Document 4: Crimean War: In the north Eristov pushed southwest, fought two battles, forced the Turks back to Batum, retired behind the Cholok River and suspended action for the rest of the year (June). In the far south Wrangel pushed west, fought a battle and occupied Bayazit. In the center the main forces stood at Kars and Gyumri. Both slowly approached along the Kars-Gyumri road and faced each other, neither side choosing to fight (June–July). On 4 August Russian scouts saw a movement which they thought was the start of a withdrawal, the Russians advanced and the Turks attacked first. They were defeated, losing 8000 men to the Russian 3000. 10000 irregulars deserted to their villages. Both sides withdrew to their former positions. About this time the Persians made a semi-secret agreement to remain neutral in exchange for the cancellation of the indemnity from the previous war.

In September 1854, an Allied landing force was beaten back with heavy casualties, and the Allies withdrew. The Russians escaped under the cover of snow in early 1855 after Allied reinforcements arrived in the region.
Document 7: Armenia: Due to the lack of success lately on the international level, in recent years, Armenia has rebuilt 16 Soviet-era sports schools and furnished them with new equipment for a total cost of $1.9 million. The rebuilding of the regional schools was financed by the Armenian government. $9.3 million has been invested in the resort town of Tsaghkadzor to improve the winter sports infrastructure because of dismal performances at recent winter sports events. In 2005, a cycling center was opened in Yerevan with the aim of helping produce world class Armenian cyclists.

Document 8: Crimean War: In June 1854, the Allied expeditionary force landed at Varna, a city on the Black Sea's western coast (now in Bulgaria). They made little advance from their base there.:175–176 In July 1854, the Turks under Omar Pasha crossed the Danube into Wallachia and on 7 July 1854, engaged the Russians in the city of Giurgiu and conquered it. The capture of Giurgiu by the Turks immediately threatened Bucharest in Wallachia with capture by the same Turk army. On 26 July 1854, Tsar Nicholas I ordered the withdrawal of Russian troops from the Principalities. Also, in late July 1854, following up on the Russian retreat, the French staged an expedition against the Russian forces still in Dobruja, but this was a failure.:188–190
Document 9: Crimean War: 1853: There were four main events. 1. In the north the Turks captured the border fort of Saint Nicholas in a surprise night attack (27/28 October). They then pushed about 20000 troops across the Cholok River border. Being outnumbered the Russians abandoned Poti and Redut Kale and drew back to Marani. Both sides remained immobile for the next seven months. 2. In the center the Turks moved north from Ardahan to within cannon-shot of Akhaltsike and awaited reinforcements (13 November). The Russians routed them. The claimed losses were 4000 Turks and 400 Russians. 3. In the south about 30000 Turks slowly moved east to the main Russian concentration at Gyumri or Alexandropol (November). They crossed the border and set up artillery south of town. Prince Orbeliani tried to drive them off and found himself trapped. The Turks failed to press their advantage, the remaining Russians rescued Orbeliani and the Turks retired west. Orbeliani lost about 1000 men out of 5000. The Russians now decided to advance, the Turks took up a strong position on the Kars road and attacked. They were defeated in the battle of Başgedikler, losing 6000 men, half their artillery and all their supply train. The Russians lost 1300, including Prince Orbeliani. This was Prince Ellico Orbeliani whose wife was later kidnaped by Shamyl at Tsinandali. 4. At sea the Turks sent a fleet east which was destroyed by Admiral Nakhimov at Sinope.
Document 10: Battle of Sinop: On 30 November the Russian squadron entered the harbor from the northwest in a triangular formation. Nakhimov maneuvered his fleet so that the Ottoman vessels were between the Russian ships and Sinop’s harbor defenses, shielding his own force and exposing the Ottomans to potential friendly fire. Nakhimov spaced his battleships evenly in two lines, covering the entire harbor with interlocking fields of fire. Russian gunners began to score hits on all the Ottoman targets. The shells fired by Russian guns immediately set Ottoman ships on fire. Panic-stricken sailors found firefighting efforts difficult amidst continued fire and almost constant shrapnel. After about 30 minutes of  combat the Ottoman frigate was shot full of holes and ran aground when her cable was cut. Imperatritsa Maria then attacked the 44-gun frigate Fazli Allah, which caught fire and grounded. Meanwhile, the other Russian ships engaged the Nizamie and Damiad, which were grounded. The Ottoman frigate Navek Bakhri exploded and sank along with the corvette Guli Sephid.Only one Ottoman vessel, the 12-gun paddle frigate Taif, managed to escape the battle while all the others were either sunk or purposely run ashore to prevent sinking. She fled to Constantinople and arrived on 2 December, informing the Ottoman government of the defeat at Sinop. Once the enemy fleet was destroyed the Russians engaged Ottoman shore batteries and destroyed them. During the fighting 37 Russians were killed and 229 were wounded, at least three of the ships of the line were damaged. Ottoman forces lost about 3,000 men killed, 150 were taken prisoner and their leader Osman Pasha was captured.
Document 11: Armenians: During Soviet rule, Armenian athletes rose to prominence winning plenty of medals and helping the USSR win the medal standings at the Olympics on numerous occasions. The first medal won by an Armenian in modern Olympic history was by Hrant Shahinyan, who won two golds and two silvers in gymnastics at the 1952 Summer Olympics in Helsinki. In football, their most successful team was Yerevan's FC Ararat, which had claimed most of the Soviet championships in the 70s and had also gone to post victories against professional clubs like FC Bayern Munich in the Euro cup.
Document 12: Eastern Front (World War I): This offensive was unanticipated by the Turks, as it was in the middle of winter. The Turkish situation was exacerbated by the Third Army's commander Kamil Pasha and Chief of Staff Major Guse absence. Coupled with an imbalance of forces -- the Russians had 325 000 troops, while the Turks only 78 000 -- the situation appeared grim for the Central Powers. After three months of fighting, the Russians captured the city of Trabzon on April 18, 1916.
Document 13: Crimean War: The landing was north of Sevastopol, so the Russians had arrayed their army in expectation of a direct attack. The allies advanced and on the morning of 20 September came up to the Alma river and the whole Russian army. The position was strong, but after three hours,:424 the frontal attack had driven the Russians out of their dug in positions with losses of 6000 men. The Battle of the Alma had 3,300 Allied losses. Failing to pursue the retreating forces was one of many strategic errors made during the war, and the Russians themselves noted that had they pressed south that day they would have easily captured Sevastopol.
Document 14: Levon Ambartsumian: Levon Ambartsumian (; ; born 1955) is an Armenian classical violinist and conductor. Levon Ambartsumian currently lives and works in Athens, Georgia, United States.
Document 15: Crimean War: Frustrated by the wasted effort, and with demands for action from their citizens, the allied force decided to attack the center of Russian strength in the Black Sea at Sevastopol on the Crimean peninsula. After extended preparations, the forces landed on the peninsula in September 1854 and fought their way to a point south of Sevastopol after a series of successful battles. The Russians counterattacked on 25 October in what became the Battle of Balaclava and were repulsed, but at the cost of seriously depleting the British Army forces. A second counterattack, ordered personally by Nicholas, was defeated by Omar Pasha. The front settled into a siege and led to horrible conditions for troops on both sides. Smaller actions were carried out in the Baltic, the Caucasus, the White Sea and in the North Pacific.
