, 1877, painting by
Aleksey Kivshenko Balkan theatre/Romanian War of Independence On 12 April 1877, Romania gave permission to the Russian troops to pass through its territory to attack the Turks. On 24 April 1877 Russia declared war on the Ottomans, and its troops entered Romania through the newly built
Eiffel Bridge near Ungheni, on the
Prut river, resulting in Turkish bombardments of Romanian towns on the Danube. On 10 May 1877, the
Principality of Romania, which was under nominal Turkish
suzerainty, declared its independence. , 1883 At the beginning of the war, the outcome was far from obvious. The Russians could send a larger army into the Balkans: about 300,000 troops were within reach. The Ottomans had about 200,000 troops on the Balkan peninsula, of which about 100,000 were assigned to fortified garrisons, leaving about 100,000 for the army of operation. The Ottomans had the advantage of being fortified, complete command of the Black Sea, and patrol boats along the
Danube river. They also possessed superior arms, including new British and American-made rifles and German-made artillery. In the event, however, the Ottomans usually resorted to passive defense, leaving the strategic initiative to the Russians, who, after making some mistakes, found a winning strategy for the war. The Ottoman military command in Constantinople made poor assumptions about Russian intentions. They decided that Russians would be too lazy to march along the Danube and cross it away from the delta, and would prefer the short way along the Black Sea coast. This would be ignoring the fact that the coast had the strongest, best supplied and garrisoned Turkish fortresses. There was only one well manned fortress along the inner part of the River Danube,
Vidin. It was garrisoned only because the troops, led by
Osman Nuri Pasha, had just taken part in defeating the Serbs in their recent war against the Ottoman Empire. The Russian campaign was better planned, but it relied heavily on Turkish passivity. A crucial Russian mistake was sending too few troops initially; an expeditionary force of about 185,000 crossed the Danube in June, slightly fewer than the combined Turkish forces in the Balkans (about 200,000). After setbacks in July (at
Pleven and
Stara Zagora), the Russian military command realized it did not have the reserves to keep the offensive going and switched to a defensive posture. The Russians did not even have enough forces to blockade Pleven properly until late August, which effectively delayed the whole campaign for about two months. At the start of the war, Russia and Romania destroyed all vessels along the Danube and
mined the river, thus ensuring that Russian forces could cross the Danube at any point without resistance from the
Ottoman Navy. The Ottoman command did not appreciate the significance of the Russians' actions. In June, a small Russian unit crossed the Danube close to the delta, at
Galați, and marched towards Ruschuk (today
Ruse). This made the Ottomans even more confident that the big Russian force would come right through the middle of the Ottoman stronghold. during Battle of Gorni Dubnik In the first month of the war, the Ottomans suffered a pair of significant naval losses on the Danube. The
turret ship was destroyed by a Russian artillery battery on 11 May. And on the night of 25–26 May, a Romanian torpedo boat with a mixed Romanian-Russian crew
attacked and sank the Ottoman monitor on the Danube. Under the direct command of Major-General
Mikhail Ivanovich Dragomirov, on the night of 27/28 June 1877 (
NS) the Russians constructed a pontoon bridge across the Danube at Svishtov. After a short battle in which the Russians suffered 812 killed and wounded, the Russians secured the opposing bank and drove off the Ottoman infantry brigade defending Svishtov. At this point the Russian force was divided into three parts: the Eastern Detachment under the command of
Tsarevich Alexander Alexandrovich, the future Tsar
Alexander III of Russia, assigned to capture the fortress of Ruschuk and cover the army's eastern flank; the Western Detachment, to capture the fortress of
Nikopol, Bulgaria and cover the army's western flank; and the Advance Detachment under Count
Joseph Vladimirovich Gourko, which was assigned to quickly move via
Veliko Tarnovo and penetrate the
Balkan Mountains, the most significant barrier between the Danube and Constantinople. Responding to the Russian crossing of the Danube, the Ottoman high command in Constantinople ordered Osman Nuri Pasha to advance east from Vidin and occupy the fortress of Nikopol, just west of the Russian crossing. On his way to Nikopol, Osman Pasha learned that the Russians had already captured the fortress and so moved to the crossroads town of Plevna (now known as
