On the afternoon of July 6, 1944, the big top of the Ringling Bros. and Barnum and Bailey Circus caught fire in Hartford, Connecticut, with several thousand people inside, most of them women and children. The canvas had been waterproofed with paraffin thinned in gasoline. The tent burned and came down within minutes while steel animal chutes stood across two of the exits. This guide covers the fabric, the layout, the chutes, the identification work at the State Armory and the tent rules that followed. It also covers the two things the record still does not settle, which are the exact death toll and the cause.

July 6, 1944: an afternoon show and flame on the sidewall

The circus had set up on a lot off Barbour Street in the north end of Hartford. July 6 was a weekday in the middle of the Second World War, and the afternoon audience was heavily weighted toward mothers, grandmothers and children because so many men were in the service or at work in war industry. Estimates of the crowd commonly run from about 6,000 to about 8,000. I have not seen an attendance count I would treat as authoritative, so I give the range and not a number.

Accounts generally put the first sighting of flame at around 2:40 in the afternoon. They place it low on the canvas sidewall near the main entrance, at a time when the Great Wallendas were on or preparing for the high wire. Witnesses described a small patch of fire that some circus workers and spectators tried to put out. Bandleader Merle Evans had the band switch to “The Stars and Stripes Forever,” which circus people used as a signal that something had gone badly wrong, and he kept the band playing while the tent burned. The flame climbed the sidewall and reached the roof. From there it spread across the canvas far faster than anyone in the seats could have expected from what they had seen at the bottom of the wall.

Survivors described burning material falling from the roof onto the crowd and the stands as people tried to get out. Most accounts say the big top collapsed within roughly ten minutes of the first flame, and some put it at less than that. The burning canvas and the poles and rigging that held it up came down on the people still inside. Many people escaped by lifting or cutting through the sidewalls or by jumping from the backs of the seating. The people who died were largely those caught where the exits were obstructed, where the crowd piled up, or under the roof when it fell.

That timeline matters more than any other fact in this guide, because it sets the time available for escape. A routine exit from a circus tent at the end of a show takes many minutes and nobody minds. In Hartford the burning roof set the clock, and the clock ran out before the exits could empty the tent.

Paraffin in gasoline: how the waterproofing became the fuel

A traveling big top of that era was a cotton canvas tent that had to survive rain on the road and on the lot, night after night, across a long touring season. A common way to make canvas shed water was to coat it with paraffin wax. Wax will not soak into heavy canvas as a solid, so it was dissolved in a solvent, painted or sprayed on, and left so the solvent could evaporate and leave the wax in the weave. Most accounts of Hartford say the Ringling big top had been treated this way with paraffin dissolved in gasoline, and some accounts mention other petroleum thinners. Published accounts give specific quantities of wax and gasoline. I have not traced those figures to a primary record, so I leave them out and would send readers to the Connecticut State Library’s circus fire collection for the investigation material.

The fire behavior follows from the materials. Cotton canvas burns on its own. Paraffin is a hydrocarbon, so a wax-loaded canvas carries a substantial added fuel load spread evenly over an enormous surface. Wax also melts as it heats, which is why survivors described flaming drops and pieces falling from the roof. A fire that reaches a vertical canvas wall climbs it quickly, because the flame preheats the fabric above it. Once it reached the roof, it had a continuous, overhead, wax-treated sheet to run across, with the audience underneath it receiving the radiant heat and the falling material. Whether any meaningful amount of gasoline remained in the canvas on July 6 is a point I am not going to assert. The wax alone explains a great deal of what witnesses described.

The treatment was chosen to solve a weather problem, and as far as the record shows, nobody making that choice weighed it as a fire problem. Flame-resistant treatments for fabric existed in the 1940s. Accounts commonly say such treatments were restricted to military use during the war and that this is why the circus did not use them. That explanation is repeated widely. I have not seen it documented in a primary source, so I report it as what accounts say rather than as established fact.

The big top layout: raised seating, a main entrance and a crowd

A big top of the period was an elongated tent with a row of rings and stages down its long axis and a hippodrome track around them for parades and riding acts. Seating ran along both long sides. Reserved chairs sat on raised platforms toward the middle, and the cheaper general admission bleachers, which circus people called the blues, were toward the ends. The audience came in through a main entrance at one end. Other openings existed around the tent, and the sidewalls were staked canvas panels that could in principle be lifted. I am describing the general arrangement of a big top of that era here and not a measured plan of the Hartford tent. The investigation files and the published histories include diagrams, and anyone who needs exact positions should work from those.

