Identity and development
The Peugeot / Oemichen Char 1918 was a French late-war prototype associated with Peugeot and the engineer Étienne Oehmichen. The protected project title uses Oemichen; Published accounts describe Oehmichen and Œhmichen as alternative spellings encountered in French sources. These name differences do not create different vehicles. Sources
The available evidence treats the final design as a compact, two-man, fixed-casemate fire-support vehicle. Its stronger secondary-source interpretation gives it a short 75 mm Blockhaus Schneider-type weapon, rather than the rotating machine-gun or 37 mm turret sometimes associated with the earlier light-tank concept. Sources
No production series or operational tank unit is established. The useful encyclopedia identity is therefore a prototype project with documented uncertainties, not a service family with a long variant tree. An archival grouping called Char d'assaut Oehmichen is evidence of a research trail, not a separate manufactured subtype. Sources
A different answer to the French light-tank problem
The project developed alongside the French search for more numerous and manageable armored vehicles. In the published framing, Peugeot offered both an industrial alternative to Renault and a different balance of firepower and protection. The final casemate configuration sacrificed the versatility of a rotating turret in favor of a heavier, short-barreled support weapon. Sources
Published accounts describe early work in 1917, while preserving disagreement over its precise starting point. Later descriptions concern trials in the autumn of 1918. A design may be technically interesting yet arrive too late to displace an established manufacturing and training system. The source does not establish a large canceled production order that can be counted as vehicles built. Sources
The comparison with the Renault FT is useful, but it is not a finding that one vehicle was superior in every technical respect. Accounts describe the Peugeot as potentially better protected and more powerful, while crediting the FT's turreted versatility and established production position. Those comparative judgments remain tied to their evidence and do not supply missing measurements of the Peugeot prototype. Sources
Casemate, armament, and protection
The final form is described as a tracked armored vehicle with a fixed forward fighting compartment. The driver sat beside the main weapon rather than beneath a rotating turret. The gunner's task was correspondingly dependent on the limited field of fire allowed by the casemate mounting and on the driver positioning the vehicle. Sources
The short 75 mm weapon is the best-supported final-prototype interpretation within the available accounts. A 37 mm weapon and machine-gun-only arrangements remain part of the earlier-concept or uncertain-configuration discussion. The source does not justify treating all these armaments as completed, interchangeable production variants. It also does not establish a full ammunition stowage plan, exact sight model, or reliably documented elevation and traverse limits. Sources
Armor is frequently summarized with a maximum figure of approximately forty millimeters, but the distribution by hull face is not securely established. The maximum does not establish a claim that every plate had that thickness. Similarly, descriptions of a secondary machine gun do not settle its exact model or mounting. Sources
Powertrain, mobility, and the two-man arrangement
The technical account places a Peugeot gasoline engine toward the front, with electrical power transmission associated with motors toward the rear. The reported output is about one hundred horsepower. This unusual arrangement is a reason to retain the project in the encyclopedia, but the available evidence does not provide a complete authenticated circuit, transmission specification, or reliability test series. Sources
Reported weight differs between approximately eight and nine tonnes. Published accounts give that disagreement rather than averaging it into a new figure. A reported speed of about 12.5 kilometers per hour likewise belongs to the sourced reconstruction and trial narrative, not to an independently checked performance certificate. Sources
Trench crossing appears as an important limitation of the final design. Its short running-gear arrangement and fixed fighting compartment made its tactical usefulness different from that of the FT. The two-man crew also concentrated driving, weapon handling, observation, and command tasks into a very small team. These are design implications discussed in the available evidence; a detailed crew-workload study is not available. Range, precise overall dimensions, ammunition capacity, and standard communications equipment remain unresolved and remain visibly so. Sources
Manufacture, evaluation, and absence of service
The source identifies one generally cited prototype, with Peugeot responsible for the industrial project. No confirmed series of production vehicles, export contract, licensed-manufacturing program, or operational issue is established. Sources
The operator history consists of French development and evaluation. The photographic records experimentation or demonstration, not combat. The account contains no demonstrated deployment to a fighting tank unit and no combat record from which to calculate battlefield effectiveness or losses. The vehicle's rejection or abandonment belongs to a procurement and evaluation story. Sources
The Armistice and the practical position of the FT limited the opportunity for further development. That explanation cannot be inflated into an assertion that the prototype passed all technical tests or would certainly have succeeded in a longer war. Published accounts give both promising features and shortcomings, particularly the narrow usefulness of the fixed heavy support weapon and the limitations in crossing trenches. Sources
Historical value and the remaining visual record
The Peugeot project illustrates a distinct alternative within late-war French tank development: additional protection and concentrated support firepower did not automatically produce a better general-purpose light tank. Its value lies in showing the choices available to designers and decision-makers, not in an invented record of military service. Sources
The available evidence does not establish a surviving vehicle or a direct line of subsequent operational descendants. Its strongest next steps are archival: original technical material, trial documentation, and better identification of the photographed configuration. These would clarify uncertain dimensions, armament, and internal layout. The unsettled design features are not firmly established by the available technical evidence. Sources
