"It is 'engage the enemy' probably," said his companion. "After we have answered it a few times more, perhaps we will recognize it when we see it."
"If that is what the signal means, why don't you go to your stations?" inquired Marcy, as they began walking leisurely toward the waist to leave the forecastle clear for the blue-jackets, who came forward in obedience to a shrill call from the boatswain's whistle, which was followed by the command: "All hands stand by to get ship under way." "You don't seem to be in any haste to do anything, you two."
"What is the use of being in a hurry to get shot at?" said Perkins. "Wait until you hear the call to quarters, and then you will see us get around lively enough. But we shall not have so very much fighting to do to-day. I heard Mr. Watkins tell the officer of the deck this morning that this battle will be merely preliminary. When the soldiers get a foothold on the Island you'll see fun, unless the rebels run away."
"Where is my station in action?" asked Marcy.
"Close at the old man's side, wherever he happens to be," replied the master's mate. "And I will tell you, for your consolation, that he always happens to be in the most dangerous place he can find. There he is on the bridge, and perhaps you had better go up to him."
The bridge was a platform with a railing around it, extending nearly across the deck just abaft the wheel-house, and when Marcy mounted the ladder that led up to it, he found himself in a position to see everything that was going on. The captain was standing there with his hands in his pockets, but he seemed more like a disinterested spectator than like a man who was about to take a ship into action, for he had not a word to say to anybody. He wore a canvas bag by his side, suspended by a broad strap that passed over his shoulder; and if Marcy could have looked into it, he would have found that it contained a small book whose cloth covers were heavily loaded with lead. This was the signal-book—one of the most important articles in a man-of-war's outfit. The captain always kept it where he could place his hands upon it at a moment's notice, and if he found that his vessel was in danger of being captured, he would have thrown it overboard rather than permit it to fall into the hands of the enemy.
For the first quarter of an hour or so Marcy Gray had nothing to do but keep out of the way of the captain, who walked back and forth on the bridge so that he could see every part of the deck beneath him by simply turning his head, and watch the gunboats fall into line one after another. The ease and rapidity with which this was done surprised him. The several commanders knew their places and got into them in short order, and without in any way interfering with the vessels around them. If the inanimate masses of wood and iron they commanded had been possessed of brains and knew what they were expected to do, they could not have done it more promptly or with less confusion. It was a fine and inspiriting sight, and Marcy Gray would have walked twenty miles to see it any day.
"The flagship is signalling, sir," said a quartermaster who was on the bridge with him and the captain.
Marcy turned about and saw a long line of different-colored streamers traveling up the Southfield's main-mast. When it reached the top and the breeze had carried the flags out at full length so that the captain could distinguish them, he took down the number they represented on a slip of paper, and turned to the corresponding number in his book to see what the signal meant. This he wrote upon a separate piece of paper which he held in his hand.
By the time the vessel was fairly under way several signals had been made from the commodore's flag-ship, and finally a rattle was sounded somewhere below; whereupon the blue-jackets came running from all directions, but without the least noise or disorder, and took their stand by the side of the big guns to which they belonged. When the command "cast loose and provide" had been obeyed and every man was in his place, the roll was called by the commanders of the different divisions, the sailors responding by giving the names of their stations thus:
