Under the pressure of a war to the death, all that was best, all that was most human and gentle on each side was crushed out by military necessity.

On the other, vague and sadly misguided yearnings for a nobler, less materialistic life were cleverly transformed by the reactionary leaders into vindictiveness against the revolutionaries.
