Within months the 64th had returned to the West Indies for a campaign of seizing islands held by, variously, France, The Netherlands and Denmark. The first island to fall was the Franco-Dutch island of Saint Martin. This was followed by the Dutch island of St Eustatius and the Danish islands of Saint Thomas, Saint John and Saint Croix. With the signing of the Treaty of Amiens, which restored to France and its allies all territories conquered by the British, the 64th were withdrawn to Barbados. Peace did not last long and in 1803 war with France broke out again. The 64th was immediately in action being part of an expeditionary force that took St Lucia, earning the battle honour "St Lucia 1803" — the award of this honour was more timely, it being awarded in 1818. The expedition continued onto the South American mainland with the capture of Dutch held Surinam in 1804. A fourth battle honour, "Surinam", was awarded — again in 1818. Garrison duties kept the 64th in Surinam for the next nine years meaning that the regiment played no further part in the Napoleonic Wars.
