This is the continuation of our previous post: Analysis for Force Ratios using the Campaign Data Base (CaDB) | Mystics & Statistics (dupuyinstitute.org)
In that post was a table showing the force and losses differences between battles won by the attacker, the defenders and those that are drawn. Below is a follow-up table, showing the force ratios for all the campaigns:
Force Ratio Attacker wins Defender wins * Draws ** Notes
0.30 1 Suomussalmi
0.52 to 0.73 6 2
0.77 to 1.00 7 5
1.01 to 1.25 14 3 1
1.27 to 1.50 8 3 1
1.55 to 1.75 9 3
1.78 to 2.00 11 5
2.02 to 2.50 10 6 2
2.51 to 2.92 8 1 ****
3.01 to 4.00 8 4 *** 1 **** Loos (3.97) – defender wins
4.02 to 4.94 8
5.79 to 7.33 5
10.00 to 11.21 2
Notes:
* Removed from this seven engagements coded as “limited action” and “limited attack.” Their ratios were 0.58, 1.51, 2.90, 2.90, 3.58, 6.55, 12.38
** Removed from this 15 engagements coded as “limited action” and “limited attack.”
*** Three World War one engagements (Festubert at 3.01, Chemin des Dames at 3.33 and Loos at 3.97) and First Cassino (US) at 3.12.
**** Gothic Line Stalemate I at 2.58 and Gothic Line Statement II (US) at 3.08
These are slides 19 and 20 of my briefing. Now, I do not make conclusions on this slide in this briefing or even observations, but…. there are a few that could be made looking at this table. First, a three-to-one rule doesn’t really apply. Second, the defender never wins above four-to-one. Third, clearly there are a lot of factors included in these campaigns beyond simple manpower counts, and…. fourth…. you tell me?
The next slide of my briefing goes into the Section III of the briefing: “Influence of Human Factors on Combat.” This is all drawn from War by Numbers… so… read the book. I will skip that and my next post will pick up at Section IV of the briefing “What is necessary to have a good chance of generating a breakthrough.” Probably do that post next Tuesday.
I would like to understand more about how your campaign system works. Is it map based, does it allow for user driven manoeuvre and does it allow for force attrition due to supply, terrain and desertion? Would you have time to give us an overview?
The CaDB is simply a database of 196 operations, described after the fact. It is listed here along with a screen shot: https://www.dupuyinstitute.org/data/cadb.htm
We have never developed a “campaign system” per se, although we have analyzed campaigns (for example see the books If War Comes: How to Defeat Saddam Hussein and Future Wars: The World’s Most Dangerous Flashpoints.
