other options, the wounded were given enough rum to lessen their pain and left to die.
This is but one account of how sailors fared without a doctor to tend them. If the ship possessed a medicine chest, the captain designated someone to tend patients. That person needed to be able to read and write, but if he lacked knowledge of Latin, deciding which medications to give became a problem since bottles were labeled in that language, rather than the language of the tender. If the ship lacked a medicine chest, a wounded or ill pirate found his fate in God’s hands. When William Phillips injured his leg, Captain John Phillips allowed John Rose Archer to tend the man. Archer had some skill with a saw, but cauterization was beyond his understanding. The red-hot axe he used to burn the stump destroyed too much and William was left with even worse wounds than before.
Surgeons who plied their trade at sea, rather than on land, were not new. They sailed with Roman warships, and during medieval times, they accompanied nobility and prelates on their voyages. When the Spanish Armada sailed in 1588, the eighty-five surgeons and their assistants were unable to stop the dysentery and typhus that swept the ships.
John Woodall’s The Surgeons Mate, first published in 1617, aided many in treating what ailed a ship’s crew. The manual listed the instruments and medicines found in the medicine chest, and explained how to use them. Special instructions explained what to do for medical emergencies, such as an amputation. Various ailments were also discussed, especially scurvy. Woodall provided his readers with 281 remedies, but of the herbs used, he warned that only fourteen were “most fit to be carried:” rosemary, mint, melilot, clover, horse radish, comfrey, sage, thyme, absinthe, blessed thistle, balm mint, juniper, hollyhock, pyrethrum, and angelica. Among the tools and supplies found in medicine chests were knives, razors, “Head-Sawes,” cauterizing irons, forceps, probes and spatulas for drawing out splinters and shot, syringes, grippers for extracting teeth, scissors, “Stitching quill and needles,” splints, sponges, “clouts” (soft rags), cupping glasses, blood porringers, chafing dishes, mortar and pestle, weights and scales, tinderbox, lantern, and plasters. This was why medicine chests were prized almost as much as gold. In fact, when Blackbeard blockaded the port of Charleston, South Carolina, he demanded such a chest in exchange for his hostages – leading citizens of the town. Contemporary accounts detailing the incident placed the value of the medicine chest at between £300-400.
Unlike today, medicines of the past had to be put together similar to how a cook bakes a cake. The recipe for a medication consisted of a curative agent, water or oil, flavoring, and the compound used to comprise how the medication was given, for example as a pill or an ointment. The base for the latter might have been glycerin or lard. Wax sometimes held a pill together. Ingredients in ointments and liniments might include mercury, turpentine, sassafras, thyme, hemlock, eucalyptole, and/or sulfur. Medicines that were ingested usually needed some flavoring to make them palatable; vanilla, honey, licorice, sugar, nutmeg, ginger, and mint are some that were used. Depending on what ailed the patient, the pirate might endure bloodletting to remove toxins from the blood, blisters (a caustic agent applied with flannel or leather), salves, clysters (medicines given rectally), or hot, moist cloths used to relieve pain.
Perhaps Blackbeard required the medicines and instruments to treat syphilis, a common plague among sailors and pirates who frequented brothels when on shore. Of course, his crew might also have suffered from any number of other problems, for danger lurked almost everywhere aboard a wooden ship. Aside from the rats, weevils, lice, and cockroaches, livestock was kept aboard and sometimes had free reign of the deck, making for unsanitary conditions. The pirates’ clothing was often wet or damp. Depending on where they sailed, nature might also inflict hardships: sunburn, heat exhaustion, sun stroke, hypothermia, exposure, or frostbite. Their work was equally hazardous and sores, cuts, and bruises were the norm. Scurrying up or down the rigging and the frequent movement of both the ship and the mast sometimes caused sailors to lose their footing and fall. Landing in the water often meant the man drowned, for knowing how to swim wasn’t a requirement for being either a sailor or a pirate. If he was lucky enough to be retrieved from the water, sailors held the victim by his heels and shook him to remove any water in his chest.
