Question: How old was the Duke of Saxony when he appointed Adolf I to hold Holstein and Stormarn? Passage:He was appointed to hold as fiefs Holstein and Stormarn, including Hamburg, by Lothair, Duke of Saxony, in 1111. By this appointment Adolf became the leader of the defence of Germany against the Wagri. Allied with Henry, the prince of the Obotrites, he repeatedly waged war on Wagria and the Rugians. After Henry's death (1127), Adolf remained allied with his sons Canute and Sventepolk, but they were soon dead and Lothair, by then King of Germany, had made Canute Lavard, a Danish prince, Duke of Schleswig. Feeling his authority threatened by the Danish upstart, Adolf attacked his castle of Albergs, captured the garrison, and destroyed its defences. He left his counties intact to his second son, Adolf II, since his eldest, Hartung, had been killed in the Second Battle of Chlumec in 1126.

Question: In what country is the Nikos Kazantzakis Stadium located? Passage:The "Nikos Kazantzakis" Stadium (), formerly known as Ergotelis Stadium and more commonly as Martinengo Stadium, is a football stadium located on the Martinengo bastion, part of the fortifications of Heraklion, on the island of Crete. It is named after Modern Greek literature giant Nikos Kazantzakis, whose grave is also located on the same bastion. It is part of the Ergotelis Athletic Centre, a sport facilities complex owned by Greek multi-sport club Ergotelis. Built in 1946, as Ergotelis Stadium (), it was the traditional home ground of Greek football club Ergotelis until 2004, when the club moved to the Pankritio Stadium, Heraklion's largest and most modern sports venue. The complex currently houses the Ergotelis Youth Academy, the largest youth sports academy on the island of Crete, and one of the largest in Greece, while the stadium itself is still used as the home ground of multiple Heraklion football clubs playing in the Heraklion Football Clubs Association amateur league system. It has a capacity of about 1,000 spectators, of which approximately 600 can be seated.

Question: How old was the general who led the first battalion in the Peninsula War when he died? 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.
