Background

Gibraltar is a British territory and mountainous peninsula on the far southern coast of the Iberian peninsula, at one of the narrowest points in the Mediterranean, only from the coast of Morocco in North Africa. It is dominated by the steeply sloping
Rock of Gibraltar
The Rock of Gibraltar (from the Arabic name Jabal Ṭāriq , meaning "Mountain of Tariq ibn Ziyad, Tariq") is a monolithic limestone mountain high dominating the western entrance to the Mediterranean Sea. It is situated near the end of a nar ...
, high. A narrow, low-lying isthmus connects the peninsula to the Spanish mainland. High coastal cliffs and a rocky shoreline make it virtually impossible to attack from the east or south. The west side – occupied by the town of Gibraltar, which stands at the base of the Rock – and the northern approach across the isthmus have been
densely fortified by its various occupants with numerous walls, towers and gun batteries. The geography of the peninsula provides considerable natural defensive advantages, which combined with its location have imbued Gibraltar with enormous military significance over the centuries.
The first documented invasion of Gibraltar was by the

ninth siege took place after Medina Sidonia persuaded Alfonso to grant him the fortress, following which the Duke sent an army to storm the town. Henry's governor held out for fifteen months before finally surrendering in July 1467. Medina Sidonia's grandson, the third duke

again declared Gibraltar crown property in 1501, but her death three years later left Castile in turmoil, prompting Medina Sidonia to take advantage of the kingdom's weakness. He assembled an army and marched on Gibraltar in the hope that the city would simply open its gates to him, but it did not, forcing him to lay siege to it instead; he abandoned the attempt after three months.

Gibraltar lived in relative peace for over 200 years after the tenth siege, by which time the ''Reconquista'' was completed and Spain was unified under a single crown. The Rock's importance as a fortress diminished and its defences were neglected. The next siege came in 1704, during the

It was initially assumed that Britain would not permanently retain Gibraltar, and would eventually trade it for something else, but the strength of British public opinion made it politically impossible to use the territory as a bargaining chip.

thirteenth siege from the isthmus on 22 February, but after four months, the Spanish supply chain could not keep up with the demands of the siege and, lacking a navy, Spain was unable to prevent Britain from resupplying the garrison by sea.
In the years following the thirteenth siege, tensions began to resurface between Britain and France, and Spain remained neutral in a series of wars waged over the two nations' rival ambitions. The Treaty of Utrecht was reaffirmed by a succession of treaties, but Spain remained determined to regain the territory she had lost. In addition to her struggles with France, Britain also struggled with her
