offered just the conditions that gave most advantage to an inferior force standing on the defensive. The qualities and characteristics of the enemy are among the principal factors which a man of genius considers, and it was to this as much as to any other one trait that Nelson owed his dazzling successes. On the other hand, the French admiral attacked in a wholly unscientific manner, ship against ship, without an attempt to concentrate on a part of the enemy, or even trying to keep him in play until the French squadron of eight ships-of-the-line in Messina, near by, could join. Such tactics cannot be named beside that of Solebay or the Texel; but as Duquesne was the best French officer of the century, with the possible exception of Tourville, this battle has a value of its own in the history of tactics, and may by no means be omitted. The standing of the commander-in-chief is the warrant that it marks the highest point to which French naval tactics has as yet attained. Before quitting this discussion, it may be noted that the remedy Clerk proposed was to attack the rear ships of the enemy's line, and preferably to leeward; the remainder of the fleet must then either abandon them or stand down for a general action, which according to his postulate was all that the English seamen desired. After the fight De Ruyter sailed to Palermo, one of his ships sinking on the way. Duquesne was joined outside Messina by the French division that had been lying there. The remaining incidents of the Sicilian war are unimportant to the general subject. On the 22d of April, De Ruyter and Duquesne met again off Agosta. Duquesne had twenty-nine ships, the allied Spaniards and Dutch twenty-seven, of which ten were Spanish. Unfortunately the Spaniard commanded in chief, and took the centre of the line with the ships of his country, contrary to the advice of Ruyter, who, knowing how inefficient his allies were, wished to scatter them through the line and so support them better. Ruyter himself took the van, and the allies, having the wind, attacked; but the Spanish centre kept at long cannon range, leaving the brunt of the battle to fall on the Dutch van. The rear, following the commander-in-chief's motions, was also but slightly engaged. In this sorrowful yet still glorious fulfilment of hopeless duty, De Ruyter, who never before in his long career had been struck by an enemy's shot, received a mortal wound. He died a week later at Syracuse, and with him passed away the last hope of resistance on the sea. A month later the Spanish and Dutch fleets were attacked at anchor at Palermo, and many of them destroyed; while a division sent from Holland to reinforce the Mediterranean fleet was met by a French squadron in the Straits of Gibraltar and forced to take refuge in Cadiz.
