Background: Canby was born in Piatt's Landing, Kentucky, to Israel T. and Elizabeth (Piatt) Canby. He attended Wabash College, but transferred to the United States Military Academy, from which he graduated in 1839. He was commissioned a second lieutenant in the 2nd U.S. Infantry and served as the regimental adjutant. Although often referred to as Edward Canby, a biographer has suggested that he was known as "Richard" during childhood and to some friends for most of his life.
Context: In August 1872, Canby was posted to command the Pacific Northwest. He soon faced problems with the Modoc tribe, who had traditionally lived in Northern California. Forced to remove to a reservation in Oregon which they had to share with their traditional enemies, the Klamath tribe, they had pleaded with the US government to return to California. When the US refused, the Modoc left the reservation and returned illegally. In 1872, the US Army went to fight against them to force them back and the Modoc War broke out. The Modoc, entrenched in Captain Jack's Stronghold south of Tule Lake, resisted army attacks and fought US forces to a stalemate.  General Canby had received conflicting orders from Washington as to whether to make peace or war on the Modoc. As war was not working, the US government authorized a peace commission and assigned Canby a key position on it. There were many lines of communication between the Modoc and whites. At one point, someone told the Modoc leader Captain Jack that the governor of Oregon intended to hang nine Modoc, apparently without trial, as soon as they surrendered. The Modoc broke off scheduled talks; Canby was angered by the rumors and their action, as he believed that his federal authority trumped the governor's and made the threat irrelevant. Canby had no intention of allowing the Modoc to be punished without a trial.  On April 11, 1873, after months of false starts and aborted meetings, Canby went to another parley, unarmed and with some hope of final resolution. Judge Elijah Steele of Yreka, California wrote later that when he warned Canby that the Modoc were volatile and he was at risk, Canby replied, "I believe you are right, Mr. Steele, and I shall regard your advice, but it would not be very well for the general in command to be afraid to go where the peace commissioners would venture." The peace talks were held midway between the army encampment and Captain Jack's stronghold near Tule Lake. It was discovered later that two members of Canby's party brought concealed weapons and Modoc warriors were also armed.  According to Jeff C. Riddle, the Modoc son of the US interpreter and the author of Indian History of the Modoc War (1914), the Modoc had plotted before the meeting to kill Canby and the other commissioners, as they believed peace was not possible. They were determined to "fight until we die." (He was the son of Winema and Frank Riddle.) Captain Jack had been reluctant to agree to the killings, believing it "coward's work", but was pressured by other warriors to agree. He insisted on being given another chance to ask Canby to "give us a home in our country." When Canby said he did not have the authority to make such a promise, Captain Jack attacked the general. With Ellen's Man, one of his lieutenants, he shot Canby twice in the head and cut his throat. The Modoc also killed Reverend Eleazar Thomas, a peace commissioner, and wounded others in the party. Canby was the only general to be killed during the Indian Wars.
Question: What was his final assignment?
Answer: the Modoc had plotted before the meeting to kill Canby and the other commissioners, as they believed peace was not possible.

Problem: Background: Yen was born in Guangzhou, China. His mother, Bow-sim Mark, is a Fu Style Wudangquan (internal martial arts) and Tai Chi grandmaster, while his father, Klyster Yen (Zhen Yun Long ), is a newspaper editor. When he was two years old, his family moved to Hong Kong and then to Boston when he was 11. His younger sister, Chris Yen, is also a martial artist and actress, and appeared in the 2007 film Adventures of Johnny Tao: Rock Around the Dragon.
Context: Donnie Yen was a rebel when he was young due to the huge expectations and pressures from his parents, as his mother is the founder of the Chinese Wushu Research Institute in Boston, and his father was a scholar and a musician. Yen joined a Chinatown gang in Boston, MA, in his early years. He was a very curious teenager who sought to exchange martial arts knowledge with people from different martial arts backgrounds, which led to him gaining profound knowledge in practical martial arts and having a reputation as a street brawler.  One reported occasion confirms Yen as being an efficient martial artist. According to news reports by Hong Kong news channels in the late 1990s, Yen was at a nightclub with his then girlfriend, Joey Meng. Inside the nightclub, Joey was harassed by a troublesome gang that had taken an interest in her. Yen warned them to leave her alone, but they persisted to cause trouble. As Yen and Joey left the club, the gang followed and attacked Yen. Yen beat up eight members of the gang who were later hospitalized.  Malaysian Martial Arts Star Michelle Yeoh has said that Donnie Yen is the fastest guy she has worked with. Other martial arts stars such as Jackie Chan and Jet Li have also stated that Yen may be the best fighter in terms of practical combat in the Asian cinematic universe.  World class fighters, such as former Strikeforce Middleweight Champion Cung Le and former World Boxing Heavyweight Champion Mike Tyson, who have worked with Donnie Yen in the films Bodyguards and Assassins and Ip Man 3, respectively, have both claimed that Donnie Yen is an incredible martial artist and would do well in authentic combat. While filming Ip Man 3, crew members were afraid that Mike Tyson, who had been a professional boxer, would forget the choreography and throw real punches to injure Yen. However, it was ultimately Yen who fractured Tyson's finger while using his elbow to block Tyson's punches.
Question: Were there any other fights he was in?
Answer:
Jackie Chan and Jet Li have also stated that Yen may be the best fighter in terms of practical combat in the Asian cinematic universe.
