War Over Gibraltar? Spanish Threats and Britain’s Post-Brexit Weakness

Between June 1779 and February 1783 British forces in Gibraltar survived an almost unrelenting Franco-Spanish siege, fighting one of the most remarkable defensive actions in early modern history. Given this heroic feat it is perhaps unsurprising that, more than 200 years later, the British government is not willing to give up its Iberian exclave without a fight.

The Great Siege of Gibraltar

Whether it is wise to threaten the claimant Spaniards with war should they attempt to use Gibraltar as a bargaining chip in negotiations over a post-Brexit EU trade deal is somewhat debatable. What is certain, though, is that London is acutely aware of the symbolic importance of their Mediterranean outpost, even if its strategic significance at the gateway to Europe is becoming increasingly irrelevant.

Captured from the Kingdom of Castile during the War of the Spanish Succession in 1704, Gibraltar was formerly ceded to Britain by the Treaty of Utrecht in 1713. Attempts by the Spaniards to recapture the territory in 1727 and then during the siege of 1779-1783 failed, leaving Gibraltar as an important base for the Royal Navy in the Mediterranean.

Spain has never relinquished its claim to Gibraltar, a somewhat hypocritical stance mindful to overlook Madrid’s remaining colonial possessions on the North African coastline at Ceuta and Melilla. Periodic diplomatic spats have led to border closures and delays, often carefully orchestrated by Spanish crossing guards.

Just as Ceuta and Melilla have a centuries-long affinity with their Spanish motherland, Gibraltar remains unapologetically British. Despite their overwhelming preference to remain within the EU, Gibraltarians have no desire to become part of Spain.

There are of course parallels here with the Falkand Islands, over which Britain went to war against Argentina in 1982. That Spain would attempt a brazen assault on Gibraltar comparable to that launched by the Argentinians against the Falklands is unthinkable, their democratic rulers far more encumbered in their actions than the brutal junta in Buenos Aires ever was.

What George Augustus Eliott, commander of the Gibraltar garrison during the siege of 1779-1783, would think of the petty squabbles of today one can only guess at. Probably he would be gratified by continuing British sovereignty over the outpost his men fought so hard to maintain, no doubt more than eager to throw himself back into the fiery cauldron of battle.

Fortunately, despite the crass comments of some naive politicians, such a scenario is more than unlikely. However, the Spanish decision to publicise this potential stumbling block for Britain’s future economic relations with Europe points to the dissatisfaction on the continent surrounding the Brexit verdict.

Britain has often been seen as an outsider in Europe, an aloof power whose imperialistic history has not endeared it to many of the nations that remain tightly ensconced in the grip of Brussels.

Undoubtedly further tribulations await Theresa May and her Conservative government. Britain’s European neighbours are likely to resurrect these historical enmities in a vindictive attempt to punish one whose dismantling of the long fought for European federalist project is most unwelcome.

As the British and the Spanish have long recognised, the power of a rock cannot be measured by conventional indicators. History, nationalism and symbolism combine to make the most toxic of concoctions.
