The Erzurum Offensive (Russian: Эрзурумское сражение Erzurumskoe srazhenie ;Turkish: Erzurum Taarruzu) or Battle of Erzurum (Turkish: Erzurum Muharebesi) was a major winter offensive by the Imperial Russian Army on the Caucasus Campaign, during the First World War, that led to the capture of the strategic city of Erzurum. Ottoman forces, in winter quarters, suffered a series of unexpected reverses that led to a Russian victory.

After the defeat at the Battle of Sarikamish, the Ottomans tried to reorganize. The Armenian Genocide made supplying their forces a problem. Trade by Armenians, which had supplied the Ottoman Army, was disrupted. Dismissal of Armenian soldiers into labor battalions and their massacres further worsened the problem. However, throughout 1915, the northern sectors of this front remained quiet.
At the same time, the end of the Gallipoli Campaign would free up considerable Turkish soldiers. Nikolai Yudenich, commander of the Russian Caucasus Army, knew this and prepared to launch an offensive. He hoped to take the main fortress of Erzurum in the area followed by Trabzon. It was a difficult campaign as Erzurum was protected by a number of forts in the mountains.
Eight of these divisions were designated for the Caucasus Front. Yudenich believed he could launch an offensive before these divisions could be ready for battle.
The Russians had 130,000 infantry and 35,000 cavalry. Further, they had 160,000 troops in reserve, 150 supply trucks, and 20 planes of the Siberian Air Squadron.
The Ottoman High Command failed to make up the losses of 1915. The war in Gallipoli was using all the resources and manpower. The IX, X and XI Corps could not be reinforced and in addition to that the 1st and 5th Expeditionary Forces were deployed to Mesopotamia Campaign which did not show signs of ending soon. Ottoman High Command recognizing the dire situation on other fronts, decided that this region was of secondary importance. As of January 1916, Ottoman forces were 126,000 men, only 50,539 being combat soldiers. There were 74,057 rifles, 77 machine guns and 180 pieces of artillery. Many of the guns which were supposed to defend the city had been moved to Gallipoli to counter the British forces. The guns that were left in the region were older weapons and not in very good condition. The soldiers were not in good condition. They suffered from inadequate food as was typical of many Turkish soldiers at that time. Ottoman forces in the Caucasus Campaign were big on paper, but not on the ground. Another source claim that 78,000 troops were in this region, perhaps associating the number of rifles to actual soldiers.
Ottoman High Command did not expect any Russian operations during winter. Mahmut Kamil was in Istanbul, and his chief of staff, Colonel Felix Guse, was in Germany. General Yudenich launched a major winter offensive. In the middle of January, there was heavy snow, which often came up to 4 feet.
The Russians while having a slight edge in numbers, could not rely on numbers alone. For that reason, the Russian plan was to break through a weak part of the line.
On January 10, the initial offensive was directed at the XI Corps. The first engagement was at the Azkani village and its mountain crest of Kara Urgan. In four days the Russians managed to break through the XI Corps. XI Corps losses were high.
On January 17, at Battle of Koprukoy The forces at Köprüköy (the main town on the road to Erzurum) were forced to leave. By 18 January, the Russian forces approached Hasankale, a town on the road to Erzurum and the new location of the Third Army headquarters. on January 23 Kargabazar Dag Hinis. Within just one week, the defensive formation was dissolved.
On January 29, Mahmut Kamil Paşa returned from Istanbul. He could feel that the Russians would not only attack to Erzurum but also renew the offensive southern flank around Lake Van. Hınıs, located further south, was taken on February 7 to prevent reinforcements from Muş from coming in. Mahmut Kamil tried to strengthen the defensive lines. That drew most of the Turkish reserves and diverted Turkish attention away from the decisive attack farther north. On the same day, Russian forces captured Muş after the Battle of Mush. Muş was seventy miles from Erzurum.
On February 11 and 12th, the Deve-Boyun Ridge, an important artillery platform, was the scene of heavy fighting. To the north of the Deve Boyun ridge the Russian columns approached over the Kargapazar ridge, which the Turks considered impassable. The X Turkish Corps guarded that sector of the line, and its commander had positioned his divisions so that they were not mutually supporting. Mahmut Kamil had five divisions in the Deve-Boyun ridge area, but was slow to react to what was going on north of that position.
City of Erzurum
The Fortress was under Russian threat, both from north and east. With the victories, the Russian Army had cleared the approaches to Erzurum. The Russians were now planning to take Erzurum, a heavily fortified stronghold. Erzurum was considered as the second best defended town in the Ottoman Empire. The Fortress was defended by 235 pieces of artillery. The fortifications covered the city on a 180 degree arc in two rings. There were eleven forts and batteries covering the central area. The flanks were guarded by a group of two forts on each flank. The Ottoman 3rd Army lacked the soldiers to adequately man the perimeter. Also, casualties totaled 10,000 and an additional 5,000 had been taken prisoner, 16 pieces of artillery had been lost and 40,000 men had found refuge in Erzurum Fortress.
On February 11, Russians began to shell the fortified formations around Erzurum. Fierce fighting erupted. Turkish battalions of 350 men had to defend against Russian battalions of 1,000 men. There were few reinforcements for the beleaguered Turks. In three days Russians managed to reach the heights overlooking the Erzurum plain. It was now obvious for the command of the Turkish Third Army that the town was lost. Turkish units began to retreat from the fortified zones at the front and also evacuate the town of Erzurum.
On February 12, Fort Kara-gobek was taken. On the 13th, the Russians continued their attacks.
On February 14, Fort Tafet was taken, and with that the Russians had penetrated through both rings of the cities's defenses.
By February 15, the remaining forts surrounding Erzurum were evacuated.
Early in the morning of February 16, Russian cossacks were among the first to enter the city. Turkish units had successfully withdrawn and avoided encirclement, however casualties were already high. 327 pieces of artillery were lost to the Russians. Support units of the Third Army and around 250 wounded at the hospital of Erzurum were taken prisoner.
While aerial reconnaissance revealed that the Turks were retreating, the Russian pursuit was not effective as it could have been. Meanwhile, remnants of the X and XI Corps established another defensive line, 8 kilometers east of Erzurum.
The initial phase of the offensive, known as the Battle of Koprukoy, resulted in 20,000 casualties for the Ottomans and 12,000 for the Russians. At the end of the offensive in the storming of the city of Erzurum itself, the Russians captured some 9 standards, 5,000 prisoners and 327 guns. The Ottomans lost about 10,000 men killed and wounded, as well as 5,000 prisoners. The Russians lost 1,000 killed, 4,000 wounded and 4,000 became affected with frostbite.
The Ottoman Empire did not have a chance to enjoy the victory at the Battle of Gallipoli. The loss of Erzurum changed the atmosphere in an instant. V Corps (consisting of 10th and 13th Divisions) deployed from Gallipoli. On 27 February, Mahmut Kamil was replaced with Vehip Paşa. The new location of the headquarters became Erzincan. At that time 3rd Army had only 25,500 men, 76 machine guns and 86 pieces of artillery battle ready. As a further result of the Erzurum Campaign, Trabzon fell in April.
The Battle of Erzurum forms the climax of John Buchan's novel Greenmantle.
