Malarial mosquitoes helped defeat British in battle that ended Revolutionary War

Was it warmer in Virginia in 1781 than it is today, or has our capacity to cope been enhanced? In fact, climate does not determine our well-being.  Unfortunately, climate change policies might, and for the worse.

Major combat operations in the American Revolution ended 229 years ago on Oct. 19, at Yorktown. For that we can thank the fortitude of American forces under George Washington, the siegecraft of French troops of Gen. Jean-Baptiste Donatien de Vimeur, the count of Rochambeau – and the relentless bloodthirstiness of female Anopheles quadrimaculatus mosquitoes.

Those tiny amazons conducted covert biological warfare against the British army. Female mosquitoes seek mammalian blood to provide the proteins they need to make eggs. No blood meal, no reproduction. It makes them bold and determined to bite.

Some anopheles mosquitoes carry the malaria parasite, which they can inject into human bloodstreams when taking their meals. In eastern North America, A. quadrimaculatus was the sole important malaria vector. It carried malaria from person to person, and susceptible humans carried it from mosquito to mosquito. In the 18th century, no one suspected that mosquitoes carried diseases.

Malaria, still one of the most deadly infectious diseases in the world, was a widespread scourge in North America until little more than a century ago. The only people resistant to it were either those of African descent – many of whom had inherited genetic traits that blocked malaria from doing its worst – or folks who had already been infected many times, acquiring resistance the hard way. In general, the more bouts you survive, the more resistant you are.

Mosquito Fact: There would have been no western partition of Africa in the nineteenth century without the discovery of quinine (and development of the machine gun.) No aims w/out means…
Fiction: Remember the collapse of the invaders in ‘War of the Worlds’ They came that close 🙂 but we were saved by some bug.

Here are some interesting points and issues surrounding the ‘tropical disease’ Malaria:
Malaria is thought to have originated in West Africa.

“…..sometimes common throughout Europe as far north as the Baltic and northern Russia.
Transmission was high in many parts of Siberia, and there were 30,000 cases and 10,000 deaths due to falciparum infection (the most deadly malaria parasite) in Archangel, close to the Arctic circle. Malaria persisted in many parts of Europe until the advent of DDT.”
Professor Paul Reiter, Institut Pasteur
See also Malaria in Finland, Russia and Sweden – 1800–1870 [pdf]

————-

“A total of 1,803 persons died of malaria in the western parts of Finland and in the south-western archipelago during the years 1751–1773 [23]. Haartman [21] reports severe epidemics in the region of Turku in the years 1774–1777 and the physician F.W. Radloff mentioned that malaria was very common in the Aland Islands in 1795 [39].”
Huldén et al – 2005 Malaria Journal

————-

“Global warming and malaria: a call for accuracy”
Dr, Prof Paul Reiter et al

————-

“[Canada] But, in the 1800s, particularly along the Rideau and Cataraqui Rivers, malaria was rampant.”
Mysteries of Canada

————-

“Anopheles atroparvus may have maintained malaria endemicity into the present century in certain coastal localities in southern Sweden. ”
Jaenson, Thomas G.T et al – 1986

————-

Malaria was once common in marshland communities in central and southern England between 1500 and 1800, before finally disappearing in the early 1900s [8].”
Steven W Lindsay et al – 2010

————-

“The advent of DDT revolutionized malaria control by targeting the home, leading to widespread eradication of the disease from Europe and North America. By 1975, Europe and North America were entirely free of endemic malaria.”
AEI

————-

“From Shakespeare to Defoe: malaria in England in the Little Ice Age.”
“From 1564 to the 1730s the coldest period of the Little Ice Age malaria was an important cause of illness and death in several parts of England. Transmission began to decline only in the 19th century, when the present warming trend was well under way.”
Centers for Disease Control and Prevention
“The wealth of records in this period confirms that the disease was common at many coastal sites in England and in some parts of Scotland…”

Global warming will have a variety of effects, one of which will probably be the return of indigenous malaria.”

“….there are six records of Eskimos landing their kayaks in Scotland,…”
I have read articles that have claimed that eskimos came to Scotland in their kayaks during the Little Ice Age but I have never been able to find any verifiable evidence to support such claims. If you know of verifiable evidence that eskimos did indeed arrive in Scotland during the LIA then could you please supply it as I would like to pursue it further.

On the subject of nature’s indicators of warmth, or otherwise, Berwick Swans have started to arrive in the UK, 3 weeks earlier than usual, 2 weeks earlier than last year.
If that’s an indicator of the winter to come, I’d better get some more wood cut!

