Consequently the captivity dragged itself wearily out for three years after the order of release was received. The victim chafed, protested, left no stone unturned, but Decaen was not to be moved. Happily depression did not drag illness in its miserable train. "My health sustains itself tolerably well in the midst of all my disappointments," he was able to write to Banks in 1809. CHAPTER 26. THE RELEASE. From June, 1809, the British squadron in the Indian Ocean commenced to blockade Ile-de-France.* (* Flinders to Banks, Historical Records 7 202.) Decaen's fear of Flinders' knowledge is revealed in the fact that he ordered him not for the future to go beyond the lands attached to Madame D'Arifat's habitation. Flinders wrote complying, and henceforth declined invitations beyond the immediate neighbourhood of the plantation. He amused himself by teaching mathematics and the principles of navigation to the two younger sons of the family, and by the study of French literature. After October the blockade increased in strictness, under Commodore Rowley. Decaen's situation was growing desperate. Fortunately for him, the French squadron brought in three prizes in January, 1810, slipping past Rowley's blockade, much to that enterprising officer's annoyance. The situation was temporarily relieved, but the assistance thus afforded was no better than a plaster on a large wound. Here again we find Flinders accurately and fully informed: Decaen did not underrate his "dangerous" potentialities. "The ordinary sources of revenue and emolument were nearly dried up, and to have recourse to the merchants for a loan was impossible, the former bills upon the French treasury, drawn it was said for three millions of livres, remaining in great part unpaid; and to such distress was the Captain-General reduced for ways and means that he had submitted to ask a voluntary contribution in money, wheat, maize, or any kind of produce from the half-ruined colonists. It was even said to have been promised that, if pecuniary succour did not arrive in six months, the Captain-General would retire and leave the inhabitants to govern themselves." Decaen, in fact, saw clearly that the game was up. His threat to retire in six months did not mean that he would not have given the British a fight before he lowered the tricolour. He was not the man to surrender quite tamely; but he knew that he could no longer hold out for more than a measurable period, the length of which would depend upon the enemy's initiative.
