"battlefield commo" Topic

A long discussion with GROK about how wach side communicated on the battlefield. Also a good example of develoiping rules with the help of an AI:

How did US cavalry in the plains wars communicate on the battlefield. I assume trumpet calls were the most important, and a bugler would stay close to the commander. Were guidons still carried and did they serve a tactical role as a signal (or at least to locate the boss)? But bugle calls would have everyone in the troop doing the same thing? As a lieutenant going through Infantry Officer Basic (Fort Benning 1971) we were hammered to keep the platoon together no matter what. A troop was a bit larger, but did it ever subdivide? and if so how did the separate parts communicate? (Of course that was part of what happened to Custer at LBH!)

Yes, trumpet (or bugle) calls were the primary—and often only reliable—method of battlefield communication for US Cavalry during the Plains/Indian Wars era (roughly 1865–1890, especially the northern plains fights against the Sioux, Cheyenne, and allies). A dedicated bugler (sometimes called a trumpeter) was assigned to each troop and rode right with the commander (usually the captain, or a lieutenant in his absence). This setup carried straight over from late Civil War practices and was formalized in the post-war manuals.

The 1873 Cavalry Tactics manual (assimilated to infantry and artillery tactics under Emory Upton) and the standardized bugle calls issued in 1867 kept the system the same as the late 1860s/early 1870s. Calls like "To Horse," "Forward," "Charge," "Rally," "Cease Firing," "Retreat," and many others let the commander direct the entire troop at once. In the open northern plains, sound carried well (better than in the brushy southwest of the pre-1860 Comanche fights), but dust, wind, gunfire, and distance could still garble things—exactly why the bugler had to stay glued to the boss.
Guidons were absolutely still carried and had a real tactical role. Each troop had its own swallow-tail guidon (red-over-white in the 1870s, with the troop letter). The guidon bearer rode near the commander and bugler. In the chaos of a mounted charge, dust cloud, or after a melee, troopers were trained to "rally on the guidon." It was both a visual beacon to locate "the boss" and the physical rally point. Reenactors and period accounts repeatedly note troopers reforming on their guidon after a charge or when the unit got scattered. In a tabletop wargame, this makes the guidon a perfect marker for command radius, rally mechanics, or cohesion bonuses—very different from the more ad-hoc Texas Ranger/Comanche fights where there were no standardized unit flags.

Bugle calls did drive the whole troop (or platoon) to do the same thing at the same time. That was the whole point of the system—no radios, so one clear auditory command kept everyone synchronized. Officers and NCOs could layer verbal commands once the unit was close, but the bugle was the "radio net" for the troop.

Yes, troops did subdivide, and that is where things got interesting (and risky) for wargame design. A typical field-strength troop in the 1870s was 40–70 men, organized into two or four platoons (sometimes called sections or sets of fours). The smallest maneuver element was usually the platoon, led by a lieutenant or senior NCO. When dismounted (very common in Indian fights because of the repeating carbines), every fourth man became a horseholder, freeing three-quarters of the troop to fight on foot in a skirmish line. Platoons or even smaller groups could peel off for flanking, skirmishing, or holding ground.

How did the separate parts communicate?

• The main bugle call still applied to the whole troop (or the commander could send a subordinate bugler/messenger).
• Lieutenants used voice, hand signals, or example ("follow me").
• Orderlies and trumpeters doubled as runners between subunits or battalions.
• Once separated by more than a couple hundred yards, coordination collapsed fast—exactly what happened to Custer at Little Bighorn. He split the regiment into three battalions (Reno 3 troops, Benteen 3 troops, Custer 5 troops) plus the pack train. Within Custer's wing the companies further fragmented under lieutenants, and the lack of reliable communication between the separated forces was a major factor in the disaster. Your 1971 Infantry Officer Basic emphasis on "keep the platoon together no matter what" was exactly the doctrine they tried to follow—but the open plains, fast-moving Indian warriors, and sheer size of some villages made it hard.

For your tabletop adaptation of Cynthia Ann's War rules to the northern plains post-Civil War period, the big relevant differences are:

• Much more standardized, drill-based control (bugle + guidon) instead of the looser Ranger/Comanche raiding style.
• Troop-level bugle calls create a natural "one order per troop per turn" mechanic, with guidons as visible command/rally markers.
• Platoon subdivision is possible and historically accurate, but you can build in friction: extra command cost, cohesion penalties, or "lost order" chance if the subunit is out of bugle/guidon range or the commander is busy.
• Open-plains terrain favors long bugle audibility and guidon visibility, but dust/wind can still create "fog of war" for signals.
• Dismounted fighting with horseholders becomes a key tactical choice—something less emphasized in the pre-1860 southwest fights.

