"By the time the sun rises tomorrow," Chattan concludes, "we will have one of our very best submarine-hunting task forces on the scene. A light carrier with several antisubmarine planes will comb the ocean night and day, using radar, visual reconnaissance, huffduff, and Leigh lights to hunt for U-691. The chances are excellent that she will be found and sunk long before she can approach the Continent. But should she find her way past this formidable barrier she will find the German Kriegsmarine no less eager to hunt her down and destroy her. Any information she may transmit to Admiral Dönitz in the meantime will be regarded with the most profound suspicion."
