"Assort" and the Military's Secret Map of American Strikes
By Miriam Adler ·
Industrial workers were monitored by a clandestine military unit whose code for a looming strike remains a ghost in the archives, masking the identities of the informants who betrayed them.
A worker in a Wisconsin tool-and-die shop or a steel mill in Pennsylvania once walked into a trap laid by a man he had never met, based on 'advice' he never saw. That advice, transmitted in a coded flash to a military desk, likely cost that worker his livelihood, his freedom, or his standing in a union, all to ensure that the wheels of industry never stopped turning.
What survives of this operation is not the correspondence itself, but a catalogue of the secret language used to conduct it. This finding aid—the archival map of a vanished series—establishes the existence of a telephone directory and a lexicon of codes used by the Military Intelligence Division, Negative Branch, Plant Protection Section (the record). This was the counter-intelligence arm of the Army, tasked with preventing espionage and sabotage, but the lexicon reveals a focus that shifted from foreign spies to American laborers.
"According to advice strike will take place"
The most damning entry in the lexicon is the code "Assort", which the record defines as: "According to advice strike will take place." The use of the word "advice" is the pivot upon which the entire operation turns. In the language of intelligence, "advice" is not a suggestion; it is a report from a human source—an informant.
Because the actual cables and reports are not part of this specific list, the identities of these informants are missing. But the pattern suggests that the Negative Branch did not simply monitor public grievances; they planted eyes and ears inside the plants they were tasked to protect. The military was not waiting for a strike to be announced by a union leader; they were receiving a tip-off from a mole inside the shop floor.
This was not a passive observation post. The record lists the code "Atoned" to mean "Advise on what date," and "Deem" to mean "Do not accept." This is the vocabulary of a command-and-control center managing a domestic crisis in real-time. When the Army signaled "Turban", it meant "Things look good." The stakes were not national security in the sense of foreign borders, but the security of production quotas.
Akit and Amis
To move this information, the Negative Branch relied on a hierarchy of coded roles within the War Department, the ministry that oversaw the nation's military forces until 1947. The record shows that the Chief Signal Officer—the commanding officer of the Army Signal Corps who managed everything from cryptography to strategic communications—was identified as "Akit". The Ordnance Inspector, the officer responsible for the material and logistical support of the Army's weaponry, was "Amis".
The line here is clear: the intelligence gathered by the Plant Protection Section was piped directly to the men who controlled the communications and the hardware. If a strike was signaled as "Assort," the Chief Signal Officer and the Ordnance Inspector were the ones who ensured the military's response was coordinated and its logistics seamless. By coding these titles, the War Department ensured that even if a message were intercepted, the specific actors in the suppression effort remained anonymous.
This was a closed loop of power. The intelligence was gathered by the Negative Branch, filtered through a secret lexicon, and delivered to the top of the Signal and Ordnance hierarchies. The workers being watched were not just fighting their bosses; they were fighting a military apparatus that had systematized the betrayal of the shop floor.
Abduct, Ache, and Advent
The geography of this surveillance was not random. The Negative Branch utilized specific codes for industrial hubs. Atlanta, the capital of Georgia and a Beta+ global city, was "Abduct". Milwaukee, the most populous city in Wisconsin and a center of Lake Michigan manufacturing, was "Ache". Pittsburg, the steel heart of Pennsylvania, was "Advent".
The choice of these cities reveals the Negative Branch's true priority. These were not strategic military bases; they were the lungs of American industry. By assigning these cities codes, the military treated the American interior as a theater of operations. The irony is sharp: the "Plant Protection" offered by the Military Intelligence Division was not protection for the plants themselves, but protection for the output of those plants against the people who operated the machinery.
This operational footprint connects directly to a related series of "Unclassified Decimal Files," which the record notes contain reports on "domestic disturbances, especially labor disputes" and the "deployment of military police units." The codes "Abduct," "Ache," and "Advent" were the triggers. When a city was flagged with "Assort," the "Decimal Files" suggest the response was the arrival of military police.
The Ghost in the Negative Branch
The desk's reading is that the Negative Branch operated as a domestic political police force under the guise of counter-espionage. The nomenclature itself—"Negative Branch"—suggests a unit designed to neutralize threats, a void where the usual rules of domestic law were suspended in favor of military efficiency. If the shape of this file is what it appears to be, the 「Plant Protection Section」 was essentially a liaison office between corporate management and the War Department.
There is a missing layer of corporate collaboration here. The record establishes that the Negative Branch maintained telephone lists for "Plant Protection District offices." The pattern suggests these offices served as the intake valves for private factory security reports. The military did not have an agent in every tool-shop in Milwaukee; instead, the company security chiefs—men paid by the owners to break unions—fed their "advice" into the military's coded system. The Army provided the legitimacy and the muscle; the corporations provided the names.
The still-withheld pages of this operation, the actual traffic that used the codes "Assort" and "Abduct," would likely reveal a roster of American citizens who were paid to spy on their coworkers. Those pages are the ones the archive protects, because while a list of codes is a curiosity, a list of informants is a liability.
The Negative Branch's legacy is the blueprint for the modern security state's approach to civil unrest: the fusion of private corporate intelligence with federal military power. The workers in Pittsburg and Milwaukee paid for this system with their livelihoods, while the men who signaled "Turban" to indicate that things looked good did so from the safety of a coded line.
