Question: How many years were The Screamers together before Roessler joined the band? Passage:Paul Roessler was born on August 27, 1958, in New Haven, Connecticut. In 1974, he moved to West Los Angeles where he met and befriended future Germs band members Darby Crash and Pat Smear at University High. After graduating from high school, Roessler went on to study classical music at California State University, Northridge, for a few semesters before leaving in early 1978 to join innovative electropunk band, The Screamers. After two successful years, The Screamers found themselves rapidly disintegrating as a band, causing Roessler to leave in January 1980, and would then go on to play in Nervous Gender with former Germs drummer Don Bolles as well as in Geza X and the Mommymen. After a few months of going between bands, he was recruited by Nina Hagen to join her for an upcoming European tour. After touring Europe and America with Hagen, they recorded Nunsexmonkrock. Before Roessler's second tour with Hagen, Pat Smear from the Germs joined the band. Later, when Smear left the band, Roessler left also. In 1981, he formed the band Twisted Roots with Smear and sister Kira Roessler. During this time, he was playing with 45 Grave, Josie Cotton, DC3 (with Dez Cadena of Black Flag) and Crimony (with Mike Watt) as well. Roessler was also doing sessions with many other bands such as the Dead Kennedys and Saccharine Trust. Roessler has continued to work with Nina Hagen and Josie Cotton. From 1998 to 2011, Roessler worked as the in-house producer at Satellite Park Studio with Geza X. In 2006, Roessler released an autobiographical poetry book entitled Eight Years (Brass Tacks Press, 2006). He continues to write his own music and is currently recording a new album. In 2010, Roessler produced and played keyboards on Nina Hagen's gospel album Personal Jesus (Universal). He has been a member of the Fancy Space People with Don Bolles and Nora Keyes since 2009. In October 2011, they joined the Smashing Pumpkins on their "Other Side of the Kaleidyscope" tour.

Question: In what year was the Battle of Leyte Gulf? Passage:On 20 October, D-Day for the Leyte landing forces, Mertz escorted landing craft through air attacks to the beach and later in the day patrolled off Dinagat Island at the entrance to Leyte Gulf. Early in the morning of 25 October as the Japanese Southern Force approached Leyte Gulf through the Mindanao Sea, Mertz and patrolled between Desolation Point and Homonhon Island, lest the enemy fleet choose to steam north along the east coast of Dinagat Island to attack the Allied beachhead. When the Japanese entered Surigao Strait, Rear Admiral Jesse B. Oldendorf’s force met and destroyed the enemy armada in the classic “crossing-of-the-T” maneuver known as the Battle of Surigao Strait, part of the overall Battle of Leyte Gulf. Later that same day Mertz splashed a Zero at several hundred yards with heavy machinegun fire.
