The Admiral was now busily engaged in working out a plan for employing the troops on the transports in some enterprise which, while redounding to his own credit, would compensate in a measure for the abandonment of the great French arsenal; for he was aware that the evacuation of Toulon without destroying all the French ships, although the only step that, under the circumstances, was possible, might be regarded in England as a grave failure on his part. Something, he decided, must be done at once, and that something must take the form of providing for the British fleet in the Mediterranean a base deeper in than that afforded by Gibraltar, which was at that time the only British possession in the Mediterranean, and almost a thousand miles from Genoa, in the neighbourhood of which port the French and Austrian armies were operating. Lord Hood realised from the outset the broad principle that, as Captain Mahan[15] says, "the policy of Great Britain was to control the sea for the protection of commerce, and to sustain on shore the continental powers in the war against France--chiefly by money, but also by naval co-operation when feasible." Under these circumstances, the Admiral's thoughts naturally turned to Corsica, which, though still garrisoned by French troops, was known to be more or less in revolt against the Republican Government. The exact state of affairs in the island, however, and the strength of the French defences and garrisons, were things about which Lord Hood had little information; and though he regretted the necessity for delaying the capture of Corsica, he wisely accepted, on this occasion, the advice of the military commanders to send two military officers to reconnoitre and report on the practicability of making a descent on the island. Moore and a major of artillery named Koehler were selected for this duty, and on the 11th January (1794) left in the _Lowestoffe_ frigate, in which also sailed Sir Gilbert Elliott, one of the King's Commissioners in the Mediterranean, who was to endeavour to persuade the Corsican inhabitants to assist the British force in ridding the island of the French interlopers.
