Immediately on his rejoining the fleet, he was despatched to the Mediterranean with a small squadron, in order to ascertain, if possible, the object of the great expedition which at that time was fitting out under Buonaparte at Toulon. The defeat of this armament, whatever might be its destination, was deemed by the British government an object paramount to every other; and Earl St. Vincent was directed, if he thought it necessary, to take his whole force into the Mediterranean, to relinquish, for that purpose, the blockade of the Spanish fleet, as a thing of inferior moment; but if he should deem a detachment sufficient, "I think it almost necessary," said the first lord of the Admiralty in his secret instructions, "to suggest to you the propriety of putting it under Sir Horatio Nelson." It is to the honour of Earl St. Vincent that he had already made the same choice. This appointment to a service in which so much honour might be acquired, gave great offence to the senior admirals of the fleet. Sir William Parker, who was a very excellent naval officer, and as gallant a man as any in the navy, and Sir John Orde, who on all occasions of service had acquitted himself with great honour, each wrote to Lord Spencer, complaining that so marked a preference should have been given to a junior of the same fleet. This resentment is what most men in a like case would feel; and if the preference thus given to Nelson had not originated in a clear perception that (as his friend Collingwood said of him a little while before) his spirit was equal to all undertakings, and his resources fitted to all occasions, an injustice would have been done to them by his appointment. But if the service were conducted with undeviating respect to seniority, the naval and military character would soon be brought down to the dead level of mediocrity.
