Christy was especially warned that the principal business of his expedition was to obtain information in regard to the Trafalgar, though it was probable that a new name had been given to her for the service in which she was to be engaged. The examination of the surroundings of the fort, the captain strongly impressed upon his mind, was entirely subsidiary to the discovery of the intending blockade-runner. In fact, the commander seemed to have serious doubts as to whether it was proper for him even to reconnoitre without special orders for the use of the army. It was several months that Christy had been on board of the Bellevite in his present capacity, and he had become very well acquainted with all the petty officers and seamen of the ship's company, now composed of one hundred and twenty men. After he had finished his supper he walked about the spar-deck to refresh his memory by a sight at all of the men, and selected those who were to take part in his enterprise. One of the first persons he encountered in his promenade was the third assistant engineer, Charles Graines, whom he had known as a boy, before the war. He was not only a machinist, but a sailor, having served in both capacities, though now only twenty-five years of age. Through his father Christy had procured his appointment as an engineer, and his assignment to the Bellevite. The young man was exceedingly grateful to him for this service, and entirely devoted to him. Paul Vapoor, the chief engineer, spoke of Graines in the highest terms, not only in his official capacity, but as a high-toned, patriotic, and thoroughly reliable man. The moment the executive officer put his eye on the assistant engineer, he decided that Graines should be his right-hand man. As a matter of precaution the proposed expedition was to be a profound secret, for there were white men and negroes about the deck who had been picked up in various ways, and were retained till they could be disposed of. They could not be trusted, and doubtless some of them were Confederates at heart, if not engaged in secret missions. Christy invited Graines to the ward room for a conference. There were several officers there, and they retired to the stateroom of the first lieutenant, which is the forward one on the starboard side. The plan, as it had been matured in the mind of the one appointed to carry it out, was fully explained, and the engineer was delighted to be chosen to take part in its execution. The selection of the seamen to compose the expedition was not an easy matter, though every sailor on board would have volunteered for such duty if the opportunity had been presented to him.
