Early in the year 1780, five hundred men destined for this service were convoyed by Nelson from Port Royal to Cape Gracias a Dios, in Honduras. Not a native was to be seen when they landed: they had been taught that the English came with no other intent than that of enslaving them, and sending them to Jamaica. After a while, however, one of them ventured down, confiding in his knowledge of one of the party; and by his means the neighbouring tribes were conciliated with presents, and brought in. The troops were encamped on a swampy and unwholesome plain, where they were joined by a party of the 79th regiment from Black River, who were already in a deplorable state of sickness. Having remained here a month, they proceeded, anchoring frequently, along the Mosquito shore, to collect their Indian allies, who were to furnish proper boats for the river, and to accompany them. They reached the river San Juan, March 24th; and here, according to his orders, Nelson's services were to terminate; but not a man in the expedition had ever been up the river, or knew the distance of any fortification from its mouth; and he not being one who would turn back when so much was to be done, resolved to carry the soldiers up. About two hundred, therefore, were embarked in the Mosquito shore craft and in two of the HINCHINBROOK's boats, and they began their voyage. It was the latter end of the dry season, the worst time for such an expedition; the river was consequently low.
Indians were sent forward through narrow channels between shoals and sandbanks, and the men were frequently obliged to quit the boats and exert their utmost strength to drag or thrust them along. This labour continued for several days; when they came into deeper water, they had then currents and rapids to contend with, which would have been insur-mountable but for the skill of the Indians in such difficulties. The brunt of the labour was borne by them and by the sailors--men never accustomed to stand aloof when any exertion of strength or hardihood is required. The soldiers, less accustomed to rely upon themselves, were of little use. But all equally endured the violent heat of the sun, rendered more intense by being reflected from the white shoals; while the high woods, on both sides of the river, were frequently so close as to prevent any refreshing circulation of air; and during the night all were equally exposed to the heavy and unwholesome dews.
On the 9th of April they reached an island in the river, called San Bartolomeo, which the Spaniards had fortified, as an outpost, with a small semicircular battery, mounting nine or ten swivels, and manned with sixteen or eighteen men. It commanded the river in a rapid and difficult part of the navigation. Nelson, at the head of a few of his seamen, leaped upon the beach. The ground upon which he sprung was so muddy that he had some difficulty in extricating himself, and lost his shoes: bare-footed, however, he advanced, and, in his own phrase, BOARDED THE BATTERY. In this resolute attempt he was bravely supported by Despard, at that time a captain in the army, afterward unhappily executed for his schemes of revolutionary treason. The castle of San Tuan is situated about 16 miles higher up; the stores and ammunition, however, were landed a few miles below the castle, and the men had to march through woods almost impassable. One of the men was bitten under the eye by a snake which darted upon him from the bough of a tree. He was unable to proceed from the violence of the pain; and when, after a short while, some of his comrades were sent back to assist him, he was dead, and the body already putrid. Nelson himself narrowly escaped a similar fate. He had ordered his hammock to be slung under some trees, being excessively fatigued, and was sleeping, when a monitory lizard passed across his face. The Indians happily observed the reptile; and knowing what it indicated, awoke him. He started up, and found one of the deadliest serpents of the country coiled up at his feet. He suffered from poison of another kind; for drinking at a spring in which some boughs of the manchineel had been thrown, the effects were so severe as, in the opinion of some of his friends, to inflict a lasting injury upon his constitution.
The castle of San Juan is 32 miles below the point where the river issues from the Lake of Nicaragua, and 69 from its mouth. Boats reach the sea from thence in a day and a-half; but their navigation back, even when unladen, is the labour of nine days. The English appeared before it on the 11th, two days after they had taken San Bartolomeo. Nelson's advice was, that it should instantly be carried by assault; but Nelson was not the commander; and it was thought proper to observe all the formalities of a siege. Ten days were wasted before this could be commenced. It was a work more of fatigue than of danger; but fatigue was more to be dreaded than the enemy; the rains set in; and could the garrison have held out a little longer, diseases would have rid them of their invaders. Even the Indians sunk under it, the victims of unusual exertion, and of their own excesses. The place surrendered on the 24th.
