ⓘ Analysis Parameter: Raw combat force projection only. Does not reflect the mathematical average of operational quality scores.
Decisive Force Multiplier: The Armagnac party sustained its claim to legitimacy through proximity to the French royal family, but suffered from leadership instability and lacked strategic flexibility in the face of English invasion.
Burgundian Party
Commander: John the Fearless, Duke of Burgundy
Initial Combat Strength
%56
ⓘ Analysis Parameter: Raw combat force projection only. Does not reflect the mathematical average of operational quality scores.
Decisive Force Multiplier: The Burgundian party possessed superior supply capabilities through the economic power of Flanders and urban support; John the Fearless's demagogic skill and the English alliance provided a force multiplier.

Operational Capacity Matrix
5 Military Metrics — Staff Scoring System
The Burgundian party enjoyed a stable flow of supplies thanks to Flanders' wealthy trade networks and advanced urban economy, whereas the Armagnacs, largely dependent on the royal treasury, experienced financial bottlenecks until the advent of Joan of Arc.
John the Fearless, through strong personal leadership and populist promises, effectively mobilized the Burgundian party, while the Armagnac party, due to its coalition structure, struggled to achieve unity of command and frequently fractured among squabbling nobles.
The Burgundians demonstrated superior timing in capturing and holding strategic centers like Paris, exploiting the void after Agincourt to occupy the capital, whereas the Armagnacs were slow to reinforce defensive positions and failed to utilize interior lines.
Both sides waged a cautious intelligence war; the Burgundian propaganda machine effectively vilified the Duke of Orléans, while the Armagnacs failed to monitor secret negotiations with the English, leading to strategic surprises.
The Burgundians leveraged English longbowmen as mercenaries and tactical superiority against undisciplined troops like the Écorcheurs, while the Armagnacs, despite the mystical morale boost from Joan of Arc, remained technologically inferior.

Asian Art of War
Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
The Burgundian party succeeded in depriving the Armagnacs of popular support through effective propaganda among the University of Paris and urban population. John the Fearless gained psychological advantage by legitimizing the assassination of Louis d'Orléans as tyrannicide, but in the long term this strategy tarnished the party's reputation and led to diplomatic isolation.
Intelligence Asymmetry
Throughout the civil war, Burgundian agents infiltrated the royal council in Paris, gathering valuable intelligence on Armagnac plans. In contrast, the Armagnacs failed to anticipate developments at the Burgundian court and could not timely exploit the power vacuum following the assassination of John the Fearless.
Heaven and Earth
The harshness of winter slowed military operations in the late 1410s, providing a respite favorable to the Burgundians. The walls of Paris and the marshy terrain of the Loire Valley hindered Armagnac attacks, and the Burgundians combined these natural obstacles with defensive lines to hold the capital for extended periods.
Western War Doctrines
War of Attrition
Maneuver & Interior Lines
Burgundian forces, using interior lines, could rapidly shift between Paris and Flanders. The Armagnacs, hampered by heavy cavalry and a broad coalition structure, lost maneuverability, enabling John the Fearless to crush the Écorcheurs with a swift raid at Saint-Cloud in 1411.
Psychological Warfare & Morale
John the Fearless's charismatic leadership and 'friend of the people' image provided high morale to Burgundian troops. In the Armagnac ranks, the assassination of Louis d'Orléans created deep trauma, but the emergence of Joan of Arc temporarily reversed the psychological balance, reducing Clausewitzian 'friction'.
Firepower & Shock Effect
The Burgundians established firepower superiority by combining English longbows with disciplined foot soldiers. Repeated disordered charges by Armagnac knights were broken by this shock effect, particularly at the Battle of Othée, where timely deployment of Burgundian artillery proved decisive.

Center of Gravity · Intelligence · Dynamism
Center of Gravity
The Burgundian High Command correctly identified Paris as the center of gravity and focused all efforts on controlling the capital. The Armagnacs dissipated their Schwerpunkt by dividing forces between defending southern territories and retaking Paris, facilitating the Burgundian capture of the city in 1418.
Deception & Intelligence
John the Fearless delivered a pre-battle strategic blow by masterfully planning and executing the assassination of Louis d'Orléans; he also feigned negotiations with the English to divert Armagnac attention. The Armagnac side suffered an intelligence failure when Burgundian spies uncovered Bernard VII's plot to instigate a popular uprising during the failed siege of Paris in 1413.
Asymmetric Flexibility
The Burgundians demonstrated strategic flexibility by abandoning the English alliance and switching sides through the Treaty of Arras. The Armagnacs, due to their feudal structure, remained locked in a static defensive doctrine for a long time, achieving temporary adaptation only through the dynamism brought by Joan of Arc.
Section I
Staff Analysis
At the onset of the Armagnac-Burgundian Civil War, the balance of forces between the combatants was asymmetric. The Burgundian party enjoyed logistical superiority through the economic resources and trade networks of Flanders, which proved decisive in maintaining a standing army and hiring mercenaries. Under the charismatic leadership of John the Fearless, Burgundian forces quickly captured strategic centers like Paris, seizing the political initiative. In contrast, despite the advantage of royal legitimacy and broad feudal alliances, the Armagnac party remained on the defensive for an extended period due to weak unity of command and financial fragility. The external intervention of the English disrupted the strategic calculations of both sides, transforming the conflict into an extension of the Hundred Years' War and clouding the outcome.
Section II
Strategic Critique
The Burgundian High Command, after the assassination of John the Fearless, committed the error of excessive dependence on the English alliance, which eroded the party's national legitimacy and ultimately led to isolation within France. The Armagnac party, despite a post-Agincourt collapse in military morale, managed to employ Joan of Arc as a strategic force multiplier and rebuild royal authority. Both sides squandered national energy by perpetuating internal division in the face of the primary enemy, England—a striking example of Clausewitz's principle that 'war is the continuation of politics by other means.'
