"Hullo, c.o.xswain," was Dave's greeting. "Are you to handle the launch to-night?"

"No, sir," Riley answered, saluting. "I am the petty officer in charge of the seamen. c.o.xswain Schmidt handles the launch, sir."

As soon as his party had hurried aboard, Darrin gave the order to cast off. Under slow speed astern the launch joined Lieutenant Cantor's craft.

"I'm glad that I'm to have you on sh.o.r.e tonight with me, c.o.xswain,"

said Dave, heartily.

"Thank you, sir," answered the c.o.xswain, saluting and actually blushing with pleasure.

Soon after Dan's launch ranged up with the other two, and the "_Long Island_" was vanishing in the distance ahead, not a light showing, for it is the privilege of the commander of a war vessel to sail without lights, when the interests of the services may be furthered thereby. Nor did any of the launches display lights.

As each of the boats was to run at slow speed, it was hoped that each landing party would reach sh.o.r.e without detection.

Lieutenant Cantor went over the instructions once more, talking in low tones across the water.

"And above all, remember that there is to be no fighting," Cantor added, impressively, looking straight into Darrin's eyes.

"Punk orders, when each man is provided with a hundred rounds of rifle ammunition, and when each automatic gun is supplied with two thousand rounds!" grumbled c.o.xswain Riley, under his breath.

"Gentlemen, you will now get under way," ordered Lieutenant Cantor.

"You will remember each sentence of your instructions!"

Silently, two of the launches stole away into the night, bound east and west, while the third launch awaited the time to start sh.o.r.eward.

On Darrin's launch there was little talking, and that in whispers.

Dave had made a most careful study of the map, and felt certain that he could give the course straight into the lagoon on which the Acunda mill stood.

"c.o.xswain Schmidt," said Ensign Darrin, in a low voice, when still some four miles away from the proposed place of landing, "when you are close enough to sh.o.r.e to signal the engineer, you will do so by hand signal, not by use of the bell. Seaman Berne will watch for your signals, and convey them to the engineer."

"Very good, sir," replied both c.o.xswain and seaman.

"Probably it won't be my luck to find the American captives at the Acunda plantation," murmured Darrin.

None the less, when he at last sighted the lagoon, his heart began to beat excitedly.

Under reduced speed, now, the launch stole into the lagoon. Less than a quarter of a mile from sh.o.r.e the sugar mill, deserted since the rebellion first took acute form, stood out dimly against the dark sky.

To within a hundred and fifty yards of the mill the launch ran, then swung in at a nearly ruined old wharf.

Ensign Dave Darrin was first to step ash.o.r.e, signing to his men to follow him with all stealth.

"Corporal," Darrin whispered, "unless summoned later, you will stand by the launch with your men, to prevent it being rushed in case the bandits are abroad to-night. c.o.xswain Riley, you will form your men loosely and follow me, keeping about a hundred yards to the rear, making no sound as you advance."

Officer and men were all in dark uniforms, which in the blackness of the night would not be seen at any distance, whereas the white tropical uniforms would have immediately betrayed the raiders.

About seven hundred feet beyond the sugar mill Darrin had already located the house. Like the old mill, the residence was in darkness.

Not a light shone, nor was there a sound to be heard.

"This eerie stretch of ground makes one think of a graveyard," thought Darrin, with a comical little shiver, as his left hand gripped his sword scabbard tightly to prevent it clanking against his left heel.

He turned to look behind him. Riley and twelve armed seamen were following him like so many unsubstantial spectres.

Past the mill, and down the road to the house strode Darrin, but his moving feet made hardly a sound.

A little before the house ran a line of flowering tropical hedge.

Darrin gained this, and was about to pa.s.s in through an opening in the hedge when a figure suddenly appeared in the darkness right ahead of him.

A rifle was leveled at the young ensign's breast, and in a steady voice came the hail that set the young ensign's heart to beating fast:

"_Quien vive_"

It was the Spanish challenge---"Who goes there?"

CHAPTER VII

DAVE DARRIN TO THE RESCUE

Dave's sword hung at his side. His revolver was in its scabbard over his left hip, but just out of view of the sentry.

As to his being in uniform, he realized that the night was so dark that there was little danger of his nationality being discovered.

All these thoughts flashed through his mind in a twinkling, as they should with a good officer.

Darrin's course of action was as swiftly decided.

"Amigo," he replied, tranquilly. "Amigo de los prisoneros!" (Friends of the prisoners).

By the time the second explanation had left his lips Dave had bounded forward, struck aside the rifle, and had gripped the sentry by the throat, bearing him to the ground.

A blow from one of the young ensign's fists, and the fellow lay still.

Espying trouble from the rear, c.o.xswain Riley started his men on a swift run toward the spot. In a few moments the sentry, doubtless badly scared, had been gagged, and bound hand and foot with the handy hitches of jack tars.

"Leave him there," Darrin directed in an undertone. "c.o.xswain, post eight men around the house, and take command of them. I will take the other four men with me."

Swiftly Darrin led his little squad around to the rear of the house, since the front was closed and dark.

A doorway stood open, showing a room lighted by two candles that stood on a table. Around the table were seven men, eating and drinking. Plainly they had not heard the brief scuffle at the front.

With a nod to his four men Darrin led the way inside. Instantly the seven men were on their feet, staring wildly at the intruders.

One man started for a stack of rifles that stood in a corner, but Ensign Darrin hurled him back.

"Don't let any man reach for a gun, or draw any sort of weapon,"

Darrin ordered, quickly.
