The Battle of Lumë (, ) was a series of clashes during the First Balkan War between Albanian local forces and the army of the Kingdom of Serbia. The conflict took place between 15 November and 5 December 1912 in the Lumë.

During the First Balkan War, Serbian forces took advantage of the power vacuum left by the crumbling Ottoman Empire to invade and conquer Luma region in late October and early November 1912. While Serbian and Montenegrin forces generally faced minimal resistance from local Albanian irregulars, the tribes of the Luma region proved to be a exception. Their ability to successfully counter the advancing units was largely attributed to the highly challenging and advantageous mountainous terrain they utilized for their defense. Though, the rebellion was soon suppressed and the Serbian army established firm military rule over the territory.

During the operations and the following occupation, the Serbian government conducted systematic massacres, rapes, destruction of villages, and other atrocities against the civilian population that devastated the region. The war crimes were part of a larger campaign to ethnically cleanse the region of Albanians. Atrocities in Luma were likened to colonial era genocidal campaigns.

Albanian uprising The initial Serbian march through this area toward the Adriatic Sea was carried out peacefully and in close cooperation with several local tribes, particularly the Mirditë. However, as soon as strong Serbian detachments reached the coast and engaged Ottoman forces, revolts broke out in their rear, prompting the Serbian Third Army to undertake the disarming of villages along the main routes. The entrance of Serbian forces into Luma was accompanied by clashes, property destruction, and the burning of houses, which prompted a localized rebellion. In early November 1912, four detachments of the Šumadija Division I were dispatched to the Prizren region with orders to disarm the local population, with explicit instructions to act "mercilessly" if resistance was encountered. Between 8 and 13 November, Serbian units secured various sectors including Opoja, Gora, and Has. As the Serbian Third Army brought in major reinforcements from Kosovo and Macedonia, self-organized Albanian fighters were initially forced to retreat toward the banks of the White Drin and Mount Koritnik. General Božidar Janković, commander of the Third Army, issued an ultimatum to the people of Luma, demanding that their leaders and clerics surrender for negotiations and that the population hand over their weapons. Furthermore, the army demanded that the locals disarm Albanian fighters who had arrived from other parts of Kosovo, or reveal the exact locations of rebel leaders such as Isa Boletini, Ramadan Zaskoci, Riza Bey, Islam Spahiu, and Bajram Daklani. The Serbian command also required Luma's leaders to guide their troops through the villages, inform on the resistance, and provide five hostages from each village to be sent to Prizren, threatening to bombard their properties and villages if these conditions were not met.

The local population rejected these terms and continued their resistance, heavily supported by reinforcements from neighboring areas such as Dibra, Opoja, and Gora, led by prominent local figures including Elez Isufi, Isuf Xhelili, Xhafer Doda, Ramadan Zaskoci, and Islam Spahiu. Notably, prominent fighters like Isa Boletini were already engaged in clashes against the Serbian army in Kolesjan during this period. On 9 November, the Luma Detachment—comprising the 3rd Battalion of the 10th Infantry Regiment and a machine-gun section—reached Lumë kulla. Sensing that the local population was preparing for combat, the commander requested reinforcements. On 13 November, the 4th Battalion and a platoon of mountain artillery arrived. Meanwhile, the 3rd Battalion moved through Luma, struggling to cross the swollen Šija river to reach the village of Bicaj. As Serbian patrols began disarming local villages, Ljusna, Kondas, and Ujëmisht refused to comply and prepared for defense. By 14 November, the 3rd Battalion held a position on the left bank of the Šija, though the front was overextended and tactically compromised; the right flank was exposed to fire from across the Black Drin, and the left was vulnerable to encirclement from the slopes of Mount Gjallica. Furthermore, the swollen Šija river trapped the battalion’s supply and medical stations behind them.

At first, an estimated 600 to 800 Albanians were engaged. However, this force grew, and approximately 2,000 Albanian fighters, supported by two slow-firing artillery pieces, deployed in a horseshoe formation, encircling the Serbian positions from the east and west. On 15 November, the conflict escalated into a full-scale battle, and the region entered a state of active warfare that lasted for three days. Between 15 November and early December, intense fighting continued in Luma as local irregular units mounted fierce resistance. The Serbian mountain artillery, having crossed the river late and lacking necessary sighting and range-finding equipment, proved ineffective. Despite fierce fighting and attempts by a rifle company to take the dominant heights of Mount Gjallica, the terrain—characterized by steep slopes and rugged rock—rendered the maneuver unsuccessful. On 16 November, under sustained pressure and sudden flanking fire from the direction of Bicaj and Kolesjan, Serbian lines began to collapse. Recognizing the numerical superiority of the rebels, the commander of the 10th Regiment ordered a retreat to the right bank of the Luma river. However, as the crossing was not pre-organized and the water levels were too high to wade, the detachment remained split and disordered overnight.

