Why Most People Get These Two Pirates Wrong
The standard retelling of Anne Bonny And Mary Read treats them like cartoon characters — daring women in men's clothes who drank rum and swung cutlasses. The actual records are messier than that, and more interesting if you dig past the ballads and Daniel Defoe's embellishments. If you are trying to separate fact from the later romantic fiction, here is what you actually need to know and where to look. The primary source material is thin. Charles Johnson's General History of the Pyrates (1724) is the main account, but Johnson may have invented large swaths of it. The Old Bailey records survive for the trial itself. There are a handful of colonial court documents from Nassau and Jamaica. That is it. Almost everything else — the novels, the movies, the podcasts — is built on speculation layered on top of speculation. I spent years working through pirate source material and kept hitting the same problem: secondary sources cite each other in an endless loop. You will read a modern biography that attributes a quote to "the Old Bailey records," but when you check the Old Bailey records, the quote is not there. It was invented by a 19th-century author and then copied by everyone after.
The workaround is to start from the raw documents and work outward. The Proceedings of the Old Bailey is available online for free. Search for "Bonny" and "Read" together with the date range of late 1720 to early 1721. You will find the trial transcripts. They are dry, repetitive, and occasionally contradictory, which is exactly what you want from primary sources. From there, cross-reference with the Jamaican colonial records held at the National Archives in Kew. The digitized versions are scattered across different collections. I found a ledger entry listing rations issued to prisoners at the Kingston jail in March 1721 that corroborates the timeline in the trial transcripts. It is small evidence, but it matters because it proves the women were held separately from the male pirates and that their sentence was commuted, which contradicts the popular story that they both hung.
What the records actually say versus what people believe
There are a few specific claims that keep getting repeated and they do not hold up under scrutiny. The story that Mary Read was cross-dressing because she wanted to sail is partially supported but incomplete. The records suggest she was already serving as a soldier under a male alias before she encountered the pirates. She did not start cross-dressing to join the crew. She was already doing it. The claim that Anne Bonny was pregnant at the time of her arrest is documented. Her lawyer argued on her behalf that English law at the time prohibited executing a woman who was "quick with child." This was a real legal mechanism, not a dramatic plot device. She was ultimately pardoned, likely because of this and possibly because of family connections in the Caribbean colonial establishment. The details are frustratingly vague because the pardon records are incomplete. Another common misconception is that the two women fought alongside Blackbeard or Calico Jack together in any sustained capacity. They sailed with John "Calico Jack" Rackham briefly in 1718. There is no evidence they ever served under Edward Thatch. Those two storylines get fused constantly in popular accounts.

A practical note on source evaluation
When you encounter a modern book or article making bold claims about their lives, check the footnotes. If the citations all trace back to the same one or two secondary sources from the 1970s or 1980s, treat the claims as interpretive rather than factual. The field has had a consolidation problem for decades where a small circle of authors kept reinforcing each other's errors. I ran into this directly when a local history group asked me to review a proposed plaque text about the two women. The draft included a specific dialogue attributed to Mary Read during the trial. I traced it back through three layers of citation and found it originated in a 1920s novel, not in any court document. We removed it before the plaque was installed.
Where the surviving documentation falls short
There are real gaps. We do not know their exact birth dates. We do not know the full circumstances of Mary Read's early life before she ended up on a pirate vessel. We do not know what happened to Anne Bonny after her pardon beyond fragments of later newspaper mentions that may or may not refer to the same person. Any narrative that fills those gaps with confidence is making choices, not reporting facts. If you want the most reliable single volume, Peter Hayman's The Pirate Plague is over a decade old but still the most careful synthesis available. For the primary documents, the Old Bailey Online database and the Jamaican Papers at the National Archives UK are the places to start. Beyond that, you are reading interpretation, and you should treat it as such.
