Background and detail

Background. The Anglo-Spanish War had previously been fought between 1796 and 1802. The Treaty of Amiens in 1802 established peace between Britain and Spain. However, following the resumption of war between France and Britain in 1803, Anglo-Spanish relations gradually deteriorated. This diplomatic breakdown set the stage for military confrontation in late 1804.

Triggering Incident. On 5 October 1804, the Royal Navy intercepted and defeated a Spanish squadron transporting gold and silver to Cádiz. This engagement, known as the Action of 5 October 1804, significantly escalated tensions. The incident directly led to Spain's formal declaration of war against the United Kingdom in December 1804.
