By the 19th century, four sentry boxes (of which only their bases remain) and seven cannon emplacements on the parapets of the battery were remodelled (with the addition of two new gun emplacements to the south and one to the north). At the time of the Peninsular War the post was manned by nine artillery men, a commander and eleven members of the infantry. But, between 1813 and 1814, there was no manned garrison on the site.
