Wikipedia Overview

Bardengesang auf Gibraltar: O Calpe! Dir donnert's am Fuße is an fragment of an art song for voice and piano composed by Wolfgang Amadeus Mozart in 1782. It was created to celebrate the British Royal Navy's successful relief of the besieged garrison of Gibraltar in October 1782 during the Great Siege of Gibraltar. A British fleet had evaded a joint Franco-Spanish force to deliver supplies and reinforcements to the garrison before returning home safely – an achievement that was widely lauded and soon forced France and Spain to give up the siege. Mozart's reaction to the British victory was to declare to his father that he considered himself an "arch-Englishman". This was an unusually political outburst from someone who was ordinarily very apolitical, perhaps reflecting antipathy towards the French. He was commissioned to set to music a "bardic song" by Michael Denis celebrating the British success but gave up after only completing three stanzas. In a letter to his father sent at the end of December 1782, he complained of the poet's "exaggerated and bombastic" style.
