"All right?" he asked.
"O.K., sir," replied the officer in command of the gun crew. "Show us a submarine, that's all we ask."
"There are probably a dozen or so about here some place," returned Frank. "Keep your eyes peeled and don't wait an order to fire if you see anything that looks like one."
"Right, sir."
The officer turned to his men with a sharp command.
Frank continued his inspection of the ship as the Brigadier dashed toward the vessel in distress, probably ten miles ahead.
Every man aboard the Brigadier was on the alert as the destroyer plowed swiftly through the water. It was possible, of course, that the submarines had made off after attacking the vessel, but there was always the possibility that some were still lurking in the neighborhood.
"Can't be too careful," Jack told himself.
Fifteen minutes later, the lookout was able to make out more clearly the ship ahead of them.
"Steamer Hazelton," he called to the quartermaster, who reported to Jack.
