The two boats were soon in the water, though the first lieutenant wondered that he had not been sent on this important service. The two officers hurried their crews, and the boats flew on their mission. The commander felt that it was necessary to keep an eye on the fort, for its energetic officer was not at all inclined to be idle at the present exciting time. The Bronx had hardly stopped her screw before the soldiers were to be seen on the barbette; but the shell with which the midship gun had been charged sent them all to the casemates in an instant.

"What is the matter, Captain Passford?" asked the first lieutenant, as he halted on the deck. "You are as pale as a ghost."

"A ball went through my arm; but it is all right," replied Christy with a ghastly smile.

He refused to go below, or to permit Dr. Connelly to come to him until he had attended to the poor fellows who had been wounded on deck.

At the end of a couple of hours, the flames arose from the two bay steamers which had been alongside the Sphinx, for the second lieutenant had been ordered to burn them. The smoke was pouring out of the two smoke-stacks of the steamer. Several boats filled with men pulled to the shore, landing the crews of the three vessels. In less than another hour the Sphinx was under way, and soon came alongside the Bronx.

As only one of the broadsides of the gunboat was available in the action with the fort, the starboard battery was transferred to the captured vessel. Men enough to handle them were put on board, and Mr. Camden was put in command of her. It was late in the afternoon when all this work had been done, and then the Bronx led the way through the Pass, her mission fully accomplished.

As soon as the steamer was abreast of the fort, the broadside guns poured the shrapnel into the embrasures and loopholes, though nothing could be known of the effect of the firing. The muskets were as active as before. Christy was on the bridge still, for the doctor had dressed his wound, and he had taken some refreshment.

This time it was discovered that the vigorous commander of the garrison had dug out some rifle-pits on the top of his works, and his men were doing effective work with their muskets. Three men had been wounded on the deck of the Bronx, the third lieutenant being one of them. Christy shouted to Mr. Flint, ordering him to send the men below, and cease the use of the broadside guns, for the garrison were on the barbette, sheltered by their earth-works, where the guns could not reach them, so high was their position.

With the aid of his speaking trumpet he gave the same order to Mr. Camden on board of the Sphinx; but he had hardly uttered the command before his left leg gave way under him, and he sunk to the floor of the bridge. A ball had struck him in the thigh, and he could feel the blood flowing down his limb. He grasped the rail of the bridge, and drew himself up. There he stood like a statue, supporting himself with his well arm, till the Bronx had passed out of musket-shot range.

"Good heavens!" exclaimed the first lieutenant, as he came out from his shelter. "You are wounded again!"