The egress problem had two parts. The first was that the exits were sized and arranged for normal operation, in which the crowd leaves over a comfortable period after the finale and staff guide people toward the main entrance. Most of the audience had come in through that entrance and would instinctively try to leave through it. The fire was near it. The second part was the raised seating. People in the upper rows of the stands had to come down to ground level before they could reach any exit, and stairs or aisles off the stands became choke points. Survivors described people dropping or jumping from the back of the seating to the ground outside the stands, which got some out and injured others.

Sidewalls that can be lifted or cut are a kind of exit, and accounts of Hartford make clear that many people got out that way. That kind of exit depends on someone knowing it is possible, having a knife or the strength to raise a staked panel, and doing it while the crowd pushes from behind. It does not show up as a counted, marked, unobstructed opening, and it gives a child or an elderly grandmother nothing to work with. Modern tent provisions require counted exits with real widths, and they do not credit the sidewall as a fallback.

The interaction between the layout and the fire is what made the tent lethal. A fire near the main entrance removed the exit people knew best. The wax-treated roof shortened the time available to minutes. A seating plan built for sightlines put a large part of the crowd above ground level, and that crowd had to come down before it could go anywhere.

The animal chutes: steel runways across the exits

Wild animal acts in the big top used a steel arena cage set up in a ring and a chute, a caged runway, to move the cats between their wagons outside the tent and the arena inside. Accounts of Hartford agree that a wild animal act had performed shortly before the fire and that the chutes were still in place when the fire started. They describe the chutes running across exits, so that people fleeing toward those openings met a barrier of steel bars. Adults had to climb over it, and children had to be lifted or passed across. I have seen the height of the chutes described in different ways, so I describe the effect witnesses reported rather than a dimension.

The chutes did their worst damage through the crowd behind them. A barrier that one person can climb in a few seconds becomes a pileup when hundreds arrive at it at once, because the people at the front slow down to climb while the people behind keep pushing. Survivor accounts and the published histories describe exactly that, with people falling, being pushed against the bars, and being trapped at the chutes as the roof burned above them. Many of the dead were found in those areas.

For a fire inspector, the chutes are the most transferable lesson of the whole event, because they were a temporary obstruction that existed for only part of the performance. An inspection at setup, before the show, could have found every exit clear. The chutes went into place for one act and were meant to come out later, and the fire arrived during the window when they were still across the path. The same pattern shows up today at fairs and festivals and in large tents, where cable ramps, barricades, staged equipment, vendor carts and production gear go in and out of egress paths as an event runs. An inspection regime that looks only at the empty site checks a configuration the crowd never actually experiences.

The count: 167 in most accounts, and why it is not fully settled

The death toll most widely published for the Hartford circus fire is 167, and that is the number I would use with the qualification that goes with it. Other published accounts give 168 or 169. I have not been able to tie each of the higher figures to a single authoritative publisher, so I report that those counts exist rather than attributing them to a named source. Anyone who needs a figure for a report or a presentation should write “167, the figure most widely cited,” and should note that some accounts give a slightly higher number. A writer who states 167 as though it were beyond question has claimed more certainty than the record carries.

A small spread like this has ordinary causes. Burn victims died over days and weeks in the hospital, and a count closed at one point in time can differ from one closed later. Questions about whether particular remains were counted once or twice can move a total by one. The long dispute over one unidentified child, discussed in the next section, has also kept the identification records in public argument for decades. None of this suggests a large hidden toll. It means that the last digit of the number depends on who counted and when.

The injured are harder to pin down than the dead. Accounts commonly say that hundreds of people were injured, many with serious burns, and that the city’s hospitals took large numbers of casualties within the first hour. Published injury figures vary more widely than the death figures, and I am not choosing one. What the record does support is that the dead and injured were overwhelmingly civilians in the audience. A large share of them were children, which shaped both the identification effort and the public response.

