After eighteen months in this debilitating climate, he became dangerously ill, and was sent home in the Dolphin in 1776. The youth of sixteen became very despondent. "I felt impressed," he says, "with an idea that I should never rise in my profession. My mind was staggered with a view of the difficulties I had to surmount, and the little interest I possessed. I could discover no means of reaching the object of my ambition. After a long and gloomy revery, in which I almost wished myself overboard, a sudden flow of patriotism was kindled within me and presented my king and country as my patrons. My mind exulted in the idea. 'Well, then,' I exclaimed, 'I will be a hero, and, confiding in Providence, I will brave every danger.'" From that time he often told his friend Hardy, "a radiant orb was suspended in his mind's eye, which urged him onward to renown." Captain Suckling had now become comptroller of the navy; and as soon as Nelson was recovered, through his uncle's influence, he was made fourth lieutenant of the Worcester, a ship of sixty-four guns, commanded by Mark Robinson, going out to Gibraltar. At nineteen he passed an excellent examination in naval matters, and was made second lieutenant on the Lowestoffe, of thirty-two guns, under Captain William Locker, then fitting out for the West Indies. The vessel arrived at Carlisle Bay, Barbadoes, July 4, 1777. Nelson soon showed his usual bravery. An American letter-of-marque was captured. The first lieutenant was ordered to board her; but, unable to reach her by reason of the high sea, Nelson volunteered, and though his boat swept over the deck of the American privateer, he finally got aboard, and made her his prize. Soon after Nelson was appointed third lieutenant of the flag-ship Bristol, and in 1779 commander of the Badger, protecting the Mosquito Coast and the Bay of Honduras from the privateers. Many French merchantmen were captured. During these years from 1777 to 1780, the skirmishes with the Spaniards and French, though marked with great energy and bravery on the part of Nelson, were ruinous to him and his men. Hundreds of the latter died from the malaria of the climate, or were poisoned by the bites of serpents. Nelson himself, more dead than alive, was carried back to England, and for many months remained at Bath, endeavoring to regain his health. Fretting at his inactive life, he applied for a position which was not granted for some months; and then he was sent, much against his will, to the bleak North Sea to protect the home trade. Here he spent a winter in discomfort, but he learned many things which were of inestimable value in one of his great battles afterwards.