This setup lets you keep the spirit of your existing rules while adding period flavor: buglers and guidons become literal game pieces that affect activation, rally, and command-and-control. The Custer example is perfect for showing what happens when you push subdivision too far without secure comms. If you want specific bugle-call lists, platoon organization diagrams from the 1873 manual, or ideas for how to codify "rally on the guidon" as a mechanic, just say the word!

Okay, good, and helpful. I'm goin to assume my pre-1860 rangers (within each maneuver element) ride closely enough together to hear orders and see hand signals, but the various elements in a larger fight will be hard to coordinate -- which will basically be the game for the player.

Sounds like a rock-solid plan for your adaptation — keeping the pre-1860 Texas Rangers' "tight within the element, chaotic between elements" feel as the core player challenge is exactly how Cynthia Ann's War already models frontier fighting, and it translates beautifully to the northern plains post-Civil War.

Quick confirmation on your Rangers assumption (pre-1860 base)

Yes, that matches the historical reality of Ranger/Volunteer companies in the Comanche wars. A typical maneuver element (say, a 20–40 man detachment or "company" under one captain or lieutenant) stayed bunched up on the move or in the charge so the leader could shout orders, use hand signals, or just be seen and followed. They didn't have buglers or standardized flags; coordination was personal and visual/auditory only while the group stayed within easy shouting distance (maybe 50–100 yards in the Texas brush and dust). Once you had multiple elements in a bigger scrap — different companies, Ranger units plus militia, or allied Indian scouts — the player's headache kicked in: riders had to be detached as couriers, pre-planned signals (a hat waved on a lance, a shot in the air) were unreliable, and the open-but-broken terrain often turned a "coordinated" attack into several semi-independent little battles. That friction is pure game gold, and you're smart to keep it as the central tension.

How the post-CW cavalry vs. Sioux period differs — and how to tweak your rules for it

The northern-plains cavalry (especially 1865–1890 against the Sioux, Cheyenne, etc.) gives you a natural evolution of the same system without breaking your existing framework. The big relevant differences for tabletop:

• Within a maneuver element (now usually a full troop of ~40–70 men): Much tighter, more reliable control than Ranger groups. The bugler stayed glued to the captain (or senior lieutenant), and one clear trumpet call could swing the whole troop from "walk" to "gallop" to "dismount and skirmish" in seconds. The guidon (that red-over-white swallow-tail flag) was the visual anchor — troopers were drilled to "rally on the guidon" after a charge or when dust scattered them. So in your rules you can give a cavalry troop a smoother "internal activation" than a Ranger element: maybe one automatic or low-cost order per turn as long as the commander + bugler + guidon figure are together and not suppressed. Rangers keep the slightly more friction-heavy voice/hand-signal mechanic you already have.

• Between elements (multiple troops, battalions, or split platoons): Still exactly the hard-to-coordinate mess you want as the player's game. Even with bugles, once you split a regiment (like Custer did at Little Bighorn) or send platoons off on flanks, communication drops back to riders/messengers, hand signals at distance, or just hope. Open plains helped sound carry a bit farther than Texas brush, but dust clouds, wind, and gunfire still garbled everything. You can port your existing inter-element penalties straight over — maybe just flavor them differently: a cavalry "orderly" figure instead of a Ranger courier, or a small delay table that reflects "waiting for the bugle to be heard and answered."

• Subdivision option (the Custer risk): Cavalry troops could break into two platoons (or even sets of fours) for flanking or dismounted fire, but doctrine hammered "keep the unit together." In game terms this becomes a classic risk-reward choice: splitting gives you more tactical flexibility (extra activation dice? better coverage of the table?) but instantly ramps up your coordination friction exactly like the multi-element problem you already have. Guidons and buglers can become literal game markers — if the platoon loses sight of its guidon or the bugler is downed, cohesion drops hard.

• Sioux side contrast (for balance): Their communication stayed even looser — fast pony messengers, war cries, hand signals, or pre-arranged feints — but with superb individual warrior initiative. You can keep your existing Comanche-style "decentralized activation" rules almost unchanged; the Plains warriors just feel more fluid and less "drilled" than the bluecoats.