The pattern of death is as instructive as the total. Burns, smoke and the collapse of the roof killed people. So did crushing and trampling at the chutes and the exits, and so did falls from the seating. For a medical planner, that mix means a tent fire casualty load has to be planned as both a burn event and a trauma event, with large numbers of children in both groups.

The State Armory and Little Miss 1565: identification and a contested name

The dead were taken to the State Armory in Hartford, where the bodies were laid out in rows and assigned numbers. Families came through to look for their relatives. Contemporary photographs and later accounts describe parents and spouses walking the rows and identifying people by face where that was still possible. Where it was not, they relied on clothing, jewelry, shoes and other personal effects, with dental and fingerprint evidence used where investigators could obtain it. Severe burns defeated visual recognition in many cases, and children were hardest of all, because young children often have no dental records or fingerprints on file and their clothing is less distinctive. A small number of the dead remained unidentified.

The best known of the unidentified is a girl recorded as body number 1565, who became known as Little Miss 1565. Her face was relatively undamaged, a photograph of her was circulated, and still nobody claimed her. In 1991, Hartford fire investigator Rick Davey concluded after years of work that she was Eleanor Emily Cook, an eight-year-old from Southampton, Massachusetts, whose brother also died in the fire. Connecticut’s chief medical examiner’s office accepted that identification, and the remains were reburied in Massachusetts. Davey and Don Massey later set out the case in their 2001 book A Matter of Degree. Stewart O’Nan, in his 2000 book The Circus Fire, questioned the identification on the evidence, and others have disputed it too. The identification stands as an official conclusion that has been contested, and I am not going to resolve it here.

Hartford shows what visual identification by families costs, both emotionally and in accuracy. Asking parents to walk rows of burned bodies is traumatic. Recognition under those conditions is also unreliable, so a mistaken identification can happen and can harm two families at once. Current mass fatality practice moves the families away from the bodies. It takes antemortem information from relatives at a family assistance center, and it makes identifications by scientific means, chiefly fingerprints, dental comparison and DNA, with the medical examiner or coroner holding the authority. The site’s article on mass fatality management covers that structure, and Hartford is a good case to put in front of anyone who doubts why it exists.

The cause: officially unresolved, a cigarette theory and a recanted confession

The cause of the Hartford circus fire has never been officially established. The original investigation by Connecticut authorities did not settle on a proven ignition source. A carelessly discarded cigarette near the sidewall was the explanation most often suggested at the time, and it remains a common one. Nobody has shown it to be what happened. I treat it as a possibility that fits the location and the time of day, and as no more than that.

The arson theory rests mainly on Robert Dale Segee, who had worked as a laborer with the circus in 1944. In 1950, while in custody in Ohio on unrelated arson matters, he told investigators he had set the Hartford fire. He later recanted. He was never charged in connection with Hartford, and investigators and writers have doubted the confession, partly because of questions about his mental state and the reliability of what he described. A confession that was retracted and never tested in court carries limited weight on its own.

Rick Davey’s later reexamination of the case led him to believe the fire was deliberately set. His view is an experienced investigator’s conclusion, and his book presents it in detail. It is not an official finding, and other people who have studied the record, O’Nan among them, were not persuaded. The honest summary is that the cause is officially undetermined, that an accidental ignition such as a cigarette and a deliberate one both have advocates, and that the evidence available decades later has not settled the question for either side.

For the fire protection lessons, the unresolved cause matters less than it might seem. Whatever lit the sidewall, the deaths came from what happened next, as a small fire on a wax-treated wall reached a wax-treated roof over a crowd whose exits were partly blocked. A tent that resisted flame spread would have given a cigarette or a match far less to work with, and clear exits would have emptied the tent faster under either theory.

Liability and the codes: what changed for tents and temporary structures

Several circus officials were charged with involuntary manslaughter after the fire, and some were convicted. I am not summarizing each individual outcome, because the details vary and the court record is the place to read them. Ringling accepted responsibility for the claims. An arbitration arrangement let the circus keep touring and pay victims and families out of its earnings over the following years. The total paid is commonly reported as close to four million dollars, and that figure should be checked against the Connecticut State Library collection before it goes into anything formal.

