Fog of War

Carl von Clausewitz painted by Karl Wilhelm Wach. Credit Wikipedia. Click to enlarge.

Carl von Clausewitz in his On War wrote, “War is the realm of uncertainty; three quarters of the factors on which action in war is based are wrapped in a fog of greater or lesser uncertainty. A sensitive and discriminating judgment is called for; a skilled intelligence to scent out the truth.” Though Clausewitz never specifically wrote the phrase ‘Fog of War’, the above quote is the source of the term which we abbreviate today as FoW. FoW in the 18th and 19th centuries (the era specifically covered by General Staff: Black Powder) was especially problematic because of the lack of modern day battlefield information gathering techniques such as drones, aircraft and satellites (yes, hot air balloons were used in the Civil War but their actual value during combat was minimal).

General Staff is a wargame that can simulate the FoW experienced by an 18th or 19th century commander and his staff. We use the qualifier ‘can simulate’ because General Staff can run in five different ‘modes’:

  • Game mode / No Fog of War
  • Game mode / Partial Fog of War
  • Simulation mode / No Fog of War
  • Simulation mode / Partial Fog of War
  • Simulation mode / Complete Fog of War

Game mode came from a strong desire to create an introductory wargame, with simplified rules, played on historical accurate battlefield maps that could be used to introduce novices to wargaming.

Antietam, 0600, Game Mode. Reinforcements shown. Click to enlarge.

In the above two screen shots from General Staff you can clearly see the differences between Simulation and Game mode. In Simulation mode a unit’s exact strength in men, leadership value, morale value, experience value, number of volleys and the time it will take for a courier to travel from it’s commander’s HQ to the unit are displayed and tracked. In Game Mode, unit strength is represented by the number of icons (1 – 4) and leadership, morale, experience, and ammunition are not tracked. Units are moved directly by the player and there are no HQ units. In Simulation Mode, orders are given from the commanding HQ down to the subordinate commander’s HQ and then to the actual unit. The leadership value of each HQ effects how long the orders will be delayed on the way.

Little Bighorn, Simulation Mode, Complete Fog of War (from the commander’s perspective). Screen shot. Click to enlarge.

In the above screen shot, we see ‘Complete Fog of War’; only what the commander can see of the battlefield is displayed. In this case, this is what Colonel George Custer could see at this time.  Just as in real life, in Complete Fog of War the commander receives dispatches from his troops about what they have observed; but this information is often stale and outdated by the time it arrives.

Little Bighorn, Simulation Mode, Partial Fog of War. This displays what all Blue forces can observe. Click to enlarge.

In the above screen shot Partial Fog of War is displayed. This is the sum of what is observable by all units (in this case, the Blue force). This is historically inaccurate for the 19th century and is included as an option because, frankly, users may want it and, programmatically, it was an easy feature to add. Throughout the development of General Staff we have consistently offered the users every conceivable option we can think of. That is also why we have included the option of, “No Fog o War,” with every unit visible on the battlefield. It’s an option and some users may want it.

We have experimented with different ways of displaying ‘stale’ unit information including this method, below:

An example of how units that are not directly visible to HQ are displayed. The longer that a unit remains unobserved, the fainter it becomes. (Click to enlarge.)

We are now experimenting with overlays.

Introducing a New Generation to Wargames

My childhood friend, Carl Hoffman, introduced me to Avalon Hill wargames. Carl is now a history teacher.

It was my good friend, Carl Hoffman, who lived across the street when I was about 10, who introduced me to Avalon Hill (AH) wargames. The AH wargames of the 1960s were perfectly suited to spark a kid’s imagination. The rules were easy to understand (four pages, big type, with illustrations explaining movement and combat), the Combat Results Table (CRT) was straightforward (and taught us to calculate ratios, too), and we could refight Gettysburg or Waterloo on a rainy afternoon. We learned history (Carl became a history teacher) and problem solving (I became a computer scientist). I’m sure many of us had similar experiences forty or fifty years ago.

For a long time I’ve felt that there is a need for similar ‘introductory wargames’ to engage the next generation of grognards and wargamers. While the hardcore aficionados want more complex and detailed games I’ve also understood that we needed simple, introductory games, to entice a new generation.  From the beginning, I have always had a simpler wargame embedded inside of General Staff. Specifically, if we remove all the layers of historical simulation, what remains is a simple introductory wargame.

