This, which is the only object, is certainly an important one for retaining both modes of marching off with large bodies.
The advance from the centre as a definite evolution naturally comes to an end on account of what has just been stated, and can only take place accidentally. An advance from the centre by one and the same column in strategy is, in point of fact, nonsense, for it supposes a double road.