Pleven), which he occupied with a force of approximately 15,000 on 19 July (NS). The Russians, approximately 9,000 under the command of General Schilder-Schuldner, reached Plevna early in the morning. Thus began the Siege of Plevna, lasting for 145 days until 10 December. Osman Pasha organized a defense and repelled two Russian attacks with colossal casualties on the Russian side. At that point, the sides were almost equal in numbers and the Russian army was very discouraged. A counter-attack might have allowed the Ottomans to control and destroy the Russians' bridge, but Osman Pasha did not leave the fortress because he had orders to stay fortified in Plevna. in August 1877 Russia had no more troops to throw against Plevna, so the Russians besieged it, and subsequently asked the Romanians to cross the Danube and help them. On 9 August, Suleiman Pasha made an attempt to help Osman Pasha with 30,000 troops, but he was stopped by Bulgarians at the
Battle of Shipka Pass. After three days of fighting, the volunteers were relieved by a Russian force led by General
Fyodor Radetsky, and the Turkish forces withdrew. Soon afterwards, Romanian forces crossed the Danube and joined the siege. On 16 August, at
Gorni-Studen, the armies around Plevna were placed under the command of the Romanian Prince
Carol I, aided by the Russian general Pavel Dmitrievich Zotov and the Romanian general
Alexandru Cernat. in 1877 was significant, as it was the site of an
important Ottoman victory in 1396 which marked the
expansion of the Ottoman Empire into the Balkans. The Turks maintained several fortresses around Pleven which the Russian and Romanian forces gradually reduced. The Romanian 4th Division led by General
Gheorghe Manu took the
Grivitsa redoubt after four bloody assaults and managed to keep it until the very end of the siege. The Siege of Plevna (July–December 1877) turned to victory only after Russian and Romanian forces cut off all supply routes to the fortified Ottomans. With supplies running low, Osman Pasha made an attempt to break the Russian siege in the direction of
Opanets. On 9 December, in the middle of the night the Ottomans threw bridges over the
Vit river and crossed it, attacked on a front and broke through the first line of Russian trenches. Here they fought hand to hand and bayonet to bayonet, with little advantage to either side. Outnumbering the Ottomans almost 5 to 1, the Russians drove the Ottomans back across the Vit. Osman Pasha was wounded in the leg by a stray bullet, which killed his horse beneath him. Making a brief stand, the Ottomans eventually found themselves driven back into the city, losing 5,000 men to the Russians' 2,000. The next day, Osman surrendered the city, the garrison, and his sword to the Romanian colonel,
Mihail Cerchez. He was treated honorably, but his troops perished in the snow by the thousands as they straggled off into captivity. At this point, Serbia, having finally secured monetary aid from Russia, declared war on the Ottoman Empire again. This time there were far fewer Russian officers in the Serbian army but this was more than offset by the experience gained from the 1876–77 war. Under nominal command of Prince
Milan Obrenović (effective command was in hands of general
Kosta Protić, the army chief of staff), the Serbian Army went on offensive in what is now eastern south Serbia. A planned offensive into the Ottoman
Sanjak of Novi Pazar was called off due to strong diplomatic pressure from Austria-Hungary, which wanted to prevent Serbia and Montenegro from coming into contact, and which had designs to spread Austria-Hungary's influence through the area. The Ottomans, outnumbered unlike two years before, mostly confined themselves to passive defence of fortified positions. By the end of hostilities the Serbs had captured Ak-Palanka (today
Bela Palanka),
Pirot,
Niš and
Vranje. Russians under
Field Marshal Gourko succeeded in capturing the passes at the
Stara Planina mountain, which were crucial for maneuvering. Next, both sides fought a series of battles for
Shipka Pass. Gourko made several attacks on the Pass and eventually secured it. Ottoman troops spent much effort to recapture this important route, to use it to reinforce Osman Pasha in Pleven, but failed. Eventually Gourko led a final offensive that crushed the Ottomans around Shipka Pass. The Ottoman offensive against Shipka Pass is considered one of the major mistakes of the war, as other passes were virtually unguarded. At this time a huge number of Ottoman troops stayed fortified along the Black Sea coast and engaged in very few operations. A Russian army crossed the Stara Planina by a high snowy pass in winter, guided and helped by local Bulgarians, not expected by the Ottoman army, and defeated the Turks at the
Battle of Tashkessen and
took Sofia. The way was now open for a quick advance through
Plovdiv and
Adrianople to
Constantinople. Besides the
Romanian Army (which mobilized around 114,000 soldiers), more than 12,000 volunteer Bulgarian troops (
Opalchenie) from the local Bulgarian population as well as many
hajduk detachments fought in the war on the side of the Russians.
