In the future war every body of troops holding itself on the defensive or found taking the offensive, when it is not the question of sudden assault, will have to fortify itself in a chosen position and the war will be confined principally to the form of a series of combats in which the possession of fortified positions will be disputed, and in which the assailant will have to meet the accessory defensives in the neighbourhood of the fortifications such as barricades, barbed wire, etc.
