looked as though he were involved in the robbery of a paymaster's
clerk, ended in showing that Nick Rabig was the real culprit. This
completely vindicated Frank, as will be seen in the fourth volume
of the series entitled: "Army Boys In the Big Drive; Or, Smashing
Forward to Victory."

That victory was now in sight. The German cause was doomed. One
great victory remained to be gained, the clearing of the Argonne
forest, wild, tangled, meshed with thousands of miles of barbed
wire, crowded with machine gun nests and swept with a hurricane of
shot and shell. But nothing could stop America's boys now that
their blood was up, and they did much in helping to win here the
final and greatest battle of the war. All the Army Boys, fighting
like tigers, came through unharmed, except Bart, who was wounded
and afterward wandered away from the hospital while temporarily
insane.

The armistice was signed and the Army Boys assigned to the Army of
Occupation with headquarters at Coblenz. At Luxemburg while on the
march they came across an American family who for business reasons
had lived for a time in Coblenz. How they took the head of the
family for a German spy, how they marched as conquerors into
Germany, how Frank was cheered by learning that his mother's
property was sure to come to her, how Bart was found and restored
to his right mind, how by the aid of the suspected spy who turned
out to be a patriotic American they thwarted a desperate German
plot to blow up the fortress of Ehrenbreitstein on the Rhine--all
these and other thrilling adventures are described in the fifth
volume of the series, entitled: "Army Boys Marching Into Germany;
Or, Over the Rhine With the Stars and Stripes".
