We can take'em Boys! And some day Osprey will make a book about us titled "Meade's Marauders" or "Gibbons Grenadiers" or "Stonewall's Stompers" or...something.
How NOT to attack in a wargame - or reality!
"Wargaming: An Introduction" detailed tactical and
mechanic analysis
Game Mechanics &
Tactical Analysis: The mechanics of
these rules are pretty simple - the impact on game tactics and how the Union
and Confederate sides fight is not immediately obvious, however, just like with
many other rules. They directly affect what tactics generally work best for both
sides. IF one uses the entire set of rules, as recommended [Mr. T’s “quite
English” style never insists on anything!] then there’s definitely a totality
that creates an overall differentiation between the Union and the Confederacy.
Is it a sweeping generalization? Of course! There’s really no
problem with that since ALL social science and war studies today are based upon
just that, sweeping generalizations.
Yes, there’ll be about 500 exceptions that people can pick out of
history. But we’re talking more to the
5,000 occurrences that make the rule.
BLUF: Shooting is the main tactic, and favors a standing defender. Units either shoot or move. A round of Infantry
Fire results in Morale checks at the second Fire, on average; chance to pass is
33% on average with a failure being a full move to the rear. Assuming a
failure, the opposition may then advance, gaining ground if needed.
Attackers can benefit from preparatory cannon fire; inflicting even just 1-2 Hits removes the “one
more shooting round advantage” a standing defender has over the attacker.
Obviously, a second supporting attacking unit can do the same.
Charges are best executed into the flanks of units exposed by the retreat of their friends from
enemy shooting; an advance can get the right angle in one turn. Charges on the
front of a Target Unit require the attacker to pass a morale check [again,
average of 33% pass rate] but there’s no morale check required to charge a
flank. Also, an advantage in bases is needed as there’s no dice bonus in
Hand-to-hand for attacking the flank or rear, so you need 3-4 bases to the
defender’s 2-3 bases at least, or an additional charging Unit.
Summary: Good tactics with this
game involve an attacker using artillery support to weaken a defending unit - or
two - with 2-4 hits each. A point of attack should be made against a defending
Unit where even just one additional attacking infantry Unit can fire at it.
This should result in the defender retreating a full move, exposing the flanks
of its neighbors in the battle line, who may then be charged on their flank [or
retreat, losing two rounds of shooting or so], and if they’ve even one less
base the attacker should win.
Infantry Shooting and Morale
Mechanics.
Some math and other
calculations this summary is based upon.
- Shooting range is 16cm and Movement is 8cm for
Infantry, so an Infantry move is 1/2 of shooting range.
- Units may only move OR shoot in their turn, not both.
- Retreat from a morale failure caused by stand loss is a
full move, 8cm.
- Rallying back a stand is only possible if one cannot be
shot at by Infantry [or dismtd cavalry].
- Morale check due to stand loss is one worse than to
rally back a stand on a D6 [most
rules have it the other way around, I think]: Elite are a 4+/3+,
Average are 5+/4+, and Militia are 6+/5+, so a Unit is 16.7% more likely
to “rally a stand loss” than “hold under effective fire that resulted in a
stand loss”.
So an Attacker using a shooting strategy v. a Defender prepared and facing it
goes like this:
- Attacker moves
within 16cm of the Defender, between >8-16cm.
- Defender fires
at advancing Attacker, and will always get in the first shot if standing.
- Defender fires
- rolling 4 dice for a 3+ gives about 2.5 hits a turn. With Average dice,
the Defender will inflict 2-3 Hits, not enough to cause a morale
check.
- Attacker will
now fire in his next turn, also inflicting 2-3 hits, not enough for a
morale check [but it should be noted that it is possible for either to
inflict 4 hits and a stand loss and morale check on the other in every exchange
of fire between full-strength Units, so Artillery knocking off just one
stand in preparation for an attack can make a big difference!]. So
with Average dice...
- The Defender will fire
again and cause 2-3 hits and a stand loss. An Attacker with
average morale needs a 5+ or 33% to pass the effective fire of the Defender at
the end of the Defender's turn during the Morale Phase. On average, the Attacker will
fail and retreat 8cm back out of the Defender's shooting
range.
- On the Attacker's turn,
the first Phase is Rallying, which requires that no Defending Infantry
or Dsmtd Cavalry can shoot at this Attacker [not
that they do] and that this Attacker not
move during his turn. So the Attacker has a
choice - to advance back into the Defender's fire
with three stands [75% as effective as the Defender]
or attempt to rally and stay in place for the turn. If
the latter, the Attacker needs a 4+ to rally back the stand loss [a 50%
chance].
