British Germ Warfare Against American Indians Documented

This information I had on my now “archived” Operation Morning Star web page…the most read page on the Pine Ridge Indian Reservation.

Jeffrey Amherst and Smallpox Blankets

The documents

These are the pivotal letters:

Several other letters from the summer of 1763 show the smallpox idea was not an anomaly. The letters are filled with comments that indicate a genocidal intent, with phrases such as:

“… every Tree is become an Indian….” Colonel Henry Bouquet to General Amherst, dated 29 June 1763. [63k]

Lord Jeff

Lord Jeffrey1 Amherst was commanding general of British forces in North America during the final battles of the so-called French & Indian war (1754-1763). He won victories against the French to acquire Canada for England and helped make England the world’s chief colonizer at the conclusion of the Seven Years War among the colonial powers (1756-1763).

The town of Amherst, Massachusetts, was named for Lord Jeff even before he became a Lord. Amherst Collegewas later named after the town. It is said the local inhabitants who formed the town preferred another name, Norwottuck, after the Indians whose land it had been; the colonial governor substituted his choice for theirs. Frank Prentice Rand, in his book, The Village of Amherst: A Landmark of Light [Amherst, MA: Amherst Historical Society, 1958], says that at the time of the naming, Amherst was “the most glamorous military hero in the New World. … …the name was so obvious in 1759 as to be almost inevitable.” [p. 15]

The history of the naming of the town of Amherst, New York, shows a similar idolizing of the general:

On April 10, 1818, the Town of Amherst was officially created by an Act of the Senate of the State of New York. This new town was named for Sir Jeffrey Amherst, an English lord who was Commander-in-Chief of the British troops in America in 1758-1763, before the American Revolution. King George III rewarded Lord Amherst by giving him 20,000 acres in New York, but Lord Amherst never visited his new lands. [From: A Brief History of the Town of Amherst, (Amherst Museum, 1997)

Smallpox blankets

Despite his fame, Jeffrey Amherst’s name became tarnished by stories of smallpox-infected blankets used as germ warfare against American Indians. These stories are reported, for example, in Carl Waldman’s Atlas of the North American Indian [NY: Facts on File, 1985]. Waldman writes, in reference to a siege of Fort Pitt (Pittsburgh) by Chief Pontiac’s forces during the summer of 1763:

… Captain Simeon Ecuyer had bought time by sending smallpox-infected blankets and handkerchiefs to the Indians surrounding the fort — an early example of biological warfare — which started an epidemic among them. Amherst himself had encouraged this tactic in a letter to Ecuyer. [p. 108]

Some people have doubted these stories; other people, believing the stories, nevertheless assert that the infected blankets were not intentionally distributed to the Indians, or that Lord Jeff himself is not to blame for the germ warfare tactic.

Lord Jeff’s letters during Pontiac’s Rebellion

The documents provided here are made available to set the record straight. These are images of microfilmed original letters written between General Amherst and his officers and others in his command during the summer of 1763, when the British were fighting what became known as Pontiac’s Rebellion.

Pontiac, an Ottawa chief who had sided with the French, led an uprising against the British after the French surrender in Canada. Indians were angered by Amherst’s refusal to continue the French practice of providing supplies in exchange for Indian friendship and assistance, and by a generally imperious British attitude toward Indians and Indian land. As Waldman puts it:

… Lord Jeffrey Amherst, the British commander-in-chief for America, believed … that the best way to control Indians was through a system of strict regulations and punishment when necessary, not “bribery,” as he called the granting of provisions. [p. 106]

The British Manuscript Project

The documents provided here are among Amherst’s letters and other papers microfilmed as part of the British Manuscript Project, 1941-1945, undertaken by the United States Library of Congress during World War II. The project was designed to preserve British historical documents from possible war damage. There are almost three hundred reels of microfilm on Amherst alone.

The microfilm is difficult to read, and paper copies even harder. Nonetheless, the images obtained by scanning the copies are sufficiently clear for online viewing. The images are of key excerpts from the letters. An index is provided to show by microfilm document number the location of the imaged documents in the microfilm set. Text files of the excerpts are also provided.

The documents

These are the pivotal letters:

These letters also discuss the use of dogs to hunt the Indians, the so-called “Spaniard’s Method,” which Amherst approves in principle, but says he cannot implement because there are not enough dogs. In a letter dated 26 July 1763, Bouquet acknowledges Amherst’s approval [125k] and writes, “all your Directions will be observed.”

