Gee, I just posted this in the Command Radius thread. Please realize that the CR thread has taken over the entire world and it and admiring sons-of threads are the only allowed napoleonic reality for the rest of our lifetime.

NEXT POST. Why you do not want to have a dangling end of line.
Let me make some comments on the horrible mismatch that happens when an unit is attacked on the end of a line by a column. Worse yet, if the end of a line being attacked from an exterior angle. The purpose is to support the wargame philosphy of keeping brigades in a close spatial association.
The conventional "wisdom" is that a line of battle will have all guns shooting at an approaching column, whereas the column will only have a few guns shooting. So there's a tremendous mismatch in firepower and columns don't stand a chance. What is missing from this is that a battalion in line is LONG compared to the range of the smooth barrel musket and that soldiers who are in LOB but far from the point of attack are not really in the fight. What's also missing is that if a column can hit the end of a line in some fashion, the advantage is all with the column.
I've run some analog calculations (a.k.a. drawing up to-scale little squares and different templates on an excel spreadsheet the size of a battalion in line and of a close column of attack) and considered a number of cases. For discussion here consider three simple cases:
------------------------------------------------------
[1] a close column of attack hitting the center of a battalion line of battle ("LOB")
[2] a close column of attack hitting the end of an unsupported line and
[3] a close column of attack hitting the end of an unsupported line from a 45 degree oblique angle, from the outside.
--------------------------------------------------------
The line of battle is 215 files wide and each file is 30 inches wide. Each soldier can fire at an angle of 45 degrees from his front (otherwise he blows the head off of one of his own people). The attacking column is 22 yards wide and 30 yards deep. Only the first two ranks can fire- actually I'll be counting the number of "files" that can fire.

[1] If the attacking column comes directly perpendicular into the LOB with the center hitting the center of the LOB you have approximately the following proportions of the LOB able to fire.
AT CONTACT Many of the LOB troops can't get a shot at the column because they can't twist and fire through their own troops. 50 files can shoot at the sides of the incoming column at ranges between 0 and 43 yards. 25 files shoot at zero range. 35% of the defenders can shoot.
AT 50 YARDS 213 out of 215 files can fire. The ranges are between 50 and 99 yards. This is a good killing zone. 99.1% of the defenders can fire.
AT 100 YARDS 100% of the defenders can fire. The ranges are between 100 and 124 yards.
AT 150 YARDS 100% of the defenders can fire. The ranges are between 150 and 167 yards, which is getting a little long for the muskets.

[2] If the attacking column comes directly perpendicular into the LOB with the center hitting the end of the line you have approximately the following proportions of the LOB able to fire.
AT CONTACT 40 files out of 215 can fire. 18%
AT 50 YARDS 90 files out of 215 can fire. 42%
The average range is ~ 65 yards
AT 100 YARDS 136 files out of 215 can fire. 62% total can fire. However 23% of the defenders are firing at greater than 150 yards. This is very long range and largely ineffective. Only 40% are firing in the 100 to 150 yards range, which isn't that hot either.
The attacking column is only firing one eight of its files. (12%) but all are firing at the minimum range, not at a variety of longer ranges. Also as the front ranks get killed, they are replaced by back ranks who bring up loaded muskets. This increases the firepower.
===================================================
DDDDDDDDDDDDDDDDDDDDDDDD AA AA
If the attacking column comes in at a 45 degree angle from the side of the LOB and hits the end of the LOB you have approximately the following proportions of the defending LOB able to fire.
AT CONTACT 3.5 files out of 215 can fire. 9%
AT 50 YARDS 3.5 files out of 215 can fire. 9%
AT 100 YARDS 3.5 files out of 215 can fire. 9%
The attacking column is only firing one seventh of its files. This is 12% of its files. 12% is greater than 9%. The attacking column wins the gunfire contest on the way in. As to the melee, it starts off about 10 to 1 odds.
===========================================
My point is that any wargame rules should make an attack on the end of a line by a column be a really really bad experience for the defender. This will limit the "
zippy battalions" and force brigadiers and colonels to keep units together with flank support. A close column of attack should be able to curve around and hit the end of a LOB- it doesn't even have to be directly from the side or rear to be deadly. Put attacking skirmishers in front of the attackers to hide the direction of the column. Bad news for the defender. Pin the defender by moving another LOB close to them in front. Bad news for the defender. If the defending LOB refuses the flank, they have weakened themselves because the attacking column can hit the hinge and now the defender has a lot of guns facing empty space and not the attackers."
