"Put your hands up and stop this nonsense!" commanded the young officer, stepping forward, holding the revolver at his belt, the muzzle covering the body of the swarthy foe. The Mexican proved to possess no mean courage. With his knife-hand uplifted he sprang at Hal. At that very instant a form hurled itself through the air. Private Simms fell at the feet of the Mexican. Without pause the soldier wrapped his arms about the Mexican's knees, throwing the fellow backward with jarring force. In another second Simms had possessed himself of the knife. "Good!" came a devout chorus from the five bound but watching soldiers. "Great!" "That was a fine specimen of soldierly wit and promptness, Simms," commended Lieutenant Hal heartily. "Not half equal to what I've heard that you've done in the Philippines and elsewhere, sir," replied Simms modestly, as he seated himself on the fallen foe. "Will you take this knife, sir, and free the other men, or shall I leave this fellow in your care while I set the men free?" "I'll free them," agreed Hal, taking the knife. Inside of a minute the young officer had five more serviceable soldiers at his orders. "Now, lash these two rascals," commanded Lieutenant Overton. "This fellow, first, whom I was obliged to beat with his own revolver." The tying was done by two of the soldiers. Then the wretch whom Simms bestrode was treated to some of the same sort of consideration. The pair of Mexicans were laid side by side, after which the soldiers sprang to get their cartridge belts and rifles. "Check and Varnum, you two stay here with your prisoners, and give them no license to shout or pass signals. Check, fix your bayonet, and stand over these fellows. If either opens his mouth, shove your bayonet into it. Varnum, make it your business to watch over Check and see to it that he doesn't get the noose from behind, as all of us did once." While speaking Lieutenant Overton was fastening on his own recovered revolver and cartridge box. "Now, you other four men," he concluded, "come with me. Silence and soft steps must be our watchword. Unless we have the worst sort of evil luck we'll find out what's going on at the water front." The distance was not great. Hal did not make the mistake of moving his abridged command of four men down the road. Instead they kept to the woods or behind bushes as much as they could. As he came within sight of the water Lieutenant Hal held up his hand--a signal to halt. Then he peered through the darkness. "Just about as I had supposed," he whispered. "Guarez has a tug in at the pier--a steam craft that will move out, as it came in, without lights." "Queer, sir, that some of the other men haven't acted--they must have seen the tug come in."
