Here we might leave Duguay-Trouin, for his later services did not greatly concern us. Yet it belongs to our story to record that in the following year he cruised with ten ships, hired by, or belonging to, himself and his brothers. No prize was met, and the expense of keeping so many vessels at sea to no purpose nearly brought the house of Trouin to ruin. This fact in his career supplies an opportunity for summing up the corsair war. It brought him, we see, fame but not profit, and it may be added that this is what it did for France. Looking at it as a whole we note that it gives no support to the often-renewed contention, that attacks by cruisers on sea-borne trade can of themselves bring a maritime power to submission. The work, often tried, has never been better done, and we may feel sure never will be better done than by Duguay-Trouin, and the men he represents here. Yet we see that it did not stop the march of the Grand Fleets of the allies for a day, nor did it ever dam up the main stream of their commerce. Again, the achievements of this famous corsair do by no means prove that single ships, however swift, can destroy commerce. It was while trying to prey on our shipping single-handed that Duguay-Trouin became a prisoner at Plymouth. Precisely the same experience befell Jean Bart, and Forbin at Portsmouth. Their successes were gained in well-appointed squadrons able to meet the shock of battle. The moral of the story is that a maritime power can always defeat the attacks of single ships on its trade by giving convoy. The protecting squadron can only be overpowered by a force like itself, and we come at once to operations of war far beyond the power of the mere corsair or commerce destroyer who relies on his speed only. Success in these operations must finally fall to whichever side possesses the most numerous, and the best-appointed squadrons.
