Leo Tolstoy: War and Peace

BOOK FOURTEEN: 1812 2. CHAPTER II (continued)

The tactical rule that an army should act in masses when attacking, and in smaller groups in retreat, unconsciously confirms the truth that the strength of an army depends on its spirit. To lead men forward under fire more discipline (obtainable only by movement in masses) is needed than is needed to resist attacks. But this rule which leaves out of account the spirit of the army continually proves incorrect and is in particularly striking contrast to the facts when some strong rise or fall in the spirit of the troops occurs, as in all national wars.

The French, retreating in 1812- though according to tactics they should have separated into detachments to defend themselves- congregated into a mass because the spirit of the army had so fallen that only the mass held the army together. The Russians, on the contrary, ought according to tactics to have attacked in mass, but in fact they split up into small units, because their spirit had so risen that separate individuals, without orders, dealt blows at the French without needing any compulsion to induce them to expose themselves to hardships and dangers.
