"We think we have the key to the situation in that chart."
Captain McClure—-who had attained that rank at the time Jack and Ted were made lieutenants—-further explained that he had been designated in command of the ten American submarines that were to launch the spectacular attack. He said he would give his attention almost solely to fleet maneuvers and leave the handling of the Monitor to his lieutenants.
"We will do our best, sir," said Jack, as he squared his shoulders.
The attack was to be staged the following night. Now for the next twelve hours or so the crews of the selected warships were carefully to prepare for the fray and to rest themselves.
The Monitor was put in tiptop shape. Tenders came alongside and gave her stores of fuel and ammunition. The giant torpedo tubes were loaded and the ship's full quota of reserve torpedoes taken aboard. The night and following day were given over to leisure hours. Jack and Ted wrote letters home and to school telling of their promotions and some of their latest exploits.
At nine o'clock of the following evening the submarine fleet received the word to be off.
The attack was planned to be started at one o'clock in the morning under the cover of darkness. Keeping in close touch, the submarines spread out over the sea like a huge fan. Behind them at a distance of five miles moved the supporting column of dreadnoughts, battle cruisers, destroyers, scouts and mine sweepers—-units in the great fleet bent upon the task of smashing the German stronghold.
The Monitor led off in the battle array. Copies of the chart of Zeebrugge, the original that had been found on the converted U-boat at the time of her capture, had been given to every submarine skipper in the fleet. Each had his orders for this all-important night.
"Here we go!" murmured McClure to his aides as he signaled his fleet of submarines forward into the fray.
Picking his way according to the German chart, he set a zigzag course. At length the officers of the Monitor knew they were closing in, and so far successfully. The submarines were running submerged with only the tips of their periscopes showing.
