"Ah, no, my friend," replied the Frenchman, smiling. "They won't know what the message means, but your voice and language will mean to them that Americans are occupying the sector in front of them, and we want to give them that information in another way, n'est ce pas?"
Undoubtedly there was some concern in the German trenches just over the way with regard to what was taking place in our lines. Relief periods are ticklish intervals for the side making them. It is quite possible that some intimation of our presence may have been given.
There was considerable conversation and movement among our men that night. Jimmy found it frequently necessary to call the attention of Johnny to some new thing he had discovered. And of a consequence, much natural, but needless, chattering resulted.
I believe the Germans did become nervous because they made repeated attacks on the enveloping darkness with numbers of star shells. These aerial beauties of night warfare released from their exploding encasements high in the air, hung from white silk parachutes above the American amateurs.
The numerous company and battery jesters did not refrain from imitative expressions of "Ahs" and "Ohs" and "Ain't it bootiful?" as their laughing upturned faces were illuminated in the white light.
That night one rocket went up shortly before morning. It had a different effect from its predecessors. It reared itself from the darkness somewhere on the left. Its flight was noiseless as it mounted higher and higher on its fiery staff. Then it burst in a shower of green balls of fire.
That meant business. One green rocket was the signal that the Germans were sending over gas shells. It was an alarm that meant the donning of gas masks. On they went quickly. It was the first time this equipment had been adjusted under emergency conditions, yet the men appeared to have mastered the contrivances.
Then the word was passed along the trenches and through the dugouts for the removal of the masks. It had not been a French signal. The green rocket had been sent up by the Germans. The enemy was using green rockets that night as a signal of their own. There had been no gas shells. It was a false alarm.
"The best kind of practice in the world," said one of our battalion commanders; "it's just the stuff we're here for. I hope the Germans happen to do that every night a new bunch of our men get in these trenches."
While the infantry were experiencing these initial thrills in the front line, our gunners were struggling in the mud of the black gun pits to get their pieces into position in the quickest possible time, and achieve the honour of firing that first American shot in the war.
