leaving Austria on his rear and having Russia in front. If Austria had
launched an army of one hundred thousand men from Bohemia upon the Oder,
it is probable that the power of Napoleon would have been ended; there
is every reason to think that his army could not have regained the
Rhine. Austria preferred to wait till she could raise four hundred
thousand men. Two years afterward, with this force she took the field,
and was beaten; while one hundred thousand men well employed at the
proper time would have decided the fate of Europe.

There are several kinds of war resulting from these two different
interventions:--

1. Where the intervention is merely auxiliary, and with a force
specified by former treaties.

2. Where the intervention is to uphold a feeble neighbor by defending
his territory, thus shifting the scene of war to other soil.

3. A state interferes as a principal party when near the theater of
war,--which supposes the case of a coalition of several powers against
one.

4. A state interferes either in a struggle already in progress, or
interferes before the declaration of war.

When a state intervenes with only a small contingent, in obedience to
treaty-stipulations, it is simply an accessory, and has but little voice
in the main operations; but when it intervenes as a principal party, and
with an imposing force, the case is quite different.
