Tropical health as an operational advantage

How did the British keep their troops healthier on disease-ridden Guadeloupe?

They enforced hygiene, supplied fresh food and vegetables, provided enough manpower for adequate rest, and removed stagnant water.

Disease was a major threat on the Caribbean station, and the French defenders were already suffering heavily from it. The British force entered the operation comparatively healthy and worked deliberately to preserve that advantage. Fresh food and vegetables, adequate sleep, sufficient troop numbers, and removal of stagnant water were practical health measures. This discipline preserved more of the force for maneuver while illness weakened the French position.