Historian Francis Parkman, in his book The Conspiracy of Pontiac and the Indian War after the Conquest of Canada [Boston: Little, Brown, 1886] refers to a postscript in an earlier letter from Amherst to Bouquet wondering whether smallpox could not be spread among the Indians:

Could it not be contrived to send the Small Pox among those disaffected tribes of Indians? We must on this occasion use every stratagem in our power to reduce them. [Vol. II, p. 39 (6th edition)]

I have not found this letter, but there is a letter from Bouquet to Amherst, dated 23 June 1763, [189k] three weeks before the discussion of blankets to the Indians, stating that Captain Ecuyer at Fort Pitt (to which Bouquet would be heading with reinforcements) has reported smallpox in the Fort. This indicates at least that the writers knew the plan could be carried out.

It is curious that the specific plans to spread smallpox were relegated to postscripts. I leave it to the reader to ponder the significance of this.

Several other letters from the summer of 1763 show the smallpox idea was not an anomaly. The letters are filled with comments that indicate a genocidal intent, with phrases such as:

Amherst’s correspondence during this time includes many letters on routine matters, such as officers who are sick or want to be relieved of duty; accounts of provisions on hand, costs for supplies, number of people garrisoned; negotiations with provincial governors (the army is upset with the Pennsylvania assembly, for example, for refusing to draft men for service); and so on. None of these other letters show a deranged mind or an obsession with cruelty. Amherst’s venom was strictly reserved for Indians.

The French and the Indians

The sharpest contrast with letters about Indians is provided by letters regarding the other enemy, the French. Amherst has been at war with the French as much as with the Indians; but he showed no obsessive desire to extirpate them from the earth. They were apparently his “worthy” enemy. It was the Indians who drove him mad. It was they against whom he was looking for “an occasion, to extirpate them root and branch.” [J. C. Long, Lord Jeffrey Amherst: A Soldier of the King (NY: Macmillan, 1933), p. 187]

Long describes Amherst’s “kindliness to the French” and refers to Amherst’s “intensity of feeling on these issues”:

Amherst’s kindliness to the French civilians was more than a military gesture. He had a warm sympathy for the countryside, an interest in people and the way they lived. “The Inhabitants live comfortably,” he observed in his journal, “most have stone houses…. ….

This humane attitude was reflected in his rules for the governing of Canada. As its de facto military Governor-General he established a temporary code … a program of tolerance and regard for colonial sensibilities….


Perhaps most statesmanlike of all was Amherst’s recognition of the French law, … a recognition which permitted change of national loyalty without social upheaval. [p. 137]

In contrast to these kindly feelings, Long says that Pontiac’s attacks on British forts at Detroit and Presqu’Isle “aroused Amherst to a frenzy, a frenzy almost hysterical in its impotence.” Long then quotes from Amherst’s letter to Sir William Johnson:

… it would be happy for the Provinces there was not an Indian settlement within a thousand Miles of them, and when they are properly punished, I care not how soon they move their Habitations, for the Inhabitants of the Woods are the fittest Companions for them, they being more nearly allied to the Brute than to the Human Creation. [p.186]

Colonel Bouquet’s poetic line, “… every Tree is become an Indian,” [63k] quoted above, was his description of a contagion of fear among “the terrified Inhabitants,” for whom the Indians were a part of the wildness they perceived around themselves. Indian warriors would not stand in ordered ranks; they fell back into the forests only to emerge again in renewed attack; their leaders defied British logic and proved effective against a string of British forts; these were the enemy that nearly succeeded in driving the British out, and became the target for British genocide.2


All in all, the letters provided here remove all doubt about the validity of the stories about Lord Jeff and germ warfare. The General’s own letters sustain the stories.

As to whether the plans actually were carried out, Parkman has this to say:

… in the following spring, Gershom Hicks, who had been among the Indians, reported at Fort Pitt that the small-pox had been raging for some time among them….

An additional source of information on the matter is the Journal of William Trent, commander of the local militia of the townspeople of Pittsburgh during Pontiac’s seige of the fort. This Journal has been described as “… the most detailed contemporary account of the anxious days and nights in the beleaguered stronghold.” [Pen Pictures of Early Western Pennsylvania, John W. Harpster, ed. (University of Pittsburgh Press, 1938).]

