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.

Question: How long did Milo's uncle serve in the U.S. Congress? Passage: November 1915, von Brincken married again to the San Francisco socialite Milo Abercrombie (1895-1977). Born in Houston, Texas, Milo was the niece of John W. Abercrombie, U.S. congressman from Alabama and acclaimed by noted portraitist Harrison Fisher as "California's greatest beauty". They had two children, Wilhelm Friedrich (1918-1980) and Maria A. (1917-2010). She divorced von Brincken in 1919 during his imprisonment and legally changed her and their two children's last name back to her maiden name, Abercrombie, so her children would not be "ashamed" of their name. Despite the divorce, von Brincken remained devoted to his former wife and she was able to remarry again, thanks to him. When the Roman Catholic Church forbade Abercrombie's intended marriage to U.S. Navy lieutenant Lyman K. Swenson, due to her divorce, von Brincken came forth and disclosed his earlier marriage to Alice Roedel. As both Roedel and von Brincken were Catholic, that marriage was sanctioned by the Church. Thus, the Church did not recognize von Brincken's later marriage to Abercrombie. Abercrombie and Swenson, who had both refused to marry unless it was sanctioned by the Catholic Church were then free to wed. Abercrombie and Swenson were married on August 11, 1920 by Father John Byrne at St Mary's Cathedral in San Francisco. At the wedding dinner that night, von Brincken's young son with Abercrombie, referred to as "John" and "Buster" in the press, was a "guest of honor" and toasted by his new stepfather and the officers of the submarine H-6 that he commanded, pledging, "the little chap's future to the uniform of blue." Swenson and Abercrombie had two children, Lyman K. Jr. ("Robert") and Cecilia. Abercrombie obtained an interlocutory decree of divorce from Swenson in May 1925, with the final decree a year later. Several months later, in October 1925, the newspapers speculated that Abercrombie would marry another naval officer, Lieutenant Commander Hugo W. Koehler, reputed to be the "wealthiest officer" in the Navy. The third generation of a wealthy St. Louis brewery family, Koehler had been a naval intelligence and U.S. State Department spy in South Russia during the Russian Revolution. Swenson had introduced Milo Abercrombie to Koehler in Honolulu. Koehler was in Panama with his ship, USS West Virginia (BB-48) when he read a newspaper account that he was engaged to marry Milo Abercrombie. Brushing it off, Koehler curtly told the press, "Some error," while Abercrombie did not take it so lightly. "I have been deeply humiliated", she told reporters, her eyes "wet with tears". "This is a most unkind blow of fate. I cannot possibly understand how this false rumor got about." Two years later, Koehler married Matilda Pell, the ex-wife of U.S. Congressman Herbert Pell (D-NY) and mother of future United States Senator Claiborne Pell (D-RI). In a bitter child visitation court battle in 1927 that went all the way to the California Court of Appeals, Abercrombie lost custody of her children with Swenson to him, after making baseless accusations that he had molested their four-year old daughter, Cecelia. The appellate court excoriated Abercrombie, "[I]in furtherance of a manifest determination to prevent him from ever seeing the children again, under any circumstances, she was instrumental in inspiring and promoting a scheme directly involving one of the children which had for its obvious purpose the ruination of respondent's character as a man, the bringing about of his complete disgrace as a naval officer, and the destruction of the love and affection which his children had theretofore manifested toward him." Swenson v. Swenson" (1929) 101 Cal.App. 440. In 1929, Lyman Swenson married Loretta B. Bruner (1897-1979). His son, Lyman K. Swenson Jr. ("Robert") (1923-2016) was also a US Naval officer.

Question: Which Mesopotamian civilization's city has the most people at its peak? Passage:A vast number of artifacts have been discovered from ancient Mesopotamia depicting explicit heterosexual sex. Glyptic art from the Sumerian Early Dynastic Period frequently shows scenes of frontal sex in the missionary position. In Mesopotamian votive plagues from the early second millennium BC, the man is usually shown entering the woman from behind while she bends over, drinking beer through a straw. Middle Assyrian lead votive figurines often represent the man standing and penetrating the woman as she rests on top of an altar. Scholars have traditionally interpreted all these depictions as scenes of ritual sex, but they are more likely to be associated with the cult of Inanna, the goddess of sex and prostitution. Many sexually explicit images were found in the temple of Inanna at Assur, which also contained models of male and female sexual organs, including stone phalli, which may have been worn around the neck as an amulet or used to decorate cult statues, and clay models of the female vulva.
