it was necessary to have some light, that the channel might be seen without the aid of search or other lights.
As it grew darker each warship put out a single hooded light, showing from behind only; this precaution being taken to keep one vessel from running up into that before her. All the other exposed lights were cut off, and officers and men were alike warned that no noise that was not absolutely necessary should be made. If it was possible, Commodore Dewey intended to run by the batteries on Corregidor Island, and any other batteries in the vicinity, without being discovered. In naval warfare, and in military warfare, too, for the matter of that, to come upon the enemy when he leasts expects it, and thus throw him into more or less confusion, often constitutes a large element of success.
On and on went the squadron, looking like dim phantoms of the night, moving in an irregular line, the Olympia in the lead, and the tiny Petrel and despatch boat McCulloch bringing up together in the rear. Corregidor Island was not yet visible, yet the men knew it might appear in the dim distance at any moment.
