GENERAL PRESCOTT ENTERS FORT MATILDA, WHICH IS INVESTED BY THE FRENCH ... SIR JOHN VAUGHAN AND ADMIRAL CALDWELL ARRIVE IN THE WEST INDIES ... SIR CHARLES GREY AND SIR JOHN JERVIS RESIGN THEIR COMMAND, AND RETURN TO EUROPE. Sir Charles Grey, after giving the necessary orders for erecting batteries to protect and secure the camp on Basse Terre, sailed with the Admiral to Martinique, and established his head-quarters at St. Pierre;[61] having previously distributed the troops (which were not left under General Graham on Basse Terre) throughout the islands, where the Brigands began to be very troublesome; and even at Martinique, where the Commander in Chief resided, they had the audacity to shew themselves, encouraged by the sickness which raged in all quarters, and daily weakened our posts. At Grande Rivere and Calabass they appeared in some force; on which the Commander in Chief detached Captain Hare, at the head of a detachment of the Prince of Wales's light[62] dragoons, with Lieutenant Colonel De Soter and the island rangers, who attacked and routed them, taking three of their leaders prisoners, and dispersing the rest. At Guadaloupe no time was lost by Brigadier General Graham in preparing both for attack and defence; he erected gun and mortar batteries upon the banks of the river Sallée, in the different situations where it was most likely the enemy might attempt to cross it from Grande Terre; namely, at the gabarre or ferry, which heretofore was the point of communication between the two parts of the island; at Morne Savon and at St. Jean, both commanding the town of Point à Pitre and Morne Government. By these precautions the Commander in Chief hoped to prevent the enemy from crossing into Basse Terre till he could get a reinforcement from England, which he had expected for some time, and had now dispatched Brigadier General Francis Dundas to explain to government the absolute necessity there was for a supply of troops in the conquered islands. The head-quarters of the army in Guadaloupe were at Camp Berville, a very commanding ground, flanked by the sea on one side, and on the other by an impassable swamp and wood; about a league in front was the river Sallée, on the opposite banks of which stood the town of Point à Pitre; and at the rear, about a mile from the camp, was a narrow pass, by which alone it could be approached. The batteries under the direction of Captain De Rivigne, destroyed a great part of the town, so that the inhabitants were obliged to evacuate it, and encamp on the adjacent hills. The baneful effects of the climate, together with the neighbouring swamps, began now to be severely felt by our army, the officers and men died daily in numbers, and by the middle of August the list of sick and convalescents composed by far the majority in the camp.
