Passage:In 1933, Ottwalt and his wife, Waltraut, left Germany and went into exile in Denmark, then, by way of Czechoslovakia, ended up in the Soviet Union. Living in Moscow, Ottwalt wrote for the German exile magazine Internationale Literatur (published by Johannes R. Becher) and was an editor at Vegaar Bibliothek. He also wrote for the Deutsche Zentral Zeitung. In 1936, he and his wife were ensnared in the Stalinist purges and arrested by the Soviet secret police, the NKVD. He was charged with suspicion of espionage, sentenced to forced labor and deported to a gulag near Archangelsk. His wife was sentenced to forced labor in Kotlas. She was deported back to Germany in January 1941 and didn't learn about his death until January 1958, when the Soviet Red Cross informed her that her husband had died on 24 August 1943.

Input: Consider Input: Question: What is the population of the city that headquartered  Combined Forces Command - Afghanistan in 2004? Passage:Early in the Global War on Terror, Fontes served at US Central Command J5 overseeing issues of political-military cooperation in Afghanistan. In June 2004, she was moved to Combined Forces Command - Afghanistan headquarters in Kabul and served under David Barno as the head of the CJ5 staff for political-military coordination. Her staff was responsible for keeping General Barno "on message", overseeing the policies impacting military operations, and performing liaison work with both the Afghan Ministry of Defense and United Nations Assistance Mission in Afghanistan. At the end of her first year in Afghanistan and following Karl Eikenberry's assumption of command from Barno, Fontes volunteered to lead the Provincial Reconstruction Team (PRT) in Tarinkot. Daniel Green, the political adviser for the PRT, reported that though some Soldiers at the PRT had initial concerns due to her gender, those worries were shortly put to rest. She had been active in engaging with the Afghan people. Green said that Fontes, then a Lieutenant Colonel, pitched in a few hundred dollars of her own money to host a lunch on the PRT for local Afghan leaders. An article in Vanity Fair relates a story that she once refused to depart a meeting with Afghan elders in Chora District under threat of small arms fire, for fear of appearing weak in the face of the Taliban. Green asserts that in early 2006, she survived the first suicide vehicle-borne improvised explosive device attack in Urozgan Province due in part to the device's failure to detonate all of the mortar shells of which it was comprised. She departed Afghanistan in May 2006 to attend the US War College, graduating in 2007. She had been promoted that year to colonel. She was subsequently assigned as the chief of the American Security Assistance Office in Pakistan.

Passage:The tomb was originally a monumental temple at Golyama Kosmatka Mound, built in the second half of the 5th century BC. After extended use as a temple, at the later part of the 3rd century BC, Seuthes lll was buried inside. The sarcophagus-chamber contained personal belongings that were necessary for the afterlife of the King.

There are bronze vessels, and three big ceramic amphora which were filled with thick Thracian wine. The floor and the ritual bed are covered by a carpet woven in gold thread. The total weight of the gold including all the objects is more than one kilogram. There are thirteen gold appliques for horse halters with images of human, animals and plants - objects which are rare in Thracian archaeology. Another two rectangular objects are golden with figures of standing warriors, used as a decoration for the sword sheath. There is a massive circular decoration for the King's armour. The handle of the rod is also golden. In the grave are placed golden vessels with two handles for drinking wine, also called kiliks, and a remarkable golden wreath with twigs, leaves and acorns and many other items.
