|Four French battalions converge on the British garrison at Aveiro. Are they using intervals in their deployment?
On the French right flank of their army, a division of 4 battalions (72 figures each or 360 figures in total) formed up in a massive column (see the picture above), sending three battalions over the bocage, disordering the battalions, and hurling into the thin red line of British (the 52nd Light Regt, I believe). The French had nearly 216 figures (with 72 figures in support ) to fight with maybe 70 British. Any guesses which side won the melee?
If you guessed the French, then you were wrong. As I understand it, four of the five battalions in the first wave of the attack failed their morale and routed back over the hedges. Eventually, they were able to reform and renew the attack, finally capturing the little village of Aveiro, but at the cost of more than half of their troops.
Now let us take a look at how General de Division Morand deployed his battalions during the opening moments of the Battle of Auerstadt in October 1806. Notice how Morand has deployed his battalions in a sort of checkerboard manner with considerable intervals between each unit so that they have the flexibility to change formation into line, column or square, as the situation required.
|Morand's Deployment at Auerstadt. From Napoleon's Finest, Davout and His 3rd Corps, Combat Journal of Operations, 1805-1807, Military History Press, 2006, page 66.
A closer look at the map indicates that the interval between two columns of grand divisions was 250 yards side by side, and 90 yards between the second and third rows of battalions. Furthermore, each battalion formed in column of grand divisions occupied a frontage of 44 yards and a depth of 88 yards (see diagram below). And to top things off, Morand has used the l'ordre mixte by deploying two of his legere battalions in front of the division: the 2/13 Legere on the left is in a serre en colonne formation (close in column) as protection against a likely Prussian cavalry attack, while the 1/13 Legere is deployed to the right in a line formation. Both battalions have deployed their skirmishers to their front and there is a section of two 4-pounders limbered between the two Legere battalions, ready to deploy.
Now my scan of the diagram cut off the right hand side of the page, so let me tell you that after the first line of 13 Legere battalions, Morand has deployed the four battalions of the 51 Regt. de Ligne and the 61e Regt. de Ligne in the second row of the divisional formation. Each regiment of two battalions has a two gun section of artillery deployed between the two battalions.
The third row of battalions (1/17 Line and the 2/30 and 1/30 Line are also deployed in columns of grand divisions with three more 2-gun sections of artillery limbered in support. Every battalion in the division has its skirmishers in front of the parent battalion.

I am not trying to be critical of the way that the French tabletop commander deployed his battalions or of his decision to rush the town of Averiero with overwhelming force. It made a certain amount of sense from a wargaming standpoint, but the wargame deployment was quite different from the deployment that a French General a Division would have employed in battle.
I want you to take another close look at the intervals that Morand used at Auerstadt as he advanced towards the Prussian army. Now think about how that might translate to the table top. Just off the top of my head, I would estimate that one of my stands of 12 French infantry occupy a frontage of 4 inches and so a column of divisions would have a frontage of about 8 inches. So at the very minimum, our table top general should have had 8 inches of space between each battalion. The 8 inch interval could have then been filled by another battalion deployed behind the first row of battalions, ready to support the pending melee with the British. Of equal importance, there would have been a gap through which the front French battalions could have retreated or routed through when they failed to win the melee.
Had this checkerboard formation been used:
(British Line is Here facing the French (M) )
^ ^ ^
MMMM MMMM MMMM
MMMM MMMM MMMM
MMMM MMMM MMMM
... then the first row of three French battalions could have engaged the British regiment in line. They now have an avenue in which to retreat, if needed. Even after routing, the British are disordered from being in the melee and now the second wave of French battalions (2 btns) can charge in and have the advantage since they are in good order whilst the British are disordered.
This is something to think about the next time you are playing in a wargame: am I using enough interval between my troops in a manner similar to their historical deployment, so that if something bad does happen, my troops have an avenue of retreat. Then the second wave of battalions can move in to finish off the opponent.
