A few days previous to the dispersion of the camp, the Duke of Richmond ordered another selection of four non-commissioned officers and ninety-eight artificers and labourers, to be made from the English companies to reinforce the corps in Flanders; and in order that the party should be formed of the most efficient men, his Grace desired as many as could be spared to be taken for the service from the Brighton detachment. To press as lightly as possible upon individual interests, volunteering was freely allowed, and the remainder were obtained by casting lots. The companies at Woolwich, Portsmouth, and Gosport, were also required to provide their quota; and being collected at head-quarters, they sailed late in August, and in a few days arrived at Ostend. With this reinforcement, the military artificers in the Low Countries amounted to 7 non-commissioned officers, 41 artificers, 104 labourers, and 1 drummer; total 153. Immediately on landing, they were marched to join the company then before Dunkirk, and were employed in the operations for the reduction of that fortress until the 7th of September, when the Duke of York was compelled to abandon his position. On returning to the Artillery Park, the artificers exerted themselves in spiking all the guns that could not be carried with the army and in disabling their carriages, as well as in throwing about 500 barrels of gunpowder into the river and destroying nearly all the intrenching tools. In this siege, three artificers were killed—privates William Drummond, John Fairbairn, and John Wilson; and one was missing—private Thomas Howell; but of the number wounded, no record can be found. Colonel Moncrief, the chief engineer, was dangerously wounded in repulsing a sortie by the enemy on the 6th of September, and died a few days after at Ostend, where he was interred under the flagstaff by some of his own company. A portion of the corps was employed in October in the defence of Nieuport, but in what manner cannot now be ascertained. Indeed, from the paucity of information, either verbal or documentary, rendering it impracticable to trace, with anything like distinctness, the services and movements of the military artificers during the remainder of this and the subsequent campaigns in the Low Countries, unsatisfactory gaps will necessarily appear in this narrative at times, when the most interesting details might have been expected.
