Rh were two railroad spur lines from the station, and on these the heavy guns were moved to position to fire, and then run back again. Other spur lines were under course of construction. Jack and Tom, as well as the other airmen, could observe, indicating that other guns were to be mounted, perhaps to take the place of some that might be destroyed.

As a matter of fact, as was learned later, there were but two guns in service at this time, one of the three having burst.

Even as the French squadron came hovering over the place where the German monster guns were placed, the advance of Tom, Jack and their comrades being disputed by the Huns, one of the super-guns was run out to fire on its specially constructed platform.

That this should be done in the very faces of the French was probably accounted for by the fact that the Germans were taken by surprise. It took some little time to arrange for firing one of the big cannons, and it was probably too late, after the French airmen were hovering above it, to get word to the crew not to discharge it.
