Read it through once

A brief dispute followed, as to whether the difference between Northern and Southern moonlight really existed or was only imagined. Moonlight talk drifted easily into talk about artificial methods of dispelling darkness. Then somebody remembered that when Farragut advanced upon Port Hudson on a dark night--and did not wish to assist the aim of the Confederate gunners--he carried no battle-lanterns, but painted the decks of his ships white, and thus created a dim but valuable light, which enabled his own men to grope their way around with considerable facility. At this point the war got the floor again--the ten minutes not quite up yet.
