The officer who brought the order having returned to his vessel, the captain accompanied Frank on deck, and ordered the second cutter to be called away and furnished with a crew well armed. In a short time the boat was ready, and Frank, buckling on his side-arms, took leave of the captain and started toward the flag-ship, wondering what duty he was now called upon to perform, and fully determined that whatever orders he might receive, however dangerous or difficult, should be executed, if within the bounds of possibility.
When he arrived on board the Blackhawk, an officer, who appeared to be waiting for him, conducted him into the cabin, where the admiral sat writing at his desk.
"Good morning, Mr. Nelson," said he; "take a chair, sir."
Frank took the seat pointed out to him, and the admiral, taking from his desk a bundle of papers, carefully tied up, continued:
"It has always been my habit, Mr. Nelson, not to let a brave or skillful action pass unrewarded, any more than I would allow a bad one to pass unpunished. I am now about to give you a much more important, and perhaps dangerous, commission than has yet been intrusted to you. This package contains official documents of the greatest importance, and I want you to go down the river, and deliver it to the commanding naval officer, whom you will find at Acklen's plantation, opposite the mouth of Red River. I know there are rebels all along the banks, but whatever you do, don't allow these letters to fall into their hands. There are iron weights in the package, and if you should be in danger of capture, throw it overboard. You will take passage on the army transport that now lies at the stern of this vessel, all ready to start. I send the cutter and armed crew with you, for the reason that the rebels may sink the transport, in which case you can escape in your boat; for those letters must go through, if possible; perhaps the success of this expedition depends upon them. The transport, you will find, is in command of a second-lieutenant. I should feel much safer if I could put one of my own officers in charge, but, as the boat belongs to the army, I have no authority in the matter. After you have executed your orders, return, by first opportunity, to your vessel, and report to me by letter. Now, sir, you may go, for they are waiting for you. Remember, I say the success or failure of this entire expedition may depend upon you; and don't forget that you are the young man that saved the Milwaukee."
Frank bowed himself out of the cabin, sprang into the cutter, and started toward the transport that lay alongside of the bank, a short distance below the flag-ship. As he stepped on board, he was met by a flashy-looking young lieutenant, dressed in a brand-new uniform, who greeted him with the inquiry:
"Are you ready at last? I have been waiting an hour for you. Business is business, you know, and when I command a ship, I don't like to be detained."
The lieutenant said this, probably, to impress upon Frank's mind the important fact that he was the captain of the steamer, and must be respected and obeyed accordingly. Frank, who knew that he was not subject to the orders of the lieutenant only so far as the safety of the vessel was concerned, replied that he had come as soon as he could after he had received his orders, and turning to his men, directed part of them to make the cutter fast to the stern of the steamer, and the others to carry their arms to the boiler-deck, where they could be readily seized in case of emergency. The transport was a small side-wheel boat belonging to the quarter-master's department. The deck-hands were all soldiers—perhaps half a dozen of them in all—the only steamboatmen on board being one pilot, four engineers, and as many firemen. The steamer was armed with two howitzers, mounted on the boiler-deck, and the muskets of the soldiers were stacked in the cabin. The boilers were protected by bales of cotton, which were piled on the guards, and the pilot-house was defended in the same manner. A few bales were also placed on the boiler-deck to serve as a breastwork. The whole was under the command of the lieutenant, who, judging by the orders he issued, knew nothing whatever of the management of a boat.
Frank had been on board but a few moments, when the engineer's bell rang, to inform the pilot that all was ready for the start. The boat was made fast by a single line, which ran from the forecastle to a tree on the bank, and the gang-plank was out. The lieutenant's first order was, "Haul in that plank." The soldiers obeyed, and then came the command for "somebody to run out there and untie that line."
One of the soldiers sprang ashore and began trying to cast off the line, which was drawn as taut as a four-mile current could make it. He worked for several moments, but, of course without success (for the line should first have been slackened up on board), and then called out:
