In all countries which are difficult to traverse, whether the obstacles are mountains, forests, or a peculiar cultivation, a numerous cavalry is useless: that is plain in itself; it is just the same with artillery in wooded countries; there will probably be a want of room to use it with effect, of roads to transport it, and of forage for the horses. For this arm highly cultivated countries are less disadvantageous, and least of all a mountainous country. Both, no doubt, afford cover against its fire, and in that respect they are unfavourable to an arm which depends entirely on its fire: both also often furnish means for the enemy’s infantry to place the heavy artillery in jeopardy, as infantry can pass anywhere; but still in neither is there in general any want of space for the use of a numerous artillery, and in mountainous countries it has this great advantage, that its effects are prolonged and increased in consequence of the movements of the enemy being slower.
But it is undeniable that infantry has a decided advantage over every other arm in difficult country, and that, therefore, in such a country its number may considerably exceed the usual proportion.