In the dawn of 17 November, the detachment retreated toward Podbreg and Lumë kulla under heavy fire. The Serbian forces, exhausted, starving, and demoralized, were eventually forced back to Vërmica, essentially retreating as far as Prizren. The Luma Detachment suffered heavy casualties in the process, with many soldiers and horses drowning in the river during the chaotic withdrawal. Official military records place Serbian losses at 176 to 198 dead and 31 to 88 wounded. Contemporary wartime communications from the period reflect highly inflated claims regarding casualties; a primary report forwarded by Aqif Pasha Elbasani to the Albanian government claimed that local forces had killed nearly six battalions of Serbian soldiers and forced the remainder out of Luma.

Following the clashes, the Serbian military utilized its overwhelming numerical and material superiority. According to the Zadar-based newspaper Narodni list (14 December 1912) and subsequent Serbian military documents, following bloody engagements at the Vizier's Bridge, Lumë kulla, the Luma plain, and the slopes of Mount Gjallica and Kolesjan down to the Black Drin, no village was left unlooted or unburned. The scale of the destruction and massacres was so extensive that contemporary reports stated "Luma no longer exists." Reports of these events reached British Foreign Secretary Edward Grey, who raised the issue with the Serbian representative in London; in response, Serbian Prime Minister Nikola Pašić instructed his diplomats to explicitly deny the reports.

The conflict in the region was further complicated by heightened diplomatic tensions known as the "Prochaska Affair." Serbian authorities explicitly blamed the Austro-Hungarian consul in Prizren, Oskar Prochaska, for clandestine activities aimed at instigating the local Albanian population to armed resistance by promising them Austro-Hungarian assistance. While this diplomatic scandal was shaking public opinion in Austria, the Serbian Third Army compiled a dossier on the case. Tensions had peaked earlier when Prochaska mail, sent on 23 October, was seized by Serbian forces at the post office in Ferizaj (Uroševac). In these letters, the consul labeled the Serbs and Montenegrins as "savages" and claimed that the Serbian army had bombarded, burned, and massacred the inhabitants of Pristina—a claim the Serbian command vehemently denied, asserting that peaceful inhabitants were protected. Furthermore, Prochaska reported the presence of 3,000 Albanians from Luma in Prizren. These intercepted letters were immediately handed over to the Supreme Command and Prince Alexander, fueling the Serbian conviction that the uprisings in their rear were being actively orchestrated by foreign powers.

Serbian counter-offensive

Realizing that the initial forces were insufficient to suppress the uprisings in Luma, Has, and Dukagjin, the commander of the Serbian Third Army sent reinforcements totaling four battalions and ordered a rapid intervention to pacify the rebelling areas. As the Supreme Command had not dispatched the requested reinforcements or a detachment from Debar, the Army commander deployed the 11th and 12th Infantry Regiments (two battalions each), along with the 2nd Battalion of the 10th Infantry Regiment attached to the 12th. Two smaller detachments were ordered to assist from the direction of Has, while an infantry detachment advanced from Opolje and Gora. The corresponding operational orders explicitly mandated harsh measures against the rebelling villages.

The Opolje Detachment, consisting of the 1st Battalion of the 19th Infantry Regiment, the 8th Mountain Battery, and 15 cavalrymen, was tasked with assisting the main column by securing the areas east of Mount Koritnik from Albanian insurgents. On 18 November, near the village of Plava, the detachment absorbed two companies previously deployed to Opolje and Gora that had been pushed back from Šištevac. Advancing with combat security, the detachment reached Vranište and camped there. The following day, on 19 November, they engaged enemy forces at the Borje–Globočica ridge. Following a five-hour battle where the 8th Mountain Battery was effectively utilized, the insurgents retreated in disorganized groups. By evening, the detachment had reached Šištevac and Novo Selo.

Finding itself significantly ahead of the main column on 20 November, the Opolje Detachment halted its advance and secured positions east of Kolovoz. Meanwhile, the main column (11th and 12th Infantry Regiments), under the command of the Šumadija Division I, had already reached the northwestern slopes of Koritnik, west of Morina. Albanian forces held defensive lines southwest of Barloci, anchored between Koritnik and the White Drin. Around noon on 20 November, the vanguard of the 12th Regiment initiated an attack. To establish a tactical link with the Opolje Detachment, two companies of the 11th Regiment were sent along the Koritnik ridge. Subjected to heavy artillery and rifle fire, the Albanian defenders abandoned their positions around 14:00, retreating to the southwestern slopes of Koritnik to mount a new defense. This attempt was thwarted by a swift assault from the first echelon of the 12th Regiment. The insurgents retreated in disarray towards Podbreg and the Vizier Bridge. The 12th Regiment pursued them to the Luma river, holding the right bank while setting outposts on the left, whereas the 11th Regiment halted at Gjeđeni. Albanian historians note that from mid-November, as massive reinforcements from the Serbian Third Army poured into Luma, the self-organized Albanian forces were compelled to retreat towards the banks of the White Drin and Mount Koritnik. Acknowledging the clear military superiority of the advancing Serbian troops, local resistance ultimately collapsed after bloody engagements around the Vizier Bridge and Lumë kulla. Concurrently, two smaller detachments dispatched from Gjakova advanced through the Has region without encountering resistance, effectively securing the route to Lumë kulla and the Vizier Bridge.
