Here is a more recent version of HB rules with additional explanation of the reasoning behind introducing the rules.viewtopic.php?f=157&t=15947
A few comments though.On LCS rule.
This rule is specifically meant as a fix to the CA's instant square (which is complete nonsense). It is based on the idea that forming square from a line was historically much more difficult maneuver as compared to forming square from a column. It is perhaps not the most practical rule, but in a group of like minded players it works just dine. As a desirable side effect, this rule gives a clear-cut bonus to column formation, which CA never bothered to do. Of course, column will not give any mobility or morale bonus compared to line, but it would allow a more quick response to cavalry threat. No embedded artillery
rule refers to formed up
infantry (battalion or regiment) standing in the middle of operating battery. As for your example with the massive squares in the battle of Piramides, only a part of artillery positioned just outside square could operated as far as I know. As for infantry or cava supporting arty, those normally were smaller loose formations positioned just behind or on flanks of batteries. No sniping general
is not an essential rule, more like gentlemen agreement. It is meant to minimize the rather large penalty effect on the army morale in very early stages
of the battle by directing cannon fire at general. In practice players will just warn the opponent about danger for his general from long-range artillery fire. Players can still (and will) try to take your general down by any other means.No charge through
friendly units is meant specifically to counter a usual in vanilla and also classic NTW3 attack of own cavalry from behind and through own formed-up
unit. This is completely unrealistic and I do not accept your comment as a valid argument. Attacking though own artillery, for instance, or though own routing units (formation broken!) is allowed. There is no problem if there is a slight overlap between units attacking from different directions; that is largely unavoidable in this game. Max one unit per building
rule is based on two observations: (1) a unit in game is a battalion; so, stacking two or more units in a single building looks unrealistic (even in large buildings like farms smaller formations were deployed to hold the building) (2) sending many units in a building could cause lag and also players dropping out of the game, which is undesirable. So, this rule does not prohibit fighting in buildings (those were important events on many battlefields), but it just regulate them to an extent.
As a final remark, the above rules are designed to compensate for the flaws of the engine and make battlefield look a bit more like a Napoleonic battlefield, and not make life of players sour. It does require some effort and trust between all involved, but is by no means mission impossible. I played countless Hb games by this rules and many were greatest experience I got in any Nap War game.
