Accordingly, on the 15th of July, 1797, his lordship detached upon that service a squadron of three sail-of-the-line, the Theseus, Culloden, and Zealous, 74s; the Seahorse, Emerald, and Terpsichore, frigates, the Fox, 10-gun cutter, and a mortar boat. The whole were under the orders of Rear-admiral Nelson, in the Theseus. In about five days the squadron arrived off the island. Every arrangement that sound judgment could devise having been completed, two hundred seamen and marines from each of the line-of-battle ships, and one hundred from each of the three frigates, exclusive of commissioned officers and servants, and a small detachment of Royal artillery, the whole together amounting to about 1050 men, were placed under the command of Captain Trowbridge, of the Culloden. Each captain, under his direction, commanded the detachment of seamen from his own ship; and Captain Thomas Oldfield, of the marines, as senior marine officer, the entire detachment from that corps. On the night of the 20th of July the three frigates, accompanied by the cutter and mortar-boat, and most of the boats of the squadron, stood in close to the land, to debark the shore party. A strong gale in the offing, and a strong current against them, near the shore, prevented them from reaching the intended point of debarkation. At about half-past three on the morning of the 22d the squadron bore up for Santa Cruz, and soon after daylight was joined by the frigates and small craft. The unavoidable appearance of the latter off the coast gave the islanders the very warning it was so desirable, for the success of the expedition, they should not have. A consultation of the principal officers of the squadron now took place, and decided that an attack should be made on the heights immediately over the fort at the northeast part of the bay; and then, from that commanding position, to storm and carry the fort itself. At nine o’clock on the night of the 22d the frigates anchored inshore, off the east end of the town, and landed their men; but the latter finding the heights too strongly guarded to be attempted, re-embarked in the course of the night, without loss. The three line-of-battle ships had meanwhile kept under way, to batter the fort, by way of diversion; but, owing to calms and contrary currents, were unable to approach nearer than three miles. Nelson, not being one to abandon an enterprise until after a stout struggle to accomplish it, resolved to give his seasoned men a chance at the Santa Cruz garrison as soon as possible. On the 24th the 50-gun ship Leander joined the squadron, having been sent to reinforce it, by Lord St. Vincent. Her captain had considerable experience as a cruiser in those parts, and his local knowledge was therefore valuable; while the additional force was very acceptable and added to the hopes of the attacking party.
