Elliot was made a Knight of the Bath and was created 1st Baron Heathfield of Gibraltar. Many British regiments engaged in the defence were given the badge of the Castle of Gibraltar with the motto "Montis Insignia Calpe," in commemoration of the gallant part they took in the "Great Siege." The failure of the floating batteries reduced General d'Arçon to despair, and he was deeply resentful of the failure for the rest of his life, printing a vindication in 1783 under the title "Mémoires pour servir à l'histoire du siège de Gibraltar, par l'auteur des batteries flottantes."
