enemy's corps as they successively appeared. In the same way the
Archduke Charles took an interior position, between Moreau and Jourdan,
in 1796, and prevented them from concentrating their forces on a single
point. Wurmser and Quasdanowich attempted to concentrate their forces on
the Mincio, by moving on the opposite shores of Lake Garda; but Napoleon
took an interior position and destroyed them. In 1815 Blucher and
Wellington, from their interior position, prevented the junction of
Napoleon and Grouchy.

_Diverging_ lines may be employed with advantage against an enemy
immediately after a successful battle or strategic manoeuvre; for by
this means we separate the enemy's forces, and disperse them; and if
occasion should require it, may again concentrate our forces by
converging lines. Such was the manoeuvre of Frederick the Great, in
1757, which produced the battles of Rosbach and Leuthen; such also was
the manoeuvre of Napoleon at Donawert in 1805, at Jena in 1806, and at
Ratisbon in 1809.

_Interior_ lines of operations, when properly conducted, have almost
invariably led to success: indeed every instance of failure may be
clearly traced to great unskilfulness in their execution, or to other
extraneous circumstances of the campaign. There may, however, be cases
where it will be preferable to direct our forces on the enemy's flank;
the geographical character of the theatre of war, the position of other
collateral forces, &c., rendering such a direction necessary. But as a
general rule, interior and central lines, for an army of moderate
forces, will lead to decisive results.
