Nor was he without good ground for such hope; for Hopson was in great doubt whether it would not be more expedient for him to re-embark. His own health was failing rapidly, and the men were beginning to fall down fast under the incessant work at the advanced posts and the fatigue of carrying provisions to them. From the day of landing it had been found necessary to push these advanced posts farther and farther inland and to make them stronger and stronger, until at last they embraced a circuit of fully three miles. By the end of January the men on the sick list numbered fifteen hundred, or fully a quarter of the force. Hopson sent six hundred invalids to Antigua in the hope of saving at least some of them, but therewith his efforts came to an end, nor could all the representations of Barrington stimulate him to further action. Yet new operations were by no means difficult either of conception or of execution. Guadeloupe is in reality not one island but two, being divided by a narrow strait known as the Salt River. It is very much of the shape of a butterfly with wings outspread, flying south; the western wing being known as Guadeloupe proper and the eastern as Grande Terre, while the Salt River runs in the place of the butterfly's body. Grande Terre, the most fertile part of the island, still lay open to attack, with an excellent harbour at Point à Pitre, of which the principal defence, Fort Louis, could be reached by the cannon of ships. Moore being fortunately independent of Hopson in respect of naval operations, sent ships round to Fort Louis, which speedily battered it into surrender, and installed therein a garrison of three hundred Highlanders and Marines. But even with this new base secured to him Hopson declined to move. He was indeed sick unto death, and on the 27th of February he died, leaving the command to devolve on Barrington.
