input: In 1831 a runaway convict named George Clarke, who had lived with Aborigines in the area for several years, claimed that a large river called Kindur flowed north-west from the Liverpool ranges in New South Wales to the sea. Charles Sturt believed that the Murray-Darling system formed the main river system of New South Wales and Mitchell wanted to prove Sturt wrong. Mitchell formed an expedition consisting of himself, assistant surveyor George Boyle White and 15 convicts who were promised remission for good conduct. Mitchell took 20 bullocks, three heavy drays, three light carts and nine horses to carry supplies, and set out on 24 November 1831 to investigate the claim. On reaching Wollombi in the Hunter Valley, the local assistant surveyor, Heneage Finch, expressed a desire to join the expedition. He had established his credentials by surveying a route from Sydney to Wollombi, so Mitchell approved his request, provided he obtained extra supplies and men, and he followed along later.  The expedition continued northward, climbed the Liverpool Range on 5 December, and made Quirindi on 8 December. Shortly afterwards Finch arrived but inexplicably had not brought provisions, so Mitchell immediately sent him back to get them. By 11 December the expedition had reached Wallamoul Station near Tamworth, the northern extent of white settlement at the time.  Mitchell continued his northward push into new territory, taking local Kamilaroi people to assist in finding water and to express his peaceful intentions. By early January 1832 he was in the vicinity of the present town of Narrabri, reached the Gwydir River in mid-January, and found the Barwon by the end of the month, where he set up camp. Mitchell left the main party and made a reconnaissance down the Barwon until he found its junction with the Gwydir. After Mitchell returned to the main camp, Finch arrived with tragic news. He had been travelling with three convicts and provisions but, because of a shortage of water, the group had separated. He left two men behind while he attempted to locate the main expedition. Having failed to do that, on the second day he returned to the campsite to discover that it had been ransacked. Supplies were scattered and beneath the wreckage were two dead men. The immediate effect was that Mitchell decided to abandon the expedition and return south. The party reached the Gwydir on 8 February and was near the site of the attack on 17 February. Mitchell buried the two bodies and salvaged some equipment. Once back at Wallamoul, Mitchell placed White in charge of the main party, while he returned hastily to Sydney. He was satisfied that there was no truth about the river Kindur claimed by Clarke. Fourteen years after the attack, Mitchell revealed that the convicts had indulged in sexual relations with Aboriginal women.

Question: Time Squad is an American children's animated television series created by Dave Wasson for Cartoon Network, and the 10th of the network's Cartoon Cartoons. It follows the adventures of Otto Osworth, Buck Tuddrussel, and the robot Larry 3000, a trio of hapless "time cops" living in the far distant future who travel back in time attempting to correct the course of history. During their adventures, they run into major historical figures such as Julius Caesar, Abraham Lincoln, Sigmund Freud, Leonardo da Vinci, the Founding Fathers, and Montezuma, who have taken a drastically different course of life than history dictates. The mission of the Time Squad is to guide these figures onto the correct path and ensure the integrity of the future.

Otto Osworth (voiced by Pamela Adlon): An orphan illegally traveling along with Tuddrussel and Larry, taken on board due to their incompetence and his impressive historical knowledge (and for Otto to escape his brutal life at the orphanage). Despite being a bookworm, his demeanor is far from boring; he is just as childlike and jocular as any regular eight-year-old. Even though he is the youngest, he is also the most responsible out of the squad, being the only one pure enough to not let himself get swayed by temptations. Depending on who he's siding with, he can either become loud and destructive (when Tuddrussel has him company) or composed and calm (when it's Larry he agrees with). It's unknown what happened to Otto's parents.  Lawrence "Larry" 3000 (voiced by Mark Hamill): A grumpy robot and the only one on board able to operate the computer. It's his job to make sure the squad ends up at the right time and place. Initially, he was programmed as a polyglotic robot for diplomatic purposes; when all of the nations rejoiced into one, huge country, his consular abilities were no longer needed. Larry is famous for his effeminate behaviour and interests, which are portrayed all but subtly. Unusually, he is extremely dramatic and open in showing his emotions whilst still being the snarkiest of the trio. He prides himself in having knowledge of proper etiquette and manners. For Otto, he has been repeatedly depicted as a maternal figure.  Beauregard "Buck" Tuddrussel (voiced by Rob Paulsen): An immature time cop, who possesses all the physical requirements for his job and none the intellectual. Whenever there's someone who needs a beating up (and even when they don't), he's the best person to get assigned for such a task. Impulsiveness, aggressiveness and air-headedness are traits which define Tuddrussel quite nicely. Not much of his backstory is known, aside from his Southern heritage and a short-lived marriage to fellow time cop Sheila Sternwell.
