According to the pre-vetted locations, Gibraltar is located "at the southern tip of the Iberian Peninsula and surrounded on three sides by the Mediterranean Sea." "Gibraltar was ceded to Britain under the Treaty of Utrecht in 1713 and remains a British Overseas Territory. It became an important base for the British Royal Navy in the nineteenth century and remained significant during the Second World War as a means to control the entrance to the Mediterranean." Due to its location, Gibraltar would obviously be important to the Navy men and the British government due to its pivotal location in the Mediterranean. Can you please add a few sentences to articulate the connection of Gibraltar to the novel Persuasion and its characters, explicitly? Thank you.
