Battle of Lule Burgas

Following the quick Bulgarian victory on the Petra – Seliolu – Geckenli line and the capture of Kirk Kilisse (Kırklareli), the Ottoman forces retreated in disorder to the east and south. The Bulgarian Second Army under the command of gen. Nikola Ivanov besieged Adrianople (Edirne) but the First and Third armies failed to chase the retreating Ottoman forces. Thus the Ottomans were allowed to re-group and took new defensive positions along the Lule Burgas – Bunar Hisar line. The Bulgarian Third Army under gen. Radko Dimitriev reached the Ottoman lines on 28 October. The attack began the same day by the army's three divisions – 5th Danubian Infantry Division (commander major-gen. Pavel Hristov) on the left flank, 4th Preslav Infantry Division (major-gen. Kliment Boyadzhiev) in the centre and 6th Bdin Infantry Division (major-gen. Pravoslav Tenev) on the right flank. By the end of the day the 6th Division captured the town of Lule Burgas. With the arrival of the First Army on the battlefield the following day, attacks continued along the entire front line but were met with fierce resistance and even limited counter-attacks by the Ottomans. Heavy and bloody battles occurred on the next two days and the casualties were high on both sides. At the cost of heavy losses, the Bulgarian Fourth and 5th Division managed to push the Ottomans back and gained 5 km of land in their respective sectors of the frontline on 30 October.

The Bulgarians continued to push the Ottomans on the entire front. The 6th division managed to breach the Ottoman lines on the right flank. After another two days of fierce combat, the Ottoman defence collapsed and on the night of 2 November the Ottoman forces began a full retreat along the entire frontline. The Bulgarians again didn't immediately follow the retreating Ottoman forces and lost contact with them, which allowed the Ottoman army to take up positions on the Çatalca defence line just 30 km west of Constantinople.

There were a large number of journalists who reported on the Battle of Lule Burgas, whose accounts provide rich details about this event.

Logistical Collapse and Ammunition Shortages

A decisive factor in the Ottoman defeat at the Battle of Lule Burgas was the near-total collapse of the logistical and supply systems. Throughout the engagement, the failure of the supply lines led to a critical lack of ammunition across all branches of the army. The Ottoman artillery was forced into silence as their stockpiles of shells were completely exhausted, leaving the infantry without fire support. Simultaneously, infantry units faced severe shortages of cartridges; although ammunition existed in rear depots, the breakdown in the railway and distribution networks prevented it from reaching the front lines.

Contemporary observers, most notably British war correspondent Ellis Ashmead-Bartlett, and modern military historians such as Edward J. Erickson, emphasize that the Ottoman defense disintegrated not necessarily due to Bulgarian tactical superiority, but because of this organizational failure. The inability to sustain fire, coupled with widespread hunger among the troops, rendered further resistance impossible and turned a strategic defense into a general retreat.^[8]