Landing on the deck might fracture a person’s skull or kill him. In 1833 Billy Bridle1 was aloft in the topmast crosstrees. When he tried to slide down the topgallant halyards, he burned his hands, lost his grip, fell to the deck (a distance of twenty feet), and died instantly. Those who didn’t die from a fall often exhibited symptoms of “lethargie or frenzie, madnesse, losse of memory, deadish sleep, giddinesse, apoplexie, paralysis, and divers other like accidents.” (Friedenberg, 14) From the seventeenth through the nineteenth centuries, surgeons treated such head wounds with desiccation and cicatrization. When the skull bone collapsed, he raised the depressed fragments and removed any splinters. Wounds to the chest and abdomen, however, were left in God’s hands.
Pirates, who visited lands not explored before, also encountered additional dangers. Alexandre Exquemelin wrote of the insects on Hispañola:The gnats of the third species exceed not the bigness of a grain of mustard. The colour is red. These sting not at all, but do bite so sharply upon the flesh as to create little ulcers therein. When it often comes that the face swells and is rendered hideous to the view, through this inconvenience. (Esquemeling, 33)The plants could be equally dangerous. He encountered a dwarf apple tree near the shore. Although similar to apples back home, the fruit was poisonous.…these apples being eaten by any person, he instantly changes colour, and such an huge thirst seizes him as all the water of the Thames cannot extinguish, he dying raving mad within a little while after…. This tree affords also a liquor, both thick and white…which, if touched by the hand, raises blisters upon the skin, and these are so red in colour as if it had been deeply scalded with hot water. One day being hugely tormented with mosquitos…and as yet unacquainted with the nature of this tree, I cut a branch thereof, to serve me instead of a fan, but all my face swelled the next day and filled with blisters, as if it were burnt to such a degree that I was blind for three days. (Esquemeling, 32)Depending on a pirate’s ailment, the surgeon might prescribe one of nine different types of medicines. Aquae – such as cinnamon water, licorice juice, and fortified peppermint water – cured hiccups and “stoppeth vomiting, cureth choler, griping paine of the belly…” according to John Woodall. (Druett, 7) Spirits, salts, and tinctures – like salts of wormwood, vinegar, and quicksilver – cured a variety of ills from urinary problems to fever. Balsams and resins were given orally or applied to the skin. Sanguis Draconis, also known as Dragon’s Blood, was the resin made from the agave and rattan palm. Garnet in color, the ground powder was an astringent and “closeth up wounds.” (Druett, 8) It was also used to make the varnish used on violins. Around 1640 Jesuit priests introduced Peruvian bark (quinine) to Europe from South America. It was used to cure intermittent fevers, such as malaria.It should be taken in the intermissions between the hot stages, in the dose of a grain every hour, an emetic at the commencement of the chill, and a purge of Calomel and Jalap afterwards having been given before commencing with the quinine. (Druett, Rough Medicine, 61)Syrups were made from almonds, red roses, saffron, lemons, and other plants. On board a ship, the surgeon might mix vinegar of squills (hyacinth) with sugar and honey, before giving it to a pirate to clear mucus from his bronchial tubes. Oleum or oils, like oil of St. John’s Wort, were applied to the skin. Scottish surgeons may have used this to treat wounds. The Scots believed that St. Columba favored the plant because it was associated with John the Evangelist and the Virgin Mary, although the plant was used long before Christianity came to Scotland in sacred ceremonies and to prevent “fairies from spiriting people away while they slept.” (Darwin, 96) Opiates and theriacs were also used. An early patent medicine with opium in it was “Methridatum,” which Woodall recommended for those “fearfull of waters” and to cure “the bites of serpents, mad dogs, wild beasts, and creeping things” (Druett, 8), all of which a pirate might encounter when visiting exotic places. Unguents were used to treat burns and abrasions.
