"At the eastern end of the south aisle is a beautiful monument, by [John] Bacon [1740-1799], to Lord Heathfield, the celebrated defender of Gibraltar; it is a mural monument, the basement part of which has a projecting tablet bearing a long inscription which enumerates the achievements of the hero; on the right of it a bas relief of General Elliot, giving his commands to one of his officers, who holds a lighted torch; and on the left, another representing the destruction of the Spanish fleet, one vessel is seen on fire, and a boat's crew endeavouring to save the drowning men from a floating piece of wreck. Over the tablet stands a group consisting of a female figure in a most graceful attitude, representing Britannia, and a boy wearing her helmet and leaning on her shield, with an olive branch in one hand and a key in the other. This beautiful group is finely relieved by a back ground of grey marble, which is again backed by marble of a darker colour. Over them is a medallion head of Lord Heathfield, half encircled with a wreath; on either side of the principal group is a half circular bas relief of a cannon pointed downwards, and the furnace used for heating the shot.
