The oiler asked no questions, though he might have been excused for wondering what the young commander intended to do with shot without powder. In a few minutes the shot were in place, as Christy had directed. The midshipman was watching with all his eyes the movement of the enemy, and, as the Bellevite approached the position of the wreck, the boat darted out from the other side of her. It began to be exciting for the middy, loaded with the responsibility of the safety of the steamer, though he seemed to be as cool as Boxie himself, who had seen some sea fights in his day.
Christy leaped on the rail of the ship, where he could obtain a full view of the situation. The boat was approaching with all the speed the oarsmen could command, and they seemed to be experienced hands. There could be no doubt of the intentions of the enemy, and the midshipman drew his heavy naval revolver from his pocket.
"Stand by to repel boarders!" he called to the seamen. "Pass up one of those shot, Sampson. Have a hand mount the rail, each with a shot, at the points where you have placed them."
"The ladies wish to know what is going on, Christy," said Paul, coming from the engine-room.
"I have no time to talk now," replied Christy impatiently, as he saw the approaching boat within ten feet of the side of the steamer. "Tell them to stay where they are, and not come on deck!"
The boat was not a large one, and it did not contain more than a dozen men; but the fine form of Captain Carboneer could be seen, as he stood up in the stern sheets. Those who were not pulling the oars began to discharge revolvers at the men now mounted on the rail; but the motion of the boat and the ship seemed to defeat their aim, and no one was hit so far as was known.
"When the boat comes alongside, let the man who is in the right place for it drop his shot into it. Be careful of it, and don't waste the iron," shouted Christy, when the decisive moment came.
"All ready, sir," responded the men along the rail.
"You are the man, Boxie! You are in the right place for the first shot," added the midshipman.
Boxie was next to him, and it would be Christy's turn next if the old man failed to do good work with his shot. The boat came alongside, and a bowman fastened his boathook at the side of the ship, and held it in place. At the same moment Boxie let drive his sixty-pound shot; but he ought to have waited an instant longer, for the missile dropped harmlessly into the river.