Trent’s entry for May 24, 1763, includes the following statement:

… we gave them two Blankets and an Handkerchief out of the Small Pox Hospital. I hope it will have the desired effect.

Trent’s Journal confirms that smallpox had broken out in Fort Pitt prior to the correspondence between Bouquet and Amherst, thus making their plans feasible. It also indicates that intentional infection of the Indians with smallpox had been already approved by at least Captain Ecuyer at the fort, who some commentators have suggested was in direct correspondence with General Amherst on this tactic (though I have not yet found such letters).


1. There is some dispute about the spelling of Amherst’s first name. As Lion G. Miles points out, ‘Amherst always signed as “Jeff:” so there has been a long-standing controversy as to the correct spelling of his first name. I am reasonably certain that it should be “Jeffery.” Those officers closest to him, his aides etc., always spelled the name that way and transcribed his orders as from “Jeffery.” Official letters addressed to him from England and the British Army List have it as “Sir Jeffery Amherst” (never mind that Bouquet solved the problem by addressing him as “Jeffry”). Even the biography by Long … has the title of “Lord Jeffery Amherst,” not “Jeffrey.”‘ [Lion G. Miles, member of the board, Native American Institute at Hudson, NY, in a personal email communication, 15 November 1998]

2. The depiction of Indians as wild beasts was quite common among early American leaders, including George Washington and Thomas Jefferson. David E. Stannard writes: ‘As is so often the case, it was New England’s religious elite who made the point more graphically than anyone. Referring to some Indians who had given offense to the colonists, the Reverend Cotton Mather wrote: “Once you have but got the Track of those Ravenous howling Wolves, then pursue them vigourously; Turn not back till they are consumed… Beat them small as the Dust before the Wind.” Lest this be regarded as mere rhetoric, empty of literal intent, consider that another of New England’s most esteemed religious leaders, the Reverend Solomon Stoddard, as late as 1703 formally proposed to the Massachusetts Governor that the colonists be given the financial wherewithal to purchase and train large packs of dogs “to hunt Indians as they do bears.”‘ [American Holocaust: Columbus and the Conquest of the New World (New York & Oxford: Oxford University Press (1992)), p. 241]

Additional Sources of Information

1. Medical information

A mild form of smallpox virus, Variola minor (also called alastrim), is transmitted by inhalation and is communicable for 3-7 days. The more serious smallpox virus, Variola major, is transmitted both by inhalation and by contamination; it is communicable by inhalation for 9-14 days and by contamination for several years in a dried state. For further medical information, see Donald A. Henderson, et al., “Smallpox as a Biological Weapon: Medical and Public Health Management,” Journal of the American Medical Association Vol. 281 No. 22 (June 9, 1999).

Ann F. Ramenofsky, Vectors of Death: The Archaeology of European Contact (Albuquerque, NM: University of New Mexico Press, 1987), also discusses the question of communicability:

Among Class I agents, Variola major holds a unique position. Although the virus is most frequently transmitted through droplet infection, it can survive for a number of years outside human hosts in a dried state (Downie 1967; Upham 1986). As a consequence, Variola major can be transmitted through contaminated articles such as clothing or blankets (Dixon 1962). In the nineteenth century, the U.S. Army sent contaminated blankets to Native Americans, especially Plains groups, to control the Indian problem (Stearn and Stearn 1945). [p. 148]

Abraham B. Bergman, et al., “A Political History of the Indian Health Service,” comments on the birth of the Indian Health Service:

Federal health services for Indians began under War Department auspices in the early 1800’s. At that time the Federal Indian policy was primarily one of military containment. As early as 1802 Army physicians took emergency measures to curb contagious diseases among Indian tribes in the vicinity of military posts. The first large scale smallpox vaccination of Indians was authorized by Congress in 1832, probably launched more to protect US soldiers than to benefit Indians.

