But though this movement produced the immediate effect which was designed, it led to ill consequences, which Nelson foresaw, but for want of sufficient force was unable to prevent. His squadron was too small for the service which it had to perform. He required two seventy-fours and eight or ten frigates and sloops; but when he demanded this reinforcement, Admiral Hotham had left the command. Sir Hyde Parker had succeeded till the new commander should arrive; and he immediately reduced it to almost nothing, leaving him only one frigate and a brig. This was a fatal error. While the Austrian and Sardinian troops, whether from the imbecility or the treachery of their leaders, remained inactive, the French were preparing for the invasion of Italy. Not many days before Nelson was thus summoned to Genoa, he chased a large convoy into Alassio. Twelve vessels he had formerly destroyed in that port, though 2000 French troops occupied the town. This former attack had made them take new measures of defence; and there were now above 100 sail of victuallers, gun-boats, and ships of war. Nelson represented to the Admiral how important it was to destroy these vessels; and offered, with his squadron of frigates, and the CULLODEN and COURAGEUX, to lead himself in the AGAMEMNON, and take or destroy the whole. The attempt was not permitted; but it was Nelson's belief that, if it had been made, it would have prevented the attack upon the Austrian army, which took place almost immediately afterwards.
