Teacher: Now, understand the problem? Solve this instance: Question: How old was Arthur Wellesley, Marquess of Wellington when Kempt joined his army in Spain? Passage 1:On 4 November 1877 the Russian army achieved a victory at Uzunahmet, having inflicted heavy casualties on the Turks, which included 3,000 killed and wounded, 1,000 prisoners and 42 artillery pieces left by the panicked gunners, with a loss of only 1,200 men. Although the Turkish troops ceased resistance and were fleeing in disarray, with 4,000 of them deserting the army, a part of their infantry maintained order and retreated to the well-fortified position in Erzurum with 14 guns. The Russians, being miles away and exhausted by the battle, did not chase them and therefore missed a chance to capture Erzurum on the heels of the fleeing enemy. Having developed a plan of assault on the stronghold, the Russian army advanced under the cover of night, but had difficulties of movement control in the dark. A part of their troops from the 153th Infantry Regiment mistook their direction and captured one of the redoubts, Azizieh, all by themselves, without help from the rest of the army, but had to leave it due to the lack of support. All the three Turkish battalions stationed in the Azizieh redoubt were routed, numbering 1,600, whereas the Russians lost 400 or 600 men in this battle. After the Russians left Azizieh, the Turks made an attempt to counterattack them, but were successfully driven back. As the works of Erzurum were too strong to be taken by assault, the siege park was needed at Kars and in the following days the weather set in with a snowstorm, the Russians decided to withdraw their army and instead attack Kars, which they succeeded in capturing. Ahmed Muhtar Pasha, the Ottoman commander during the siege, requested reinforcements from Istanbul and was receiving them all through November. After epidemics broke out, he withdrew his forces to Bayburt for the remainder of the war. Muhtar Pasha was awarded the title Ghazi for his role in the defence of Erzurum, Gedikler and Yahniler. The city of Erzurum would be captured by the Russians a few months later, on 8 February 1878.
 Passage 2:José Efraín Ríos Montt (; June 16, 1926 – April 1, 2018) was a Guatemalan general, politician, and war criminal who served as President of Guatemala. Born in Huehuetenango, he was a dictator who took power as a result of a coup d'état on March 23, 1982. He was overthrown by his defense minister, Óscar Humberto Mejía Victores, in another coup d'état on August 8, 1983. In the 2003 presidential elections, Ríos Montt unsuccessfully ran as the candidate of the Guatemalan Republican Front (FRG). In 2007 he returned to public office as a member of Congress, thereby gaining prosecutorial immunity. He was protected from a pair of long-running lawsuits alleging war crimes against him and a number of his former ministers and counselors during their term in the presidential palace in 1982–83. His immunity ended on January 14, 2012, with the end of his term in legislative office. On January 26, 2012, he appeared in court in Guatemala and was formally indicted for genocide and crimes against humanity.
 Passage 3:Employed from 1807 to 1811 on the staff in North America, Brevet-Colonel Kempt at the end of 1811 joined Arthur Wellesley, Marquess of Wellington's army in Spain with the local rank of major general, which was, on 1 January 1812, made substantive. As one of Thomas Picton's brigadiers, Kempt took part in the great assault on Badajoz and was severely wounded. On rejoining for duty, he was posted to the command of a brigade of the Light Division (43rd Regiment of Foot, 95th Rifles, and 3rd Portuguese Light Infantry) in time to fight at the Battle of Vitoria on 21 June 1813. He also led his brigade at the Battle of the Pyrenees at the end of July, and at the Battle of the Bidassoa, where his troops stormed French defenses near Mont La Rhune on 7 October. While still commanding his brigade at the Battle of Nivelle on 10 November, he was again wounded. In 1814, he led his brigade at the battles of Orthez and Toulouse.
