Deletion of Willis' Cave

Comment: The first source is an apparently unpublished, unattributed hand-drawn diagram. The second source doesn't mention the cave, simply referring to "a cave" near Willis' Battery. This fails  so a redirect is not appropriate

Comment: Fails . Searched for "Willis' Cave", Gibraltar in Google Scholar and Google Books and found nothing for it. Both JSTOR and GEOREF also yielded nothing. Found nothing for Willis' Cave while looking through pertinent chapters in Rose, E.P. and Rosenbaum, M.S., 1991. A field guide to the geology of Gibraltar. Gibraltar Museum under the auspices of the Gibraltar Heritage Trust. Finally, according to https://gibraltar-intro.blogspot.com/2019/12/2019-200-caves-of-gibraltar-part-13.html 2019 - The 200 Caves of Gibraltar - Part 13, which itself is a self-published blog, the map (first source) used in the article for the cave's name and location is ''undated and unattributed'' and cannot be considered a reliable source as previously noted