“In order to be fully aware of the evil that can be inflicted by the Scots midge, you’d need to see a caravan or camping park cleared of outside pursuits within minutes of the midge arriving in the early evening. It’s really quite spectacular.”
Indeed I have witnessed such a thing, and been one of the victims who had to take refuge inside a caravan. Those midgies (of whatever origin) are truly evil.
My last Holiday in a bothy on Skye was reduced to only 3 days of outdoor activity. The rest of the Holiday I was cooped up inside for the wee beastly midgies.

On a trip to the high Canadian Arctic in 2000 our party were badly bitten by savage mosquitoes. Fortunately I had a midgie net ( purchased in Scotland ) & my face was protected but the b—–s still managed to get between my gloves & cuffs.
BTW on this trip we visited the remains of a tropical swamp on Axel Heiborg island. Early evidence of Global Warming?

Funny stuff, we can debate how us Americans won independence. It could be the mosquitoes, maybe it was the French and Germans that won it for us. But I believe England’s very own William Pitt the elder who articulated why and how we won our independence.
“If I were an American, as I am an Englishman, while a foreign troop was landed in my country, I never would lay down my arms — never! never! never!”—–William Pitt.

Well, ya, but you guys were the ones the switched up your measurements on us! What the heck? We take the time to learn all of your measurements and distances only for you guys to switch up and tell us we’re doing it wrong. Likely, if we went to driving on the other side you guys would switch back and tell us we’re doing it wrong again! And yeh, we still think you guys are our bestest friends too!

Don’t fall for the “warmer=more malaria” malarky. The mosquito that carries malaria in the northern hemisphere is dependent on human dwellings to prosper. It likes rain barrels and buckets and puddles. It likes to come inside houses. Malaria was common in Siberia until the 1950s or so. Eliminating malaria was not due to draining swamps, but to window screens, elimination of rain barrels, and other hygiene (plus DDT for many decades).

One has only to holiday for a week in the Highlands of Scotland to realise why it is still so empty. No bugger wants to live permanently with those evil Mosquitoes.
The Highlands are beautiful, and I need a good dose of their stunning scenery every couple of years, but live there? No way!

What the scottish midge lacks in stature it makes up for in sheer numbers. I love visiting Scotland but will only go there between Hogmanay (New Year) and the start of May.

As a dumb Engineer, I’d been under the impression that insect-borne diseases required insects and places for them to breed. Mozzies breed around stagnant water. Any liquid water will do. Even for only part of the year. vis Siberia.
Germany’s Emperor Friederich the Great drained the marshlands of what is now central, north-eastern Germany. Fritz wanted arable land to plant potato; but he also got navigable canals for water transport. Serendipitously the drainage diminished the breeding grounds of the pesky insects; which had been spreading various diseases for along time.
Environmentalists seem obsessed with returning nature back to what they dream it was; going mad with artificial “biotopes” featuring stagnant ponds of water. Never mind. Germany has the best (and most expensive) health system in Europe so, with reference to historical records from Charité, they can deal with outbreaks of diseases last recorded scores of years ago.

Yellow fever was feared more than malaria. In summer of 1793 the disease killed 5,000 of Philadlephia’s 45,000 inhabitants and caused some 17,000 to flee the city. http://pds.lib.harvard.edu/pds/view/7374219.
Most don’t realize the Center for Disease Control (CDC) was created to eradicate malaria. Or that 30% of Al Gore’s home state in 1933 were infected with malaria. http://www.cdc.gov/malaria/about/history/#
And it all may be coming back. Recent victories by anti pesticide groups in court now require that the spraying of pesticides over water needs to go through formal permit procedures (9th Circuit ruling?). An impossible task when one is trying to suppress a disease outbreak. Consider a city like Sacramento CA surrounded by hundreds of thousands of acres of rice fields that harbor omnipresent but low levels of malaria, dengue and Japanese encephalitis. The diseases have been kept under control by the judicious use of pesticides-dictated by monitoring programs. Now a point source permit must be applied for and go through hearings to allow for spraying….. Pray for the people in Sacramento and in towns like Key West where Dengue is again rearing its head. (Dengue has no cure and is called bone break fever for a reason)
Its not just the permitting aspects- EPA has had a continuing war on pesticides. Bed Bugs are a good example of how fast things can spin out of control. The explosion of this vermin is the result of EPA banning the pesticides used to control ants and termites in and around homes. DDT knocked them down and the termite and ant treatments allowed til recently suppressed bed bugs as a side effect.
What worries given the above is we may have more to worry about than itching and scratching in this green new world.