Suggested light rule tweaks to layer onto Cynthia Ann's War
• Cavalry troop activation: One free bugle command per turn while the command group (officer + bugler + guidon) is intact and within X inches.
• Ranger element activation: Still requires the leader figure to be close and roll or spend a command point (your existing mechanic).
• Inter-element coordination phase: Same penalty chart you use now, but cavalry gets a small bonus if a messenger reaches the target element (reflecting better-trained orderlies).
• Rally mechanic: Cavalry rallies automatically on the guidon token; Rangers need a successful leader check.
• Terrain note: Northern plains tables can have slightly better signal ranges than your Texas brush setups, but add "dust cloud" markers that block line-of-sight to guidons or muffle bugles on a die roll.

This way the pre-1860 rules stay your foundation, the post-CW period just feels more "professional" inside each troop while the big-picture coordination headache remains the heart of the game — exactly like the historical shift from irregular Rangers to drilled cavalry. Players will still feel the same tension you want, but now with bugle calls and guidons as fun, flavorful tools instead of pure chaos.
If you want me to sketch a sample activation sequence, a short bugle-call reference table for the rules sheet, or ideas for how the Sioux player's looser comms balance the bluecoats, just drop the word. We can dial in the exact mechanics to fit your existing Cynthia Ann's War engine. This is going to be a great adaptation!

Okay, and you anticipated my next question about how the other side communicated. Warriors raised in the same tradition would have a good idea of how to behave in predictable circumstances. And I assume it was routine to keep an eye on the leader, in the same way a good driver today checks the rearview mirror often even while keeping his eyes mostly on the road ahead. But if warriors are skirmishing then they are spread out, and there is dust and noise; was there a way to get everyone to rally around and get a new order? There is, it seems to me, a point at which "distributed leadership" becomes "no leadership" which is "each man does what is right in his own eyes." a hypothetical: Red lance is skirmishing along with a dozen warriors, and sees a Texan turn and bolt for the rear as the ranger captain tries to stop him. Aha! thinks Red Lance, time to charge with my lance and make it redder! But does he just GO and trust the others will see him and join in? That would take enormous courage and confidence or else suicidal indifference. And even if the others in the band see and immediately charge as well, Red lance still has a five second head start and will reach the Texans by himself. Did the Comanche, or the northern tribes, have anything better than personal example to convey a new tactic, when the individual warriors are, if skirmishing, riding separately and at some distance from one another with changes of direction, wheeling, etc?

Perfect — you're zeroing in on exactly what makes Native warrior communication such a rich, high-friction element for your tabletop adaptation. The "keep an eye on the leader like checking the rearview mirror" instinct you described was real and drilled into every Comanche and Sioux/Cheyenne boy from childhood. But when a dozen warriors were skirmishing in the dust and noise — wheeling ponies, loosing arrows or carbine fire, changing direction every few seconds — pure personal example was the primary way to shift tactics. Still, they had better tools than "Red Lance just charges and prays the others notice."

Pre-1860 Comanche base (your existing rules)
Comanche raiding parties and war bands were masters of loose, opportunistic coordination. They relied on:

• Visual cues: Leaders (or ambitious warriors) used lances held high or waved as signals. Mirrors (small trade mirrors or polished metal) could flash from a rise to catch attention across a skirmish line — one captured boy even reported Comanches signaling with mirrors in the 19th century. Hand signals drawn from the widespread Plains sign language let a rider gesture "charge here" or "rally on me" without shouting.

• Auditory cues: War whoops weren't just noise — specific cries or sequences carried meaning (defiant yell to start, mournful wail if things went bad). In unfriendly territory or at night they used animal calls (owl hoots) to regroup scattered warriors. Oral commands and simple pre-planned signals (a hat waved on a lance, a shot in the air) were common.

• Cultural "rearview mirror" training: Every warrior knew the expected play in predictable situations (enemy bolts → exploit it). So Red Lance could just spur forward with his lance, trusting the band would see and swarm in behind him — that kind of individual courage was how you counted coup and built reputation. But in practice a leader or bold warrior often gave the cue first (whistle, cry, or mirror flash), and the rest flowed in naturally.
Smoke signals and stone markers were more for pre-battle or long-range scouting than the heat of a close skirmish. Once the dust flew, it was all visual/auditory + shared tribal instinct.

