Cowey Sale is the long riverside meadow just upstream of Walton Bridge, and it carries one of the town’s oldest and most persistent stories: that Julius Caesar forded the Thames here during his second invasion of Britain in 54 BC. The tradition is old, the evidence is thin, and the honest version of the story is more interesting than the confident one.
The claim
The name “Cowey Stakes” refers to a set of wooden stakes once said to have been driven into the riverbed at this crossing point. The tradition holds that these stakes were part of a defensive line, placed to obstruct a river crossing by an invading army, and that the crossing in question was Caesar’s own advance into the territory of the Catuvellauni in 54 BC. Caesar’s own account of the invasion, in his Commentarii de Bello Gallico, describes an opposed river crossing defended by sharpened stakes, both underwater and on the bank. Antiquarians looking for a Thames-side location to match that description settled on Walton.
Camden and the antiquarians
The identification of Cowey Stakes with Caesar’s crossing is generally traced to the Elizabethan antiquarian William Camden, whose survey of Britain, Britannia, first published in 1586, proposed Walton as the likely site. Camden’s reputation as a serious scholar gave the claim staying power, and later writers repeated and elaborated it rather than testing it. By the eighteenth century the identification was treated by many as settled local fact, the kind of claim that gets carved into guidebooks and never quite re-examined.
The stakes pulled from the river
The most concrete part of the story concerns stakes actually removed from the riverbed. Eighteenth-century accounts describe a fisherman pulling up timber stakes from the ford, described as roughly thigh-width, about six feet long, blackened and hardened enough to turn the edge of an axe, and shod with iron at the tip. These were reportedly sold to John Montagu, 5th Earl of Sandwich, at half a guinea apiece. It is a vivid detail, and it is exactly the kind of detail that is easy to report and hard to verify two and a half centuries later. Iron-shod timber stakes in a riverbed could have a dozen explanations that have nothing to do with 54 BC: fish weirs, mill structures, jetties and ford markers were common on the Thames for most of its working history.
What Elmbridge Museum says
Elmbridge Museum, whose job is precisely to weigh claims like this one against the evidence, is careful on the point: it notes that the case for Cowey Stakes as Caesar’s crossing rests on conflicting pre-twentieth-century secondary sources, not on independent archaeological confirmation. In other words, everything written about the stakes descends from a small number of early modern accounts that do not entirely agree with each other, rather than from a body of evidence that has been tested and corroborated since. That is not the same as saying the tradition is false. It is saying that it remains a tradition, however old and however local, and should be presented as one.
We think that is the right way to tell the story. Cowey Stakes is a genuinely good piece of local folklore with a real antiquarian pedigree, and it does not need to be dressed up as settled history to be worth telling. The honesty is, if anything, the more interesting version.
Visiting Cowey Sale today
None of this affects what makes Cowey Sale worth visiting now. It is Walton’s principal riverside open space, a broad meadow running along the Thames immediately upstream of Walton Bridge, with direct access to the Thames Path towpath and space to simply watch the river. It is the natural starting point for riverside walks in both directions, and one of the best places in the town to see rowing crews on the water. Whatever did or did not happen here in 54 BC, it remains one of Walton’s best pieces of open ground, and a fitting place to stand and think about how long people have been crossing the river at this exact point.