“………. the Viking settlements in Iceland and Greenland became extinct ……”
Just for the sake of the record, I had not heard that the Icelanders had become extinct , a typo perhaps ?”
In the light of recent arguments about “plagiarism” I think I need to point out that the statement was a quotation and not my words.
I wrote:
“Paul Reiter’s written presentation to the Select Committee on Economic Affairs covers these matters extensively and is worth reading in its entirety. It can be seen at
http://www.publications.parliament.uk/pa/ld200506/ldselect/ldeconaf/12/12we21.htm
The following is an extract from it.”
And I put the entire matter in quotation marks.
Anyway, Reiter is correct.
He wrote the “Viking settlements in Iceland and Greenland became extinct “. They did.
He did not say “the Icelanders had become extinct”.
A problem with English not being your first langauage, perhaps?

I point out that in the American War of Independence the Americans lost every battle without exception.

I believe that you picked up that mistaken idea from a well-known observation on General Greene’s batting average, boldfaced at the end of this Wikipedia excerpt. He inflicted Pyrrhic victories on his opponents.

http://en.wikipedia.org/wiki/Nathanael_Greene
Nathanael Greene
From Wikipedia, the free encyclopedia
Nathanael Greene (August 7, 1742 – June 19, 1786) was a major general of the Continental Army in the American Revolutionary War. When the war began, Greene was a militia private, the lowest rank possible; he emerged from the war with a reputation as George Washington’s most gifted and dependable officer.
……………..
“The [Southern] army was weak and badly equipped and was opposed by a superior force under Cornwallis. Greene decided to divide his own troops, thus forcing the division of the British as well, and creating the possibility of a strategic interplay of forces. Starting with the success of the great and heroic Battle of Kings Mountain in 1780 under then Colonel William Campbell (he would later be appointed as a Brigadier General in 1781) the entire war changed. The entire British force was captured or killed (100% of all opposing forces) in an unbelievable battle of astounding magnitude. A new strategy led to General Daniel Morgan’s victory of Cowpens on January 17, 1781, where nearly nine-tenths of the entire British force were killed or captured. Many of the same forces who were at King’s Mountain also came to Cowpens.
“With over 800 prisoners Morgan began a strategic retreat, moving north towards Salisbury where he was joined by Greene at Cowan’s Ford on the Catawba River where a force of Patriot Militia fought a small engagement against Cornwallis’s forces. Greene then wrote to Huger to direct his troop movement from Guilford Courthouse. Arriving on February 9 at Guilford, Greene summoned his field officers to a council of war of his chief officers and put forward the question of whether the army should give battle. It was voted that for the time being, the army should continue retreating to gather more forces, and defer engagement with Cornwallis.
…………………..
“”This American retreat, which extended across the breadth of North Carolina, is considered one of the masterful military achievements of all time.” Dennis M. Conrad, Project Director and Editor, The Papers of General Nathanael Greene”
……………………
“Greene’s Southern Campaign showed remarkable strategic features. He excelled in dividing, eluding and tiring his opponent by long marches, and in actual conflict forcing the British to pay heavily for a temporary advantage; a price that they could not afford. However, he was defeated in every pitched battle he fought against the British during his time as southern commander.
“Quotations
• “We fight, get beat, rise, and fight again.”
• “I wish we could sell them another hill at the same price we did Bunker Hill.”
• “Learning is not virtue but the means to bring us an acquaintance with it. Integrity without knowledge is weak and useless, and knowledge without integrity is dangerous and dreadful. Let these be your motives to action through life, the relief of the distressed, the detection of frauds, the defeat of oppression, and diffusion of happiness.”

American General Morgan defeated a British force of regulars under the command of Colonel Tarleton. Morgan's troops enveloped the British in a classic military action that captured all of the British forces.

General Morgan commanded a force of colonialists – "600 Continental soldiers and seasoned Virginia militia men, together with another 500 untrained militia men." Tarleton commanded 1,000 British regulars and lost 910 of them (800 captured) in the battle.

Disease ( sometimes intentionally inflicted ), weather, and terrain have always been major players in warfare, and always will be. Singling out malaria as a major reason why the British lost Yorktown ignores the many other factors leading to that result. There is no single reason why a battle is won or lost – it is always a combination of factors.
