Question: How old was Yoshinaka when Enichi-ji's general was killed? Passage:Enichi-ji was opened in 807 by the Hosso sect scholar-monk Tokuitsu, who had come from Nara to spread the faith in the Aizu region. He overcame the followers of the Tendai and Shingon sects to become preeminent in Aizu, and by the time of his death in 842, the temples was a complete Shichido garan with 300 monks in residence, several thousand sohei and more than 3500 sub-temples. By the late Heian period, the temple had extended its holdings into eastern Echigo province and had established close ties with the Taira clan. During the Genpei War, the temple sent troops in support of the Heike in Shinano Province against Kiso Yoshinaka. However, the temple's leading general, Jotan-bo, was killed at the 1181 Battle of Yokotagawa by Yoshinaka's forces, and the temple's forces withdrew and the temple went into decline.

Question: How many miles long is the river that Silvanus drove the Alamanni tribesmen back from? Passage:Silvanus was born in Gaul, the son of Bonitus, a Laetic Frankish general who had supported Constantine I in the civil war against Licinius. Like so many other Franks of his times, and like his father before him, he was a loyal and thoroughly romanized "barbarian" in the military service of the Empire. By AD 351, he held the rank of tribune and was one of the senior officers who defected to Emperor Constantius II at the Battle of Mursa Major, after initially supporting the usurper Magnentius. An able soldier, Silvanus was eventually promoted to the rank of Magister militum per Gallias, a crucial post, then in AD 352-353, Constantius personally entrusted him with the difficult task of driving the Alamanni tribesmen raiding and looting in Gaul back beyond the Rhine, and restoring the fast eroding Roman authority in the province. This Silvanus fulfilled partly by bribing the Alamanni chieftains with the taxes he had collected, partly by defeating the Alamanni in battle and partly by suppressing the local bagaudae insurrections flaring up again in central and northern Gaul.

Question: What were the names of the five storms formed before Tropical Storm Fay during the 2008 Atlantic hurricane season? Passage:Tropical Storm Fay was a strong and unusual tropical storm that moved erratically across the state of Florida and the Caribbean Sea. The sixth named storm of the 2008 Atlantic hurricane season, Fay formed from a vigorous tropical wave on August15 over the Dominican Republic. It passed over the island of Hispaniola, into the Gulf of Gonave, across the island of Cuba, and made landfall on the Florida Keys late in the afternoon of August18 before veering into the Gulf of Mexico. It again made landfall near Naples, Florida, in the early hours of August19 and progressed northeast through the Florida peninsula, emerging into the Atlantic Ocean near Melbourne on August20. Extensive flooding took place in parts of Florida as a result of its slow movement. On August21, it made landfall again near New Smyrna Beach, Florida, moving due west across the Panhandle, crossing Gainesville and Panama City, Florida. As it zigzagged from water to land, it became the first storm in recorded history to make landfall in Florida four times. Thirty-six deaths were blamed on Fay. The storm also resulted in one of the most prolific tropical cyclone related tornado outbreaks on record. A total of 81 tornadoes touched down across five states, three of which were rated as EF2. Damage from Fay was heavy, estimated at $560 million.
