It is easy for Americans to forget that after the intervention of France, the Revolutionary War became a world war. One of the notable events of this global conflict was the siege of Gibraltar by French and Spanish forces from June 24, 1779 to February 7, 1783. The siege was conducted on land and sea with British fleets twice battling through with relief forces and supplies for the Rock. The British garrison, immensely outnumbered, beat off every assault and staged surprise night sorties to keep their foes off balance. The siege was lifted as negotiations over a preliminary peace was underway. The siege was the longest one in British military history. Mozart wrote Bardengesang auf Gibraltar: O Calpe! Dir donnert’s am Fuße to commemorate the British victory.
