After forcing the outer defenses, the British re-embarked the landing force to enter the harbor, spending more of the time the defenders needed. The casualty figures are approximate: around 400 killed, including about 122 from enemy action and 250 from yellow fever and malaria, with another 600 sick and hospitalized. Those figures do not reconcile exactly with the running total given in the discussion. Combined with the 3,300 Americans transferred to ships, the losses and sickness had removed more than a third of the army's intended strength before the main assault. Troops still serving afloat and men lost to illness or fighting contributed to that reduction in different ways.

Disease consumes the force before San Lázaro
Re-embarkation, combat losses, yellow fever, and malaria left the landing force badly reduced before it faced Cartagena's main fortifications.