Given the above, the
ideal situation for the Attacker is to engage the Defender with even just one extra unit that is ready to move up, with all
four stands, and engage the Defending Unit
that has taken 2-3 Hits in the preceding exchange of fire from which the Attacking Unit retreated. Alternative
[or perhaps best together] is to use Artillery fire to knock off a few extra
hits, resulting in Hit parity between the attacker and defending Unit.
This back and forth of retreats under fire and rallying back, and deciding when
to return to the fray, is of course provided a lot of friction through morale.
Any Unit taking fire from 2-3 enemy Units may easily take 5-10 Hits resulting in
the loss of a stand or two. If the Unit passes the morale checks taken at the
end of the enemy turn, he is almost in more trouble than if he failed them! It
is harder to voluntarily retreat from the enemy than to be forced, as one only
has a 4cm move if one turns around.
This means that if you want to Engage the enemy in a firepower contest, you
almost certainly need an extra unit or two and some artillery support, even
just 1 gun makes a difference, two a BIG difference. You then advance to about
14cm and open fire, this gives you the option to voluntarily retreat 4cm if
needed as well as be forced back 8cm. In both retreat options, you next turn
starts with you making rally attempts which you should definitely do! As you
regain lost stands, you also have to keep the enemy more than 16cm away, out of
possible shooting range, OR screen your rallying unit[s] with a fresh spare
regiment.
Charging and the Morale Mechanics.
Given the 2-1 ratio of
Firing Range to Movement, plus the free shot the defender gets when charged
FRONTALLY, it is impossible to enter HtH without being shot at thrice for foot [and
twice for mounted]. The likely result for Infantry is 1-2 morale checks for 1-2
stands lost, plus a third check to Charge home. The math works out something
like this:
Passing Roll 1
Check 2 Checks 3 Checks
6+ [Militia] 1/6 1/36 1/216 [Hail Mary…]
5+ [Average] 1/3 1/9 1/27 [good
improvement, bad plan]
4+ [Elite] 1/2 1/4 1/8 [hopeful, but not likely]
3+ [Elite +Gen] 2/3-66% 4/9-44% 8/27-30% [doesn’t get better, unfortunately]
So without amazing
extremes of Lottery Winning Luck, we’re looking at a defender rolling low on
their shots and only causing one check for stand loss followed by a second
check to charge home, or a 44% chance, not even 50-50. That’s charging with an
Elite Unit lead by a charismatic general. Clearly, if we are going to attack
through charging, we’re going to have to improve our odds.
One way is to punish
defending Units through superior firepower. This might be accomplished through
concentrated artillery or just one extra unit overlapping. A defending unit
that has managed to pass its morale and stick around will be firing with 3 or 2
dice depending. Just what are the Artillery
shooting odds?
Unit
Size 4 stands 3 stands 2 stands 1
stand
Infantry, 3+ to Hit 2.67 Hits 2 Hits 1.33
Hits 0.67 Hits
Napoleons, 4+ to Hit
Long Range, 1 Dice 2 Hits 1.5
Hits 1.0 Hit 0.5 Hit
Short Range, 2 Dice 4 Hits 3
Hits 2 Hits 1 Hit
Clearly, if we can
advance against a Defending unit with 3 - or even better 2 - stands, our
chances of closing in for a charge drastically rise since it takes 4 Hits to
remove a base and cause a Morale Check. With just one stand missing, a defender
drops from 8 Hits and two bases shot off to 6 Hits and one base shot off. With
two stands left, it has a 50% chance of failing to cause a check at all. So
it’s clear that a successful charge relies on attacking defenders who’ve lost a
base or two.
Additionally, if a
defending line of Units has a Unit retreat, the resulting gap may allow a flank attack at one of the remaining
defenders. This should significantly increase the chance of success as it avoids
defensive fire [being out of their fire arc] and does not require a Morale
Check of the Charging Unit. It is also advantageous to advance against units
that retreat anyway, since they cannot rally with an enemy infantry [or
dismounted cavalry] in firing range.
Thus the key to charges in this game is to initiate an attack with
firepower, then take advantage of retreating defenders to exploit gaps in the
line while denying them chances to rally. A
Mounted cavalry Unit would seem to be ideal, but how often does that happen!?
Between Artillery and long shooting ranges, it’s nearly impossible to deliver
Cavalry into a charge successfully in most ACW games.
All of which clearly
illustrates how a few simple mechanics can result in pushing – without forcing
– the player to use what the designer believes to be historically accurate
methods to play, fight and win, without miring them in piles of charts and
tables and forcing them to do lots of math [which is still useful to figure
one’s chances of success, however!]. I hope this shows how simple but not
simplistic rules, and good design, promotes both history and mental acuity, and
NT’s ACW offering seems to have both – Happy Gaming!