The Layers of Historical Simulation in General Staff

Each layer of historical simulation can be turned on or off when playing a General Staff scenario. The more options you add, the more historically accurate the simulation becomes. The options are:

  1. Unit strength
    1. Unit strength is a value from 1 – 4 with units being reduced in steps.
    2. Unit strength is the actual historic number of troops and every individual casualty is tracked.
  2. Combat resolution
    1. Simple Combat Resolution Table like the old AH CRT.
    2. Complex Combat Resolution Equation taking into effect morale, experience, leadership, terrain, and elevation.
  3. Moving units
    1. Units are moved directly by the player.
    2. Orders to move units are issued down a chain of command from the top HQ to the subordinate HQ via couriers and the rapidity with which the orders are executed depends on the Leadership Value of the subordinate HQ and subordinate units.
  4. Fog of War (FoW)
    1. No Fog of War. The entire map is visible and all units (friend and foe) are displayed on it.
    2. Partial FoW. The entire map is displayed and the sum of what all friendly units can see is displayed.
    3. Complete FoW. You see only what the commander can see from his HQ and nothing else. All unit positions not directly observable are updated via couriers and are frequently no longer accurate by the time the courier arrives.

So, at it’s most complex (let’s call this a Historical Accuracy level of 100%) this is what the player commanding the Army of the Potomac (Blue) would see (what General George McClellan could actually see through his telescope on the lawn of the Pry House on the morning of September 17, 1862):

Antietam from the perspective of General George B. McClellan at the Pry House on the east bank of the Antietam Creek. This is complete Fog of War and the highest level of historical accuracy. Screen shot. Click to enlarge.

And, interestingly, this view of what McClellan could see is confirmed in The U. S. Army War College Guide to the Battle of Antietam and The Maryland Campaign of 1862 edited by Jay Luvaas and Harold W. Nelson.”General McClellan and his headquarters staff observed the battle from the lawn of the Pry House… Through a telescope mounted on stakes he enjoyed a panorama view of the fighting… He could see Richardson’s division break through the Confederate position at the Bloody Lane. He could not, however, follow the movements of the First and the Twelfth Corps once they disappeared into the East Woods, which masked the fight for the Cornfield, nor did he witness the attempts to seize Burnside’s bridge to the south because  the view from the Pry House was blocked by trees and high ground.” – p. 119.

So, the above is the 100% historically accurate view of the battle of Antietam from McClellan’s Headquarters. This is the ‘introductory’ view:

Antietam in ‘Introductory’ mode. Note that unit strengths are represented by one to four icons. Also note the lack of HQs. Screen shot. Click to enlarge.

I first saw the concept of ‘unit steps’ in Jim Dunnigan’s Avalon Hill classic, 1914 and I’m shamelessly using it here. I very much like the simplicity of this system: as units take casualties, they are reduced, in steps, from four icons, to three, to two, etc. I also very much like the idea that this is not an abstraction of the battle of Antietam (or Little Bighorn, or Quate Bras, etc.) but the actual units in their actual locations. This fulfills my requirements for an introductory wargame: historic, teaches tactics and problem solving, easy to play, simple rules, quick to learn and quick to play (I would think a game could easily be played in less than an hour).

Here are some more General Staff scenarios in ‘introductory mode’:

I could use your help! Announcing a ‘name the mode’ contest!

From ‘The American Kriegsspiel. Clicking on this image will take you to the Grogheads.com article on William Livermore’s American Kriegsspiel.

I originally called ‘introductory’ mode, ‘Kriegsspiel’ mode because I was reminded of the maps and blocks that Kriegsspiel uses. However, I pretty quickly received some emails from the Kriegsspiel community complaining – and rightfully so – that Kriegsspiel isn’t an introductory game. Absolutely! And if you’ve ever taken a look at the original rule books and tables you would agree, too.

