5 Military Metrics — Staff Scoring System
The Bulgarians engaged in a short-term, deep raid, operating logistically close to their borders; in contrast, Byzantium, despite the civil war, demonstrated greater resilience through its established supply networks and fortified cities in Thrace.
The Bulgarian command structure was unified under the Tsar, while on the Byzantine side the conflict between Andronikos II and Andronikos III paralyzed the chain of command, making effective resistance initially impossible.
George Terter chose the peak of the Byzantine civil war for his offensive, perfect timing, and directed his main effort at the strategic city of Philippopolis and the forts en route to Adrianople, exploiting geographical advantages; Andronikos III's intervention blunted the Bulgarian momentum.
The Bulgarians had accurate intelligence on Byzantine political turmoil and defensive weaknesses; Byzantium received late warning of the Bulgarian campaign and its intelligence capability had collapsed due to internal strife.
Both sides were at similar technological levels; for the Bulgarians, morale and opportunism were key, while for the Byzantines, professional military tradition and the later commitment of resolute leadership were the main force multipliers.

Victor's Strategic Gains
- ›Bulgarian forces, exploiting the void from the Byzantine civil war, captured Philippopolis and its surroundings, briefly achieving regional superiority by advancing toward Adrianople.
- ›Bulgarian garrisons were installed in the captured territories, attempting partial integration of the region.
Defeated Party's Losses
- ›Emperor Andronikos III's counter-offensive repelled the Bulgarian forces, reclaiming the lost areas in the Adrianople direction and halting the Bulgarian advance.
- ›The sudden death of George Terter II eliminated the opportunity to consolidate gains, resulting in the campaign's strategic failure.

Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
Instead of forcing a major field battle, George Terter II exploited the political paralysis caused by the civil war to achieve rapid territorial gains with virtually no resistance, thus capturing strategic points almost without fighting.
Intelligence Asymmetry
Bulgarian intelligence accurately identified the divisions in the Byzantine court and military weakness, allowing precise timing and direction of the operation; Byzantium, due to factional enmity, remained unaware of Bulgarian preparations.
Heaven and Earth
The open terrain of the Thracian plain facilitated rapid maneuver and deep penetration for the Bulgarian raiders; however, the region's fortified cities and defensive positions in the Balkan foothills provided Byzantium with strongpoints. Favorable seasonal conditions also accelerated the Bulgarian advance.
Western War Doctrines
Delaying Action
Maneuver & Interior Lines
Using their interior lines advantage, the Bulgarian forces rapidly advanced toward Philippopolis and Adrianople; Byzantium lost valuable time trying to assemble its scattered forces due to the civil war, employing an external lines strategy only after Andronikos III's intervention.
Psychological Warfare & Morale
The will to victory and promise of booty gave the Bulgarian troops high morale, while on the Byzantine side, the despair of civil conflict and loyalty crisis caused initial collapse. However, the young Andronikos' arrival at the front reinvigorated Byzantine resistance.
Firepower & Shock Effect
The conflict centered on sieges and cavalry raids rather than major pitched battles; thus, psychological pressure and forcing surrenders were decisive rather than massed firepower or shock cavalry maneuvers. Andronikos III's counter-offensive created a limited shock effect, forcing Bulgarians to retreat.
Adaptive Staff Rationalism
Center of Gravity · Intelligence · Dynamism
Center of Gravity
George Terter designated the politically and economically vital city of Philippopolis as the center of gravity, concentrating his forces there. The Byzantine resistance center was initially scattered garrisons; when Andronikos III took command, the Adrianople line became the true center of gravity.
Deception & Intelligence
There is no record of a significant deception operation; the Bulgarians primarily benefited from the strategic surprise generated by the Byzantine civil war. The Byzantine recovery and counter-attack under Andronikos III itself created an operational surprise effect.
Asymmetric Flexibility
The Bulgarian doctrine exhibited a flexible structure based on rapid raiding and probing enemy resistance, opting to withdraw rather than accept battle when faced with stiff opposition. Byzantium showed flexibility by transitioning from passive defense to active defense and counter-offensive under Andronikos III.
Section I
Staff Analysis
The campaign conducted by George Terter II in 1322-1323 was an opportunistic operation based on the principles of speed and surprise, exploiting the strategic opportunity created by the devastating civil war between Andronikos II and Andronikos III. In the initial phase, the Bulgarian Command's intelligence superiority and precise timing enabled the capture of the major fortress city of Philippopolis with almost no organized resistance. The Byzantine defense collapsed due to the command paralysis and loyalty crisis caused by the dual-headed authority; local garrisons were left to their fate. However, the character of the campaign changed with Andronikos III's arrival in Thrace and the consolidation of his forces, which stopped and pushed back the Bulgarian advanced elements through attrition and counter-attacks. Ultimately, the sudden death of George Terter removed the momentum, preventing the Bulgarian side from transforming tactical gains into an operational or strategic victory. This is a classic case of a 'command crisis and opportunism' battle, illustrating how sudden leadership change can overturn strategic outcomes.
Section II
Strategic Critique
George Terter II succeeded in strategic planning but lacked operational depth. Although the fall of Philippopolis was a significant prestige and logistical gain, his advance was slow enough to allow Andronikos III to recover. The most critical mistake was overextending supply lines in the direction of Adrianople without seeking a decisive battle to destroy the Byzantine center of resistance. For Byzantium, the civil war was strategic suicide, completely neglecting border security. However, the young Andronikos' decision to take personal command was correct. For both sides, the battle highlights the strategic importance of command continuity: with George Terter's death, Bulgaria's gains evaporated.
