In the hope of obtaining some advantage to counterbalance this misfortune, the enemy, on the 1st of May, made a brisk attack on the advanced post of grenadiers commanded by Lieutenant-Colonel MacDonald, of the 55th Regiment. They were, however, repulsed with much slaughter, though not till forty or fifty men, and several officers, were killed or wounded on the side of the British, among them being Captain Coghlan, 1st West India Regiment, attached to the 48th Regiment, who was wounded.
At the south side of the Morne Fortune the enemy had erected batteries, which precluded any vessels from entering into the bay of the Grand Cul de Sac. To open this bay to our fleet was an object of much importance, as at present it was necessary to convey the artillery and stores from a great distance, which could not be done without the previous labour of opening roads through an almost impracticable country. It was, therefore, resolved to make an attempt on these batteries. The principal attack was to be conducted by Major-General Morshead, whose division, in two columns, was to pass the river of the Grand Cul de Sac; the columns of the right at Cools, and that of the left at the point where the waters of the stream are discharged into the bay. To second this force, Brigadier-General Hope, on the night of the 2nd of May, was to advance from Morne Chabot with 350 men of the 42nd Regiment, the light company of the 57th, and part of Malcolm's Rangers, the whole being supported by the 55th Regiment, which was posted at Ferrands. A part of the squadron was likewise to lend its assistance, by keeping up a cannonade on the works of the enemy. Before the time arrived for putting this plan into execution, Major-General Morshead was taken ill, and the command devolved upon Brigadier-General Perryn. No change, however, took place in the arrangements which had been formed.
"At dawn of day, the division under Brigadier-General Hope began to accomplish its part of the service by carrying the battery Seche, which was situated within a short distance of the works of Morne Fortune. The assailants suffered so little in the assault, that they would scarcely have had anything to regret, had it not been for the fall of the gallant Lieutenant-Colonel Malcolm.[24] On the south side of the Morne, and at the extremity of the line of attack, Colonel Riddel, who led the column of the left, made himself master of the battery of Chapuis, and established himself there. Had the remainder of the project been as well executed, the proposed object would have been completely attained. Unfortunately, however, from some unexplained cause, the division which was the connecting link of the whole, that which was entrusted to Brigadier-General Perryn, did not perform its allotted part, by crossing the river at Cools. The consequence of this was that the victorious columns were left insulated, and would have been exposed to no trivial danger, had the enemy felt a sufficient reliance upon their own strength to incite them to act with the requisite promptitude and vigour. Painful, therefore, as it was to retire before a routed foe, the British troops were compelled to abandon the batteries which they had won, and to fall back upon their original stations. The ships at the same time returned to their former anchorage. Our loss on this occasion was 105 men; of whom only a very few were among the slain."
