Rodney made the destruction of the enemy's fleet his first aim. There was only one way of accomplishing it. That was by deserting the old system of fighting in line, van to van, centre to centre, rear to rear. He sighted Guichen's fleet on April 16 as it was sailing northwards and well to leeward of Dominica. Guichen was convoying merchantmen, and intended ultimately to attack Barbadoes. The two fleets were nearly of equal strength. Rodney gained the windward position, and engaged the next morning. He planned to bring the whole of his force to bear on the French centre and rear. After much manoeuvring the opportunity came. Unfortunately his captains, accustomed to the old routine, did not understand his signal. His well-devised plan was defeated and the battle was as inconclusive as its predecessors. Rodney was bitterly disappointed, for a decisive victory seemed within his grasp.[144] He considered that some of his captains did not behave with sufficient promptitude and set himself to bring his fleet to a high pitch of efficiency. Guichen was joined by a Spanish fleet which gave him a great numerical superiority. It was no profit to him; the Spanish ships were hot-beds of disease and he had to convoy them to San Domingo. Then he sailed off for France with the larger part of his force. By that time the hurricane season was at hand and Rodney divided his fleet, leaving about half in the West Indies, and sailing with the remainder to New York, where he arrived on September 12. England had full command of the sea in the American waters, and Rodney did little there and, unfortunately, as we shall see in our next chapter, less than he might have done. At New York his squadron escaped the hurricane which swept over the West Indies on October 10. As Rodney was a tory his distinguished services were peculiarly gratifying to the king and the government. He was created a Knight of the Bath and received a pension with remainder to his children.
