"Runkle, go to the corporal of marines and ask him to send two men here. Then stand by."
"Aye, aye, sir."
Runkle was off like a shot on his errand and soon returned with two marines.
"Now, men," Dave directed, pointing to the doors, "batter them down.
That door, first."
As the men aligned themselves for the a.s.sault, Darrin, mindful that the sham Prince was armed and might prove ugly, stood by with his revolver drawn.
Bang! crash! The door was down.
"It will be wise to surrender to superior force," Darrin called sternly. "We shall shoot to kill at any sign of resistance."
As the words were uttered in French the marines did not understand, but they advanced unhesitatingly on Mender, disarmed him and led him outside the room.
"Take care of him, Runkle," ordered Dave. "Now, marines, that other door!"
Down came the barrier, and Dalny, shaking and white, was brought out to keep Mender company.
"Break down every door that"s locked," was Darrin"s next order.
Within five minutes a little, quaking brown man was secured and led out. All the locked cabins had now been entered.
"You"re the j.a.panese marquis, are you?" Dave jeered. "Do you find, Marquis, that it pays any better than being a Filipino mess attendant?"
The Filipino hung his head without answering.
"Take these prisoners to the corporal of marines, and ask him to iron them and watch them closely," Dave directed. "Runkle, do you know where Lieutenant Whyte is?"
"In the hold, sir, or was."
"Follow me, then, and we"ll see if we can find him."
Down in the main cargo hold forward, Dave and Runkle came upon Whyte and a party of English and American sailormen.
"Ah, there you are, Mr. Darrin," called Whyte. "We"ve been making a jolly big search through the hold, but, except for ship"s supplies, it appears to contain nothing very interesting. However, we shall have time to examine it further later on. And you?"
"I have three prisoners," Dave explained, and told who and what they were.
"Take them with you, Ensign, if you have room on your launch," Whyte directed. "I will now take my men above and post a guard, so that you may withdraw your own guard and get under way at once."
"We have done well so far," Dave answered, as he gripped the English officer"s hand. "I pray that we may be permitted to do as well all through the night."
Runkle was sent through the craft to recall all of the American sailors.
When Dave reached the deck he found that the entire crew of the yacht, including the engine-room force and the stewards, had been rounded up and driven to the deck.
"Over the side," directed Darrin, as his men, recalled, gathered near him. He followed, but went over last of all. Orders for casting off and shoving clear were instantly given.
"Keep the engines up to their best performance all the way," was Dave"s order. "Boatswain"s mate, watch sharp for the courses, as I may change frequently."
"Aye, aye, sir."
Heading out of North Channel, Dave drove back for Valetta, keeping about a mile off the coast.
After making a few knots, he came abreast of another British launch that lay further to seaward. With lantern signals the Englishman asked:
"Is the submarine supposed to be loose?"
"Yes," Dave had his signalman reply.
"Where?"
"Don"t know."
"I"m here to warn incoming ships against entering Grand Harbor to-night," the Englishman wound up. "Are you seeking the submarine?"
"Yes," Dave had flashed back.
"Good luck to you!" came heartily from the English launch.
"Thank you," was Darrin"s final response.
The searchlight of Dave"s launch was swinging busily from side to side, searching every bit of the water"s surface that could be reached.
"If the submarine comes up, Runkle, you may be the first to sight her," Dave smiled to that seaman, who stood beside him.
"Aye, aye, sir; if I sight that craft I won"t be mean enough to keep my news to myself."
"I wonder where Dalzell is," thought Dave. "What is he doing in this night"s work?"
As for Ensign Dave, his every nerve was keyed to its highest pitch.
Outwardly he was wholly calm, but he felt all the responsibility that rested upon him to-night, as did every other officer who commanded a launch from either fleet.
Searchlight and naked vision were not enough. Almost constantly Darrin had his night gla.s.s at his eyes.
Suddenly, as the light shifted over the water, Dave thought he caught sight of something unusual.
"Steady with that light there, signalman," he commanded suddenly.
"Back slowly to port with the beam."
Darrin forced himself to be calm.
"Steady," he called, again. "Hold the light on anything you see, signalman."
"Aye, aye, sir; I _do_ see something," replied the man who was manipulating the searchlight.
That he did see the mysterious something was proved by the manner in which he kept the light upon it.
