Lord Hood, never on good terms with General Dundas, now brought matters to a head by sending a somewhat extraordinary letter, in which he said that upon the evacuation of Toulon the General's command had practically ended, and that he (Lord Hood) was in supreme command of both the fleet and the army. The General replied with calmness that, unless the Admiral could produce his commission from the King, neither he nor his officers would acknowledge his pretensions to the command of the land forces. But Lord Hood's letter probably had the result which he desired, for on the following day General Dundas, on the grounds of ill health, gave up the command, and having appointed the next senior officer, Colonel D'Aubant, a brigadier-general, and given him the temporary command of the army, left for England on the 11th March. D'Aubant proved himself a useless commander, and being averse to an assault on Bastia, threw cold water on every plan laid before him. In vain did Lord Hood urge the necessity for an attempt being made by the land forces; and, after holding several councils of war, he at length declared that he would take Bastia with the marines[18] and sailors. Already a month had been wasted in looking at the place--a month which gave the enemy leisure to perfect his fortifications and entrenchments. Almost another month passed before Bastia fell; and its fall was brought about not by assault or bombardment, but by starvation, resulting from Lord Hood's careful blockade from the sea and the Corsicans' watchfulness on land. There had been practically no fighting, and though Hood and Nelson dignified the operations with the name of siege, the army was never in position, and all that was undertaken by the ships was the maintenance of a strict blockade, and the landing of some guns and a fighting force under Nelson. The guns did little damage to the enemy or his works, thus wasting much valuable ammunition, and the force commanded by Nelson (consisting of 1183 soldiers acting as marines on board ship and 250 sailors) made no advance. On the 19th May Bastia was starved into surrender, and the 3500 men of the garrison gave up their arms to the British combined forces, which numbered no more than 3000 soldiers and sailors.
