The French Revolutionary Wars of 1793–1802 and the Napoleonic Wars of 1803–15 saw the Royal Navy reach a peak of efficiency, dominating the navies of all Britain's adversaries. Initially Britain did not involve itself in the French Revolution, but in 1793 France declared war, leading to the Glorious First of June battle in the following year off Brest, followed by the capture of French colonies in the Caribbean. The Dutch Republic declared war in 1795 and Spain in 1796, on the side of France. Further action came in 1797 and 1798, with the Battle of Cape St Vincent and the Battle of the Nile (also known as the Battle of Aboukir Bay), which brought Admiral Horatio Nelson to the public's attention. The latter engagement cut off Napoleon's expedition to Egypt, though French forces remained in control of that country for three more years. In 1800 Russia, Sweden and Denmark agreed to resist British warships searching neutral shipping for French goods and in 1801 the Danes closed their ports to British shipping. This caused Britain to attack ships and the fort at the Battle of Copenhagen.
