In ten minutes more the Bronx quivered under the discharge of the great midship gun, and a cloud of smoke rose above her deck.

"Good for you, Mr. Ambleton!" exclaimed Christy, a few seconds later, when he saw the wreck of one of the twenty-four pounders on the fort.

This result was followed by emphatic cheers from the forty-five men on deck.

"I can do that again, Captain Passford," replied the gunner, who was in charge of the piece.

"Do it, then," added Christy.

He did not do quite as well every time, but in two hours there was not a gun in place on the barbette of the fort.

[CHAPTER XXXI]

A WOUNDED COMMANDER

The fort had become harmless so far as the use of its guns was concerned; but the channel of the Grand Pass was hardly a quarter of a mile in width, and even twenty soldiers with muskets could pick off the men on the deck of the Bronx. Christy's orders required him to capture the steamer that was fitting out in the bay, and he intended to do it. The order to weigh the anchor and cast off the spring was given, and the commander sent for the chief engineer.

"We are within a mile of the fort, Mr. Sampson, and I mean to run by it. We shall be exposed to the fire of musketry for about half a mile, and the quicker we make this distance, the less the danger to the men," said the commander, when the engineer presented himself. "We will not get under way till you have all the steam you need to give the steamer her best speed."
