Question: How many battles had Oswald Watt commanded by the year Holden joined the Australian Imperial Force? Passage:Holden enlisted in the Australian Imperial Force on 26 May 1915, and was posted to the 4th Light Horse Brigade as a private. He departed for Egypt aboard the transport A29 Suevic on 13 June. Serving as a driver first in the Middle East and then on the Western Front, his mechanical ability and sense of adventure led him to volunteer for the Australian Flying Corps (AFC) in December 1916. After qualifying as a pilot in England, he was commissioned a lieutenant and posted to No.2 Squadron. Commanded by Major Oswald Watt, No.2 Squadron's personnel included many former Lighthorsemen, as well as mechanics from the AFC's first combat formation, the Mesopotamian Half Flight. The force trained extensively in England commencing in January 1917, before deploying to the Western Front that September. Holden was involved in the AFC's first day of combat in France; just after noon on 2 October, in the vicinity of Saint-Quentin, he and his wingman engaged a German two-seater that managed to escape.

Question: How old was Bill when his band began a ten year break? Passage:Flags is a 1985 album by the duo Moraz-Bruford.

During the recording of this album, Moraz was a member of The Moody Blues, while Bruford's band King Crimson had just begun a hiatus that would last for ten years. Flags features ten instrumental works, including a drum solo based on Max Roach's "The Drum Also Waltzes".

Question: Who is the wife of the coach that made it clear that Cornelius would be the starting quarterback in 2018? Passage:At the beginning of the 2018 season, head coach Mike Gundy made it clear that Cornelius would be the starting quarterback over transfer Dru Brown and true freshman Spencer Sanders.

His first real test came on September 15th in a game against the 17th ranked Boise State Broncos. Cornelius threw for 243 yards and 1 touchdown while adding the game-sealing touchdown on the ground. This win bumped the Cowboys up to number 15 in the Associated Press rankings. After losing 3 of the next 4 games, the Cowboys sat at 4-3 when the Texas Longhorns came to Stillwater. Cornelius shined on national TV, throwing for 321 yards and 3 touchdowns and adding 2 more rushing touchdowns en route to a 3835 win. Two weeks later, the Cowboys went on the road to Norman, Oklahoma to take on the Oklahoma Sooners in the yearly Bedlam Series. Cornelius went toe-to-toe with future number 1 overall pick Kyler Murray. He threw for a Bedlam school record 501 yards and 3 touchdowns. On the last offensive play of the game, Cornelius under threw star wideout Tylan Wallace, ending any upset bid the Cowboys had going. The very next week on November 17, the 9th ranked West Virginia Mountaineers visited Stillwater for the final home game of the year. On Senior Day, Cornelius led Oklahoma State to a come from behind upset victory over the Mountaineers, out-dueling Will Grier. He threw for 338 yards and 5 touchdowns and had 106 yards rushing and 1 rushing touchdown. This is widely considered to be his greatest game as a Cowboy. After a season finale loss against TCU, Cornelius led the Cowboys to the Liberty Bowl against Drew Lock and the Missouri Tigers. The Cowboys would win this game to finish 76, with Cornelius throwing for 336 yards and 4 touchdowns.
