The fevers, which were of the greatest malignity at this time, affected the officers more than the common men. Only one captain died at Jamaica while the fleet was there, and it was of this fever. We lost five lieutenants, of whom four died of it; and this was the disease which carried off the three surgeons. But foul air was not the only cause that produced this fever among the officers, several of whom brought it on by hard drinking, or fatiguing themselves by riding or walking in the heat of the sun. It cannot be too much inculcated to those who visit tropical countries, that exercise in the sun, and intemperance, are most pernicious and fatal practices, and that it is in general by the one or the other that the better sort of people, particularly those newly arrived from Europe, shorten their lives. Before leaving Jamaica, I sent to England a Supplement to the Memorial given in, last year[20]. CHAP. V. Account of the HEALTH of the FLEET, from its leaving Jamaica on the 17th of July, till its Departure from New York on the 25th of October.----What Diseases most prevalent on the Passage to America--Rapid Increase of the Scurvy during the last Week of the Passage--Method of supplying the Sick at New York--The Fleet uncommonly healthy in October--State of the Weather and of Health in America in Summer and Autumn, 1782. The season of the hurricanes approaching, and all the convoys destined for England this year being dispatched, the main body of the fleet, consisting of twenty-four ships of the line, left Port Royal on the 17th of July, under the command of Admiral Pigot, in order to proceed to the coast of America. A great convoy for England had been sent off a few days before, protected by the Ville de Paris and six other ships of the line, which we overtook and passed at the west end of the island. When we arrived off the Havannah, a large squadron of the enemy was seen there in readiness to sail, which induced the Admiral to wait in sight of it for the convoy, which did not come up till ten days after. Owing to this delay, and our meeting with baffling winds on the rest of the passage, we did not arrive at New York till the 7th of September. We found there the Invincible and Warrior, which sailed after us, but arrived before us, by having taken the windward passage.
