When he was coming into the bay, Roc had noticed a large French vessel that was lying at some distance from the town, and he wrote his letter as if it had come from the captain of this ship. In the character of this French captain he addressed his letter to the Governor of the town, and in it he stated that he had understood that certain Companions of the Coast, for whom he had great sympathy,—for the French and the buccaneers were always good friends,—had been captured by the Governor, who, he heard, had threatened to execute them. Then the French captain, by the hand of Roc, went on to say that if any harm should come to these brave men, who had been taken and imprisoned when they were doing no harm to anybody, he would swear, in his most solemn manner, that never, for the rest of his life, would he give quarter to any Spaniard who might fall into his hands, and he, moreover, threatened that any kind of vengeance which should become possible for the buccaneers and French united, to inflict upon the Spanish ships, or upon the town of Campeachy, should be taken as soon as possible after he should hear of any injury that might be inflicted upon the unfortunate men who were then lying imprisoned in the fortress.
When the slave came back to Roc, the letter was given to him with very particular directions as to what he was to do with it. He was to disguise himself as much as possible, so that he should not be recognized by the people of the place, and then in the night he was to make his way out of the town, and early in the morning he was to return as if he had been walking along the shore of the harbor, when he was to state that he had been put on shore from the French vessel in the offing, with a letter which he was to present to the Governor.
The slave performed his part of the business very well. The next day, wet and bedraggled, from making his way through the weeds and mud of the coast, he presented himself at the fortress with his letter, and when he was allowed to take it to the Governor, no one suspected that he was a person employed about the place. Having fulfilled his mission, he departed, and when seen again he was the same servant whose business it was to carry food to the prisoners.