Post-CW northern plains (Sioux, Cheyenne, etc.) — the evolution for your rules

The Sioux/Cheyenne fights against the cavalry (Rosebud, Little Bighorn, Wolf Mountain) used the same toolkit but scaled up for bigger battles and more warrior societies (Dog Soldiers, etc.). Accounts from both Indian and soldier eyewitnesses show surprisingly effective command even when skirmishing:

• Flags/banners became visible rally points — several chiefs at Little Bighorn each carried a colored flag (red, yellow, white, etc.) that warriors rallied to, exactly like your cavalry guidon but more decentralized. One trooper noted the chiefs "handled their warriors splendidly" with them.

• Mirrors were used deliberately from high ground (Crazy Horse directing the whole fight at Rosebud via mirror flashes).

• Eagle-bone whistles (and captured U.S. bugles) cut through dust and noise — piercing, unmistakable signals that could be blown whi
le riding or even when warriors were out of sight. Soldiers heard them constantly: "We could not see the Indians, but they were signaling all the time with their little bone whistles."

• Voice commands — a powerful chief's cry (sometimes repeated four times) could swing 200+ warriors from one flank to another or order a withdrawal. Two rifle shots at dawn sometimes served as the "open fire" signal.

• Personal example still ruled — but now layered with the above. Red Lance sees the bolting Texan (or cavalryman), blows his whistle or flashes his mirror while charging, and the dozen warriors who have been keeping one eye on him (or the nearest society leader) peel off and join without missing a beat. The five-second head start is real and historically accurate — that's how you earned honors — but the signals minimized the suicidal solo risk.

In short, it never quite collapsed into "each man does what is right in his own eyes" unless the war leader was killed or the band was completely broken. Distributed leadership worked because of lifelong training, shared cultural playbook, and those simple but effective signals. The northern tribes had slightly more formalized warrior-society structures (lances as rank symbols in some bands), so a Dog Soldier subgroup might respond even faster to a whistle than a looser Comanche raiding party — but the difference is small enough that your existing pre-1860 mechanics carry over cleanly.

Wargame tweaks to layer onto Cynthia Ann's War
This gives you natural, flavorful mechanics without rewriting the engine:

• Within a warrior band (your maneuver element): Every band gets a small "signal pool" (1–2 tokens per turn: whistle, mirror flash, or society flag/lance). Spend one to let a subordinate warrior (Red Lance) initiate a new tactic (charge, wheel, rally) and automatically pull in 2–3 nearby figures without extra friction. No token? Pure personal example — he goes alone first, others need a successful "rearview mirror" check (your existing cohesion roll) to follow.

• Skirmish spread + dust/noise: Add a light negative modifier (or random event card) when warriors are >6–8 inches apart or in dust clouds — signals are harder to see/hear, so the "distributed leadership" risk ramps up exactly as you described.

• Rally/new order: A war leader (or bold sub-leader) can use a whistle/mirror as a rally beacon, pulling scattered warriors back faster than a Ranger element could. Northern-plains bands get a tiny bonus if you represent a society lance or captured bugle as a token.

• Cavalry contrast: Bluecoats still have the bugle + guidon for crisp troop-level orders, but your Sioux player now has mirror/whistle/flag tools that feel more fluid and opportunistic — perfect asymmetry. The player's game remains "coordinating the elements is hard," but the Indian side gets more individual-hero moments that can snowball into a sudden swarm.

Your hypothetical Red Lance moment becomes a classic player choice: risk the solo charge for glory (and possible coup-counting bonus) or burn a signal token to bring the band with him instantly. That tension — courage vs. coordination — will feel exactly like the historical fights while staying true to your pre-1860 foundation.

If you want a one-page "Plains Warrior Signals" reference chart (whistle = charge here, mirror = flank left, etc.) or ideas for how warrior-society lances could act as mini-guidons for the northern tribes, just say the word. This adaptation is going to sing on the table.

Plains Warrior Signals Reference Sheet (For Cynthia Ann's War adaptation – Comanche pre-1860 base + northern-plains Sioux/Cheyenne post-CW evolution)

Use this one-page chart exactly as written or drop it straight into your rules booklet. It slots onto your existing maneuver-element activation system without changing the core engine. Every warrior band (your basic unit) starts the turn with 1 Signal Token (Comanche) or 2 Signal Tokens (northern tribes – they had more formalized warrior societies). Tokens are spent to trigger signals. No token? Fall back to pure "personal example" (the risky Red Lance solo charge you described).

