5 Military Metrics — Staff Scoring System
The Ottoman garrison held a strong defensive position behind the walls of Berat Castle and could remain linked to supply lines from Anatolia, whereas the League of Lezhë lacked the logistical depth for a prolonged siege; it depended on Neapolitan artillery for firepower, but sustaining these troops was limited. Skanderbeg's departure to Vlorë relaxed the siege, allowing the Ottomans to use interior supply lines to receive reinforcements.
The Ottoman relief force under Ishak Bey correctly identified the center of gravity and defeated the besiegers through surprise. In contrast, Skanderbeg's decision to delegate the siege to Karl Muzakë Thopia and divide his forces created a command weakness; Thopia fell for the Ottoman garrison commander's delaying tactic and loosened siege discipline, a disastrous C2 error.
Ottoman forces controlled the timing of the battle by attacking in mid-July when the siege was lax; Berat Castle's elevated and commanding terrain provided the defenders observation and counter-attack advantages during the assault. The League of Lezhë, on the other hand, made a positional error and was exposed to cavalry shock on open ground.
The Ottoman Empire likely leveraged unrest within the League of Lezhë and command fractures to dispatch Ishak Bey in time; additionally, the garrison commander's surrender negotiation ploy exposed the besiegers' intelligence gap. Conversely, the League remained unaware of the approaching Ottoman reinforcements, and Moisi Golemi's betrayal deepened the intelligence failure.
Both sides possessed distinct force multipliers: the League's Aragonese-Neapolitan artillery increased its siege capacity, while Skanderbeg's charisma kept morale high; however, the disciplined Ottoman cavalry's sudden shock assault and the garrison's wall advantage nullified the artillery superiority. Skanderbeg's absence from the field accelerated the morale collapse.

Asian Art of War
Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
The Ottoman garrison commander delayed the League of Lezhë by feigning surrender negotiations, winning time without fighting and allowing reinforcements to arrive. This passive resistance strategy aligns with Sun Tzu's principle of 'breaking the enemy's will.' Additionally, Moisi Golemi's defection weakened the League's political and military cohesion before the battle commenced.
Intelligence Asymmetry
The Ottoman command better analyzed the League of Lezhë's internal divisions and siege timetable, penetrating the besiegers' decision loop through the garrison commander's deception. The League, however, correctly assessed neither the enemy's military strength nor its own command weakness; reconnaissance was reduced to a minimum after Skanderbeg's departure.
Heaven and Earth
The July summer heat was debilitating for armored troops. Berat Castle, built on a high rocky outcrop overlooking the Osum River valley, offered natural defensive advantages. This terrain allowed the Ottoman garrison to conduct an effective defense with limited forces while complicating the besiegers' artillery deployment and assault maneuvers. The Ottoman relief cavalry fully exploited its maneuvering capability on the valley's open plains.
Western War Doctrines
Siege/Positional Challenge
Maneuver & Interior Lines
The Ottoman Empire used the advantage of interior lines to rapidly transfer Ishak Bey's cavalry to Berat, pinning the besiegers on exterior lines. The League of Lezhë's static siege arrangement proved helpless against the swift Ottoman cavalry maneuver. Skanderbeg's departure toward Vlorë prevented a unified response and made it impossible to establish any flexible defensive line.
Psychological Warfare & Morale
Skanderbeg's absence from the battlefield caused a moral collapse among Albanian troops, embodying Clausewitz's concept of 'friction.' Under Karl Thopia's leadership, the besiegers were routed upon the sudden appearance of Ottoman cavalry. In contrast, the Ottoman garrison and relief force displayed high morale driven by holy war motivation and the will to victory.
Firepower & Shock Effect
The Ottoman cavalry's surprise and concentrated attack on the siege lines rendered the League's artillery superiority useless and triggered an immediate psychological collapse. Unable to coordinate firepower with maneuver, the Albanian forces dissolved under the shock effect. The Aragonese-Neapolitan artillery became ineffective in the sudden close combat.
Adaptive Staff Rationalism
Center of Gravity · Intelligence · Dynamism
Center of Gravity
The Ottoman command correctly identified the center of gravity, focusing on preventing the fall of Berat Castle, and committed the entire force at the critical moment of the siege. The League of Lezhë, however, misjudged its center of gravity, dispersing energy with Skanderbeg's movement to Vlorë and failing to maintain pressure on the castle. The Ottoman resistance center was accurately targeted and crushed.
Deception & Intelligence
The Ottoman garrison commander's offer to surrender if no reinforcements arrived within a certain period was a classic deception operation, completely misleading the League's command council. This ruse slowed the enemy's operational tempo and bought critical time for reinforcements. Additionally, Moisi Golemi's betrayal can be considered a strategic intelligence success.
Asymmetric Flexibility
Ottoman forces demonstrated doctrinal superiority by flexibly transitioning from static defense to a rapid offensive concept. The League of Lezhë, after Skanderbeg's departure, remained locked in a rigid siege formation, unable to adapt to changing battle conditions (despite intelligence of approaching reinforcements) and collapsed without showing asymmetric flexibility.
Section I
Staff Analysis
Initially, the League of Lezhë had firepower and numerical superiority with its 14,000-strong army and Aragonese-Neapolitan artillery. The garrison's weak position suggested the castle could fall. However, Skanderbeg's decision to move toward Vlorë divided his forces, lifted the pressure on Berat, and left command in the hands of an inadequate leader, creating a C2 failure. The Ottoman side used its interior lines to swiftly dispatch a relief force, launching a surprise assault at the most critical moment of the siege and reversing the course of the battle.
Section II
Strategic Critique
Skanderbeg's greatest mistake was leaving the front with a significant portion of his troops before the siege was concluded, entrusting command to Karl Muzakë Thopia, a commander of limited tactical competence. This decision violated the principle of maintaining the center of gravity. In contrast, the Ottoman command executed an extremely rational operational art through the garrison commander's diplomatic delaying tactic and Ishak Bey's determined attack. The League's intelligence and reconnaissance failure, combined with Moisi Golemi's betrayal, made defeat inevitable.
