It appears on the first edition of the Ordnance Survey six-inch map without any antiquarian marker, the cartographers noting the name plainly, as though it were simply a geographical fact rather than a trace of something violent. The name stuck through to the 1905 edition, quietly preserving the outline of an episode that most histories of the period pass over entirely.

The story behind the name comes from Charles Smith's 1892 work on the county, which records that in 1649 a party of Parliamentary forces erected a battery in that field, directing it against the castle opposite. A battery, in this context, was an emplacement for artillery, a prepared position from which cannon could be trained on a fortification during a siege. The castle at that moment was being defended by the lady of Lord Roche, who held out for several days, in Smith's phrase, "in a gallant manner." This places the site within the broader Cromwellian campaign to reduce Royalist and Catholic resistance across Munster in the years following the execution of Charles I. The Roche family were one of the old Anglo-Norman dynasties of Cork, and the image of a noblewoman directing a defence against Parliamentary artillery is one that deserves more than a footnote. The field name is the only physical residue of that standoff still visible in the landscape, and even that is a matter of cartographic inference rather than confirmed archaeology.
