Question: How many soldiers died in the battle that Stanley missed due to illness? Passage:He fought at several battles in Missouri, including the Battle of Wilson's Creek, where he guarded the supply trains. President Abraham Lincoln appointed Stanley as brigadier general September 28, 1861, although the U.S. Senate did not confirm the appointment until March 7, 1862. Fighting in the Western Theater, he participated in the operations against New Madrid, Missouri and the Battle of Island Number Ten. He was involved in numerous major battles, including the Second Battle of Corinth, where he commanded a division of infantry of the Army of the Mississippi, and the Battle of Stones River, in which he led the cavalry of the Army of the Cumberland. On March 11, 1863, Stanley was appointed major general to rank from November 29, 1862. Stanley also led the Union cavalry in the Tullahoma Campaign. He fell ill late in 1863 and missed the Battle of Chickamauga. In 1864, he fought under William Tecumseh Sherman as a division commander in the IV Corps of the Army of the Cumberland during the Atlanta Campaign, and he was promoted to command of the corps when Maj. Gen. Oliver O. Howard was named commander of the Army of the Tennessee. After the capture of the city, instead of employing him marching to the sea, Sherman dispatched Stanley and his IV Corps to Tennessee to help protect the state from invasion by John Bell Hood's Army of Tennessee.

Question: Was the population of Canberra greater than that of Adelaide the year Burbidge was appointed assistant agronomist at Waite Agricultural Research Institute? Passage:In 1943 she was appointed assistant agronomist at the Waite Agricultural Research Institute in Adelaide, where she started working on native pasture species for arid and semi-arid South Australia. She was appointed to the new position of systematic botanist at the CSIRO Division of Plant Industry, Canberra in 1946. At CSIRO she worked on organising and extending the herbarium, first as a research scientist and then as curator and was responsible for laying the foundations of the Herbarium Australiense, later the National Australian Herbarium. She wrote Key to the South Australian species of Eucalyptus L'Hér. but had not specialised on the genus. Her professional interest in systemic botany was reflected by her tenure as secretary of the systematic botany committee of the Australian and New Zealand Association for the Advancement of Science from 1948 to 1952. She also edited Australasian Herbarium News until her until 1953, when she took a years leave to be the Australian Botanical Liaison Officer at the Kew Gardens herbarium. While at Kew she photographed and indexed type specimens of Australian plants and made microfilm copies of Robert Brown's notebooks for Australian herbaria.

Question: Does Amtrak go into Canada? Passage:Everett Station is served by six daily Amtrak trains: four Cascades runs between Seattle and Vancouver, British Columbia, and two Empire Builder runs between Seattle and Chicago. The station is also served by the North Line of Sound Transit's Sounder commuter rail service, running four trains in peak direction towards King Street Station in Seattle during the morning commute and four trains from Seattle during the evening commute, only on weekdays and during special events. Train service to Everett is most often disrupted and canceled during the autumn and winter seasons because of landslides along the shoreline of the Puget Sound, where the BNSF mainline tracks run. During the 2012–2013 winter season, a record-high of 206 passenger trains between Everett and Seattle were canceled, prompting the Washington State Department of Transportation to begin a three-year landslide mitigation project in 2013 that will stabilize slopes above the railroad between Seattle and Everett.