2. Social and Political Effects of Disease

E. Wagner Stearn & Allen E. Stearn, The Effect of Smallpox on the Destiny of the Amerindian (Boston: Bruce Humphries (1945)), point out the social-political effects of smallpox:

Smallpox, which was introduced into the mainland of the Americas in the early part of the sixteenth century, not only decimated the native population for four centuries, but so demoralized the tribes through the terror it spread among them that it has been considered by many authorities to have been an important factor in their comparatively easy subjugation by the whites. Before the advent of the white man tribal warfare and, at times, famine made the chief inroads on the native population, but during the period of exploration and settlement the diseases of the white man, new to the native, caused terrific havoc. It is claimed that Haiti (Espanola) alone lost two-thirds of its population in the three years of Columbus’s conquest, during the years 1492-1495. The two to three hundred inhabitants had quickly fallen prey not only to ruthless conquest but to a variety of infectious diseases. [p. 13]

Harold Napoleon, Yuuyaraq: the Way of the Human Being, with commentary, edited by Eric Madsen (Fairbanks, Alaska: University of Alaska, College of Rural Alaska, Center for Cross-Cultural Studies (1991)), states that epidemics caused a form of post-traumatic stress disorder and social collapse:

Compared to the span of life of a culture, the Great Death was instantaneous. The Yup’ik world was turned upside down, literally overnight. Out of the suffering, confusion, desperation, heartbreak, and trauma was born a new generation of Yup’ik people. They were born into shock. They woke to a world in shambles, many of their people and their beliefs strewn around them, dead. In their minds they had been overcome by evil. Their medicines and their medicine men and women had proven useless. Everything they had believed in had failed. Their ancient world had collapsed.

From their innocence and from their inability to understand and dispel the disease, guilt was born into them. They had witnessed mass death—evil—in unimaginable and unacceptable terms. These were the men and women orphaned by the sudden and traumatic death of the culture that had given them birth. They would become the first generation of modern-day Yup’ik. [p. 11]

The survivors taught almost nothing about the old culture to their children. It was as if they were ashamed of it, and this shame they passed on to their children by their silence and by allowing cultural atrocities to be committed against their children. The survivors also gave up all governing power of the villages to the missionaries and school teachers, whoever was most aggressive. There was no one to contest them. In some villages the priest had displaced the angalkuq. In some villages there was theocracy under the benevolent dictatorship of a missionary. The old guardians of Yuuyaraq on the other hand, the angalkuq, if they were still alive, had fallen into disgrace. They had become a source of shame to the village, not only because their medicine and Yuuyaraq had failed, but also because the missionaries now openly accused them of being agents of the devil himself and of having led their people into disaster. [pp. 13-14]

3. Other writers on Amherst and smallpox

A.1. Elizabeth A. Fenn, “Biological Warfare in Eighteenth-Century North America: Beyond Jeffrey Amherst,” Journal of American History vol. 86, no. 4 (March, 2000), pp. 1552-1580:

Our preoccupation with Amherst has kept us from recognizing that accusations of what we now call biological warfare—the military use of smallpox in particular—arose frequently in eighteenth-century America. Native Americans, moreover, were not the only accusers. By the second half of the century, many of the combatants in America’s wars of empire had the knowledge and technology to attempt biological warfare with the smallpox virus. Many also adhered to a code of ethics that did not constrain them from doing so. Seen in this light, the Amherst affair becomes not so much an aberration as part of a larger continuum in which accusations and discussions of biological warfare were common, and actual incidents may have occurred more frequently than scholars have previously acknowledged. [p. 1553]

A.2. Elizabeth A. Fenn expands on this theme in her book, Pox Americana: The Great Smallpox Epidemic of 1775-82 (NY: Hill and Wang, 2001), discussing widespread accusations and examples of biological warfare on the American continent during this period. Selected excerpts from the book are presented on a separate page.

B. Helen Jaskoski, “‘A Terrible Sickness Among Them’: Smallpox Stories of the Frontier,” in Helen Jaskoski, ed., Early Native American Writing: New Critical Essays (Cambridge: Cambridge University Press, 1996), 136-157:

Three nineteenth-century historians who wrote about the colonial Great Lakes area recorded accounts of smallpox epidemics and their origins. The most widely known smallpox story comes from Francis Parkman’s The Conspiracy of Pontiac (1870). Ottawa political leader Andrew J. Blackbird relates a similar story from the same period of the French and Indian War in his History of the Ottawa and Chippewa Indians of Michigan (1887). William Whipple Warren, a Minnesota Ojibwa historian and legislator, offers two very different accounts of an epidemic that took place in Minnesota in the 1780s in his History of the Ojibway People (1885). Comparison of these historians’ smallpox stories enlarges our understanding of the history and epidemiology of the disease in the particular period. The smallpox stories also offer insight into alternative conceptualizations of the experience that historians a century later envisioned as the “frontier.” One other Ojibwa historian, George Copway, who does not tell a smallpox story, offers in his Indian Life and Indian History (1860) such a paradigm for understanding events of the time – including smallpox epidemics – as they were experienced by the native communities. [pp. 137-138]

An excerpt from Blackbird’s History, with Jaskoski’s introduction and commentary, are presented on a separate page.

