The two craft lay now not more than five hundred yards apart. Across the water sped the fast power launch and came up alongside of the unknown steamship, which displayed no name.
Not a human being was now visible on her deck. An undersized watch officer had appeared on the bridge, but he now vanished.
"Who commands that destroyer?" demanded a voice in English, though it had the broken accent of a German-born speaker.
"I do," Darrin replied.
"Then stay where you are, for you"re covered!" ordered the same voice in a frenzied tone. "We"re not going to have you aboard. Signal the destroyer to make off at top speed and we"ll leave you when she is out of sight. Refuse, and we kill you at once. Refuse, and you lose your life."
"Lower your gangway, and stop your nonsense," Dave ordered, angrily.
"You"re dealing with the United States Navy, and your orders cannot control our conduct."
"Then you are a dead man, at once!" declared the voice of the unseen speaker.
Unnoticed by others, Darrin had given a hand signal to a petty officer in the bow of the launch.
"If you do not lower your side gangway at once, we shall find our own means for boarding," Dave shouted, wrathfully. "Instantly, sir!"
Thereupon half a dozen heads appeared over a bulwark above. As many rifle muzzles were thrust over the edge of the bulwark and a prompt fire began.
Disdaining to draw his automatic Darrin stood up in the launch, the center of such a hail of bullets that his continued existence seemed incredible. Above the reports of the rifles could be heard the voice of Ensign Peters as he directed the swinging around of the launch.
R-r-r-r-rip! The launch"s machine gun came swiftly into play. Bullets rattled against the iron sides of the ship.
Four of the six seamen on her deck were seen to fall back; the remaining two fled as fast as they could go.
Then the muzzle of the machine gun was swung, and a hundred little missiles were driven through the wheel-house.
At an unspoken signal the launch moved in until a sailor in the bow could hurl upward an iron grappling hook. At the first cast it caught on at the top of the rail, while the machine gunners trained their weapon to "get" any one who endeavored to cast off the grapple.
"Up with you!" shouted Darrin. One after another half a dozen sailors raced up the rope, swinging over to the deck.
Dave followed next, then more seamen. All were armed and ready for instant work of the sternest kind.
Two sailors lay dead, rifles beside them. Pools of blood showed that at least two more wounded men had been there, but had fled. No one else belonging to the ship was in sight on deck.
"Boatswain"s mate, take the bridge," ordered Dave, as more men came up on board. "Put two men in the wheel-house. Take command of the deck with such men as I do not take with me."
Calling half a dozen seamen, and ordering them to draw their automatic revolvers, Darrin proceeded to the chart-room. He tried the door, but found it locked.
"Break it down," he ordered, and in a jiffy the thing had been done. But the chart-room proved to be empty.
Further aft Darrin went along the deck-house. The cabins of the captain and two mates were found to be empty.
"We"ll soon know where the crew have gone to," he remarked.
In the dining-room were found three men in dingy blue uniforms, who appeared to be ship"s officers. The oldest, who scowled hardest at the same time, Dave took to be the skipper.
"You command this ship?" Darrin inquired.
"If you say so," replied the man addressed.
"You must, for you are the fellow who ordered me to send my ship away,"
Darrin smiled grimly. "Are you a German?"
"None of your business. Why have you killed two of our crew and hurt others?"
"Drop that nonsense," Darrin retorted, sternly. "You know why we fired on you. And your men slightly wounded two of mine."
"We had a right to," scowled the other.
"You"ll know better, by the time you"ve reached a British prison," Dave rejoined. "Men, place these three fellows under arrest. Search them."
Only the man who appeared to be the craft"s master resisted being searched. He swung at one of the sailors, but Darrin jumped in, knocking him down and holding him to the floor.
"Put irons on this scoundrel," he ordered, sharply, a command so quickly obeyed that almost instantly the defiant one found himself manacled. Then Dave yanked the fellow to his feet.
"You are a bully," growled the prisoner.
"I am," mocked Dave, "when I have fellows of your stripe to handle. Men, you"d better iron that pair, too. They belong to the same outfit."
None of the three proved to have any arms on his person.
"Now, where are the members of your crew?" Dave demanded of the manacled skipper.
"Find them!" came the surly retort.
"In what business is this ship engaged?"
"Find out!"
"Bring these prisoners out on deck," Darrin commanded. Then, as the order was obeyed, Darrin made his way to the bridge.
"Boatswain"s mate, pipe all hands on deck," he directed.
Shrilly the whistle sounded at the lips of the petty officer. But no men came to answer.
"We"ll try other tactics, then," Darrin smiled.
Stepping to the wheel-house door he pulled it open. Inside was evidence of the havoc that the machine gun fire had worked there. Everything had been riddled, including the helmsman, who lay dead on the floor.
At this moment, however, Dave had no time to do more than glance at the dead man. Reaching for the whistle he blew a long blast, and caused the fire bell to be rung, the signal to stand by to abandon ship.
That brought seamen and stokers trooping to the deck, until more than thirty had so appeared.
"Does any man among you understand English?" Darrin called down as he leaned over the rail in front of the wheel-house.
"I do," came from one of the crew.
