Every arrangement had been judiciously made. The crew were to be dressed in blue; the password was Britannia, the answer Ireland. The boarders were to take the first spell at the oars; then, as they neared the _Hermione_, they were to be relieved by the regular crews. The expedition was to proceed in two divisions, the one to board on the starboard, the other on the larboard bow, gangway, and quarter. Sharp axes were provided for those who were to cut the bower cable, while others were told off to cut the stern cable, and certain men were to go aloft to loose the sails. In the event of their reaching the ship undiscovered, the boarders only were to board, while the boats' crews were to take the ship in tow directly the cables were cut; but should they be discovered, the crews of each boat were to board and all aid in the enterprise. The rendezvous was to be on the _Hermione's_ quarter-deck. At half-past seven the boats were hoisted out, the crews mustered, and away they pulled from the _Surprise_. As it happened, within a mile of the _Hermione_ the expedition was discovered by two gunboats, and the alarm being given, firing commenced. Captain Hamilton on this pushed for the frigate, believing that all his boats would do the same, but some, misunderstanding his orders, engaged the gunboats. On approaching, lights were seen at every port, with the ship's company at quarters. Captain Hamilton pushed for the bows, and climbing up, his foot slipped and his pistol went off; but he soon succeeded in gaining a footing on the forecastle, and those who had been ordered to loose the sails immediately got the foresail ready for bending and hauling out to the yard-arms, thus forming a screen to themselves, for not a Spaniard was there to interfere with them. On looking down from the forecastle, they saw the crew of the _Hermione_ at quarters on the main-deck, firing away into the darkness, utterly unconscious that the enemy were on board. Captain Hamilton, with the gunner and fourteen men, now made his way to the quarter-deck--part of them, however, under the gunner, being driven back by the Spaniards, who gained possession of the forecastle. Another party of English also neglecting to rendezvous on the quarter-deck, the captain was left for some minutes to defend himself against the attack of four Spaniards, one of whom stunned him, when he fell. Happily, some of his men came to the rescue, and a party of marines climbing over the larboard gangway, now gave a favourable turn to affairs. The rest of the boats coming up, the marines formed, fired a volley, and ran down with fixed bayonets on the main-deck. About sixty Spaniards retreated to the cabin, and surrendered. For some time, however, fighting continued on the main-deck and under the forecastle. The cables were cut, the sails were loosed, while the gunner and two men, though severely wounded, standing at the helm, the boats took the frigate in tow, and she stood out of Puerto Cabello.
