I was a bit surprised to find out that intercepting cavalry receive the momentum bonus rather than the cavalry that initiated the movement (Living Rules - 11.3.6a). At +2 on a d10 combat roll, that's a significant advantage. Working from the ACW rulebook and finding nothing there I had been awarding both units the +2 if they had both moved at least two hexes etc...
I can see a logic for it and I'm a strong believer in 'the designer had a reason for this' but I'm wondering how it pans out in practice (being a newcomer to this series). Does it reduce the incentive to start a charge unless it's attempted from the rear of the target unit?
Would welcome any comments by more experienced players.
I have checked through the rules postings and haven't found any discussion on this, apologies if I've missed it.
The rule is quiet intentional as it captures part of the risks of cavalry on cavalry combat, and captures the lack of coordination between regiments that was often the case of the era. It forces the player to uses a series of charges, not one general charge. The higher morale cavalry have real advantages. For example, at Edgehill, Prince Rupert's 8 morale cavalry are difficult for Parliament's 6 morale regiments. The 6 morale units are more likely to fail an interception attempt and fall victim to a Charge by one of Rupert's regiments, the morale differential and momentum is hard to defend against.
I put a detailed overview of tactics and techniques in game terms in the following games. I believe I shared that here and /or at Consimworld.
