These are the first words on an historic marker at the Black Hawk Historic Site in Rock Island. "The marker states that La Main Cassee was 'a true friend of the American cause during the Revolutionary War' who confronted a British war party here in 1779. The same marker then commemorates the burning of Saukenuk by the American military in 1780."

George Davenport traveled with an army expedition in 1816 to establish a frontier military outpost on the Mississippi River. The outpost would be built on a wooded island within several miles of Native American villages. The military estimated that 10,000 people lived these villages.

Agatha Beiderbecke asked a close family friend, Albert Petersen, to listen to her seven-year-old son play the piano. According to the biography Bix, Man and Legend, Petersen could hardly contain his enthusiasm. “Agatha, this boy has something.” He said. “Keep me informed about his progress – and whatever you do, get him some piano lessons.” One might expect a friend – and her cousin’s husband – to be encouraging. But Petersen was also one of Davenport’s leading musicians, bandleaders, and teachers. He also began his career in music at a young age.

A life-size bronze sculpture, Lincoln with Boy on Bridge, stands in downtown Davenport’s Bechtel Park near the Arsenal Bridge. Abraham Lincoln stands on a railroad track gazing forward; a seated boy looks up to him. Jeff Adams’ sculpture depicts a small moment between events that brought America closer to Civil War.
