The train was now rattling through the town, and a few seconds later it reached the near end of the long bridge across the river.

“I guess here is where I’ll have to jump for it,” thought the young lieutenant. He knew that the guards above would be rushing to the spot where they had last seen him and that they would not hesitate to open fire again. He had no desire to fall a victim to a German bullet.

The train ran out on the trestle; and the edge of the cars was less than two feet from the outside of the bridge. Bracing himself as best he could, Dave took a long breath and then made the leap.

“There he goes!” cried one of the guards.