So, here’s my problem (and how YOU can help): I need a new phrase to replace ‘Kriegsspiel mode’. I’ve been using ‘Introductory mode’ but I just don’t like it. I really need a new name for this version. I’m open to any suggestions. How about a completely made up word? ‘Stratego’ would be great if it hadn’t already been used. So, I’m announcing a contest to ‘name this mode’. The winner will receive 2 General Staff coffee mugs. Please email me (Ezra@RiverviewAI.com) with you suggestions. Thank you for your help!

How Will You Play General Staff?

Every wargame that I’ve designed allows the user to adjust important variables such as leadership and morale and how they affect combat. Usually included is the ability to design your own armies, maps and scenarios as well. However, with the General Staff Wargaming System we’ve added a new feature: the ability to control the realism level before playing a scenario.

The General Staff Wargame has two basic levels of play:

Simulation mode uses HQ units and a chain of command that passes orders down from the General HQ to the sub-commander to the individual unit. How fast the unit responds to the orders are affected by the distance that the courier must travel and the Leadership Value of the HQs.  Simulation mode also employs a more detailed combat resolution model and tracks the actual number of troops in every unit.

An example of Simulation Mode: the path (red line) and time (16 minutes) it will take for a courier to travel from JEB Stuart’s HQ to Munford’s cavalry with orders. Click to enlarge.

Kriegsspiel mode does not have HQ units and friendly units are moved directly and immediately (no transmission of orders via couriers). The combat resolution model is simpler and units have a value of 1-4 displayed by the number of unit icons on the map.

Antietam in Kriegsspiel mode. Notice that there are no HQ units (so no couriers to deliver orders) and units are represented by 1-4 icons. Units in column have a ‘tail’ that indicates the unit strength. Click to enlarge.

In addition to the two game modes (Simulation and Kriegsspiel) there are three Scenario Options:

Order of Battle (OOB) displayed / not displayed. Enemy units with known positions appear dark; enemy units ‘on the map’ but with unknown locations appear grayed out. This, of course, gives the user complete knowledge of the enemy’s OOB and, more importantly, knows when units from certain formations are not directly observable.

A mock up of how the Order of Battle option will appear (note this image was created from screen captures of the Scenario Editor and the Sand Box). Click to enlarge

Only friendly units directly observed by the General HQ are displayed. All other friendly units fade at their last known location. Couriers bring in unit location updates, but they are outdated by the time they arrive.

Only enemy units directly observed by the General HQ are displayed. All other enemy units fade at their last known location. Couriers bring in unit location updates, but they are outdated by the time they arrive.

If both of these above options are selected (only friendly and enemy units that are directly observable by your commanding General HQ) you will be simulating the Fog of War that field commanders of the age of gunpowder experienced.

We would like to hear from you and get your opinion on what realism features you will use in General Staff:

“What Ifs” at Little Bighorn

I‘m used to learning a lot when researching a battle but nothing prepared me for the ‘what ifs’ of Little Bighorn. My doctorate is in computer science but I have been an American Civil War buff since I was about five years old. I’m very familiar with brevet Major General George Armstrong Custer’s achievements during the Appomattox campaign where he commanded a division that smashed Pickett’s right flank at Five Forks. I knew that after the war Custer returned to his previous  rank in the U. S. Army of Lt. Colonel, that he fell under a cloud with U. S. Grant, was stripped of his command, and had to beg for it back from President Grant, himself, at the White House.

And, of course, I knew of the debacle at the Little Bighorn.

After I wrote UMS, the first computer wargame construction system, users began to send me Little Bighorn scenarios that included Gatling guns. I assumed that these were science fiction ‘what if’ scenarios. such as a story I read back in the ’60s about what if Civil War units had automatic weapons from the future. But, recently, while reading Stephen Ambrose’s Crazy Horse and Custer I learned that General Alfred Terry, Custer’s superior and the commander of the expedition, had indeed offered Custer not just three Gatling Guns (manned by troops from the 20th Infantry 1)The Guns Custer Left Behind; Historynet
https://www.historynet.com/guns-custer-left-behind-burden.htm
) but four extra troops from the 2nd U. S. Cavalry.  Custer turned down Terry’s offer of reinforcements and more firepower with these infamous words:

“The Seventh can handle anything it meets.” – Custer to Terry

Screen capture of the Order of Battle of the 7th US Cavalry with the addition of 3 Gatling guns and 4 companies of the 2nd US Cavalry. Click to enlarge.

