Every ship in the fleet was now having something to say with her guns; and with their incessant manoeuvring at such close quarters the sea was all torn up by their wakes. Two or three wakes or bow waves would cross each other, and the sea would roll up with a bounding white crest. There were also the wakes of hidden submarines. You could tell them if you saw any by the way they did not stop in one place; they moved on. When a gunner saw a submarine wake he fired; where he wasn't sure he fired anyway. What was he there for? Bang! Boom! Solid shot were ricochetting, piling up little white splashes, and the shrapnel were making little holes and bursting into little white smoke puffs all over the place. You must not forget that it was a beautiful day and a perfectly calm sea with the shore of France looming like a blue mirage on the horizon. It lasted about forty minutes altogether, and through it all the little destroyers--don't forget them--were weaving in and out among the big ships; and on the big ships were thousands of troopers, white life-belts around their olive-drab uniforms, standing steadily by life-boats and rafts. Our fellows on the destroyers did handle their little ships well. And the troop-ships were handled well--no collisions and no gun-shells going aboard anybody else. A few went across other people's bows and sterns, but not too near to worry. And in the middle of it all, our guns made so much noise that before we heard them we saw them--two airplanes, whirring and cavorting about and above us. Whenever they saw a destroyer turn and shoot, they would turn and shoot after the destroyer. They could move about three times as fast as a destroyer, and so quite often beat the destroyer to it. Later the airplanes escorted us into port. They were big, powerful biplanes, and carried a sky-pointing gun mounted forward and the colors of France painted on their little wings aft. They kept circling about us until we made our harbor. Whenever they swooped low enough our troopers gave them a fine cheer. My job being to tell what I saw and heard, I want to say here that throughout the entire melee I never saw one periscope! And there were thousands like me who never saw a periscope. But there were hundreds of others--cool, sensible people--who are ready to make affidavits that they did see periscopes. Why did not more of us see any? Well, a submarine commander needs to turn up his periscope for only four, five, six, or seven seconds to have a look. If you do not happen to be gazing directly at the spot, you do not see it or the white bone which it makes going through the water.
