French column: a verb of motion, not a battering ram
In a common image of the Napoleonic Wars, the French infantryman advances in a dense column, like a living battering ram: he barely fires, moves blindly, and eventually runs into a thin British line, which fires at him point-blank. This image has been passed down from book to book for decades. The paradox is that the army famed for its columns explicitly recognized in its own regulations that the line is superior to fire.
The logic of the system: the charter of 1791
French Infantry Regulations of 1791, officially Règlement concernant l'exercice et les manœuvres de l'infanterie The decree of August 1st set the rules for formation for the revolutionary and Napoleonic armies. It described in detail lines, columns, squares, and open formations. The column here was not the assault battering ram it is often portrayed as, but the workhorse of movement and concentration.
Without going into the details of the regulations, let's summarize the main points: the regulations recognized several types of columns, distinguished by the unit at their core. In a battalion column, units march one after another, each in its own formation. In a company column, the battalion is broken down into smaller units, making such a column easier and quicker to deploy into a line or reform on the move. Finally, the narrowest columns were formed by divisions (each division here being a pair of companies) or by platoons, for particularly tight spaces. The smaller the unit at the core of the column, the narrower its front. Each type had its niche. The regulations explicitly recommended the use of columns in several situations.
- For passing through defiles - narrow passages, roads between hills, bridges.
- For movement over rough terrain where the line quickly breaks and loses formation.
- To attack narrow sections of the front: villages, redoubts, individual fortified points.
- To facilitate control when the commander needs to quickly turn a unit and move it under fire without being stretched.
The idea behind this is simple: a line shoots better, while a column marches better. A line deploys the front and provides many barrels per unit of length, but is poorly suited to difficult terrain and rapid movements. A column is optimized for movement, compactness, and control, but sacrifices some firepower. Nowhere in the regulations did a column command a frontal attack across an open plain without deploying. On the contrary, it explained in detail how to deploy it into a line before the decisive clash. The column gets the troops to the point, and the line does the firing.
March column and attack column
One of the key features of French practice is the distinction between a march column and an attack column. While this isn't always spelled out in the regulations, in the service, officers perceived different objectives and risks in these formations.
A march column is a highly compressed, compact formation with minimal frontage. Its purpose is to move a unit along a road or trail, quickly cover distances, and maintain command while marching. Battalions march one behind the other, with high density and minimal frontage. This is a formation for movement, not combat. Such a column can quickly move a regiment or brigade without scattering units across the field. The price of compactness is obvious: if such a column suddenly comes under heavy fire, it will be extremely vulnerable, because too many men are concentrated in a small area.
An attack column is a different matter. It's formed with an eye on the upcoming engagement. It's not yet a line, but it's also not just a marching formation. The commanders intended it to remain relatively compact and manageable, yet still be ready to quickly deploy into a line for firefighting or, if the opportunity presented itself, to bring the matter to bayonet point without dispersing. Therefore, the attack column was often formed by battalions, with intervals between them, rather than tightly packed together. The commander had a tight, obedient cluster of battalions at his disposal, which could be turned, deployed, or pushed forward.
For a French officer of the early 19th century, the attack column was valuable precisely for its reversibilityThis isn't a final, dogmatic formation, but a state from which it's easy to transition to a line or a bayonet-on-battle formation. A marching column, on the other hand, is designed for movement and is used in combat as needed, in the event of a sudden encounter, or quickly transformed into something more suitable.
The logic of rapprochement
Modern scholars (for example, Rory Muir in "Tactics and the Experience of Battle in the Age of Napoleon" or Günther Rothenberg) have long shown that French commanders weren't fanatics of the column and understood its limitations in firepower. The division is simple. A line is more effective in a firefight because it provides more muskets facing the enemy. A column is easier to maneuver and approach because it holds formation better and can more easily traverse difficult terrain. Hence the standard approach sequence.
- Column approach. The regiment or brigade moves forward, taking advantage of folds in the terrain, forest belts, and buildings to reduce the time spent under heavy fire.