Caucasian theatre The Russian
1st Caucasus Army Corps was stationed in
Georgia and
Armenia, composed of approximately 50,000 men and 202 guns under the overall command of
Grand Duke Michael Nikolaevich,
Governor General of the Caucasus. The Russian force stood opposed by an Ottoman Army of 100,000 men led by General
Ahmed Muhtar Pasha. While the Russian army was better prepared for the fighting in the region, it lagged behind technologically in certain areas such as
heavy artillery and was outgunned, for example, by the superior long-range
Krupp artillery that Germany had supplied to the Ottomans. on June 8, 1877. A few days later, General
Arshak Ter-Gukasov relieved Russian defenses. The Caucasus Corps was led by a quartet of
Armenian commanders: Generals
Mikhail Loris-Melikov,
Arshak Ter-Gukasov (Ter-Ghukasov/Ter-Ghukasyan),
Ivan Lazarev and
Beybut Shelkovnikov. Forces under
Lieutenant-General Ter-Gukasov, stationed near
Yerevan, commenced the first assault into Ottoman territory by capturing the town of
Bayazid on 27 April 1877. Capitalizing on Ter-Gukasov's victory there, Russian forces advanced, taking the region of
Ardahan on 17 May; Russian units also besieged the city of
Kars in the final week of May, although Ottoman reinforcements lifted the siege and drove them back. Bolstered by reinforcements, in November 1877 General Lazarev launched a new attack on Kars, suppressing the southern forts leading to the city and capturing Kars itself on 18 November. On 19 February 1878, the strategic fortress town of
Erzurum was taken by the Russians after a lengthy siege. Although they relinquished control of Erzurum to the Ottomans at the end the war, the Russians acquired the regions of
Batum, Ardahan, Kars,
Olti, and
Sarikamish and reconstituted them into the
Kars Oblast.
Greek involvement During the course of the war, the majority of Greeks wanted to enter the war on Russia's side, however the Greek government decided reluctantly to not intervene, due to British neutrality. The British guaranteed that after the end of the war they would intervene themselves and assure equal rights for the Greek subjects of the Ottoman Empire, as long as Greece didn't join the war. Nevertheless, several Greek revolts broke out in
Crete,
Epirus,
Macedonia and
Thessaly demanding union with Greece. The
Greek Army invaded Thessaly in January 1878, but didn't officially declare war on the Ottomans; along with Greek irregular revolutionaries, the Greek Army won the
Battle of Mouzaki. However, the
Great Powers asked for Greece to recall its army, in return, they ensured that issues regarding the Greek communities would be raised in the post-war
Peace Conference. The Greek government accepted and, as a result, the rebellions were left unsupported and were crushed by the Ottomans. Three years later, with the
Convention of Constantinople, most of Thessaly (excluding
Elassona) as well as
Arta were ceded to Greece.
Kurdish uprising near the walls of
Kitay-gorod As the Russo-Turkish War came to a close, a Kurdish uprising broke out in the
Bohtan region, led by the brothers Osman Pasha Bedirkhan and Hüseyin Kenan Pasha. Taking advantage of Ottoman weakness, the rebels gained control over parts of the region for several months. After initial military efforts failed to fully suppress the revolt, the Ottoman authorities combined military pressure with negotiation, eventually securing the surrender of the leaders and ending the rebellion. In
Kars, Kurdish notables like
Abdürrezzak Bedir Khan and a son of
Sheikh Ubeydullah were supporters of the Russians.
Civilian government in Bulgaria during the war After Bulgarian territories were liberated by the Russian Army during the war, they were governed initially by a
provisional Russian administration, which was established in April 1877. The
Treaty of Berlin (1878) provided for the termination of this provisional Russian administration in May 1879, when the
Principality of Bulgaria and
Eastern Rumelia were established. The main objectives of the temporary Russian administration were to secure peace and order and to prepare for a revival of the Bulgarian state. ==Aftermath==
