Formations and Tactics
While Napoleon is best known as a master strategist and charismatic presence on the battlefield, he was also a tactical innovator. He combined classic formations and tactics which had been used for thousands of years, with more recent ones such as Frederick the Great's "Oblique Order" (Best illustrated at the Battle of Leuthen) and the "Mob tactics" of the early Levée en masse armies of the Revolution. Napoleonic tactics and formations were highly fluid and flexible. In contrast, many of the Armée's opponents were still wed to a rigid system of "Linear" (or Line) tactics and formations, in which masses of infantry would simply line up and exchange vollies of fire, in an attempt to either blow the enemy from the field or outflank them. Due to the vulnerabilities of the line formations to flanking attacks, it was considered the highest form of military manoeuvre to outflank ones' adversary. Armies would often retreat or even surrender if this was accomplished. Consequently, commanders who adhered to this system would place a great emphasis on flank security, often at the expense of a strong centre or reserve. Napoleon would frequently take full advantage of this linear mentality, by feigning flank attacks, or offering the enemy his own flank as "bait" (Best illustrated at the Battle of Austerlitz and also later at Lützen), then throw his main effort against their centre, split their lines and roll up their flanks. He always kept a strong reserve as well, mainly in the form of his Imperial Guard, which could deliver a "knockout blow" if the battle was going well or turn the tide if it was not.
Some of the more famous, widely used, effective and interesting formations and tactics included:
- Line (Ligne): The basic three rank line formation, best used for delivering volley fire and was also a decent melee formation for infantry or cavalry, but it was relatively slow moving and vulnerable on the flanks.
- March Column (Colonne de Marche): The best formation for rapid or sustained movement of troops and a good melee attacking formation, but it offered little firepower and was also vulnerable to flank attack, ambush, artillery and "funneling".
- Wedge (Colonne de Charge): An arrow or spearhead shaped cavalry formation, designed to close rapidly and break the enemy's line. Classic, and effective, mounted formation used throughout history, and still used by tanks today. But if the wedge is halted, or its attack loses momentum, then it is vulnerable to counter-pincer attack on its flanks.
- Attack Column (Colonne d'Attaque): A wide column of infantry, almost a hybrid of line and column, with light infantry skirmishers in front to disrupt the enemy and screen the column's advance. Once the column closed, the skirmishers would move off to its flanks, then the column would fire a massed musket salvo and charge with their bayonets. An excellent formation against a standard, thin line. The Attack Column was developed from the "Mob" or "Horde" tactics of the early French revolutionary armies. Its disadvantages were a lack of massed firepower and vulnerability to artillery fire.
- Mixed Order (Ordre Mixte): Was Napoleon's preferred infantry formation. Some units (usually regiments or battalions in size) would be placed in line formation, with other units in attack column behind and in between them. This combined the firepower of the line with the speed, melee and skirmishing advantages of the attack column. It also had some of the disadvantages of both, so support from artillery and cavalry were especially vital for this tactic to succeed.
- Open Order (Ordre Ouvert): Foot and/or horse would spread out by unit and/or individually. This formation was best for light troops and skirmishers. It allowed for rapid movement, especially over "broken" or rough terrain such as hills or forests, and offered the best protection from enemy fire since the troops were spread out. Its disadvantages were it did not allow for massed or volley fire and was terrible for melee or close quarters fighting and thus, especially vulnerable to cavalry.
- Square (Carré): Classic infantry formation for defence against cavalry. Soldiers would form a hollow square at least three or four ranks deep on each side, with officers and artillery or cavalry in the middle. It offered infantry their best protection against charges, especially on good defensive terrain such as on the top or reverse slope of a hill. Squares were slow moving, almost stationary targets, however. This, along with their density, made squares very vulnerable to artillery and to a lesser extent, infantry fire. Once broken, squares tended to completely collapse.
- Flying Battery (Batterie Volante): Designed to take advantage of French artillery's mobility and training. A battery would move to one area on the field, lay down a short, sharp barrage, then rapidly redeploy to another area and fire another barrage, then quickly redeploy again, etc. The combined, cumulative effect of numerous batteries doing this all along the enemy's lines could be devastating. The horse artillery were especially well suited for this tactic. Napoleon used it to great success in the Armée's early campaigns. Its flexibility allowed him to quickly mass well-aimed fire anywhere it was needed. But it required superbly trained and conditioned artillerymen and horses as well as close command, coordination and control in order to work.
- Grand Battery (Grande Batterie): An alternative artillery tactic, when circumstances prohibited the flying batteries. Artillery would mass its fire at a single, crucial point on the battlefield (usually against the enemy's centre). It could be devastating if the enemy was caught by surprise or in the open. But massing large numbers of guns in a single area without the enemy's knowledge could be tricky. Once the batterie opened fire and its target became clear, measures could be taken to avoid it. It was also vulnerable to Counter-battery fire from enemy artillery and needed protection from cavalry attack. Although this has become the most well known French artillery tactic, Napoleon preferred the flying batteries and used it only when he had to or thought it posed a better chance of success. Often at the start of a battle, he would mass batteries into a Big Battery, then after a few salvoes, break up it up into flying batteries. In the early campaigns it was rarely used, but as the quantity of the Armée's horses and quality of its artillerymen declined, Bonaparte would be forced to employ it much more frequently in later battles.
- Boar's Head (Tête du Sanglier): Was another hybrid formation, somewhat like the mixed order but combining all three arms into a wedge-like square, which could be used for assault or defence. Infantry would form a short, but thick, line many ranks deep on the front, which would be the boar's "snout" (boutoir). Behind them would be two groups of artillery batteries or the "eyes" of the boar. On their flanks and behind them, in oblique order, would be other infantry in column, line or square to form the boar's "face". Protecting their flanks and rear would be two groups of cavalry, which would serve as the boar's "tusk". This was a highly complex formation, which could not be formed as easily or quickly as the others. Once formed, except for the tusks, it had slow mobility. It was, however, faster moving than the traditional square and less vulnerable to artillery or infantry fire. The "tusks" also gave it stronger offensive capabilities. It would later be employed to great effect during the French conquests in North Africa during the 1830s and 1840s, and would be used up until the 1920s.