- Support artillery and riflemen. In front of the column and next to it there are tirailleurs — skirmishers in open formation, as well as batteries. Their job is to soften the defense, disrupt the formation, and force the enemy to shoot less efficiently and with greater nervousness.
- Reorganizing the formation before the decisive moment. The commander either deploys the column into a line and engages in firefighting, or, without wasting time, leads it to bayonet point if he believes the enemy has already been broken.
- Using columns as reserves. Deep in the formation, a column is easier to turn and throw in the right direction than a long line.
In this context, the column is not contrasted with the line as an "incorrect" formation versus a "correct" one. These are two complementary forms, between which the commander constantly switches. Ideally, the column brings the men to a position, after which they either deploy into a line and open fire, or with a short rush complete a prepared bayonet charge.
When the column becomes an assault column
This doesn't mean that the column never served as a direct assault tool. Campaign regulations and practice allowed for such a scenario, but under specific circumstances. First, a narrow attack front: a village, a redoubt, a bridge, a section of a fortified position. A line cannot be deployed across such a gap, and a column of battalions or companies allows for a dense mass of bayonets to be squeezed into a confined space. Second, a clear superiority in spirit and numbers, when the commander relies on a decisive bayonet charge, without delaying a firefight. Third, the need to break through a localized area, concentrating the attack on a single segment instead of a general firefight along the entire front.
These scenarios align with Napoleon's image as a master of the tactical strike. At the campaign level, he would concentrate his forces into a fist and strike at a key point. At the battle level, the column is the same principle of concentrating masses on a narrow strip. However, the regulations did not mandate the column as an assault formation on open ground, but merely permitted it where it was advantageous. To equate this with the prescription "always attack in column" is to distort the doctrine. This, incidentally, is the main line of debate in historiography. Some authors believe the French deliberately relied on the bayonet charge of columns, while others believe they simply often failed to deploy into a line under the pressure of time and fire. This will be discussed in subsequent materials.
It's easier to see all this in a simplified, yet typical, episode. A French regiment of three battalions receives orders to attack a position in rough terrain: a slope with copses ahead, a road below, and beyond that, an open height occupied by an enemy line. The regiment advances in a column of battalions, with intervals for maneuver; skirmishers are scattered ahead and on the flanks, firing at the enemy and preventing them from accurately firing at the lead companies. The column ascends the slope, partially obscured by the terrain, trees, and cannon smoke.
At the crest, the terrain levels out, and the moment of choice arrives. Beyond lies open space, where the column will be clearly visible and vulnerable. The commander gives the signal to deploy: the lead battalion deploys its companies laterally, so that the previous depth of the column becomes a wide front. The following battalions either repeat the maneuver or remain in compact reserve. The line engages in a firefight, muskets firing volleys, skirmishers working the flanks. If the enemy's fire weakens, the line advances; if the enemy holds firm, the commander reinforces it with a second battalion.
And here a second dilemma arises. If the enemy sinks opposite the lead battalion, the commander can cease fire and engage with bayonets; the line transforms into an attacking formation, while the second battalion, remaining compact, supports the attack or expands the breach. The column here is a means of approaching, the line a means of fighting with fire. Another solution is also possible: not to deploy the lead battalion, but to advance the column to bayonet contact. But this is a conscious choice based on the situation, not a dogma of the regulations.
Сonclusion
The French column of the Napoleonic era was not a mythical battering ram, bound to mindlessly smash into any line. The 1791 regulations and practice saw it primarily as a tool for approach, maneuver, and concentration, suitable for defiles, difficult terrain, and concentrating forces in a narrow sector. Officers understood that a line is stronger under fire, and they made plans accordingly. Only with a narrow front, superior morale and numbers, or the need for a local breakthrough did the column become a fully-fledged assault formation.
But all that is a separate discussion. What remains unexplored is why the columns didn't always have time to deploy: training, lack of time, fire pressure, the psychology of dense formations. A separate topic is the Peninsular War, where the French flexible formation system collided with the British rigid double line and gave rise to one of the most enduring myths in stories tactics. We'll look into that next.
