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.

We would have got away with it, if it weren`t for those meddling mozzies!
You may have won independence, but our climatologists are way more incompetent than yours, so there.

The troublesome farmers in the American colonies were left to their own devices, due to the Indian sub-continent being a far more profitable proposition…
“No taxation without representation”?
Huh!
The colonists paid just 1/20th of what the folks back home were taxed at.

“Entomology is the study of insects. Bet these “scientists” could teach us all a thing or two about climate. Hummmm… are you maybe thinking what I’m thinking? Has anyone seen any entomology papers on climate? Hello…! Anyone know an entomologist?”
========================================================
Its just another group of scientists I deem unworthy of the name. Have they said anything? I’ve seen one paper from an infectious disease doctor throughout the whole malaria scare. Perhaps there were other papers, but surely one could have picked up the phone and told a reporter that the scare was BS……….haven’t heard peep out of them. They’re silence was deafening, also.

Not really surprising – before the invention of penicillin (etc) and the understanding of how diseases are contracted (i.e. tainted water – not miasma) casualties in virtually all wars caused by disease greatly out numbered those caused by actual warfare – sometimes by up to 10 to 1.

Thank you ladies and gentlemen for some most informative and amusing posts. I shall continue to drink gin and tonic regularly as a sovereign remedy for all ills. The quinine prevents malaria, the lemon stops scurvy and the juniper is a general antiseptic (but not anti-sceptic).
Chin, chin!

I was laying on a Cot in Ft. Yukon, with the mosquitoes buzzing-round the net(s)
Overheard this conversation: “Shall we take him home or, eat him here? ”
the other Mosquito said:” Better have him here, if we take him home the big ones will get him!”

As one British soldier lamented: “We get terrible provisions now …. putrid meat and wormy biscuits spoiled on the ships. Many of the men have taken sick with the bloody flux and diarrhoea. Foul fever is spreading and we get little rest, night and day”.
I can’t help but add, however, the fact that at the end, with only 3275 fit for duty (out of 4300 British, 2100 German and 1000 American loyalists), facing 3500 CA, 2000 VA Militia, 9500 French ashore with heavy guns and siege engineers, plus 25000 more in the fleet, might have had something to do with the outcome.
P.S. Captain Ludwig, Baron von Closen, observed that a quarter of the Continentals were African Americans [primarily because of the common practice of sending slaves “in lieu” to do the fighting]. The all-black Rhode Island Regiment he described as “the most neatly dressed, the best under arms and the most precise in manoeuvres”.

So here we have yet another professor (it would appear) that has “discipline-ites”(a shallow thinking condition brought on by being cloistered within one’s own discipline), as well pointed out above and as evidenced by one of the final conclusions- Mosquitoes helped the Americans snatch victory from the jaws of stalemate and win the Revolutionary War, without which there would be no United States of America. Obviously, the writer knows little about war, how an army functions and strategic logistical planning. And, in many ways, you can say the same thing for the British at that point in time. They alone put themselves in a position that was unwinnable. Of course, it always the loser that says the winner was “lucky” or had some quirk of fate that help them succeed. To conclude the Americans would not have succeeded at a latter point in time is __________. (Fill at will)

Noted in passing, apparently John Adams contracted malaria in the Netherlands when he went there to try and raise money for the revolution.

Sorry, should have tagged this one along on the other. Dr. Benjamin Rush (signer of the Declaration of Independence) noted in his book Bilious Remitting Fever written in 1793 about the yellow fever epidemic in Philadelphia, that yellow fever had spread as far north as Boston. [His cure of preference was to first purge the patient with mercury salts and then bleed them. I suppose if you survived that, you would survive anything.]

I seem to remember that malaria (Leishmaniasis) from sand flea bites caused more casualties (or deaths) to US troops then combat in the first Iraq War.

