Jovial Bill Witt had proved such a capital good fellow that Jack and Ted had taken a great liking to him. The three boys were great pals by this time and were always together in their leisure moments. Temperamental Jean Cartier, the smiling little Frenchman who had shipped aboard the Dewey as chief commissary steward, very often joined their circle and spun the boys stories of that dear France and his home near Marseilles.

To-night it was different. There was no levity. Every man seemed to sense the situation and stood to his post of duty grimly conscious of the serious business upon which he had embarked. Through the minds of the lads flitted visions of home and campus.

Jack, dreaming of good old Brighton, was stirred out of his reverie by his chum.

"Do you suppose we will go all the way over under our own power, or will we be towed?" Ted was asking.

"Haven't the least doubt but that we'll stand on our own sea legs," replied Jack. "Don't you remember how we read in the papers early in the war of a bunch of submarines put together in the St. Lawrence River going all the way across to Gibraltar and thence through the Mediterranean to the Dardanelles under their own power?"

Ted did remember, now that it had been called to his mind. It had gripped their imagination at the time; it seemed such a wonderful thing, the fact that submarines small enough to be carried on the decks of huge liners had been able to cross the Atlantic alone and unaided. They had been still further amazed by the feats of the German undersea cargo carrier Deutschland that had made the trip to America and back, and the U-53 that suddenly popped into Newport one summer afternoon.

The night dragged along. Now that they were fairly off, Jack and Ted preferred not to sleep, but rather to keep tabs on the maneuvers of the American fleet. The sea was calm and the Dewey cruised on the surface, with her hatches open. The boys were able to stretch themselves in a promenade on the aft deck and found the night air invigorating as they speculated together on their mission.

They had soon to find out something of the number and character of warships in the fleet of which the Dewey was a unit. As daybreak came stealing up over the horizon they looked about them to discern many other warships all about them. Far to port, strung out in single file about a half mile apart, were three huge liners that they took to be troopships. Deployed around them were destroyers—-four of them—-riding like a protecting body guard. Bobbing about at intervals in the maritime procession were other submarines, their conning towers silhouetted against the dim skyline.

Relieved of duty, Jack and Ted went below and turned in for a two-hour sleep. When they climbed up through the forward hatch again after breakfast it was to find the sun shining bright and the fleet moving majestically eastward.

Chief Gunner's Mate Mike Mowrey confided to them that the Dewey was, indeed, bound for European waters. Lieutenant McClure had opened his sealed orders and learned that he was to report to the Vice-Admiral in the North Sea. Word had been passed around to the ship's officers and they in turn were "tipping off" their men. The Dewey was stripped for action and was to assist the destroyers in defense of the transports in the event of an attack.