Plasters drew bad humors from the body or to treat open infections, such as wounds received in battle. In 1500 Giovanni de Vigo, a Roman doctor, treated syphilis with a poultice called Emplastrum de Ranis cum Mercurio. Its ingredients consisted of frogs, “earthworms, viper’s flesh, human fat, wine, grass from northern India, lavender from France, chamomile from Italy, white lead, and quicksilver.” (Druett, 9) One of the oddest plasters was Pracelsi and was used to treat wounds sustained in battle. The ingredients, brewed in autumn, included “burnt earthworms, dried boar’s brain, pulverized Egyptian mummy, crushed rubies, bear’s fat, and moss from the skull of a hanged man which had been collected from the gibbet at moonrise with Venus ascending.” (Druett, 9) One might think the plaster was then applied to the soldier’s wound, but in fact it was applied to the sword that sliced him.
The last type of medicine came from herbs and roots. Chamomile flowers soothed headaches and helped with kidney problems. Other examples included wormwood, cinnamon, saffron, rose petals, juniper berries, sarsaparilla root, mustard seeds, and ginger.
The most common type of ailment that surgeons treated was a disease of some kind. To men like John Woodall, sin was the primary cause of disease, although the noxious fumes emanating from bilge water ran a close second. Aside from living a moral life – not something usually associated with pirates – the best way to stay healthy was to avoid stinking vapors and cemeteries whenever possible, and protect oneself from the night air. Diseases, however, had a nasty habit of invading ships where large numbers of people were gathered together in confined places. Surgeons recognized this fact early in the fifteenth century. It was one reason that Sir Francis Drake had to curtail some of his expeditions against the Spaniards in the West Indies. He wrote in his journal:…we were not many dayes at Sea but there began amongst our people such mortality, as in a few dayes there were dead above two or three hundred men. And until some, seven or eight dayes after our coming from Saint Jago, there had not dyed any one man of sicknesse in all the Fleet: the sicknesse shewed not his infection, wherewith so many were stroken untill we were departed thence, and there seazed our people with extreeme hot burning and continuall ague, whereof some very few escaped with life and yet those for the most part not without great alteration and decay of their wits and strength for a long time after. In some that dyed were plainly shewn the small spots, which are often found upon those that be infective with Plague. (Friedenberg, 16)The actual disease Drake described remains unknown, but it might have been typhus, cholera, yellow fever, or bubonic plague. He believed the night air was the culprit for the affliction. Even the surgeon died, and Drake returned home without any plunder to make up for the sacrifices he and his men endured.
Among the artifacts recovered from the wrecks of Black Sam Bellamy’s Whydah and Blackbeard’s Queen Anne’s Revenge were pewter syringes. These were used to administer mercury to those who suffered from syphilis. First described in Europe in 1494, the name stems from a poem Girolamo Frascatoro wrote in 1530 about a shepherd named Syphilisive Morbus Gallicus. The term “syphilis” wasn’t really applied to the disease until the 1800s. Spanish sailors called it the French pox, while the French called it the Spanish Disease.
What did a pirate endure if he contracted syphilis? The disease has three stages.An early treatment2 for syphilis came from the native peoples in the West Indies. They used a resin found in evergreen holy wood or guaiacum. The more effective treatment, though, was to administer mercury orally, through a vapor bath, or in the case of pirates, by injecting the medication into the penis with a syringe. A salve was applied to the chancres that developed when first contracted.
- Chancres form where contact with an infected person occurred. These often heal, leaving small scars.
- Six to eight weeks later, the pirate seemed to contract the flu and developed a skin rash. Doctors often misdiagnosed this stage because of its resemblance to small pox and measles. The patient soon recovered and believed himself cured. During this stage, syphilis was contagious, and the pirate often infected many others. After two years, the disease entered a dormant stage.
- The final stage occurred when syphilis attacked the body’s systems many years later. Many went mad or blind before they died.
Since syphilis was more or less an occupational hazard, surgeons treated most pirates over a long period of time. Whether the mercury was ingested orally or absorbed through unguents, it often produced a metallic taste in his mouth that caused patients to salivate. They didn’t complain overmuch since many thought it was just the price they paid for contracting the disease in the first place. Mercury poisoning, however, sometimes occurred. When this happened, the pirate lost weight, drooled, had foul breath and blurred vision, and slurred his speech. He also had trouble maintaining his balance. If the treatment for syphilis wasn’t stopped, his kidneys eventually ceased functioning and he died.
Another disease that plagued anyone who remained at sea for long periods of time was scurvy, which killed more mariners than all the other diseases, natural disasters, and fights combined. Historians conservatively place the number of deaths at more than 2,000,000 between Columbus’ first voyage to the New World and the mid-nineteenth century. Even physicians of Ancient Greece didn’t know what caused it. A variety of folk cures were developed, some of which were more deadly than the disease. Among these were swallowing sea water to purge the illness, bleeding, digesting sulfuric acid, anointing open sores with mercury paste, and increasing the sailor’s workload. The thinking on the last cure was because scurvy made the sailor lethargic.
Scurvy usually struck about four weeks after a ship left port. In 1596 William Clowes, an English surgeon at sea, described what his men suffered:Their gums were rotten even to the very roots of their teeth, and their cheeks hard and swollen, the teeth were loose neere ready to fallout…their breath a filthy savour. The legs were feeble and so weak, that they were not scarce able to carrie their bodies. Moreover they were full of aches and paines, with many bluish and reddish staines or spots, some broad and some small like flea-biting. (Brown, 34)Just like the pirates and sailors, those who treated them sometimes endured the same disease. Another surgeon who sailed on an English ship in the sixteenth century wrote:It rotted all my gums, which gave out a black and putrid blood. My thighs and lower legs were black and gangrenous, and I was forced to use my knife each day to cut into the flesh in order to release this black and foul blood. I also used my knife on my gums, which were livid and growing over my teeth…. When I had cut away this dead flesh and caused much black blood to flow, I rinsed my mouth and teeth with my urine, rubbing them very hard…. And the unfortunate thing was that I could not eat, desiring more to swallow than to chew…. Many of our people died of it every day, and we saw bodies thrown into the sea constantly, three or four at a time. For the most part they died without aid given them, expiring behind some case or chest, their eyes and the soles of their feet gnawed away by the rats. (Brown, 34)Sir Francis Drake recorded several outbreaks of scurvy. In 1740 Commodore George Anson set sail with 2,000 men on a trip to circumnavigate the world. Of those original sailors, only about 200 returned to England in 1744. Ninety percent of those who died succumbed from scurvy.
Sir Richard Hawkins, another Elizabethan Sea Dog, referred to it as “the plague of the sea, and the spoil of mariners.” (Druett, Rough Medicine, 142) In 1593 he was the first to suggest a remedy: “most fruitfull for this sicknesse, is sower oranges and lemons.” (Druett, Rough Medicine, 143) Johan Friedrich Bachstrom believed scurvy developed because of the lack of fresh fruits and vegetables. When he announced this in the 1730s, his fellow practitioners ignored him because no one else believed this to be true. In 1753 James Lind published a Treatise of Scurvy, but like Bachstrom his advice was largely ignored. Another forty-two years passed before Sir Gilbert Blane convinced the British Admiralty to provide sailors with a daily ration of lemon juice. In doing so, the navy virtually eliminated scurvy from their ships.
While pirates preferred not to engage in a sea battle, fighting did occur. Sometimes it was confined to the actual boarding of the prize, but sometimes the hunter and prey exchanged volleys from their guns. The injuries inflicted were bloody and sometimes lethal. After the American frigate United States defeated HMS Macedonian on 25 October 1812, a British seaman wrote:The first object I met was a man bearing a limb, which had just been detached from some suffering wretch…. The surgeon and his mate were smeared with blood from head to foote: they looked more like butchers than doctors….James Lowry served as a Royal Navy ship’s surgeon in the Mediterranean fleet when it attacked Fort Saint Elmo on Malta in December 1798. His words clearly give witness to the dangers during a sea battle, and to the fact that during a fight, there was no time to mourn the dead.
Our carpenter…had his leg cut off. I helped to carry him to the after wardroom, but he soon breathed out his last life there, and then I assisted in throwing his mangled remains overboard…. It was with exceeding difficulty I moved…it was so covered with mangled men and so slippery with blood…. (Estes, 65)As I was dressing a wounded man, a cannon ball struck a young gentleman on the head dashing his brains upon all sides; part of them blinded me. At this moment a splinter struck my head and rendered me insensible for quarter of an hour. Upon my recovery, I could hardly persuade myself but what I was mortally wounded, from being completely besmeared with blood and brains. Alas! when I beheld my friend and companion without a head, I could not avoid reflecting with emotions of grief; but the field of battle being no place for weeping or lamentations…I contented myself with the usual expression upon the field of battle – poor fellow, there he lies and ends his career. (Lowry, 44)When a pirate lay hurt, he usually suffered from a puncture, a slash, or an amputation. Bullets, shrapnel, and splinters often caused the first type of wound, whereas a cutlass or knife caused the second. Projectiles – such as ball, shot, or chain – inflicted the last type of injury. These could inflict a variety of wounds, especially if the projectile struck wood. Splinters flew or a mast toppled, crushing anyone unlucky enough to be under it when it fell. Gunners suffered scorched burns from spilled gunpowder ignited by a spark. Descriptions of Dominique You, one of Jean Laffite’s privateers, mention powder burns over his left eye that gave him a menacing or grim appearance. If an explosion caused a fire, sailors often suffered severe burns.
A wounded pirate eventually found himself placed upon planks laid across casks to form a makeshift operating table, if a real table wasn’t available. An old sail or other cloth might be draped over the planks. Nearby smaller flat surfaces or sea chests held the surgeon’s instruments and on the floor was a bucket where amputated body parts were dropped until they could be carried above deck and tossed into the sea.
Drake, like the buccaneers who came later, often raided land targets. During one such raid, the party was ambushed and he was wounded.The generall himself was shot in the face under his right eye and close by his nose, the arrow piercing a marvelous way in under basis cerebris with no small danger of his life besides that, he was grievously wounded in the head. The rest being nine persons in the boat, were deadly wounded in divers parts of their bodies, if God almost miraculously had not give cure to the same. For our chief Surgeon being dead and the others absent by the loss of our vice-admirall, and having none left us but a boy, whose good will was more than any skil he had, we were little better than altogether destitute of such cunning and helps as so grievous a state of so many wounded bodies did require. Notwith standing God, by the very good advice of our Generall and the diligent putting too of every man’s help, did give such speedy and wonderful cures, that we had all great comfort thereby and yielded God the glory, whereof. (Friedenberg, 17)Doctors didn’t know what caused infection back then, so instruments weren’t sterilized and bandages weren’t necessarily clean. Neither did the surgeon wash his hands between patients. To tend a puncture or slash wound, he removed “unnatural things forced into the wound” (a musket ball, pieces of wood or cloth), using a forceps. (Friedenberg, 11) Then he washed the wound with water or alcohol, packed it with lint scraped from linen sheets, and wrapped a bandage around it. If sutures were needed, he used waxed thread that might dangle from his lips until needed. Should infection set in, the preferred treatment was to bleed the patient.