Malaria and Dengue disappeared from Peru, South America, in the 1960’s, but “thanks to the GOOD PEOPLE” of the Club of Rome, Malthusians, and the like, DDT was forbidden and these illnesses have came back. Though it is a known fact that the World Health Organization lifted this ban, it seems that many governments still keep the prohibition of its use except for “industrial purposes”.
If the ideologists “free thinkers”, win this war against humanity, that “survival” will not be called the “survival of the more fitted” but the “survival of the unfitted”.

“You were doing fine on your own until you suddenly decided to start driving on the wrong side of the road! ”
It is quite logical and correct to drive on the right side of the road rather than the left.
Since the majority of people are right handed, it is much better that one should have the dominant hand on the wheel while waving the other out the window giving the finger to all other “bad” drivers.

It may have warmed up by October of 1781, but the winters of 1777/78 at Valley Forge and the even colder winter of 1779/80 at Morristown (NJ) seemed to typify the conditions of the ‘Little Ice Age’.
Doesn’t this article show that there can be warm times in an otherwise very cold period?

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!

Anyone who has experienced the voracious clouds of biting ‘midges’ in the Scottish Highlands and wears a kilt, immediately understands the origins the ‘highland fling’.

Oh where are Jefferson’s thermometers now? He kept such good temperature records, including the urban heat island in Philadelphia during the writing of the Declaration. (he moved to the outskirts of town to escape the heat of the city)

