Question: Write an article that answers the following question: How many years after John of Ibelin was elected mayor did he die?
Article: Frederick had been King of Jerusalem—and as such claimed suzerainty over Cyprus—in right of his wife Isabella II until her death in 1228. That year he arrived first in Cyprus, where he antagonised the nobles, and then in Jerusalem, where he stayed until 1229, leaving in humiliating circumstances after having produced an anti-imperialist reaction in the people. In 1231 he sent Riccardo Filangieri as his marshal. His attempt to assert his authority was opposed by John of Ibelin, the Old Lord of Beirut, who had been regent until Frederick's arrival. On John's death in 1236 the war was taken up by his son Balian. In 1239 Philip of Montfort assumed the leadership of the opposition. Though the ecclesiastical hierarchy and the Knights Templar supported the nobility, the Teutonic Knights and Knights Hospitaller supported Filangieri. In general his rights as regent were recognised but his practical power was denied on the basis of the Assizes and the Haute Cour. His headquarters were in Tyre and he had the allegiance of Bohemond V, Prince of Antioch and Count of Tripoli. He also held the Holy City of Jerusalem itself, which had been negotiated away from the Saracens by Frederick. So long as the Ibelins controlled the opposition, Filangieri could count on the support of their enemies as well. The Italian cities were also divided between the two factions: Pisa supported Filangieri and Genoa the Ibelins. The Ibelins controlled Beirut, Arsuf, and Caesarea as well as the old capital of Acre. In 1231 the citizens of Acre formed a commune with their headquarters at the church of Saint Andrew's in order to unify their opposition to Filangieri. In 1232 John of Ibelin was elected its mayor.

Question: Write an article that answers the following question: How many more cannons did he have than river war vessels?
Article: Before Hunyadi could assemble his forces, the army of Mehmed II  arrived at Belgrade. The siege began on July 4, 1456. Szilágyi could rely on a force of only 5,000-7,000 men in the castle. Mehmed set up his siege on the neck of the headland and started heavily bombarding the city's walls on June 29. He arrayed his men in three sections: The Rumelian corps had the majority of his 300 cannons, while his fleet of 200 river war vessels had the rest of them. The Rumelians were arrayed on the right wing and the Anatolian corps were arrayed on the left. In the middle were the personal guards of the Sultan, the Janissaries, and his command post. The Anatolian corps and the Janissaries were both heavy infantry troops. Mehmed posted his river vessels mainly to the northwest of the city to patrol the marshes and ensure that the fortress was not reinforced. They also kept an eye on the Sava river to the southwest to avoid the infantry from being outflanked by Hunyadi's army. The zone from the Danube eastwards was guarded by the Sipahi, the Sultan's feudal heavy cavalry corps, to avoid being outflanked on the right.

Question: Write an article that answers the following question: How many hours did it take for the HV force to capture all of the plateau?
Article: On 21 June, the HV attacked RSK positions at the Miljevci Plateau, located in the pink zone north of Šibenik. The TO forces in the area were subordinated to the 1st Brigade of the TO, and Lieutenant Colonel General Milan Torbica. The HV deployed 250 troops, elements of the 113th and 142nd Infantry Brigades, commanded by Brigadier Kruno Mazalin. The HV had infiltrated the pink zone along three routes—via Nos Kalik, across the Čikola river and by boat sailing upstream along the Krka River, during the night of 20/21 June. The fighting began at 5 a.m. as the HV force, deployed in 26 squads, captured six out of seven villages on the plateau by the end of the morning. At 8:00 p.m., the HV captured the village of Ključ, and all of the plateau. The advance created a HV-held salient south of Knin, several kilometres deep. It also led the RSK artillery to bombard Šibenik and HV bombardment of Knin in response, both on 22 June. The artillery fire progressively intensified until 23 June, while the RSK mobilised and counterattacked against the HV positions at the Miljevci Plateau. However, the mobilisation yielded only 227 additional troops, and the counterattack failed. An UNPROFOR assessment concluded the situation might deteriorate further and engulf all of the pink zones. To address the situation, UNPROFOR military commander Lieutenant General Satish Nambiar met with Deputy Prime Minister of Croatia Milan Ramljak and Chief of the General Staff of the Armed Forces of the Republic of Croatia General Anton Tus in Zagreb the same day, in order to discuss the developments on the Miljevci Plateau. Skirmishes continued on 24 June, accompanied by some artillery fire. Morale of the RSK troops plummeted though, causing a TO garrison based in nearby Trbounj to abandon its barracks.
