Example Input: Question: How many people died in the battle that the 1st battalion saw action at in August 1807? Passage:A second battalion was raised in 1804 to increase the strength of the regiment. The 1st battalion embarked for Copenhagen in July 1807 and saw action at the Battle of Copenhagen in August 1807 during the Gunboat War before returning home in November 1807. It then embarked for Portugal in May 1808 for service under General Sir Arthur Wellesley in the Peninsular War and saw action at the Battle of Roliça in August 1808 and the Battle of Vimeiro later that month. In January 1809 the battalion took part in the Battle of Corunna, carrying out successive bayonet charges to keep the French at bay to which General Sir John Moore shouted "Well done, 50th! Well done, my Majors!". The battalion was subsequently evacuated from the Peninsula. Both battalions then embarked from the Downs in July 1809 and saw action in the disastrous Walcheren Campaign. It was the last regiment to leave Holland in December 1809.

Example Input: Question: How long had the Nevada District Court existed before Sanford appeared there? Passage:Following his arrest, Sandford was held in the Nevada Southern Detention Center. Due to his mental health conditions, Sandford was kept in solitary confinement and repeatedly put under suicide watch. On June 20, 2016, a complaint was filed with the United States District Court for the District of Nevada charging Sandford with committing an act of violence on restricted ground. Sandford appeared in a Nevada District Court on June 20, 2016, where he was charged with committing an act of violence on restricted ground. Sandford's public defender, Heather Fraley, argued that Sandford should be bailed to a halfway house given his lack of a criminal record, but he was denied bail by judge George Foley Jr. on the basis that he presented a flight risk and was a potential danger to the community. On June 29, a federal grand jury responded to an indictment filed by United States Attorney Daniel Bogden by charging Sandford with three felonies: two counts of being an illegal alien in possession of a firearm and one count of impeding and disrupting the orderly conduct of government business and official functions. Each charge carried a maximum sentence of 10 years' imprisonment and a fine of $250,000. U.S. Immigration and Customs Enforcement also issued a detainer against Sandford relating to an immigration violation.
