In July, Brigadier-General Prevost arrived in England, when the government of Dominica was immediately offered to him by Lord Hobart. Having accepted the appointment, he embarked for that island in the following November, and landed there on the 25th of December, 1802. In the following year, he volunteered his services on the expedition against St. Lucie and Tobago, and served as second in command under Lieutenant-General Grenfield, who in his general order, after the capture of Morne Fortunée, thus mentions his conduct upon that occasion:-- "To the cool and determined conduct of Brigadier-general Prevost and Brigadier-General Brereton, who led the two columns of attack, may be attributed the success of the action; but to Brigadier-General Prevost it must be acknowledged, that to his counsel and arrangements the Commander of the forces attributes the glory of the day."[8] The important services of Brigadier-General Prevost upon this expedition, received numerous tributes of approbation from distinguished military characters;[9] and even the French Commander could not refrain from expressing the esteem and admiration with which he regarded his generous enemy.[10] Upon the successful termination of this affair, Brigadier-General Prevost returned to his Government at Dominica, where nothing worthy of notice occurred until the 22d February, 1805, when an unexpected attack was made by a French squadron from Rochefort. The result of that attack was highly creditable to the valour and military talents of the Governor, who after having, with the few troops under his command, disputed inch by inch the landing of the French force, amounting to 4,000 men, and covered by an overwhelming fire from the ships, succeeded in effecting a retreat to the fort of Prince Rupert. The French Commander in Chief, after vainly summoning him to surrender, reimbarked the whole of his troops, and sailed to Guadaloupe.[11] The terms in which H. R. H. the Commander in Chief was pleased to express his sense of General Prevost's conduct upon this occasion, were highly gratifying to his feelings.[12] In consequence of his gallant and successful defence of the Colony, General Prevost received a communication from the Speaker of the House of Assembly,[13] conveying to him the thanks of that body, and informing him that a Thousand Guineas had been voted by them for the purchase of a sword and a service of plate, to be presented to him in testimony of their gratitude and approbation.[14] A similar testimonial to the conduct of General Prevost upon this occasion was given by the Patriotic Fund, who voted him a sword of the value of one hundred pounds, and a piece of plate, of the value of two hundred pounds, "for the distinguished gallantry and military talents which he had displayed."[15] From the West India Planters and Merchants General Prevost likewise received a piece of plate to the value of three hundred guineas.[16]