C. Adrienne Mayor, “The Nessus Shirt in the New World: Smallpox Blankets in History and Legend,” Journal of American Folklore 108(427):54-77 (1995):

One name is repeatedly linked to the story of the smallpox blanket: Jeffrey Amherst. In 1851, Francis Parkman was the first historian to document Lord Amherst’s “shameful plan” to exterminate Indians by giving them smallpox-infected blankets taken from the corpses of British soldiers at Fort Pitt in 1763 (Parkman 1991:646-651). The feasibility of the documented plan, whether or not it was successfully carried out, has given credibility and moral impact to the fears expressed in all poison-garment tales. The Amherst incident itself has taken on legendary overtones as believers and nonbelievers continue to argue over the facts and their interpretation. [p. 57]

D. Robert L. O’Connell, Of Arms and Men: A History of War, Weapons, and Aggression (NY and Oxford: Oxford University Press, 1989):

Marking a milestone of sorts, certain colonists during the French and Indian Wars resorted to trading smallpox-contaminated blankets to local tribes with immediate and devastating results. While infected carcasses had long been catapulted into besieged cities, this seems to be the first time a known weakness in the immunity structure of an adversary population was deliberately exploited with a weapons response. [p. 171]

E. R. G. Robertson, Rotting Face: Smallpox and the American Indian (Caldwell, Idaho: Caxton Press, 2001):

With the surrender of New France to Great Britain, command of the English North American military forces fell to Lord Jeffrey Amherst. An arrogant aristocrat who despised all Indians, Amherst withheld gunpowder and lead from France’s former native allies, stating that England’s enemies ought to be punished, not rewarded. When informed that the tribes depended on their muskets for taking game and would starve without ammunition, he remained unswayed, callously informing his aides that they should seed the complaining bands with smallpox so as to lend starvation a speedy hand. [p. 119; with footnote to Herman J. Viola, After Columbus (Washington: Smithsonian Books, 1990), 98]

In the spring of 1763, during the Indian uprising led by Ottawa Chief Pontiac, a party of Delawares ringed British owned Fort Pitt (now Pittsburgh, Pennsylvania), calling for its surrender. Captain Simeon Ecuyer, a Swiss mercenary and the fort’s senior officer, saved the garrison by giving the Delawares a gift—two blankets and a handkerchief. The Indians readily accepted the offering, but still demanded that Ecuyer vacate the stockade. They had no inkling that the blankets and kerchief were more deadly than a platoon of English sharpshooters. Ecuyer had ordered the presents deliberately infected with smallpox spores at the post hospital. By mid July, the Delawares were dying as though they had been raked by a grape cannonade. Fort Pitt remained firmly in English hands. [with footnote to Robert M. Utley and Wilcomb E. Washburn, Indian Wars (New York: American Heritage, 1977; Boston: Houghton Mifflin, 1987)]

The same year, British General Sir Jeffrey Amherst urged Colonel Henry Bouquet to figure some way of infecting France’s Indian allies with smallpox. On July 13, the colonel wrote that he would attempt seeding some blankets with Variola, then send them to the warring tribes. Recognizing the risk of such a tactic, Bouquet expressed the hope that he would not catch the sickness himself. Whether the plan was ever carried out is unknown. [p. 124; with footnote to John Duffy, “Smallpox and the Indians in the American Colonies,” Bulletin of the History of Medicine 25 (1951): 324-341]

F. Mark Wheelis, “Biological warfare before 1914,” in E. Geissler and J. Moon, Biological and Toxin Weapons: Research, Development and Use from the Middle Ages to 1945 (Oxford: Oxford University Press, 1999), pp. 8-34:

[Historical events and records] suggest that the use of smallpox as a weapon may have been widely entertained by British military commanders, and may have been employed without scruple when opportunity offered, possibly on a number of occasions. [p. 29]
