Yellow fever would not be scientifically linked to mosquitoes until the late 19th century.
The Caribbean campaigns of the War of Jenkins’ Ear exposed British troops to lethal tropical diseases. Yellow fever and malaria spread rapidly in crowded ships and encampments. At Cartagena de Indias, thousands of British soldiers fell ill within weeks. Mortality rates soared, with disease claiming far more lives than combat. Medical understanding of mosquito-borne transmission did not exist in the 18th century. Commanders struggled to maintain operational strength as regiments collapsed. The human toll reached into the thousands during a single campaign season.

The disproportionate death toll undermined British morale and logistical capacity. Ships returned to Britain with crews drastically reduced. The scale of disease-driven loss challenged assumptions about naval dominance. Military planners had underestimated environmental risk on a massive scale. The embarrassment lay in failing to anticipate invisible biological threats.
The campaign foreshadowed later imperial struggles with tropical disease across Africa and Asia. It demonstrated that ecosystems could be as decisive as armies. The war’s outcome was shaped not just by strategy but by microbes. An imperial power discovered that climate could nullify cannon.
