'Some Terrifying Numbers"

[Erpingham]

The difficulty is surely Lanchester wrote over 100 years ago.  He proposed two laws.  Since then there are several other versions (like the logarithmic and the mixed (or asymetric) model where the two sides follow different laws.  There follow from these a set of equations in search of a "general" Lanchester equation.  So, you really have a family of Lanchester laws through time.

BTW, I particularly liked this article, which gives you lots of lanchester equations to play with and tries to apply Lanchester to the Battle of Britain.  Please excuse the inaccuracy of the first page picture.  If you look carefully, you will find a Lanchester Ancient Battles equation.

The difficulty apparently is that I said "Lanchester says" instead of "Lanchester's Square Law says". In the context of a forum discussion I thought it was clear enough what I meant, but apparently not. Never mind.
