At Whitepark in County Wexford, the Ordnance Survey cartographers of 1839 marked a spot as 'Entrenchment (site of)', an acknowledgement, even then, that the earthworks in question were already gone. What appears on that earlier map is a small rectangular field or paddock, roughly 35 metres north-west to south-east and 25 metres across, which is thought to represent a quarry that had already consumed whatever earthen fortifications once stood there.

The earthworks themselves were associated with two distinct periods of conflict. Samuel Lewis, writing in 1837, connected them with the Cromwellian era, when field fortifications, typically low banks and ditches thrown up quickly to defend or besiege a position, were a routine feature of the military landscape across Ireland. They were also thought to have been occupied by British soldiers during the 1798 rebellion, that brief and bloody uprising when County Wexford became one of the principal theatres of fighting. Whether the same earthworks served both purposes across a century and a half, or whether Lewis was simply recording a local tradition by the time he wrote, is not clear. What is certain is that by the time the OS surveyors arrived, the physical evidence had already been quarried away, and by the time the revised six-inch edition appeared in 1940, even the label had shifted to the past tense.

Today there is nothing visible at ground level. The site survives only as a cartographic footnote, a small rectangle on an old map pointing to a place where soldiers once dug into the Wexford soil and where, later, someone dug it out again for stone.
