question: In December 1774, a Siamese supported rebellion broke out at Lampang in Lan Na, and soon spread. On 15 January 1775, the rebels took Chiang Mai, and overthrew the Burmese installed government. In November 1775, two Burmese armies of 35,000 were to invade Lan Na and Siam. But because of a mutiny by a senior commander, the southern army lost a significant portion of the troops. The remaining Burmese armies fought their way in. The northern army managed to capture Chiang Mai, albeit at a great cost, and the southern army took Sukhothai and Phitsanulok in central Siam. However, the invasion forces were too small to overcome the Siamese defences, and were bogged down. The armies withdrew in June 1776 after Hsinbyushin died. Hsinbyushin's successor Singu stopped the war with Siam, and demobilised much of the army. The decision was well received by the war-torn country. The people had grown tired of constant conscriptions to fight in "ever-lasting wars" in remote regions they had never heard of. But the king had unwittingly given up Chiang Mai, which proved to be the end of two centuries of Burmese rule there. Likewise, Singu took no action in 1778 when Vientiane and Luang Prabang stopped paying tribute, and came under Siam's sphere of influence.
Answer this question: How many years passed between the rebellion at Lampang in Lan Na and the death of Hsinbyushin?
answer: 2

question: The only region in which Singu maintained military action was Manipur, where he inherited another war from his father. The former Manipuri king Jai Singh, whom the Burmese last drove out in 1770, made four more attempts to oust the Burmese nominee between 1775 and 1782 from his base in Cachar. The Burmese drove him back each time but were unable to capture him. The army gained "barren victories" in Cachar and Jaintia where the rajas of the two small states agreed to pay a token tribute. But the tribute came at a high cost: the army lost 20,000 men, partly by fever over the years. After Singu's dethronement in 1782, the new king, Bodawpaya stopped the invasions. Manipur was again independent.
Answer this question: How many years has the Burmese four attempts to oust the nominee from his base in Cachar lasted?
answer: 4

question: The Navarrese Civil War of 1451-1455 pitted John II of the Kingdom of Navarre against his son and heir-apparent, Charles IV. When the war started, John II had been King of Navarre since 1425 through his first wife, Blanche I of Navarre, who had married him in 1420. By the marriage pact of 1419, John and Blanche's eldest son was to succeed to Navarre on Blanche's death. When Blanche died in 1441, John retained the government of her lands and dispossessed his own eldest son, Charles , who was made Prince of Viana in 1423. John tried to assuage his son with the lieutenancy of Navarre, but his son's French upbringing and French allies, the Beaumonteses, brought the two into conflict. John was supported by the Agramonteses. From 1451 to 1455, they were engaged in open warfare in Navarre. Charles was defeated at the Battle of Aybar in 1452, captured, and released; and John tried to disinherit him by illegally naming his daughter Eleanor, who was married to Gaston IV of Foix, his successor. In 1451, John's new wife, Juana Enriquez, gave birth to a son, Ferdinand. In 1452, Charles fled his father first to France, where vainly sought allies, and later to the court of his uncle, John's elder brother, Alfonso V at Naples. Charles was popular in Spain and John was increasingly unpopular as he refused to recognise Charles as his "first born", probably planning to make Ferdinand his heir. The Navarrese Civil War presaged the Catalan Civil War of 1462-72, in which John's ill-treatment of Charles was a precipitating event.
