Input: Consider 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 Rolica 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.

Input: Consider Input: Question: Who won gold in the Olympics for Women's pole vault the year that Murer underperformed due to her poles being misplaced? Passage:Fourteen athletes qualified at 4.55, but two were unable to get over the opening height of 4.50 in the finals. Minna Nikkanen set her National Record at 4.60, but there were still seven in at 4.70, five of them with clean rounds to that point making for a five-way tie including Angelica Bengtsson's National Record and returning silver medalist Jenn Suhr, who had confidently passed to 4.60. 4.80 decided the medalists with Nikoleta Kyriakopoulou taking it on the first attempt to take over the lead. 2011 champion Fabiana Murer took it on her second attempt and was ahead of Yarisley Silva who had struggled earlier at 4.70. Both Silva and Murer made 4.85 on their first attempt, giving Murer the lead. Murer also again equalled her own South American record. Kyriakopoulou missed at what would have been her National Record. Having no strategic advantage to clearing it with one miss, she passed to 4.90. Everybody missed their first two attempts at 4.90, making Kyriakopoulou the bronze medalist. On her final attempt, Silva made it, to leap past Murer into gold medal position. Murer was unable to answer on her final attempt and had to settle for silver. Murer was pleased to win a medal in Beijing seven years after the 2008 Olympics, where she underperformed following her poles being misplaced by the organization, and became optimistic for the 2016 Summer Olympics at her own Brazil, when she will have to set a masters world record to be in the medal hunt.
