Example Input: Question: Which of the battles La Hire fought with Dunois was the deadliest? Passage:La Hire joined Charles VII in 1418, when the English army invaded France. Although not a noble, La Hire was regarded a very capable military leader as well as an accomplished rider. Three years later, in 1421 he fought at the Battle of Baugé. Along with Jean de Dunois, La Hire was involved in scouting and skirmishing in the countryside as far north as Paris. In 1427, both La Hire and Dunois relieved the siege of Montargis. He was a close comrade of Joan of Arc. He was one of the few military leaders who believed in her and the inspiration she brought, and he fought alongside her at Orleans. At the Battle of Patay, La Hire commanded the vanguard and won a great victory for France. La Hire was also known for praying before going into battle, something that could be attributed to Joan's influence. In 1430, La Hire captured the English held fortification of Château Gaillard. He was imprisoned in Dourdan in the spring of 1431. He won the Battle of Gerberoy in 1435 and was made Captain General of Normandy in 1438. His last two major military engagements occurred in 1440 at Pontoise where he assisted Dunois to capture it from the English; and in 1442 he assisted Charles of Orleans in capturing La Réole. He died at Montauban on 11 January 1443, of an unknown illness.

Example Input: Question: How old was the Ottoman commander during the siege when the Russian Army achieved victory at Uzunahmet? Passage: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.