Hartford came nineteen months after the Cocoanut Grove nightclub fire in Boston, and fire protection writing routinely cites the two together when explaining the modern rules on interior finish, egress and assembly occupancies. For tents specifically, Hartford is the event most often cited as the reason tent fabric is now regulated for flame resistance. I am not going to claim a direct line from Hartford to any particular code provision, because codes develop through committees, editions and local amendments over decades. The current requirements nonetheless address almost every condition that killed people in that tent.

In the United States today, tents and membrane structures are regulated through whichever fire code a state or locality has adopted, usually the International Fire Code or NFPA 1, together with the NFPA standard that covers grandstands, tents and membrane structures, NFPA 102. Those documents generally require a permit for tents above a size threshold, and that threshold varies by edition and local amendment. They also require the fabric to be flame resistant as demonstrated by a recognized test, typically NFPA 701 for textiles. The usual proof is a label on the fabric or a certificate from the manufacturer or treater, and inspectors expect to see it. The codes also generally require counted exits sized for the occupant load, exit signage, aisles kept clear, no smoking inside, portable extinguishers and separation from other structures, generators and cooking. Many jurisdictions also give the fire official authority to require standby fire personnel for large crowds. The specific numbers and thresholds differ from one adopted edition to another, so verify current requirements with your state fire marshal’s office and the edition your jurisdiction has actually adopted.

Two practical weaknesses persist. Flame-resistant treatments on some fabrics can degrade with weathering, cleaning and age, so a certificate that is accurate for new fabric may not describe a tent after years of use, and the treater’s documentation should state what it covers. The second weakness is the one the chutes exposed, which is that egress conditions change during an event. A permit file that shows a compliant tent and a site plan on paper says nothing about where the barricades and equipment ended up at nine o’clock on the busiest night.

What to do at your agency

• The fire marshal or fire prevention officer pulls the permit files for every tent and membrane structure permitted in the past twelve months and confirms that each file contains a flame-resistance certificate or a recorded label check matching the fabric that was actually installed, and lists any file that lacks one.
• The special events coordinator or fire prevention officer adds a line to the existing special event checklist requiring at least one egress walk during the event itself, at a time when production equipment, barricades or animals are in place, and names the inspector or standby officer responsible for doing it and signing off.
• The EMS logistics officer or the fire department’s supply officer inspects the agency’s own deployable shelters, including rehab, decontamination, command post and mass casualty tents, and records which ones carry a flame-resistance label or certificate, tagging any that cannot be documented until the manufacturer provides proof.
• The emergency manager writes one paragraph into the mass fatality annex of the existing emergency operations plan naming the site where a family assistance center would open and stating that families will give antemortem information there rather than view remains, with the medical examiner or coroner named as the identification authority.
• The communications center supervisor asks the fire marshal for the site plan of each large permitted tent event scheduled this season and enters the event contact and the location of the exits into the CAD premise notes for the event address before opening day.
• The fire marshal adds tent and temporary structure requirements to the agenda of the next regular meeting with the county fair board or the largest local event organizer, and confirms with the state fire marshal’s office which code edition and local amendments currently apply.

Takeaways

• The Ringling big top burned in Hartford on July 6, 1944, during an afternoon performance attended by an estimated 6,000 to 8,000 people, most of them women and children.
• The canvas had been waterproofed with paraffin dissolved in gasoline, according to most accounts, which turned the roof into a continuous overhead fuel that dropped burning material on the crowd and collapsed within roughly ten minutes.
• Steel chutes used to move the cats for a wild animal act were still in place across exits when the fire started, and many of the dead were found where the crowd piled up against them.
• The death toll most widely published is 167, with some accounts giving 168 or 169, so any formal use of the number should say it is the most widely cited figure.
• Families identified many of the dead by walking rows of bodies at the State Armory, and the 1991 identification of Little Miss 1565 as Eleanor Cook was accepted officially and has been publicly disputed since.
• The cause remains officially undetermined, with a discarded cigarette long suggested, a 1950 confession by Robert Segee that he later recanted, and an arson conclusion by investigator Rick Davey that others have not accepted.
• Modern fire codes regulate tents through permits, certified flame-resistant fabric, counted and clear exits and separation distances, and the edition your jurisdiction has adopted determines the specific numbers.
• An egress inspection done only at setup can miss obstructions placed during the event, which is exactly how the Hartford chutes came to be across the exits.