From John Cleese :
John Cleese Letter to USA
To the citizens of the United States of America, in the light of your failure to elect a competent President of the USA and thus to govern yourselves, we hereby give notice of the revocation of your independence, effective today.
Her Sovereign Majesty Queen Elizabeth II will resume monarchical duties over all states, commonwealths and other territories. Except Utah, which she does not fancy. Your new prime minister (The Right Honourable Tony Blair, MP for the 97.85% of you who have until now been unaware that there is a world outside your borders) will appoint a minister for America without the need for further elections. Congress and the Senate will be disbanded. A questionnaire will be circulated next year to determine whether any of you noticed. To aid in the transition to a British Crown Dependency, the following rules are introduced with immediate effect:
1. You should look up revocation in the Oxford English Dictionary. Then look up aluminium. Check the pronunciation guide. You will be amazed at just how wrongly you have been pronouncing it. The letter ‘U’ will be reinstated in words such as ‘favour’ and ‘neighbour’, skipping the letter ‘U’ is nothing more than laziness on your part. Likewise, you will learn to spell ‘doughnut’ without skipping half the letters. You will end your love affair with the letter ‘Z’ (pronounced ‘zed’ not ‘zee’) and the suffix ize will be replaced by the suffix ise. You will learn that the suffix ‘burgh’ is pronounced ‘burra’ e.g. Edinburgh. You are welcome to respell Pittsburgh as ‘Pittsberg’ if you can’t cope with correct pronunciation.
Generally, you should raise your vocabulary to acceptable levels. Look up vocabulary. Using the same twenty seven words interspersed with filler noises such as “like” and “you know” is an unacceptable and inefficient form of communication. Look up interspersed. There will be no more ‘bleeps’ in the Jerry Springer show. If you’re not old enough to cope with bad language then you shouldn’t have chat shows. When you learn to develop your vocabulary then you won’t have to use bad language as often.
2. There is no such thing as “US English”. We will let Microsoft know on your behalf. The Microsoft spell-checker will be adjusted to take account of the reinstated letter ‘u’ and the elimination of -ize.
3. You should learn to distinguish the English and Australian accents. It really isn’t that hard. English accents are not limited to cockney,upper-class twit or Mancunian (Daphne in Frasier). You will also have to learn how to understand regional accents – Scottish dramas such as Taggart will no longer be broadcast with subtitles. While we’re talking about regions, you must learn that there is no such place as Devonshire in England. The name of the county is Devon. If you persist in calling it Devonshire, all American States will become shires e.g. Texasshire, Floridashire, Louisianashire.
4. Hollywood will be required occasionally to cast English actors as the good guys. Hollywood will be required to cast English actors to play English characters. British sit-coms such as Men Behaving Badly or Red Dwarf will not be re-cast and watered down for a wishy-washy American audience who can’t cope with the humour of occasional political incorrectness.
5. You should relearn your original national anthem, God Save The Queen but only after fully carrying out task 1. We would not want you to get confused and give up half way through.
6. You should stop playing American football. There is only one kind of football. What you refer to as American football is not a very good game. The 2.15% of you who are aware that there is a world outside your borders may have noticed that no one else plays American football. You will no longer be allowed to play it, and should instead play proper football. Initially, it would be best if you played with the girls. It is a difficult game. Those of you brave enough will, in time, be allowed to play rugby (which is similar to American “football”, but does not involve stopping for a rest every twenty seconds or wearing full kevlar body armour like nancies). We are hoping to get together at least a US Rugby sevens side by 2005. You should stop playing baseball. It is not reasonable to host an event called the ‘World Series’ for a game which is not played outside of America. Since only 2.15% of you are aware that there is a world beyond your borders,your error is understandable. Instead of baseball, you will be allowed to play a girls’ game called rounders, which is baseball without fancy team strip, oversized gloves, collector cards or hotdogs.
7. You will no longer be allowed to own or carry guns. You will no longer be allowed to own or carry anything more dangerous in public than a vegetable peeler. Because we don’t believe you are sensible enough to handle potentially dangerous items, you will require a permit if you wish to carry a vegetable peeler in public.
8. July 4th is no longer a public holiday. November 2nd will be a new national holiday, but only in England. It will be called Indecisive Day.
9. All American cars are hereby banned. They are crap and it is for your own good. When we show you German cars, you will understand what we mean. All road intersections will be replaced with roundabouts. You will start driving on the left with immediate effect. At the same time,you will go metric with immediate effect and conversion tables. Roundabouts and metrication will help you understand the British sense of humour.
10. You will learn to make real chips. Those things you call French fries are not real chips. Fries aren’t even French, they are Belgian though 97.85% of you (including the guy who discovered fries while in Europe) are not aware of a country called Belgium. Those things you insist on calling potato chips are properly called crisps. Real chips are thick cut and fried in animal fat. The traditional accompaniment to chips is beer which should be served warm and flat. Waitresses will be trained to be more aggressive with customers.
11. As a sign of penance 5 grams of sea salt per cup will be added to all tea made within the Commonwealth of Massachusetts, this quantity to be doubled for tea made within the city of Boston itself.
12. The cold tasteless stuff you insist on calling beer is not actually beer at all, it is lager. From November 1st only proper British Bitter will be referred to as beer,and European brews of known and accepted provenance will be referred to as Lager. The substances formerly known as American Beer will henceforth be referred to as Near-Frozen Knat’s Urine,with the exception of the product of the American Budweiser company whose product will be referred to as Weak Near-Frozen Knat’s Urine. This will allow true Budweiser (as manufactured for the last 1000 years in Pilsen,Czech Republic) to be sold without risk of confusion.
13. From November 10th the UK will harmonise petrol (or Gasoline, as you will be permitted to keep calling it until April 1st 2005) prices with the former USA. The UK will harmonise its prices to those of the former USA and the Former USA will, in return, adopt UK petrol prices (roughly $6/US gallon- get used to it).
14. You will learn to resolve personal issues without using guns, lawyers or therapists. The fact that you need so many lawyers and therapists shows that you’re not adult enough to be independent. Guns should only be handled by adults. If you’re not adult enough to sort things out without suing someone or speaking to a therapist then you’re not grown up enough to handle a gun.
15. Please tell us who killed JFK. It’s been driving us crazy.
16. Tax collectors from Her Majesty’s Government will be with you shortly to ensure the acquisition of all revenues due (backdated to 1776).
Thank you for your co-operation and have a great day.

I was taught, at Medical School, that the last “home grow” death from Malaria was in the Fenlands in 1926.
Can’t find an exact reference but for epidemiologist may find the link interesting.
