5 Military Metrics — Staff Scoring System
Although regional alliances sustained supply lines, the burning of Condroz devastated agricultural yields, forcing both sides to accept French royal arbitration.
While the Liège coalition suffered tactical friction between church officials and city militias, the Namur command showed higher unity in backing the lord of Goesnes.
The Liégeois gained a spatial advantage by dismantling Goesnes, but the Namur-Luxembourg counter-attack at Jallet neutralized this superiority.
The Liégeois utilized local spies to identify Goesnes Castle's structural flaws, while the Namur command successfully hid the arrival timing of Luxembourg reinforcements.
Brabant's cavalry aid to Liège and Namur's alliance with Luxembourg acted as mutual multipliers, preventing either side from gaining a decisive victory.

Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
Both Liège and Namur blocked diplomatic channels by escalating a minor theft, making regional war inevitable and failing to resolve the dispute peacefully.
Intelligence Asymmetry
The Namur bailiff tracked down the thief at the Liège fair, but the Liégeois administration failed to predict the total retaliatory reflex of the Namur lords.
Heaven and Earth
The fragmented forest and rugged terrain of the Condroz restricted large troop maneuvers, turning the war into a low-intensity, destructive guerrilla attrition campaign.
Western War Doctrines
Feudal Attrition & Plunder
Maneuver & Interior Lines
Liège forces executed a rapid siege to destroy Goesnes Castle, but the Namur-Luxembourg allies gathered quickly to launch a counter-attack at Jallet.
Psychological Warfare & Morale
The destruction of over 60 villages in Condroz and civilian casualties caused fatigue and logistical exhaustion among the combatants of both factions.
Firepower & Shock Effect
The shock of heavy trebuchets used by Liégeois forces broke the Goesnes garrison, though this tactical momentum was later crushed by a cavalry charge at Jallet.
Adaptive Staff Rationalism
Center of Gravity · Intelligence · Dynamism
Center of Gravity
The Liège army focused its center of gravity on dismantling Goesnes Castle, while the Namur coalition positioned its weight along Ciney and Jallet counter-attack lines.
Deception & Intelligence
Namur knights infiltrated the Liégeois siege camp under the cover of night, setting supply tents on fire and forcing the besiegers to temporarily withdraw.
Asymmetric Flexibility
Both sides remained bound to classical feudal siege and raid doctrines, failing to demonstrate any radical flexibility in troop organization or tactics.
Section I
Staff Analysis
The 1272 War of the Cow is an extreme example of how feudal legal systems, personal honor disputes, and alliances can escalate a petty theft into a massive regional catastrophe. Militarily, the war was executed through typical medieval siege warfare and rural attrition raids. While the Liégeois achieved a tactical victory by dismantling Goesnes Castle with siege trebuchets, they failed to handle the open-field cavalry threat posed by Namur-Luxembourg forces. The exhaustion of logistics and total ruin of Condroz agriculture eventually forced a diplomatic settlement rather than an outright military victory.
Section II
Strategic Critique
The critical error of the Namur coalition was burning Ciney to satisfy Goesnes' desire for revenge, escalating the war beyond return and antagonizing Brabant. The primary Liège mistake was the bailiff's execution of the thief, which triggered the diplomatic crisis, and subsequently dividing their forces into scattered plunder groups after destroying Goesnes Castle, leaving them vulnerable to the counter-attack near Jallet.
