Did Only Six People Really Die in the Great Fire of London?

Last updated 2026-08-23

The Great Fire of London burned for four days in September 1666, destroyed most of the medieval City, and — as almost every retelling adds in the same breath — killed almost nobody, officially just six people. That pairing, a city-levelling disaster with a single-digit body count, is the part that makes people stop and ask if it's really true. We went looking for where "six" comes from, and found that the number people repeat with the most confidence is the one no contemporary document actually states.

The claim

The Great Fire of London (2–6 September 1666) is officially recorded as having killed only a handful of people — most commonly stated as six — despite destroying roughly four-fifths of the walled City and leaving an estimated 70,000–100,000 people homeless.

Source trail

"Six" is the number most retellings settle on, but it isn't the only one in circulation: History.com's own article (checked 2026-08-23) states "official reports listed as few as four people killed," while Wikipedia's own casualties section, drawing on named historians' published work, gives Porter's figure as eight and Tinniswood's as "in single figures" — without landing on a single agreed count. The number's most common home, though, is the fire itself: contemporary accounts are widely described as silent on the subject, with the era's official government newspaper, the London Gazette, reported (via Wikipedia's citation of historian Jacob Field) to have recorded no fatalities at all. On the other side sits historian Neil Hanson, quoted directly on History.com's own page above, arguing the real toll was "several hundred and quite possibly several thousand" once undocumented poor Londoners, deaths from post-fire hunger and exposure, and bodies fully consumed by an unusually hot firestorm are counted. Both the low figure and the high one get repeated as settled fact; neither retelling we found states plainly that the low figure itself isn't settled.

What's confirmed

What isn't

Verdict

The fire really did kill remarkably few people relative to how much of the city it destroyed — every source we could fetch directly agrees the toll was small, whether stated as four, six, eight, or just "single figures." What doesn't hold up is the precision. "Six" is not a figure the fire's own contemporary official record states; two institutions examining that record directly found no death toll in it at all, only later rumor and later historians' separate estimates. The much larger claim — hundreds or thousands — rests on one historian's book-length argument that we could not check against its own source material. Both numbers are repeated far more confidently than either primary source we reached actually supports.

Same shape as our brief on how much the internet weighs: a specific figure gets repeated as settled long after its own trail turns out to be thinner than that.