As for the battle of Little Bighorn, itself, I didn’t know much more than the broad outline that Custer and his command were killed to the last man by an overwhelming number of Native American warriors (this, of course, wasn’t correct as members of Reno’s and Benteen’s columns survived). Custer, himself, was the text book image of hubris and became the butt of late night comedians and humorous pop songs. But the reality turned out to be much more complex and nuanced.

Custer had a reputation of being dashing, headstrong, and gallant; the iconic description of a cavalry commander. The traditional narrative of the disastrous battle of Little Bighorn is that Custer impulsively attacked a vastly superior enemy force; possibly propelled by a belief that Native American warriors were no match for organized cavalry armed with 45-70 trap door carbines. Indeed, Napoleon’s maxim was that, “twenty or more European soldiers armed with the best weapons could take on fifty or even a hundred natives, because of European discipline, training and fire control.” 2)Crazy Horse and Custer” p. 425 Stephen Ambrose To make matters worse, Custer had pushed the 7th mercilessly and by the time they arrived at the battlefield both men and horses were exhausted.

Custer’s plan of attack is also widely condemned as overly optimistic. He split his command of 616 officers and enlisted men of the 7th cavalry into three battalions. If the four companies of 2nd Cavalry had come along, Custer’s force would be 30% larger.3)Ibid The main force led by himself would be the right flanking column, Reno would have the left flanking attack column and Benteen and the pack train would be in the middle.  Custer also drastically underestimated the Native American force at about 1,500.

In theory, Custer’s plan of attack wasn’t that bad:

  • If Custer was up against a force that was only two or three times his size and
  • If Reno had pressed home his attack drawing the Native American warriors east toward him and
  • If Custer had been able to cross the Little Bighorn above the Native American camp and
  • If Custer had been able to attack the village while the warriors were engaged with Reno

Custer might have, indeed, had a great victory that would have propelled him to the US Presidency (as he had hoped). But none of these suppositions were correct.

Not the Order of Battle of the 7th Cavalry (with attached units of the 2nd Cavalry and Gatling guns) on the left. Units are positioned by clicking and dragging them from the Order of Battle Table on the left onto the map. Click to enlarge.

So, the question remains: what value for Leadership would you give to Custer?

By the way, there will be three separate Little Bighorn scenarios for the General Staff Wargaming System: historically accurate Order of Battle for the 7th Cavalry, the 7th Cavalry plus four companies of the 2nd US Cavalry and 7th Cavalry plus four companies of the 2nd US Cavalry and 3 Gatling guns.

Using General Staff to Create a Simulation of the Battle of Isandlwana (January 22, 1879)

We recently asked you for your favorite 18th and 19th century (‘Age of Gunpowder’) battles to be included free for early backers of General Staff (see this link). We don’t want to spoil any surprises, but the Battle of Isandlwana was one of the top vote-getters.

Screen shot of the General Staff Scenario Design Module showing how to edit specific unit type versus unit type combat equations. In this example Blue Light Infantry (Zulu regiments) have been adjusted downward. Click to enlarge.

The Battle of Isandlwana is an especially challenging scenario to simulate because of the difference in technology (the British were armed with Martini-Henry breech-loading rifles while the Zulu warriors carried the traditional assegai iron spears and cow-hide shields). Yet, there are ‘Light Infantry’ unit types in both the Red and Blue forces, but clearly there is a very big difference between the Red (British) Light Infantry and the Blue (Zulu) Light Infantry units.

General Staff, which is based on the UMS Wargaming System, has the ability to adjust a unit’s combat firepower versus other unit types (see the above screen capture). In the above image we have set Blue’s Light Infantry (Zulu regiments) with a lower Attack Multiplier representing the Zulu troops lack of muskets and rifles. This matrix is available from the General Staff Scenario Design Module.

Screen capture of the British army Order of Battle for Isandlwana . Click to enlarge.

In the above screen capture from the General Staff Army Design Module we see a portion of the British Order of Battle at Isandlwana. The question is: what should Leadership, Morale and Efficiency be set for each of these units? How good were British commanders? What was the morale of native troops? How efficient were they? We would love to hear your comments.
