GUARANTIES.
As a guaranty for the execution of the treaty, German territory to the
west of the Rhine with the bridgeheads will be occupied by Allied and
Associated troops for fifteen years. If Germany faithfully carries out
conditions, certain districts, including the Cologne bridgehead, will
be evacuated in five years, certain other districts and territories
nearest the Belgian frontier after ten years, and remainder after
fifteen years.
If Germany fails to observe her obligations during occupation, or
after fifteen years, the whole or part of the areas will be
immediately reoccupied. If before the expiration of the fifteen years
Germany complies with all her treaty undertakings, the occupying
forces will be withdrawn immediately.
All German troops at present in territories east of the new frontier
shall return as soon as the Allies deem wise.