A pirate who suffered a severe wound to his arm or leg, though, was more likely to have it amputated since the tissue and muscle were severely damaged. The last thing anyone wanted was to have the wound turn gangrenous, for that usually resulted in death. Most doctors believed the patient was more likely to survive if a clean cut was made, than if the surgeon allowed the limb to heal without surgery. John Hoxse, a carpenter aboard the USS Constellation in 1800, wrote:…as I was standing near the pump, with a top maul in my right hand, with the arm extended, a shot from the enemy’s ship entered the port near by, and took the arm off just above the elbow, leaving it hanging by my side by a small piece of skin; also wounding me severely in the side, leaving my entrails all bare. I then took my arm in my left hand, and went below…and requested the surgeon to stop [the bleeding in] my arm [as it] was already off. He accordingly stopped the effusion of blood, and I was laid aside among the dead and wounded, until my turn came to have my wounds dressed…. I was so exhausted that I fell asleep…until…I was…laid on a table, my wounds washed clean, and my arm amputated and thrown overboard. (Langley, 58)Hoxse received these wounds during the Quasi-War with France, but didn’t record the event until forty years later.
When amputation was required, it had to be done within twenty-four hours of the wounding. The seaman aboard HMS Macedonian assisted during an operation.We held [one man] while the surgeon cut off his leg above the knee. The task was most painful to behold, the surgeon using his knife and saw on human flesh and bones as freely as the butcher at the shambles. (Estes, 65)An injured pirate’s clothing was cut off and a tourniquet was applied to slow the bleeding. The surgeon gave him a stick to bite down on, and while the ship pitched and rolled, the operation began. First, the surgeon used a scalpel to cut open the skin above the wound. He sliced through the muscle to the bone with a knife. The mate who assisted pulled back the flesh to expose the bone and a leather strap encircled the bone to keep it clear of obstruction. Using a saw, the surgeon then cut the bone and tossed the removed limb into the bucket.A strip of cotton cloth about 2 feet long and 8 inches wide torn up the centre from one end for half the length is then to be drawn over the flesh closed around the bone. The ends are brought together and the whole serves to draw the skin and flesh up while the bone is sawed off. Very little pain is felt from sawing a bone – If there is any splinter or corner left it should be pinched off with nippers.3Hot tar was painted on the bloody stump or the wound was cauterized with a hot iron.4 This stopped the profuse bleeding that occurred. Once the surgeon removed the tourniquet, he placed two large “rounds” of linen over the stump and lashed it in place with strips of linen. If a wool stocking cap was available, this was also pulled over the stump. The entire operation took eight to ten minutes. The pirate’s chances of survival? Fifty-fifty.
Contrary to what most people believe, the injured underwent surgery wide awake. They weren’t given rum or other alcoholic drinks to numb them for two reasons. Anesthetics had yet to be invented and the doctors didn’t want their patients dying from weak hearts. Opiates or grog weren’t given to them until after the operation to relieve pain.
Sometimes there was nothing a surgeon could do to help a wounded man. When this happened, he often died a slow and painful death. Robert Young, the surgeon aboard the Ardent at the Battle of Camperdown in 1797, wrote:Joseph Bonheur had his right thigh taken off by a cannon shot close to the pelvis, so that it was impossible to apply a tourniquet; his right arm was also shot to pieces. The stump of the thigh, which was very fleshy, presented a dreadful and large surface of mangled flesh. In this state he lived near two hours, perfectly sensible and incessantly called out in a strong voice to me to assist him…. All the service I could render…was to put dressing over the part and give him drink.While pirate surgeons lacked a full understanding of what caused disease, they labored as best they could to cure ship fever (typhus), gripes and fluxes (dysentery), smallpox, measles, pleurisy and catarrhal fever, scurvy and beriberi, food poisoning, venereal disease, yellow fever, and malaria. The same was true for serious wounds and injuries. Some surgeons, like Alexandre Exquemelin and Lionel Wafer, studied and used the cures recommended by the people native to the various lands the buccaneers visited. Pirates understood the value of having a surgeon amongst them. That’s why doctors and medicine chests were prized plunder.