How Signals Work in Play

• Cost: Spend 1 token to give a signal.
• Range: Any friendly warrior in the same band who can see the signaler (normally 8–12 inches on the table; reduce to 6 inches in dust/smoke).
• Effect: The signaled warriors automatically join the new action without a cohesion check. They move/charge/fire as a group.
• Personal Example fallback: If no token is spent, the bold warrior (Red Lance) goes alone. Others may follow only after a successful "rearview mirror" roll (your existing cohesion mechanic). This creates the exact 5-second head-start tension you want.
• Northern-plains bonus: Sioux/Cheyenne bands treat society lances or captured bugles as mini-guidons – place a small token with the leader; any warrior within 6 inches automatically sees it as a rally point (no roll needed).
Common Signals Table
Signal Type How It Looks / Sounds Meaning / Tactical Use Game Effect (when token spent) Historical Note (Comanche vs. Northern)

Eagle-Bone Whistle (primary auditory) High, piercing trill or short blasts while riding "Charge here!" or "Follow me!" Whole band charges or wheels as one; +1 melee bonus if striking first Both tribes; northern warriors used captured U.S. bugles too

Mirror Flash Small trade mirror or polished metal flashed from a rise or while circling "Flank left/right" or "Rally on me" Band shifts direction or pulls back to leader; ignores 1 dust penalty Common to both; Crazy Horse used this at Rosebud for whole-battle control

Lance / Society Flag Wave Lance or colored cloth (red/yellow/white) held high and swept in an arc "Skirmish line here" or "New target" Band forms skirmish line or switches focus; counts as "distributed leadership" without collapse Northern tribes stronger here (Dog Soldiers carried society lances as rank symbols); Comanche used decorated lances more for coup
War Whoop Sequence Specific cry pattern (short-long-short = attack; long wail = withdraw) Pre-arranged "go" or "break off" Instant activation for one action; can be heard even if line-of-sight blocked Both; Comanche favored night owl-hoots for regrouping
Hand Signals (Plains Sign Language) One-handed gestures while riding (point + circle = rally, etc.) "Dismount and fire" or "Watch the ponies" Band performs dismounted skirmish or horse-holder drill without delay Universal; every warrior knew these from childhood

Two Rifle Shots Two quick carbine or revolver shots in the air "Open fire / commence attack" Band begins coordinated volley; removes 1 turn of hesitation

Northern plains favorite at Little Bighorn dawn attacks
Captured Bugle U.S. Army bugle blown with Indian flourish "Do what the bluecoats do" (charge, rally, etc.) Mimics one cavalry bugle call for the band Northern tribes only (post-1865); huge psychological edge
Special Rules & Flavor for Your Table

• Dust & Noise Penalty: If the band is spread >8 inches or in a dust cloud, roll 1d6 when spending a token: 1–2 = signal partially fails (only half the warriors join). Northern tribes subtract 1 from the roll (better drilled societies).

• Leader Down: If the war leader is killed, the band loses all remaining tokens for the turn and must use personal-example only – exactly the slide from "distributed leadership" into "every man for himself" you mentioned.

• Red Lance Moment Example: Red Lance spots the bolting Texan. Player spends 1 whistle token → entire dozen warriors peel off and charge as a pack (no one left behind). No token? Red Lance charges solo; others roll cohesion to join on their next activation. That five-second gap is real – and deadly fun on the table.

• Rally Mechanic: Any signal can double as a rally. Scattered warriors within range snap back to the signaler and regain 1 cohesion step automatically (faster than Rangers).

Print this as a single landscape or portrait page with the table centered, maybe add a quick sketch of a mirror flash or eagle-bone whistle if your layout program allows. It gives the Indian player that fluid, opportunistic feel while the cavalry player is stuck with one crisp bugle call per troop. The contrast keeps the player tension you built into the original Cynthia Ann's War rules: coordination is still the game, but the Plains warrior side gets more heroic "I see an opening – let's take it" moments.

If you want a ready-to-print PDF version, a version with little icons for each signal, or tweaks so it meshes even tighter with your exact activation dice pool, just tell me the details and I'll refine it. We can also add a matching "Cavalry Bugle Calls" sheet on the opposite page for side-by-side balance. This is going to make your northern-plains fights pop!

As usual, I will take some suggestions, reject others, and modify as necessary. And now I need to know more about Sioux banners at LBH.
