General Butler chose to go in command of the expedition himself, and was all ready to sail by the 9th of December (1864). Very heavy storms prevailed, however, at that time along that part of the sea-coast, and prevented him from getting off until the 13th or 14th. His advance arrived off Fort Fisher on the 15th. The naval force had been already assembled, or was assembling, but they were obliged to run into Beaufort for munitions, coal, etc.; then, too, the powder-boat was not yet fully prepared. The fleet was ready to proceed on the 18th; but Butler, who had remained outside from the 15th up to that time, now found himself out of coal, fresh water, etc., and had to put into Beaufort to replenish. Another storm overtook him, and several days more were lost before the army and navy were both ready at the same time to co-operate.

On the night of the 23d the powder-boat was towed in by a gunboat as near to the fort as it was safe to run. She was then propelled by her own machinery to within about five hundred yards of the shore. There the clockwork, which was to explode her within a certain length of time, was set and she was abandoned. Everybody left, and even the vessels put out to sea to prevent the effect of the explosion upon them. At two o'clock in the morning the explosion took place--and produced no more effect on the fort, or anything else on land, than the bursting of a boiler anywhere on the Atlantic Ocean would have done. Indeed when the troops in Fort Fisher heard the explosion they supposed it was the bursting of a boiler in one of the Yankee gunboats.
